The
Single Convention on Narcotic Drugs is an
international
treaty to prohibit production
and supply of specific (nominally
narcotic)
drugs and of drugs with similar effects except
under
licence for specific purposes, such as
medical treatment and research. As noted
below, its major effects included updating the Paris Convention of
13 July 1931 to include the vast number of synthetic opioids
invented in the intervening 30 years and a mechanism for more
easily including new ones. From 1931 to 1961 most of the families
of synthetic opioids had been developed, including drugs in
whatever way related to
methadone,
pethidine,
morphinans and
dextromoramide & related drugs; research
on
fentanyls and
piritramide were also nearing fruition at this
point.
Earlier treaties had only controlled
opium,
coca, and derivatives such as
morphine,
heroin and
cocaine. The Single Convention, adopted in 1961,
consolidated those treaties and broadened their scope to include
cannabis and drugs whose effects are
similar to those of the drugs specified. The
Commission on Narcotic Drugs
and the
World Health
Organization were empowered to add, remove, and transfer drugs
among the treaty's four Schedules of controlled substances. The
International
Narcotics Control Board was put in charge of administering
controls on drug production, international trade, and dispensation.
The
United Nations Office on Drugs and
Crime
(UNODC) was delegated the Board's day-to-day work
of monitoring the situation in each country and working with
national authorities to ensure compliance with the Single
Convention. This treaty has since been supplemented by the
Convention on
Psychotropic Substances, which controls
LSD,
Ecstasy, and other
psychoactive pharmaceuticals, and the
United Nations Convention Against Illicit Traffic in Narcotic Drugs
and Psychotropic Substances, which strengthens provisions
against
money laundering and other
drug-related offenses.
Influence on domestic legislation
Since the Single Convention is not self-executing, Parties must
pass laws to carry out its provisions.
The United
Nations Office on Drugs and Crime
works with countries' legislatures to ensure compliance. As a
result, most of the national drug statutes in the
UNODC's legal library share a high degree of
conformity with the Single Convention and its supplementary
treaties, the 1971
Convention on Psychotropic
Substances and the 1988
United Nations Convention Against Illicit Traffic in Narcotic Drugs
and Psychotropic Substances.
The Single Convention has been extremely influential in
standardizing national drug control laws.
In particular, the
United
States
' Controlled
Substances Act of 1970 and the United Kingdom
's Misuse of
Drugs Act 1971 were designed to fulfill treaty
obligations. Both Acts include analogous schemes of drug
Scheduling, along with similar procedures for adding, removing, and
transferring drugs among the Schedules. The Controlled Substances
Act follows the Single Convention's lead in granting a public
health authority a central role in drug Scheduling decisions. It
also includes a provision mandating that federal authorities
control all drugs of abuse at least as strictly as required by the
Single Convention(
21
U.S.C. §
811(d)).
As of January 2005, the Single Convention had 180 Parties.
History
The
League of Nations adopted
several drug control treaties prior to
World War II specifying uniform controls on
addictive drugs such as
cocaine,
opium, and its derivatives. However, the lists of
substances to be controlled were fixed in the treaties' text;
consequently, the conventions had to periodically be amended or
superseded by new treaties in order to keep up with advances in
chemistry. The cumbersome process of conference and state-by-state
ratification could take decades.
A
Canadian Senate committee report
notes, "The work of consolidating the existing international drug
control treaties into one instrument began in 1948, but it was 1961
before an acceptable third draft was ready." That year, the
UN Economic and Social
Council convened a
plenipotentiary conference of 73 nations for
the adoption of a single convention on narcotic drugs. Canadian
William B. McAllister, Q.C., notes that the participating states
organized themselves into five distinct caucuses:
- Organic states group: As producers of the
organic raw materials for most of the global drug supply, these
countries had been the traditional focus of international drug
control efforts. They were open to socio-cultural drug use, having
lived with it for centuries. While India
, Turkey
, Pakistan
and Burma
took the
lead, the group also included the coca-producing states of Indonesia
and the Andean region of South America, the opium-
and cannabis-producing countries of South
and Southeast Asia, and the
cannabis-producing states in the Horn of
Africa. They favored weak controls because existing
restrictions on production and export had directly affected large
segments of their domestic population and industry. They supported
national control efforts based on local conditions and were wary of
strong international control bodies under the UN. Although
essentially powerless to fight the prohibition philosophy directly, they
effectively forced a compromise by working together to dilute the
treaty language with exceptions, loopholes and deferrals. They also
sought development aid to compensate for losses caused by strict
controls.
- Manufacturing states group:
This group included primarily Western industrialized nations, the
key players being the United States
, the United Kingdom
, Canada
, Switzerland
, the Netherlands
, West
Germany
, and Japan
.
Having no cultural affinity for organic drug use and being faced
with the effects that drug abuse was
having on their citizens, they advocated very stringent controls on
the production of organic raw materials and on illicit trafficking. As the principal
manufacturers of synthetic psychotropics, and backed by a
determined industry lobby, they forcefully opposed undue
restrictions on medical research or the production and distribution
of manufactured drugs. They favored strong supranational control
bodies as long as they continued to exercise de facto control over
such bodies. According to W.B. McAllister's Drug Diplomacy in
the Twentieth Century, their strategy was essentially to
"shift as much of the regulatory burden as possible to the
raw-material-producing states while retaining as much of their own
freedom as possible."
- Strict control group: These were essentially
non-producing and non-manufacturing states with no direct economic
stake in the drug trade. The key members were France
, Sweden
, Brazil
, and the
Republic of
China
. Most of the states in this group were
culturally opposed to drug use and suffered from abuse problems.
They favored restricting drug use to medical and scientific
purposes and were willing to sacrifice a degree of national
sovereignty to ensure the effectiveness
of supranational control bodies. They were forced to moderate their
demands in order to secure the widest possible agreement.
- Weak control group: This
group was led by the Soviet
Union
and often included its allies in Europe, Asia and Africa. They considered drug control a purely
internal issue and adamantly opposed any intrusion on national
sovereignty, such as independent inspections. With little interest
in the drug trade and minimal domestic abuse problems, they refused
to give any supranational body excessive power, especially over
internal decision-making.
- Neutral group: This was a
diverse group including most of the African
countries, Central America,
sub-Andean South America, Luxembourg
and the Vatican
. They
had no strong interest in the issue apart from ensuring their own
access to sufficient drug supplies. Some voted with political
blocs, others were willing to trade votes, and others were truly
neutral and could go either way on the control issue depending on
the persuasive power of the arguments presented. In general, they
supported compromise with a view to obtaining the broadest possible
agreement.
These competing interests, after more than eight weeks of
negotiations, finally produced a compromise treaty. Several
controls were watered down; for instance, the proposed mandatory
embargoes on nations failing to comply with
the treaty became recommendatory. The 1953 New York Opium Protocol,
which had not yet entered into force, limited opium production to
seven countries; the Single Convention lifted that restriction, but
instituted other regulations and put the
International Narcotics
Control Board in charge of monitoring their enforcement. A
compromise was also struck that allowed
heroin and some other drugs classified as
particularly dangerous to escape absolute prohibition.
The Single Convention created four Schedules of controlled
substances and a process for adding new substances to the Schedules
without amending the treaty. The Schedules were designed to have
significantly stricter regulations than the two drug "Groups"
established by predecessor treaties. For the first time,
cannabis was added to the list of internationally
controlled drugs. In fact, regulations on the cannabis plant – as
well as the
opium poppy,
the
coca bush, poppy straw and cannabis leaves
– were embedded in the text of the treaty, making it impossible to
deregulate them through the normal Scheduling process. A 1962 issue
of the
Commission on
Narcotic Drugs'
Bulletin
on Narcotics proudly announced that "after a definite
transitional period, all non-medical use of narcotic drugs, such as
opium smoking, opium eating, consumption of cannabis (hashish,
marijuana) and chewing of coca leaves, will be outlawed everywhere.
This is a goal which workers in international narcotics control all
over the world have striven to achieve for half a century."
An
August 3,
1962
Economic and Social Council resolution ordered the issuance of the
Commentary on the Single Convention on Narcotic Drugs. The legal
commentary was created by the
United Nations
Secretary-General's staff (specifically,
Adolf Lande, former Secretary of the Permanent
Central Narcotics Board and Drug Supervisory Body), operating under
a mandate to give "an interpretation of the provisions of the
Convention in the light of the relevant conference proceedings and
other material." The Commentary contains the Single Convention's
legislative history and is an
invaluable aid to interpreting the treaty.
Single Convention entered into force on December 13, 1964, having
met
Article 41's requirement of 40 ratifications. As of January 1,
2005, 180
states were Parties to the
treaty.
Others, such as Cambodia
, have committed to becoming Parties.
On
May 21,
1971, the
UN Economic and Social
Council called a conference of plenipotentiaries to consider
amendments to the Single Convention. The conference met at the
United Nations Office at Geneva from
March 6
to
March 24,
1972,
producing the 1972
Protocol
Amending the Single Convention on Narcotic Drugs. The
amendments entered into force on
August 8,
1975.
On
November 11, 1990,
mechanisms for enforcing the Single Convention were expanded
significantly by the entry into force of the
United Nations Convention Against Illicit Traffic in Narcotic Drugs
and Psychotropic Substances, which had been signed at Vienna
on December 20, 1988.
The
Preamble to this treaty acknowledges the inadequacy of the
Single Convention's controls to stop "steadily increasing inroads
into various social groups made by illicit traffic in narcotic
drugs and psychotropic substances". The new treaty focuses on
stopping
organized crime by
providing for international cooperation in apprehending and
convicting gangsters and starving them of funds through
forfeiture, asset freezing, and other
methods. It also establishes a system for placing precursors to
Scheduled drugs under international control.
Some non-Parties to
the Single Convention, such as Andorra
, belong to this treaty and thus are still under the
international drug control regime.
Medical and other drug uses
The Single Convention repeatedly affirms the importance of medical
use of controlled substances. The
Preamble
notes that "the medical use of
narcotic
drugs continues to be indispensable for the relief of pain and
suffering and that adequate provision must be made to ensure the
availability of narcotic drugs for such purposes". Articles 1, 2,
4, 9, 12, 19, and 49 contain provisions relating to "medical and
scientific" use of controlled substances. In almost all cases,
parties are permitted to allow dispensation and use of controlled
substances under a
prescription, subject to record-keeping
requirements and other restrictions.
The Single Convention unambiguously condemns
drug addiction, however, stating that
"addiction to narcotic drugs constitutes a serious evil for the
individual and is fraught with social and economic danger to
mankind". It takes a
prohibitionist approach to the problem
of drug addiction, attempting to stop all non-medical,
non-scientific use of narcotic drugs.
Article 4 requires nations to limit use and possession of drugs
to medicinal and scientific purposes.
Article 49 allows countries to phase out
coca leaf chewing,
opium smoking,
and other traditional drug uses gradually, but provides that "the
use of cannabis for other than medical and scientific purposes must
be discontinued as soon as possible."
The discontinuation of these prohibited uses is intended to be
achieved by cutting off supply. Rather than calling on nations to
prosecute drug users, the treaty focuses on traffickers and
producers. As of March 2005, 116 drugs were controlled under the
Single Convention.
Penal provisions
Article
36 requires Parties to criminalize "cultivation, production,
manufacture, extraction, preparation, possession, offering,
offering for sale, distribution, purchase, sale, delivery on any
terms whatsoever, brokerage, dispatch, dispatch in transit,
transport, importation and exportation of drugs contrary to the
provisions of this Convention," as well as "[i]ntentional
participation in, conspiracy to commit and attempts to commit, any
of such offences, and preparatory acts and financial operations in
connexion with the offences referred to in this article".
The Article also provides for
extradition of drug offenders, although a Party
has a right to refuse to extradite a suspect if "competent
authorities consider that the offense is not sufficiently serious."
A 1971 amendment to the Article grants nations the discretion to
substitute "treatment, education, after-care,
rehabilitation and social
reintegration" for criminal penalties if the offender is a drug
abuser. A
loophole in the Single Convention
is that it requires Parties to place anti-drug laws on the books,
but does not clearly mandate their enforcement, except in the case
of drug cultivation.
Drug enforcement varies widely between nations.
Many European countries, including the United Kingdom
, Germany
, and, most famously, the Netherlands
, do not prosecute all petty drug offenses.
Dutch
coffee shop are allowed to sell
small amounts of
cannabis to consumers.
However, the
Ministry of
Health, Welfare and Sport's report,
Drugs Policy in the
Netherlands, notes that large-scale "[p]roduction and
trafficking are dealt with severely under the criminal law, in
accordance with the UN Single Convention. Each year the Public
Prosecutions Department deals with an average of 10,000 cases
involving infringements of the Opium Act."
Some of the most
severe penalties for drug trafficking are handed down in certain
Asian countries, such as Malaysia
, which mandate capital punishment for offenses involving
amounts over a certain threshold. Singapore
mandates the death penalty for trafficking in 15 g
(half an ounce) of heroin, 30 g of cocaine or 500 g of
cannabis. Most nations, such as France
and the
United
States
, find a middle ground, imposing a spectrum of
sanctions ranging from probation to
life imprisonment for drug
offenses.
The Single Convention's penal provisions frequently begin with
clauses such as "Subject to its constitutional limitations, each
Party shall . . ." Thus, if a nation's
constitution prohibited instituting the
criminal penalties called for by the Single Convention, those
provisions would not be binding on that country. However, Professor
Cindy Fazey's
A Growing Market: The
Domestic Cultivation of Cannabis points out, "Whilst this
strategy may be practical politics for some countries, critics will
ask why it has taken almost half a century to discover that the UN
conventions conflict with a constitutional principle.
The argument is
particularly difficult to deploy for countries like Britain
, where constitutional principles are not formalized
or codified to any significant degree." However the current
move in Switzerland
to enshrine cannabis decriminalization in the
national constitution by popular initiative could profit from this
rule.
Possession for personal use

Different nations have drawn different
conclusions as to whether the treaty requires criminalization of
drug possession for personal use.
is unclear whether or not the treaty requires criminalization of
drug possession for personal use.
The treaty's language is ambiguous, and a
ruling by the International Court of
Justice
would probably be required to settle the matter
decisively. However, several commissions have attempted to
tackle the question. With the exception of the Le Dain Commission,
most have found that states are allowed to legalize possession for
personal use.
The Canadian
Le
Dain Commission of Inquiry into the Non-Medical Use of Drugs'
1972 report cites circumstantial evidence suggesting that states
must prohibit possession for personal use:
- It has generally been assumed that "possession" in
Article 36 includes possession for use as well as possession
for the purpose of trafficking. This is a reasonable
inference from the terms of
Article 4, which obliges the parties "to limit exclusively to
medical and scientific purposes the production, manufacture,
export, import, distribution of, trade in, use and possession of
drugs." There is also
Article 33, which provides that "The Parties shall not permit
the possession of drugs except under legal authority."
[...] On the face of
Article 26 it would not be unreasonable to argue that what is
contemplated is possession for the purpose of trafficking rather
than possession for use, and that the requirements of the article
are satisfied if the former kind of possession is made a penal
offense. The prevailing view, however, is that the word
"possession" in
Article 36 includes simple possession for use.
However, LeDain himself concludes
The costs to a significant number of individuals,
the majority of whom are young people, and to society generally, of
a policy of prohibition of simple possession are not justified by
the potential for harm of cannabis and the additional influence
which such a policy is likely to have upon perception of harm,
demand and availability. We, therefore, recommend the
repeal of the prohibition against the simple possession of
cannabis.
The Canadian Department of National Health and Welfare's 1979
report,
The Single Convention and Its Implications for Canadian
Cannabis Policy, counters with circumstantial evidence to the
contrary:
- The substantive argument in support of simple possession
falling outside the scope of
Article 36 is founded on the assumption that it is intended to
insure a penal response to the problem of illicit trafficking
rather than to punish drug users who do not participate in the
traffic. (See United Nations, 1973:112; Noll, 1977:44–45)
The Third Draft of the Single Convention, which served as the
working document for the 1961 Plenipotentiary Conference, contained
a paragraph identical to that which now appears as
Article 36, subparagraph 1(a). This paragraph was
included in a chapter entitled Measures Against Illicit
Traffickers, but the format by which the Third Draft was
divided into chapters was not transferred to the Single Convention,
and this, apparently, is the sole reason why this chapter heading,
along with all others, was deleted. (See United Nations,
1973:112)
Article 36 is still located in that part of the Convention
concerned with the illicit trade, sandwiched between
Article 35 (Action Against the Illicit Traffic) and
Article 37 (Seizure and Confiscation). In
addition, it should be noted that the word "use," suggesting
personal consumption rather than trafficking, appears in
conjunction with "possession" in
Article 4 (which pertains to non-penal "general obligations"),
but not in the penal provisions of
Article 36.
The Sackville Commission of South Australia concluded in 1978 that:
- . . . the Convention does not require
signatories to make either use or possession for personal use
punishable offenses ... This is because ‘use’ is not
specifically covered by Article 36 and the term ‘possession’ in
that Article and elsewhere can be read as confined to possession
for the purpose of dealing".
The American
National
Commission on Marihuana and Drug Abuse reached a similar
conclusion in 1972, finding "that the word 'possession' in
Article 36 refers not to possession for personal use but to
Possession as a link in illicit trafficking."
The Canadian Department of National Health and Welfare report cites
the Commentary itself in backing up its interpretation:
- The official Commentary on the Single Convention on
Narcotic Drugs 1961, as prepared by the office of the U.N.
Secretary-General, adopts a permissive interpretation of
possession in
Article 36. It notes that whether or not the
possession of drugs (including prohibited forms of cannabis) for
personal use requires the imposition of penal sanctions is a
question which may be answered differently in different
countries. Further, the Commentary notes that parties
which interpret Article 36 as requiring a punitive legal response
to simple possession, may undoubtedly choose not to provide for
imprisonment of persons found in such possession, but to impose
only minor penalties such as fines or even censure (since
possession of a small quantity of drugs for personal consumption
may be held not to be a serious offense under article 36... and
only a serious offense is liable to adequate punishment
particularly by imprisonment or other penalties of deprivation of
liberty.
The
Bulletin on Narcotics
attempted to tackle the question in 1977:
- Since some confusion and misunderstanding had existed in
the past and some instances still persist in respect of the legal
position laid down in the international treaties concerning the
relationship between penal sanctions and drug abuse, some
clarifying remarks are called for. These were already
offered at the XIth International Congress on Penal Law. 5
They were reiterated at the Fifth United Nations Congress on the
Prevention of Crime and the Treatment of Offenders. 6 The
international treaties in no way insist on harsh penal sanctions
with regard to drug abuse, as is sometimes alleged by persons
criticising the international drug control system; the treaties are
much more subtle and flexible than sometimes interpreted.
- First of all, Article 4 of the Single Convention contains
the general obligations for Parties to this Convention to "take
such legislative and administrative measures as may be necessary,
subject to the provisions of this Convention, to limit exclusively
to medical and scientific purposes the production, manufacture,
export, import, distribution of, trade in, use and possession of
drugs." From the contents of this provision it is clear
that use of drugs and their possession for personal consumption has
also to be limited by legislation and administrative measures
exclusively to medical and scientific purposes.
Consequently, "legalization" of drugs in the sense of making
them freely available for non-medical and non-scientific
purposes-as it is sometimes demanded by public mass media and even
experts in discussions on the subject-is without any doubt excluded
and unacceptable under the present international drug control
system as established by the international treaties. The
question, however, remains whether Parties are obliged by the
international treaties to apply penal sanctions for unauthorized
use and unauthorized possession of drugs for personal
consumption. It is on this point that confusion still
exists and clarification is needed.
- It is a fact that "use" (or "personal consumption") is not
enumerated amongst the punishable offences in accordance with
paragraph 1 of Article 36 of the Single Convention.
Although, as mentioned above, Parties are required to limit the
use of drugs exclusively to medical and scientific purposes, the
Single Convention does not require them to attain the goal by
providing penal sanctions for unauthorized "use" or "personal
consumption" of drugs.
- Unauthorized "possession" of drugs is mentioned in
paragraph 1 of Article 36, but from the context it is clear that,
as stated in the Official Commentary by the Secretary-General of
the United Nations, "possession" of drugs for personal
consumption is not to be considered a "punishable offence" by a
Party to the Single Convention. The whole international
drug control system envisages in its penal provisions
the illicit traffic in drugs; this also holds true for
the 1972 Protocol Amending the Single Convention and for the 1971
Convention on Psychotropic Substances. As there is no
obligation to provide penal sanctions for "use" in the sense of
personal consumption and "possession" of drugs for personal
consumption, any criticism levelled against the international drug
control system by protagonists in favour of the so-called
"liberalization" or decriminalization or "de-penalization" of use
and possession of drugs for personal consumption is quite beside
the point.
Schedules of drugs
The Single Convention's Schedules of drugs range from most
restrictive to least restrictive, in this order: Schedule IV,
Schedule I, Schedule II, Schedule III. The list of drugs initially
controlled was annexed to the treaty.
Article 3 states that in order for a drug to be placed in a
Schedule, the
World Health
Organization must make the findings required for that Schedule,
to wit:
- Schedule I – The substance is liable to
similar abuse and productive of similar ill effects as the drugs
already in Schedule I or Schedule II, or is convertible into a
drug.
- Schedule II – The substance is liable to
similar abuse and productive of similar ill effects as the drugs
already in Schedule I or Schedule II, or is convertible into a
drug.
- Schedule III – The preparation, because of the
substances which it contains, is not liable to abuse and cannot
produce ill effects; and the drug therein is not readily
recoverable.
- Schedule IV – The drug, which is already in
Schedule I, is particularly liable to abuse and to produce ill
effects, and such liability is not offset by substantial
therapeutic advantages.
Schedule I, according to the Commentary, is the
category of drugs whose control provisions "constitute the standard
regime under the Single Convention." The principal features of that
regime are:
- Limitation to medical and scientific purposes of all phases of
narcotics trade (manufacture, domestic trade, both wholesale and retail, and
international trade) in, and of
the possession and use of, drugs;
- Requirement of governmental authorization (licensing or state
ownership) of participation in any phase of the narcotics trade and
of a specific authorization (import and export authorization) of
each individual international transaction;
- Obligation of all participants in the narcotics trade to keep
detailed records of their transactions in drugs;
- Requirement of a medical
prescription for the supply or dispensation of drugs to
individuals;
- A system of limiting the quantities of drugs available, by
manufacture or import or both, in each country and territory, to
those needed for medical and scientific purposes.
Schedule II drugs are regulated only slightly less
strictly than Schedule I drugs. The Commentary confirms, "Drugs in
Schedule II are subject to the same measures of control as drugs in
Schedule I, with only a few exceptions":
- The drugs are not subject to the provisions of
Article 30, paragraphs 2 and 5, as regards the retail
trade.
- Governments are thus not bound to prevent the accumulation of
drugs in Schedule II in the possession of retail distributors, in
excess of the quantities required for the normal conduct of
business.
- Medical prescriptions for the supply or dispensation of these
drugs to individuals are not obligatory.
- Such drugs are also exempted from the provision – which in fact
is no more than a suggestion – concerning the use of official
prescription forms in the shape of counterfoil books issued by the
competent governmental authorities or by authorized professional
associations.
- Parties to the Single Convention need not require that the
label under which a drug in Schedule II is offered for sale in the
retail trade show the exact content by weight or percentage.
Schedule III "contains preparations which enjoy a
privileged position under the Single Convention, i.e. are subject
to a less strict regime than other Preparations," according to the
Commentary. Specifically:
- Government authorizations are not required for each import or
export of preparations in Schedule III. The import certificate and
export authorization system laid down in
Article 31, paragraphs 4 to 15, which governs the international
transactions in drugs and their preparations, does not apply to the
preparations in Schedule III.
- The only estimates and statistical returns that a Party need
furnish to the INCB in reference to Schedule III preparations are
estimates of the quantities of drugs to be utilized for the
compounding of preparations in Schedule III, and information on the
amounts of drugs actually so used.
Schedule IV is the category of drugs, such as
heroin, that are considered to have
"particularly dangerous properties" in comparison to other drugs
(
alcohol is left unregulated). According to
Article 2, "The drugs in Schedule IV shall also be included in
Schedule I and subject to all measures of control applicable to
drugs in the latter Schedule" as well as whatever "special measures
of control"; each Party deems necessary. This is in contrast to the
U.S. Controlled Substances Act, which has five Schedules ranging
from Schedule I (most restrictive) to Schedule V (least
restrictive), and the
Convention on Psychotropic
Substances, which has four Schedules ranging for Schedule I
(most restrictive) to Schedule IV (least restrictive).
Under certain circumstances, Parties are required to limit Schedule
IV drugs to research purposes only:
- (b) A Party shall, if in its opinion the prevailing
conditions in its country render it the most appropriate means of
protecting the public health and welfare, prohibit the production,
manufacture, export and import of, trade in, possession or use of
any such drug except for amounts which may be necessary for medical
and scientific research only, including clinical trials therewith
to be conducted under or subject to the direct supervision and
control of the Party.
The Commentary explains two situations in which this provision
would apply:
- For a considerable period of time - and still at the time
of writing - there has been no significant diversion of legally
manufactured drugs from legal trade into illicit channels; but if a
Government were unable to prevent such a diversion of drugs in
Schedule IV, a situation would arise in which the measures of
prohibition mentioned in subparagraph (b) would be "the most
appropriate means of protecting the public health and
welfare". Whether this was or was not the case would be
left to the judgement of the Party concerned whose bona fide
opinion on this matter could not be challenged by any other
Party.
- Another situation in which measures of prohibition would be
"appropriate" for the protection of public health and welfare might
exist where the members of the medical profession administered or
prescribed drugs in Schedule IV in an unduly extensive way, and
other less radical measures, such as warnings by public
authorities, professional associations or manufacturers, were
ineffective. It may however be assumed that such a
situation could rarely if ever arise.
The Commentary notes that "Whether the prohibition of drugs in
Schedule IV (
Cannabis and cannabis resin,
desomorphine,
heroin,
ketobemidone)
should be mandatory or only recommended was a controversial
question at the Plenipotentiary Conference." The provision adopted
represents "a compromise which leaves prohibition to the judgement,
though theoretically not to the discretion, of each Party." The
Parties are required to act in good faith in making this decision,
or else they will be in violation of the treaty.
Power structure
The Single Convention gives the
UN Economic and Social
Council's
Commission on
Narcotic Drugs (CND) power to add or delete drugs from the
Schedules, in accordance with the
World Health Organization's
findings and recommendations. Any Party to the treaty may request
an amendment to the Schedules, or request a review of the
Commission's decision. The Economic and Social Council is the only
body that has power to confirm, alter, or reverse the CND's
scheduling decisions. The
United Nations General
Assembly can approve or modify any CND decision, except for
scheduling decisions.
The CND's annual meeting serves as a forum for nations to debate
drug policy.
At the 2005 meeting, France
, Germany
, the Netherlands
, Canada
, Australia and Iran
rallied in
opposition to the UN's zero-tolerance approach in international
drug policy. Their appeal was vetoed by the United States
, while the United Kingdom
delegation remained reticent. Meanwhile,
U.S.
Office of National Drug
Control Policy Director John
Walters clashed with United
Nations Office on Drugs and Crime
Executive Director Antonio Maria Costa on the issue of
needle exchange programs.
Walters advocated strict prohibition, while Costa opined, "We must
not deny these addicts any genuine opportunities to remain
HIV-negative."
The
International
Narcotics Control Board (INCB) is mandated by
Article 9 of the Single Convention to "endeavour to limit the
cultivation, production, manufacture and use of drugs to an
adequate amount required for
medical and
scientific purposes, to ensure their
availability for such purposes and to prevent illicit cultivation,
production and manufacture of, and illicit trafficking in and use
of, drugs." The INCB administers the estimate system, which limits
each nation's annual production of controlled substances to the
estimated amounts needed for medical and scientific purposes.
Article 21 provides that "the total of the quantities of each
drug manufactured and imported by any country or territory in any
one year shall not exceed the sum of" the quantity:
- Consumed, within the limit of the relevant estimate, for
medical and scientific purposes;
- Used, within the limit of the relevant estimate, for the
manufacture of other drugs, of preparations in Schedule Ill, and of
substances not covered by this Convention;
- Exported;
- Added to the stock for the purpose of bringing that stock up to
the level specified in the relevant estimate; and
- Acquired within the limit of the relevant estimate for special
purposes.
Article 21 bis, added to the treaty by a 1971 amendment, gives
the INCB more enforcement power by allowing it to deduct from a
nation's production quota of
cannabis,
opium, and
coca the
amounts it determines have been produced within that nation and
introduced into the illicit traffic. This could happen as a result
of failing to control either illicit production or
diversion of licitly produced opium to illicit
purposes. In this way, the INCB can essentially punish a
narcotics-exporting nation that does not control its illicit
traffic by imposing an
economic
sanction on its medicinal narcotics industry.
The Single Convention exerts power even over those nations that
have not ratified it. The International Narcotics Board states:
- The fact that the system generally works well is mainly due
to the estimates system that covers all countries whether or not
parties to the Convention. Countries are under an
obligation not to exceed the amounts of the estimates confirmed or
established by the INCB.
Article
14 authorizes the INCB to recommend an
embargo on imports and exports of drugs from any
noncompliant nations. The INCB can also issue reports critical of
noncompliant nations, and forward those reports to all Parties.
This
happened when the United
Kingdom
reclassified cannabis from Class B to class C,
eliminating the threat of arrest for possession. See
Cannabis
reclassification in the United Kingdom.
The most controversial decisions of the INCB are those in which it
assumes the power to interpret the Single Convention.
Germany
, the Netherlands
, Switzerland
, and Spain
continue to
experiment with medically supervised injection rooms, despite the
INCB's objections that the Single Convention's allowance of
"scientific purposes" is limited to clinical trials of
pharmaceutical grade drugs and not public health
interventions. These European nations have more leverage to
disregard the Board's decisions because they are not dependent on
licit psychoactive drug exports (which are regulated by the Board).
As
international lawyer Bill Bush notes, "Because of the Tasmanian
opium poppy industry, Australia is more vulnerable to political pressure
than, say, Germany
."
The INCB is an outspoken opponent of drug legalization. Its 2002
report rejects a common argument for drug reform, stating, "Persons
in favour of legalizing illicit drug use argue that drug abusers
should not have their basic rights violated; however, it does not
seem to have occurred to those persons that drug abusers themselves
violate the basic rights of their own family members and society."
The report dismisses concerns that drug control conflicts with
principles of
limited government
and self-determination, arguing, "States have a moral and legal
responsibility to protect drug abusers from further
self-destruction." The report takes a
majoritarian view of the situation, declaring,
"Governments must respect the view of the majority of lawful
citizens; and those citizens are against illicit drug use."
Article 48 designates the International Court of
Justice
as the arbiter of disputes about the interpretation
or application of the Single Convention, if mediation, negotiation,
and other forms of alternative dispute
resolution fail.
Limitation of scope
The Single Convention allows only drugs with morphine-like,
cocaine-like, and cannabis-like effects to be added to the
Schedules. The strength of the drug is not relevant; only the
similarity of its effects to the substances already controlled. For
instance,
etorphine and
acetorphine were considered sufficiently
morphine-like to fall under the treaty's scope, although they are
many times more potent than morphine. However, according to the
Commentary:
- The Office of Legal Affairs of the United Nations ruled, in
an opinion given to the Commission on Narcotic Drugs at its
twenty-third session, that barbiturates,
tranquillizers and amphetamines were outside the scope of the
Single Convention. It pointed out that there was an
understanding at all stages of the drafting of the Single
Convention, in particular at the Plenipotentiary Conference of 1961
which adopted that treaty, that the Convention was not applicable
to these three types of substances, although the effects of
amphetamines have some degree of similarity to cocaine, and those
of barbiturates and tranquillizers to morphine.
Since cannabis is a
hallucinogen
(although some dispute this), the Commentary speculates that
mescaline,
psilocybin,
tetrahydrocannabinol, and
LSD could have been considered sufficiently
cannabis-like to be regulated under the Single Convention; however,
it opines, "It appears that the fact that the potent
hallucinogenics whose abuse has spread in recent years have not
been brought under international narcotics control does not result
from legal reasons, but rather from the view of Governments that a
regime different from that offered by the Single Convention would
be more adequate." That different regime was instituted by the 1971
Convention on
Psychotropic Substances. The Convention on Psychotropic Drugs'
scope can include any drug not already under international control
if the
World Health
Organization finds that:
- The substance has the capacity to produce "[a] state of
dependence" AND "[c]entral nervous system stimulation or
depression, resulting in hallucinations or disturbances in motor
function or thinking or behaviour or perception or mood"; or
- The substance has the capacity to produce similar abuse and
similar ill effects as LSD or one of the other
controlled substances enumerated in Convention; or
- There is sufficient evidence that the substance is being or is
likely to be abused so as to constitute a public health and social
problem warranting the placing of the substance under international
control.
The reason for sharply limiting the scope of Single Convention to a
few types of drugs while letting the Convention on Psychotropic
Drugs cover the rest was concern for the interests of industry.
Professor
Cindy Fazey's
The
Mechanics and Dynamics of the UN System for International Drug
Control explains, "It should be noted that concerted efforts
by drug manufacturing nations and the pharmaceutical industry
ensured that the controls on psychotropics in the 1971 treaty were
considerably looser than those applied to organic drugs in the
Single Convention."
A March
24, 2003 European
Parliament
committee report noted the disparity in how drugs
are regulated under the two treaties:
- The 1971 Convention, which closely resembles the Single
Convention, establishes an international control which is clearly
less rigorous for the so-called 'psychotropic' substances,
generally produced by the pharmaceutical industry. .
. The parallel existence of the Single Convention and
the 1971 Convention have led to certain illogical effects such as
the fact that a plant (cannabis) containing
at most 3% of a principal element is dealt with more severely than
the pure substance at 100% (tetrahydrocannabinol or THC).
For this
reason, the European
Parliament
, Transnational Radical Party, and
other organizations have proposed removing cannabis and other drugs
from the Single Convention and scheduling them under the Convention
on Psychotropic Substances.
Furthermore, the provisions of the Single Convention regarding the
national supply and demand of opium to make morphine contribute to
the global shortage of essential poppy-based pain relief medicines.
According to the Convention, governments can only request raw poppy
materials according to the amount of poppy-based medicines used in
the two preceding years. Consequently, in countries where
underprescription is chronic due to the high prices of morphine and
lack of availability and medical training in the prescription of
poppy-based drugs, it is impossible to demand enough raw poppy
materials from the INCB, as the Convention's regulating body, to
meet the country's pain relief needs. As such, 77% of the world's
poppy-based medicine supplies are used by only six countries (See:
Fischer, B J. Rehm, and T Culbert, “Opium based medicines: a
mapping of global supply, demand and needs” inSpivack D. (ed.)
Feasibility Study on Opium Licensing in Afghanistan, Kabul, 2005.
p.85–86. ). Many critics of the Convention cite this as one of its
primary limitations and the
World Health Organisation is
currently attempting to increase prescription of poppy-based drugs
and to help governments of emerging countries in particular alter
their internal regulations to be able to demand poppy-based
medicines according to the Convention's provisions (see the
WHO "Assuring Availability of Opioid Analgesics
for Palliative Care").
The Senlis
Council, a European drug policy thinktank, proposes creating a
second-tier supply system that would complement the existing system
without altering the balance of its relatively closed supply and
demand system. The Council, who support licensing poppy cultivation
in Afghanistan to create Afghan morphine, believe the opium supply
in this country could go a long way to easing the pain relief needs
of sufferers in emerging countries by producing a cheap poppy-based
medicine solution (see [The Senlis Council]: "Poppy for
Medicine."
Regulation of cannabis

Articles 23 and 28 of the Single
Convention on Narcotic Drugs require cannabis-producing nations to
have a government agency that controls cultivation.
Cultivation
The Single Convention places the same restrictions on
cannabis cultivation that it does on
opium cultivation.
Article 23 and
Article 28 require each Party to establish a government agency
to control cultivation. Cultivators must deliver their total crop
to the agency, which must purchase and take physical possession of
them within four months after the end of harvest. The agency then
has the exclusive right of "importing, exporting, wholesale trading
and maintaining stocks other than those held by
manufacturers."
In the
United
States
, the National Institute on Drug
Abuse fulfills that function. NIDA administers a
contract with the University of Mississippi
to grow a 1.5 acre (6,000 m²) crop of cannabis
every other year; that supply comprises the only licit source of
cannabis for medical and research purposes in the United
States. Similarly, in 2000, Prairie Plant Systems was awarded a
five-year contract to grow cannabis in the Flin Flon
mine for Health Canada, that nation's licit cannabis
cultivation authority.
Article 28 specifically excludes industrial
hemp from these regulations, stating, "This Convention
shall not apply to the cultivation of the cannabis plant
exclusively for industrial purposes (fibre and seed) or
horticultural purposes."
Hemp-growing countries include China
, Romania
, France
, Germany
, Netherlands
, England
, and Hungary
. Hemp cultivation is theoretically legal in
the United
States
, but tight Drug Enforcement
Administration restrictions would likely make it
unprofitable.
Rescheduling proposals
There is some controversy over whether cannabis is "particularly
liable to abuse and to produce ill effects" and whether that
"liability is not offset by substantial therapeutic advantages," as
required by Schedule IV criteria. In particular, the discovery of
the
cannabinoid receptor system
in the late 1980s revolutionized scientific understanding of
cannabis' effects, and much anecdotal evidence has come to light
about the drug's medical uses. The Canadian Senate committee's
report notes,
- At the U.S.’s insistence, cannabis
was placed under the heaviest control regime in the Convention,
Schedule IV. The argument for placing cannabis in this
category was that it was widely abused. The WHO later
found that cannabis could have medical applications after all, but
the structure was already in place and no international action has
since been taken to correct this anomaly.
The Commentary points out the theoretical possibility of removing
cannabis from Schedule IV:
- Those who question the particularly harmful character of
cannabis and cannabis resin may hold that the Technical Committee
of the Plenipotentiary Conference was under its own criteria not
justified in placing these drugs in Schedule IV; but the approval
of the Committee's action by the Plenipotentiary Conference places
this inclusion beyond any legal doubt. Should the results
of the intensive research which is at the time of this writing
being undertaken on the effects of these two drugs so warrant, they
could be deleted from Schedule IV, and these two drugs, as well as
extracts and tinctures of cannabis, could be transferred from
Schedule I to Schedule II.
Cindy Fazey, former Chief of Demand
Reduction for the
United Nations Drug
Control Programme, has pointed out that it would be nearly
impossible to loosen international cannabis regulations. Even if
the Commission on Narcotic Drugs removed cannabis from Schedule IV
of the Single Convention, prohibitions against the plant would
remain imbedded in
Article 28 and other parts of the treaty. Fazey cited amendment
of the Articles and state-by-state denunciation as two theoretical
possibilities for changing cannabis' international legal status,
while pointing out that both face substantial barriers.
See
Cannabis
reform at the international level.
In a 2002 interview, INCB President
Philip O. Emafo condemned European cannabis
decriminalization measures:
- It is possible that the cannabis being used in Europe may not be the same species that is used in
developing countries and that is
causing untold health hazards to the young people who are finding
themselves in hospitals for treatment. Therefore, the
INCB's concern is that cannabis use should be restricted to medical
and scientific purposes, if there are any. Countries who
are party to the Single Convention need to respect the provisions
of the conventions and restrict the use of drugs listed in
Schedules I to IV to strictly medical and scientific
purposes.
However,
the European
Parliament
's Committee on Citizens' Freedoms and Rights,
Justice and Home Affairs issued a report on March 24, 2003
criticizing the Single Convention's scheduling regime:
- These schedules show that the main criterion for the
classification of a substance is its medical use. In view
of the principle according to which the only licit uses is those
for medical or scientific purposes (art. 4), plants or
substances deprived of this purpose are automatically considered as
particularly dangerous. Such is the case for cannabis and cannabis resin which are classified
with heroin in group IV for the sole reason
that they lack therapeutic value. A reason which is in any
event disputable, since cannabis could have numerous medical
uses.
There have been several lawsuits over whether cannabis' Schedule IV
status under the Single Convention requires total
prohibition at the national level. In
1970, the U.S. Congress enacted the
Controlled Substances Act to
implement the UN treaty, placing marijuana into Schedule I on the
advice of
Assistant
Secretary of Health Roger O.
Egeberg. His letter to
Harley O. Staggers, Chairman of the House
Committee on Interstate and Foreign Commerce, indicates that the
classification was intended to be provisional Text originally
presented at the 12
th International Conference on Drug
Policy Reform.:
- Some question has been raised whether the use of the plant
itself produces "severe psychological or physical dependence" as
required by a schedule I or even schedule II criterion.
Since there is still a considerable void in our knowledge of
the plant and effects of the active drug contained in it, our
recommendation is that marijuana be retained within schedule I at
least until the completion of certain studies now underway to
resolve the issue."
The reference to "certain studies" is to the then-forthcoming
National
Commission on Marijuana and Drug Abuse. In 1972, the Commission
released a report favoring decriminalization of marijuana. The
Richard Nixon administration took no
action to implement the recommendation, however. In 1972, the
National
Organization for the Reform of Marijuana Laws filed a
rescheduling petition under provisions of the Act. The government
declined to initiate proceedings on the basis of their
interpretation of U.S. treaty commitments. A federal Court ruled
against the government and ordered them to process the petition
(
NORML v. Ingersoll 497 F.2d 654 (1974)). The
government continued to rely on treaty commitments in their
interpretation of scheduling related issues concerning the NORML
petition, leading to another lawsuit (
NORML v. DEA 559
F.2d 735 (1977)). In this decision, the Court made clear that
the Act requires a full scientific and medical evaluation and the
fulfillment of the rescheduling process before treaty commitments
can be evaluated.
See
Removal of cannabis from Schedule I of the Controlled Substances
Act.
Cannabis leaves (as opposed to buds) are a special case. The
Canadian Health Protection Branch's
Cannabis Control Policy: A
Discussion Paper found that, while the Single Convention
requires nations to take measures against the misuse of, and
illicit traffic in, cannabis buds, a ban is not required on licit
production, distribution, and use of the leaves.
- The Single Convention defines "cannabis" as the flowering
or fruiting tops of the cannabis plant (excluding the seeds and
leaves when not accompanied by the tops) from which the resin has
not been extracted. (Art. 1, s-para.
1(b)) It is generally accepted that this definition permits the
legalization of the leaves of the cannabis plant, provided that
they are not accompanied by the flowering or fruiting tops.
However, uncertainty arises by virtue of paragraph 3 of Article
28 which requires parties to the Convention to "adopt such measures
as may be necessary to prevent the misuse of, and illicit traffic
in, the leaves of the cannabis plant." In summary, it
appears that parties are not obliged to prohibit the production,
distribution and use of the leaves (since they are not drugs, as
defined the Convention), although they must take necessary,
although unspecified, measures to prevent their misuse and
diversion to the illicit trade.
