-like effects. During the 1960s, such drugs became widely available, and government authorities opposed this for numerous reasons, arguing that along with negative health effects, drug use led to lowered moral standards. The Convention, which contains import and export restrictions and other rules aimed at limiting drug use to scientific and medical purposes, came into force on 16 August 1976. As of 2013, 183 member states are Parties to the treaty. The treaty is not self-implementing; individual countries must pass domestic laws to enact punishments and restrictions. Though not all scheduled substances are restricted in all signatory countries, many laws have been passed to implement or exceed the requirements of the Convention, including the Canadian Controlled Drugs and Substances Act, the UK Misuse of Drugs Act 1971 and the U.S. Psychotropic Substances Act. Adolf Lande, under the direction of the United Nations Office of Legal Affairs, prepared the Commentary on the Convention on Psychotropic Substances. The Commentary, published in 1976, is an aid to interpreting the treaty and constitutes a key part of its legislative history. Provisions to end the international trafficking of drugs covered by this Convention are contained in the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. This treaty, signed in 1988, regulates precursor chemicals to drugs controlled by the Single Convention and the Convention on Psychotropic Substances. It also strengthens provisions against

History

International drug control began with the 1912 International Opium Convention, a treaty which adopted import and export restrictions on the opium poppy's psychoactive derivatives. Over the next half-century, several additional treaties were adopted under
League of Nations The League of Nations (LN or LoN; , SdN) was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded on 10 January 1920 by the Paris Peace Conference (1919–1920), Paris Peace ...

and other drugs and granting the Permanent Central Opium Board power to monitor compliance. After the United Nations was formed in 1945, those enforcement functions passed to the UN. In 1961, a conference of plenipotentiaries in New York adopted the Single Convention on Narcotic Drugs, which consolidated the existing drug control treaties into one document and added cannabis to the list of prohibited plants. In order to appease the pharmaceutical interests, the Single Convention's scope was sharply limited to the list of drugs enumerated in the Schedules annexed to the treaty and to those drugs determined to have similar effects. During the 1960s, drug use increased in Western developed nations. Young people began using hallucinogenic, stimulant, and other drugs on a widespread scale that has continued to the present. In many jurisdictions, police had no laws under which to prosecute users and traffickers of these new drugs; LSD, for instance, was not prohibited federally in the U.S. until 1967. In 1968, " eply concerned at reports of serious damage to health being caused by LSD and similar hallucinogenic substances", the United Nations Economic and Social Council (ECOSOC) passed a resolution calling on nations to limit the use of such drugs to scientific and medical purposes and to impose import and export restrictions. Later that year, the UN General Assembly requested that ECOSOC call upon its Commission on Narcotic Drugs to "give urgent attention to the problem of the abuse of the psychotropic substances not yet under international control, including the possibility of placing such substances under international control". Circa 1969, with use of
stimulant Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, ...
s growing, ECOSOC noted with considerable consternation that the Commission "was unable to reach agreement on the applicability of the Single Convention on Narcotic Drugs, 1961 to these substances". The language of the Single Convention and its legislative history precluded any interpretation that would allow international regulation of these drugs under that treaty. A new convention, with a broader scope, would be required in order to bring those substances under control. Using the Single Convention as a template, the Commission prepared a draft convention which was forwarded to all UN member states. The

scheduled a conference for early 1971 to finalize the treaty. Meanwhile, countries had already begun passing legislation to implement the draft treaty. In 1969, Canada added Part IV to its Food and Drugs Act, placing a set of "restricted substances", including LSD, DMT, and MDA, under federal control. In 1970, the United States completely revamped its existing drug control laws by enacting the Controlled Substances Act (amended in 1978 by the Psychotropic Substances Act, which allows the U.S. drug control Schedules to be updated as needed to comply with the Convention). In 1971, the United Kingdom passed the Misuse of Drugs Act 1971. A host of other nations followed suit. A common feature shared by most implementing legislation is the establishment of several classes or Schedules of controlled substances, similarly to the Single Convention and the Convention on Psychotropic Substances, so that compliance with international law can be assured simply by placing a drug into the appropriate Schedule. The conference convened on 11 January 1971. Nations split into two rival factions, based on their interests. According to a

fought for tough regulations on synthetic drugs. The synthetic drug-producing states opposed those restrictions. Ultimately, the developing states' lobbying power was no match for the powerful pharmaceutical industry's, and the international regulations that emerged at the conference's close on 21 February were considerably weaker than those of the Single Convention. The Convention's adoption marked a major milestone in the development of the global drug control regime. Over 59 years, the system had evolved from a set of loose controls focused on a single drug into a comprehensive regulatory framework capable of encompassing almost any mind-altering substance imaginable. According to Rufus King, "It covers such a grab-bag of natural and manufactured items that at every stage of its consideration its proponents felt obliged to stress anew that it would not affect alcohol or tobacco abuse."

Schedules of Controlled Substances

The list of Schedules and the substances presently therein can be found on the International Narcotics Control Board's website. The Convention has four Schedules of controlled substances, ranging from Schedule I (most restrictive) to Schedule IV (least restrictive). A list of psychotropic substances, and their corresponding Schedules, was annexed to the 1971 treaty. The text of the Convention does not contain a formal description of the features of the substances fitting in each Schedule, in contrast to the US Controlled Substances Act of 1970, which gave specific criteria for each Schedule in the US system. The amphetamine-type stimulants (ATS), a legal class of stimulants – not all of which are substituted amphetamines – were defined in the 1971 treaty and in subsequent revisions. A 2002 European Parliament report and a 1996 UNODC report on ATS describe the international Schedules as listed below. * Schedule I includes drugs claimed to create a serious risk to public health, whose therapeutic value is not currently acknowledged by the Commission on Narcotic Drugs. It includes isomers of THC, synthetic psychedelics such as LSD, and natural psychedelics like certain substituted tryptamines. ATS such as cathinone, MDA, and MDMA (ecstasy) also fall under this category. * Schedule II includes certain ATS with therapeutic uses, such as delta-9-THC (including dronabinol, its synthetic form),

s (except flunitrazepam), and some weaker stimulants (such as modafinil and armodafinil). Over a dozen ATS are included in this category, including the substituted amphetamine phentermine. A 1999 UNODC report notes that Schedule I is a completely different regime from the other three. According to that report, Schedule I mostly contains hallucinogenic drugs such as LSD that are produced by illicit laboratories, while the other three Schedules are mainly for licitly produced pharmaceuticals. The UNODC report also claims that the Convention's Schedule I controls are stricter than those provided for under the Single Convention, a contention that seems to be contradicted by the 2002

reports. Although estimates and other controls specified by the Single Convention are not present in the Convention on Psychotropic Substances, the International Narcotics Control Board corrected the omission by asking Parties to submit information and statistics not required by the Convention, and using the initial positive responses from various organic drug producing states to convince others to follow. In addition, the Convention does impose tighter restrictions on imports and exports of Schedule I substances. A 1970 Bulletin on Narcotics report notes:


Scheduling process

Article 2 sets out a process for adding additional drugs to the Schedules. First, the
World Health Organization The World Health Organization (WHO) is a list of specialized agencies of the United Nations, specialized agency of the United Nations which coordinates responses to international public health issues and emergencies. It is headquartered in Gen ...
(WHO) must find that the drug meets the specific criteria set forth in Article 2, Section 4, and thus is eligible for control. Then, the WHO issues an assessment of the substance that includes: * The extent or likelihood of abuse, * The degree of gravity in the public health and social problem, * The degree of utility of the substance in legitimate medical therapy, and * Whether international control measures as provided in the treaty would be appropriate and useful. Article 2, Paragraph 4:
''If the World Health Organization finds: (a) That the substance has the capacity to produce (i) (1) A state of dependence, and (2) Central nervous system stimulation or depression, resulting in hallucinations or disturbances in motor function or thinking or behaviour or perception or mood, or (ii) Similar abuse and similar ill effects as a substance in Schedule I, II, III or IV, and (b) That 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 World Health Organization shall communicate to the Commission an assessment of the substance, including the extent or likelihood of abuse, the degree of seriousness of the public health and social problem and the degree of usefulness of the substance in medical therapy, together with recommendations on control measures, if any, that would be appropriate in the light of its assessment.''
The ''Commentary'' gives alcohol and tobacco as examples of psychoactive drugs that were deemed to not fit the above criteria by the 1971 Conference which negotiated the Convention. Alcohol can cause dependence and central nervous depression resulting in disturbances of thinking and behavior, furthermore alcohol causes similar effects as barbiturates, alcohol causes very serious "public health and social problems" in many countries, and also alcohol has minimal use in modern medicine. Nevertheless, according to the ''Commentary'': : ''Alcohol does not 'warrant' that type of control because it is not 'suitable' for the regime of the Vienna Convention. It appears obvious that the application of the administrative measures for which that treaty provides would not solve or alleviate the alcohol problem.'' Similarly, tobacco can cause dependence and has little medical use, but it was not considered to be a stimulant or depressant or to be similar to other scheduled substances. Most important, according to the ''Commentary'': : '' obaccois not suitable for the kinds of controls for which the Vienna Convention provides, and which if applied would not make any useful impact on the tobacco problem. That problem, however serious, therefore does not 'warrant' the placing of tobacco 'under international' control, i.e. under the Vienna Convention.'' The Commission on Narcotic Drugs makes the final decision on whether to add the drug to a Schedule, "taking into account the communication from the World Health Organization, whose assessments shall be determinative as to medical and scientific matters, and bearing in mind the economic, social, legal, administrative and other factors it may consider relevant". A similar process is followed in deleting a drug from the Schedules or transferring a drug between Schedules. For instance, at its 33rd meeting, the WHO Expert Committee on Drug Dependence recommended transferring tetrahydrocannabinol to Schedule IV of the Convention, citing its medical uses and low abuse potential. However, the Commission on Narcotic Drugs has declined to vote on whether to follow the WHO recommendation and reschedule tetrahydrocannabinol. The UN Economic and Social Council, as a parent body of the Commission on Narcotic Drugs, can alter or reverse the Commission's scheduling decisions. In the event of a disagreement about a drug's Scheduling, Article 2, Paragraph 7 allows a Party to, within 180 days of the communication of the Commission's decision, give the UN Secretary-General "a written notice that, in view of exceptional circumstances, it is not in a position to give effect with respect to that substance to all of the provisions of the Convention applicable to substances in that Schedule." This allows the nation to comply with a less stringent set of restrictions. The U.S. Controlled Substances Act's ''21 U.S.C. § 811(d)(4)'' implies that placing a drug in Schedule IV or V of the Act is sufficient to "carry out the minimum United States obligations under paragraph 7 of article 2 of the Convention". This provision, which calls for temporarily placing a drug under federal drug control in the event the Convention requires it, was invoked in 1984 with Rohypnol ( flunitrazepam). Long before abuse of the drug was sufficiently widespread in the United States to meet the Act's drug control criteria, rohypnol was added to the Schedules of the Convention on Psychotropic Substances, and the U.S. government had to place rohypnol in Schedule IV of the Controlled Substances Act in order to meet its minimum treaty obligations. As of March 2005, 111 substances were controlled under the Convention.

Ketamine

at its thirty-third meeting, noting, "Its use in veterinary medicine must also be considered in relation to its control". Ketamine remains uncontrolled internationally, although many nations (e.g. US and UK) have enacted restrictions on the drug.


MDMA

The Expert Committee's evaluation of MDMA during its 22nd meeting in 1985 was marked by pleas from physicians to allow further research into the drug's therapeutic uses. Paul Grof, chairman of the Expert Committee, argued that international control was not yet warranted, and that scheduling should be delayed pending completion of more studies. The Expert Committee concluded that because there was "insufficient evidence to indicate that the substance has therapeutic usefulness," it should be placed in Schedule I. However, its report did recommend more MDMA research: :''the Expert Committee held extensive discussions concerning therapeutic usefulness of 3,4 Methylenedioxymethamphetamine. While the Expert Committee found the reports intriguing, it felt that the studies lacked the appropriate methodological design necessary to ascertain the reliability of the observations. There was, however, sufficient interest expressed to recommend that investigations be encouraged to follow up these preliminary findings. To that end, the Expert Committee urged countries to use the provisions of Article 7 of the Convention on Psychotropic Substances to facilitate research on this interesting substance.'' MDMA was added to the convention as a Schedule I controlled substance in February 1986.


MBDB

MBDB (Methylbenzodioxolylbutanamine) is an entactogen with similar effects to MDMA. The thirty-second meeting of the WHO Expert Committee on Drug Dependence (September 2000) evaluated MBDB and recommended against scheduling.WHO Expert Committee on Drug Dependence
Thirty-second Report
, Technical Report Series 903 (2001)
From the WHO Expert Committee assessment of MBDB: :''Although MBDB is both structurally and pharmacologically similar to MDMA, the limited available data indicate that its stimulant and euphoriant effects are less pronounced than those of MDMA. There have been no reports of adverse or toxic effects of MBDB in humans. Law enforcement data on illicit trafficking of MBDB in Europe suggest that its availability and abuse may now be declining after reaching a peak during the latter half of the 1990s. For these reasons, the Committee did not consider the abuse liability of MBDB would constitute a significant risk to public health, thereby warranting its placement under international control. Scheduling of MBDB was therefore not recommended.''


Methcathinone

Circa 1994, the United States government notified the UN Secretary General that it supported controlling methcathinone, an addictive stimulant manufactured with common household products, as a Schedule I drug under the Convention. The FDA report warned of the drug's dangers, even noting that addicts in Russia were observed to often have " potassium permanganate burns on their fingers" and to "tend not to pay attention to their appearance, thus looking ragged with dirty hands and hair". With methcathinone having no medical use, the decision to place the drug in Schedule I was uncontested.


Nicotine

Traditionally, the UN has been reluctant to control nicotine and other drugs traditionally legal in Europe and North America, citing tolerance of a wide range of lifestyles. This contrasts with the regulatory regime for other highly addictive drugs. Gabriel G. Nahas, in a Bulletin on Narcotics report, noted: :''Some psychotropic substances such as nicotine, myristicin, ephedrine, mitraginyne, salvinorin A, arecoline, theophylline, theobromine, kava, khat, tobacco, L-theanine, or caffeine (in moderate amounts) or in moderate and responsible consumption, or alcoholic drinks (in small amounts or limited consumption) do not produce any measurable symptoms of neuropsychological toxicity, main physical damage, acute physical damage or main physical dependence or addiction, as also acute side effects or several adverse effects. Some pharmacologists have associated the symptoms of neuropsychological toxicity with behavioural toxicity or the toxic and addictive personality, the toxicity of drugs generally and overall depends by several factors as, environmental factors, economic factors, the field of the drug use, the place, the date, the time and social, psychological, emotional, mental, spiritual and intellectual factors that if are weak can to contribute as a risk factor or a risk behaviour. which include in addition: suppression of normal anxiety, toxic emotions, toxic relationships, toxic behavior, negative thinkings, reduction in motivation and non-purposive or inappropriate behaviour, illegal offense or immoral act necessary. However, the latter behavioural symptoms do not present "markers" which may be measurable in societies accepting as "normal" a wide range of life styles.'' Nonetheless, in October 1996, the Expert Committee considered controlling nicotine, especially products such as gum, patches, nasal spray, and inhalers. The UN ultimately left nicotine unregulated. Since then, nicotine products have become even more loosely controlled; Nicorette gum, for instance, is now an over-the-counter drug in the United States and in Finland, readily available in Finland from grocery stores and pharmacies. Another nicotine gum sold in Finland is called Nicotinell. All kinds of nicotine products are readily available in Finnish grocery stores and pharmacies.


Tetrahydrocannabinol

Tetrahydrocannabinol (THC), the main active ingredient in cannabis, was originally placed in Schedule I when the Convention was enacted in 1971. At its twenty-sixth meeting, in response to a 1987 request from the Government of the United States that THC be transferred from Schedule I to Schedule II, the WHO Expert Committee on Drug Dependence recommended that THC be transferred to Schedule II, citing its low abuse potential and "moderate to high therapeutic usefulness" in relieving nausea in chemotherapy patients. The Commission on Narcotic Drugs rejected the proposal. However, at its twenty-seventh meeting, the WHO Expert Committee again recommended that THC be moved to Schedule II. At its 45th meeting, on 29 April 1991, the Commission on Narcotic Drugs approved the transfer of dronabinol and its stereochemical variants from Schedule I to Schedule II of the Convention, while leaving other tetrahydrocannabinols and their stereochemical variants in Schedule I. At its thirty-third meeting (September 2002), the WHO Committee issued another evaluation of the drug and recommended that THC be moved to Schedule IV, stating: :''The abuse liability of dronabinol (delta-9-tetrahydrocannabinol) is expected to remain very low so long as cannabis continues to be readily available. The Committee considered that the abuse liability of dronabinol does not constitute a substantial risk to public health and society. In accordance with the established scheduling criteria, the Committee considered that dronabinol should be rescheduled to schedule IV of the 1971 Convention on Psychotropic Substances.'' No action was taken on this recommendation. And at its thirty-fourth meeting the WHO Committee recommended that THC be moved instead to Schedule III. In 2007 the Commission on Narcotic Drugs decided not to vote on whether to reschedule THC, and they requested that the WHO make another review when more information is available. In 2019, the WHO Expert Committee recommended that all isomers of THC be withdrawn from the Schedules of the 1971 Convention and included in the 1961 Convention alongside other Cannabis-related products and pharmaceutical preparations. However, this was rejected by a vote at the United Nations Commission on Narcotic Drugs on 2 December 2020.


2C-B (4-Bromo-2,5-dimethoxyphenethylamine)

2C-B is a psychedelic phenethylamine. At its thirty-second (September 2000) meeting the WHO Expert Committee on Drug Dependence recommended that 2C-B be placed in Schedule II, rather than with other scheduled psychedelics in Schedule I. The committee stated that " e altered state of mind induced by hallucinogens such as 2C-B may result in harm to the user and to others", but did not cite any evidence. From the WHO Expert Committee assessment of 2C-B: :''At high doses it is a strong hallucinogen, producing particularly marked visual hallucinations with an intense colour play, intriguing patterns emerging on surfaces and distortions of objects and faces. 2C-B is also reported to enhance sexual feelings, perception and performance.... Apart from its controversial experimental use in
psychotherapy Psychotherapy (also psychological therapy, talk therapy, or talking therapy) is the use of Psychology, psychological methods, particularly when based on regular Conversation, personal interaction, to help a person change behavior, increase hap ...
, 2C-B, like most other hallucinogens, does not have any known therapeutic usefulness.... The Committee noted, however, that hallucinogens are rarely associated with compulsive use and that abuse of 2C-B has been infrequent, suggesting that the drug is likely to constitute a substantial, rather than an especially serious, risk to public health. For these reasons, the Committee recommended that 2C-B be placed in Schedule II of the 1971 Convention.''


Medical and scientific uses

Like the Single Convention on narcotic medicines, the Convention on Psychotropic Substances recognizes scientific and medical use of psychoactive drugs, while banning other uses. Article 7 provides that, : ''In respect of substances in Schedule I, the Parties shall: (a) Prohibit all use except for scientific and very limited medical purposes by duly authorized persons, in medical or scientific establishments which are directly under the control of their Governments or specifically approved by them.'' In this sense, the U.S. Controlled Substances Act is stricter than the Convention requires. Both have a tightly restricted category of drugs called Schedule I, but the US Act restricts medical use of Schedule I substances to research studies, while the Convention allows broader, but limited and restricted, medical use of Schedule I controlled substances but scientific or industrial use of controlled substances is normally permitted.


Psychedelic plants and fungi

Several of the substances originally placed in Schedule I are psychedelic drugs which are contained in natural plants and fungi (such as peyote and psilocybin mushrooms) and which have long been used in religious or healing rituals. The Commentary notes the "Mexican Indian Tribes Mazatecas, Huicholes and Tarahumaras" as well as the " Kariri and Pankararu of eastern Brazil" as examples of societies that use such plants. Article 32, paragraph 4 allows for States, at the time of signature, ratification or accession, to make a reservation noting an exemption for : ''plants growing wild which contain psychotropic substances from among those in Schedule I and which are traditionally used by certain small, clearly determined groups in magical or religious rites''. However, the official ''Commentary on the Convention on Psychotropic Substances'' makes it clear that psychedelic plants (and indeed any plants) were not included in the original Schedules and are not covered or included at all by the Convention. This includes "infusion of the roots" of '' Mimosa tenuiflora'' (M. hostilis; which contains DMT) and "beverages" made from psilocybin mushrooms or psychotropic acacias, the latter of which are used in the DMT-containing beverage known colloquially as Ayahuasca. The purpose of Paragraph 4 of Article 32 was to allow States to "make a reservation assuring them the right to permit the continuation of the traditional use in question" in the case that plants were in the future added to the Schedule I. Currently, naught plants or plant products are included in the Schedules of the 1971 Convention. : ''Commentary 32-12: It may be pointed out that at the time of this writing the continued toleration of the use of hallucinogenic substances which the 1971 Conference had in mind would not require a reservation under paragraph 4. Schedule I does not list any of the natural hallucinogenic materials in question, but only chemical substances which constitute the active principles contained in them. The inclusion in Schedule I of the active principle of a substance does not mean that the substance itself is also included therein if it is a substance clearly distinct from the substance constituting its active principle. This view is in accordance with the traditional understanding of that question in the field of international drug control. Neither the crown (fruit, mescal button) of the Peyote cactus nor the roots of the plant Mimosa hostilis, Peganum Harmala that contains Harmala alkaloids or Syrian Rue, or Hawaiian Baby Woodrose plant and morning glory flowers that contains LSA or Lysergic Acid Amide or the Chacruna, a psychotropic shrub or plant which is used for make the Ayahuasca brew, ootnote: "An infusion of the roots is used"nor Psilocybe mushrooms ootnote: "Beverages made from such mushrooms are used"themselves are included in Schedule I, but only their respective active principles, mescaline, DMT and psilocybine (psilocine, psilotsin).'' : ''Commentary 32-13: It can however not be excluded that the fruit of the Peyote cactus, the roots of Mimosa hostilis, Psilocybe mushrooms or other hallucinogenic plant parts used in traditional magical or religious rites will in the future be placed in Schedule I by the operation of article 2, at a time at which the State concerned, having already deposited its instrument of ratification or accession, could no longer make the required reservation. It is submitted that Parties may under paragraph 4 make a reservation assuring them the right to permit the continuation of the traditional use in question in the case of such future actions by the Commission.'' Furthermore, in a letter, dated 13 September 2001, to the Dutch Ministry of Health, Herbert Schaepe, Secretary of the UN International Narcotics Control Board, clarified that the UN Conventions do not cover "preparations" of psilocybin mushrooms:
As you are aware, mushrooms containing the above substances are collected and abused for their hallucinogenic effects. As a matter of international law, no plants (natural material) containing psilocine and psilocybin are at present controlled under the Convention on Psychotropic Substances of 1971. Consequently, preparations made of these plants are not under international control and, therefore, not subject of the articles of the 1971 Convention. However, criminal cases are decided with reference to domestic law, which may otherwise provide for controls over mushrooms containing psilocine and psilocybin. As the Board can only speak as to the contours of the international drug conventions, I am unable to provide an opinion on the litigation in question.
Nonetheless, in 2001 the U.S. Government, in '' Gonzales v. O Centro Espirita Beneficente Uniao do Vegetal'', argued that ayahuasca, an infusion of Mimosa hostilis and other psychoactive plants that is used in religious rituals, was prohibited in the US because of the 1971 Convention. That case involved a seizure by U.S. Customs and Border Protection of several drums of DMT-containing liquid. Plaintiffs sued to have the drugs returned to them, claiming that they used it as a central part of their religion. In the discussions on Article 32, paragraph 4, noted in the Official Record of the 1971 Conference, the representative from the United States supported the explicit exemption of sacred psychoactive substances, stating: "Substances used for religious services should be placed under national rather than international control", while the representative of the
Holy See The Holy See (, ; ), also called the See of Rome, the Petrine See or the Apostolic See, is the central governing body of the Catholic Church and Vatican City. It encompasses the office of the pope as the Bishops in the Catholic Church, bishop ...
observed: "If exemptions were made in favour of certain ethnic groups, there would be nothing to prevent certain organizations of hippies from trying to make out, on religious grounds, that their consumption of psychotropic substances was permissible."


Organic plants

The Commentary on the Convention on Psychotropic Substances notes that while many plant-derived chemicals are controlled by the treaty, the plants themselves are not: :''The term "synthetic" appears to refer to a psychotropic substance manufactured by a process of full chemical synthesis. One may also assume that the authors of the Vienna Convention intended to apply the term "natural material" to parts of a plant which constitute a psychotropic substance, and the term "natural psychotropic substance" to a substance obtained directly from a plant by some process of manufacturing which was relatively simple, and in any event much simpler than a process of full chemical synthesis.'' :''(...)'' :''Cultivation of plants for the purpose of obtaining psychotropic substances or raw materials for the manufacture of such substances is not "manufacture" in the sense of Article 1, paragraph (i). Many provisions of the Vienna Convention governing psychotropic substances would be unsuitable for application to cultivation. The harvesting of psychotropic substances, i.e. separation of such substances from the plants from which they are obtained, is "manufacture".'' :''(...)'' :''The cultivation of plants from which psychotropic substances are obtained is not controlled by the Vienna Convention. (...) Neither the crown (fruit, mescal button) of the Peyote cactus nor the roots of the plant Mimosa hostilis nor Psilocybe mushrooms themselves are included in Schedule 1, but only their respective principles,

, in particular, argued that "production" of psychotropic drugs should not apply to wild-growing plants such as peyote cacti or psilocybin mushrooms. The Bulletin on Narcotics noted that "Mexico could not undertake to eradicate or destroy these plants". Compared to the Single Convention on Narcotic Drugs (which calls for "uprooting of all coca bushes which grow wild" and governmental licensing, purchasing, and wholesaling of licit opium, coca, and cannabis crops), the Convention on Psychotropic Substances devotes few words to the subject of psychoactive plants. On 2 July 1987, the United States Assistant Secretary of Health recommended that the

initiate scheduling action under the Controlled Substances Act in order to implement restrictions required by cathinone's Schedule I status under the Convention. The 1993 DEA rule placing cathinone in the CSA's Schedule I noted that it was effectively also banning khat: :''Cathinone is the major psychoactive component of the plant Catha edulis (khat). The young leaves of khat are chewed for a stimulant effect. Enactment of this rule results in the placement of any material which contains cathinone into Schedule I.''


Precursors

A 1971 Bulletin on Narcotics notes: :'' Article 2, in paragraph 4 of the original text, carried over the concept in Article 3 (3) (iii) of the Single Convention, and required the application to a "precursor " – i.e. a substance "readily convertible" into a substance under control – of measures of control. In Vienna the complexity of controlling precursors of psychotropic substances was agreed to be so overwhelming that no absolute obligation to control them was provided. The new article 2 in paragraph 9 asks Parties "to use their best endeavours" to apply "such measures of supervision as may be practicable" to substances which may be used in the illicit manufacture of psychotropic substances, i.e. their precursors and possibly also substances essential in the chemistry of manufacture.'' This provision was eventually judged to be inadequate, and was strengthened by the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances's precursor control regime, which established two Tables of controlled precursors. The Commission on Narcotic Drugs and International Narcotics Control Board were put in charge of adding, removing, and transferring substances between the Tables.

Penal provisions

Article 22 provides: :''1. (a) Subject to its constitutional limitations, each Party shall treat as a punishable offence, when committed intentionally, any action contrary to a law or regulation adopted in pursuance of its obligations under this Convention, and shall ensure that serious offences shall be liable to adequate punishment, particularly by imprisonment or other penalty of deprivation of liberty.'' :''1. (b) Notwithstanding the preceding sub-paragraph, when abusers of psychotropic substances have committed such offences, the Parties may provide, either as an alternative to conviction or punishment or in addition to punishment, that such abusers undergo measures of treatment, education, after-care, rehabilitation and social reintegration in conformity with paragraph 1 of article 20.'' Conspiracy, attempts, preparatory acts, and financial operations related to drug offenses are also called on to be criminalized. Parties are also asked to count convictions handed down by foreign governments in determining

treaties are "desirable", although a nation retains the right to refuse to grant extradition, including "where the competent authorities consider that the offence is not sufficiently serious." As with all articles of the Convention on Psychotropic Substances, the provisions of Article 22 are only suggestions which do not override the domestic law of the member countries: :''4. The provisions of this article shall be subject to the provisions of the domestic law of the Party concerned on questions of jurisdiction.'' :''5. Nothing contained in this article shall affect the principle that the offences to which it refers shall be defined, prosecuted and punished in conformity with the domestic law of a Party.''


Treatment and prevention

Article 22 allows Parties, in implementing the Convention's penal provisions, to make exceptions for drug abusers by substituting "treatment, education, after-care, rehabilitation and social reintegration" for imprisonment. This reflects a shift in focus in the war on drugs from incarceration to treatment and prevention that had already begun to take hold by 1971. Indeed, in 1972, a parallel provision allowing treatment for drug abusers was added to the Single Convention on Narcotic Drugs by the Protocol Amending the Single Convention on Narcotic Drugs. Article 20 mandates drug treatment, education, and prevention measures and requires Parties to assist efforts to "gain an understanding of the problems of abuse of psychotropic substances and of its prevention" and to "promote such understanding among the general public if there is a risk that abuse of such substances will become widespread." To comply with these provisions, most Parties financially support organizations and agencies dedicated to these goals. The United States, for instance, established the National Institute on Drug Abuse in 1974 to comply with the research requirement and began sponsoring Drug Abuse Resistance Education in 1983 to help fulfill the educational and prevention requirements.

are under schedule 2 because they began life with medical use. But even though they are scheduled, the system is not really working for these illegally produced drugs. One of the main limitations of the control system is that the Psychotropic Convention was not designed to control illicit markets. It was designed to control and regulate legitimate pharmaceutical markets to prevent their diversion into illicit markets.'' The report mentioned proposals to increase the flexibility of scheduling drugs under the Convention and to amend the drug-control treaties to make them more responsive to the current situation. Neither proposal has gained traction, however. Due to the ease of manufacturing methamphetamine, methcathinone, and certain other stimulants, control measures are focusing less on preventing drugs from crossing borders. Instead, they are centering on increasingly long prison sentences for manufacturers and traffickers as well as regulations on large purchases of precursors such as

and pseudoephedrine. The International Narcotics Control Board and Commission on Narcotic Drugs help coordinate this fight by adding additional precursors to the Tables of chemicals controlled under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. In 1997, ECOSOC called on nations to help enforce international law by cooperating "with relevant international organizations, such as

That resolution also called on governments overseeing precursor exports "to inquire with the authorities of importing States about the legitimacy of transactions of concern, and to inform the International Narcotics Control Board of the action taken, particularly when they do not receive any reply to their inquiries". Pockets of high-intensity clandestine production and trafficking, such as rural southwest

Canadian noncompliance

In 2000, the International Narcotics Control Board chastised Canada for refusing to comply with the Convention's requirement that international transactions in controlled psychotropics be reported to the Board. INCB Secretary Herbert Schaepe said: :''From Canada there is just a big, black hole. We don't know what is going into the country, nor coming out. We cannot monitor the international movement of these substances, which is our mandate. The lack of controls in Canada means that they could be destined for fake companies that will divert them into the hands of traffickers. Traffickers in third countries could be getting them through Canada. Normally, Canada has a very good reputation for fulfilling its international obligations, but here it is just breaking the treaty – a treaty that it ratified a long time ago. It is very disturbing.''


Licit drug problems

In an unusual departure from its normally pro-industry leanings, the INCB issued a press release in 2001 warning of excessive use of licit psychotropics: :''. . . the Board points to loose regulation, unreliable estimates and information regarding medical needs, aggressive marketing techniques and improper or even unethical prescription practices as the main reasons for the oversupply of such controlled substances as

Easy availability leads to overconsumption of such substances, either in the form of drug abuse or by fuelling a culture of drug-taking to deal with a variety of non-medical problems. . . Insomnia, anxiety, obesity and child hyperactivity as well as various kinds of pain are listed among the most common problems to be treated by prescribing psychotropic substances. The Board is especially concerned that preference is given to quick solutions without looking at the long-term effects, as prolonged, excessive consumption of such drugs could result in dependency and other physical and mental suffering.'' The Board also warned that the Internet provides "easy access to information on drug production and drug-taking," calling it "a growing source of on-line drug trafficking."
