Article 2

Scope of Control of Substances

1. If a Party or the World Health Organization has information relating to a substance not yet under international control which in its opinion may require the addition of that substance to any of the Schedules of this Convention, it shall notify the Secretary-General and furnish him with the information in support of that notification. The foregoing procedure shall also apply when a Party or the World Health Organization has information justifying the transfer of a substance from one Schedule to another among those Schedules, or the deletion of a substance from the Schedules. 

2. The Secretary-General shall transmit such notification, and any information which he considers relevant, to the Parties, to the Commission and, when the notification is made by a Party, to the World Health Organization. 

3. If the information transmitted with such a notification indicates that the substance is suitable for inclusion in Schedule I or Schedule II pursuant to paragraph 4, the Parties shall examine, in the light of all information available to them, the possibility of the provisional application to the substance of all measures of control applicable to substances in Schedule I or Schedule II, as appropriate. 

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. 

5. The Commission, 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, may add the substance to Schedule I, II, III or IV. The Commission may seek further information from the World Health Organization or from other appropriate sources. 

6. If a notification under paragraph 1 relates to a substance already listed in one of the Schedules, the World Health Organization shall communicate to the Commission its new findings, any new assessment of the substance it may make in accordance with paragraph 4 and any new recommendations on control measures it may find appropriate in the light of that assessment. The Commission, taking into account the communication from the World Health Organization as under paragraph 5 and bearing in mind the factors referred to in that paragraph, may decide to transfer the substance from one Schedule to another or to delete it from the Schedules.

2. If a preparation containing a psychotropic substance other than a substance in Schedule I is compounded in such a way that it presents no, or a negligible, risk of abuse and the substance cannot be recovered by readily applicable means in a quantity liable to abuse, so that the preparation does not give rise to a public health and social problem, the preparation may be exempted from certain of the measures of control provided in this Convention in accordance with paragraph 3. 

3. If a Party makes a finding under the preceding paragraph regarding a preparation, it may decide to exempt the preparation, in its country or in one of its regions, from any or all of the measures of control provided in this Convention except the requirements of:

(b) Such authorization shall state the international non-proprietary name, or, lacking such a name, the designation of the substance in the Schedule, the quantity to be exported or imported, the pharmaceutical form, the name and address of the exporter and importer, and the period within which the export or import must be effected. If the substance is exported or imported in the form of a preparation, the name of the preparation, if any, shall additionally be furnished. The export authorization shall also state the number and date of the import authorization and the authority by whom it has been issued. 

(c) Before issuing an export authorization the Parties shall require an import authorization, issued by the competent authority of the importing country or region and certifying that the importation of the substance or substances referred to therein is approved, and such an authorization shall be produced by the person or establishment applying for the export authorization.

In such case the export authorization shall certify that the consignment is exported for such purpose. Each withdrawal from the bonded warehouse shall require a permit from the authorities having jurisdiction over the warehouse and, in the case of a foreign destination, shall be treated as if it were a new export within the meaning of this Convention.

(f) The competent authorities of any country or region through which a consignment of substances is permitted to pass shall take all due measures to prevent the diversion of the consignment to a destination other than that named in the accompanying copy of the export authorization, unless the Government of the country or region through which the consignment is passing authorizes the diversion. The Government of the country or region of transit shall treat any requested diversion as if the diversion were an export from the country or region of transit to the country or region of new destination. If the diversion is authorized, the provisions of paragraph 1 e) shall also apply between the country or region of transit and the country or region which originally exported the consignment. 

(g) No consignment of substances, while in transit or whilst being stored in a bonded warehouse, may be subjected to any process which would change the nature of the substance in question. The packing may not be altered without the permission of the competent authorities. 

(h) The provisions of sub-paragraphs e) to g) relating to the passage of substances through the territory of a Party do not apply where the consignment in question is transported by aircraft which does not land in the country or region of transit.

The international carriage by ships, aircraft or other forms of international public transport, such as international railway trains and motor coaches, of such limited quantities of substances in Schedule II, III or IV as may be needed during their journey or voyage for first-aid purposes or emergency cases shall not be considered to be export, import or passage through a country within the meaning of this Convention. 

2. Appropriate safeguards shall be taken by the country of registry to prevent the improper use of the substances referred to in paragraph 1 or their diversion for illicit purposes. The Commission, in consultation with the appropriate international organizations, shall recommend such safeguards. 

3. Substances carried by ships, aircraft or other forms of international public transport, such as international railway trains and motor coaches, in accordance with paragraph 1 shall be subject to the laws, regulations, permits and licences of the country of registry, without prejudice to any rights of the competent local authorities to carry out checks, inspections and other control measures on board these conveyances.

2. The Board, when calling the attention of the Parties, the Council and the Commission to a matter in accordance with paragraph 1 c), may, if it is satisfied that such a course is necessary, recommend to the Parties that they stop the export, import, or both, of particular psychotropic substances, from or to the country or region concerned, either for a designated period or until the Board shall be satisfied as to the situation in that country or region. The State concerned may bring the matter before the Council.
