Section 13: Dangerous drugs in transit

(1) No person shall bring any dangerous drug to Nigeria in transit unless-
(a) the drug is in course of transit from a country from which it may lawfully be exported, to another country into which such drug may lawfully be imported; and
(b) except where the drug comes from a country not a party to the Convention, it is accompanied by a valid and subsisting export authorisation or diversion certificate, as the case may be.
(2) Where any dangerous drug in transit is accompanied by an export authorisation or diversion certificate and the Comptroller-General of the Customs Services has reasonable grounds for believing that such authorisation or certificate is false, or that it has been obtained by fraud or wilful misrepresentation of a material particular, it shall be lawful for the Comptroller-General of the Customs Services to seize and detain the drug to which such authorisation or certificate relates and upon being satisfied that such authorisation or certificate is valid or has not been obtained by fraud or misrepresentation as aforesaid, the Comptroller-General of the Customs Services shall release the drug.
(3) Where the dangerous drug in transit is not accompanied by an export authorisation or diversion certificate by reason of the fact that the drug comes from a country not a party to the Convention and the Comptroller-General of the Customs Services has reasonable grounds for believing that such drug is being conveyed in an unlawful manner or for an unlawful purpose or is in course of transit for the purpose of being imported into another country in contravention of the laws of that country, it shall be lawful for the Comptroller-General of the Customs Services to seize and detain the drug.
(4) Where a dangerous drug brought into Nigeria in transit is landed, or trans-shipped in Nigeria, it shall remain under the control of the Comptroller-General of the Customs Services and shall be moved only under and in accordance with a removal licence granted in pursuance of section 14 of this Act.
(5) Nothing in this section contained shall be deemed to apply to any dangerous drug in transit by post or in transit by air if the aircraft passes over Nigeria without landing, or to such quantities of dangerous drugs as may, bona fide, reasonably form part of the medical stores of any ship or aircraft.
