Guide on Estimating Requirements for Substances Under International Control
The international drug control regime is based on three international conventions: the Single Convention on Narcotic Drugs of 1961 as amended by the 1972 Protocol, the Convention on Psychotropic Substances of 1971 and the United Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances of 1988. The 1961 Convention as amended and the 1971 Convention established control measures for narcotic drugs and psychotropic substances, whereas the 1988 Convention established control measures for precursor chemicals used in the illicit manufacture of narcotic drugs and psychotropic substances. By becoming parties to these conventions, States accept the obligation to implement in their national legislation the provisions of the conventions. For the purpose of this Guide, the substances controlled under the three conventions will be referred to as controlled substances.
