The texts of the three main international drug control 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 are available as an e-book for download.

The revised schedules of narcotic drugs under international control are issued separately under document symbol ST/CND/1/Add.1. The revised schedules of psychotropic substances under international control are issued under document symbol ST/CND/1/Add.2. The revised tables of substances frequently used in the illicit manufacture of narcotic drugs and psychotropic substances under international control are issued under document symbol ST/CND/1/Add.3.

Those addenda will be updated whenever the Commission on Narcotic Drugs takes a decision to amend one of the schedules of narcotic drugs and psychotropic substances under international control or one of the tables of substances frequently used in the illicit manufacture of narcotic drugs and psychotropic substances under international control.
