The Narcotic Drugs and Psychotropic Substances Act, 1985, is an Indian parliamentary act that regulates the production, manufacture, cultivation, possession, sale, and consumption of narcotic drugs and psychotropic substances, aiming to control and suppress illicit traffic and drug abuse. It establishes a licensing system for central and state governments and creates provisions for the supervision and regulation of activities related to these substances, enforcing strict penalties for violations. The act also allows for the creation of a national fund to support drug abuse prevention and rehabilitation efforts.
