The 1972 Protocol amending the Single Convention on Narcotic Drugs was a protocol that made several changes to the Single Convention on Narcotic Drugs. It highlighted the need for treatment and rehabilitation of drug addicts, instructing parties to take "all practicable measures for the prevention of abuse of psychotropic substances and for the early identification, treatment, education, after-care, rehabilitation, and social reintegration of the persons involved". It also expanded the International Narcotics Control Board from 11 members to 13 members.
