Convention on Psychotropic Substances

The Convention on Psychotropic Substances is a United Nations treaty designed to control psychoactive drugs such as amphetamines, barbiturates, and psychedelics. During the 1960s, drug use increased greatly around the world, especially in Western nations. Inspired by psychedelic advocates such as Aldous Huxley and Timothy Leary, millions of people experimented with powerful hallucinogens, and drugs of all kinds became freely available. Government authorities saw this as immoral and destructive to economic progress. The Single Convention on Narcotic Drugs of 1961 could not ban the many newly discovered psychotropics, since its scope was limited to drugs with cannabis-, coca-, and opium-like effects.
