Thailand's Psychotropic Substances Act is a law designed to regulate certain mind-altering drugs. According to the Office of the Narcotics Control Board, "The Act directly resulted from the Convention on Psychotropic Substances 1971 of which Thailand is a party." The Act divides psychotropic drugs into four Schedules. Offenses involving Schedule I and II drugs carry heavier penalties than those involving Schedule III and IV drugs. Note that this statute does not regulate most opioids, cocaine, or some amphetamines. The vast majority of narcotic painkillers, along with cocaine and most amphetamines are regulated under the Narcotics Act.
