The Convention on Psychotropic Substances is an international treaty established in 1971 to regulate the use of certain psychoactive drugs. It aims to control substances that can lead to abuse and dependence, ensuring they are used for legitimate medical and scientific purposes. The treaty categorizes these substances into different schedules based on their potential for abuse and therapeutic value. Countries that ratify the convention are required to implement measures to monitor and control the production, distribution, and use of these substances. This includes reporting on their manufacture and trade, as well as ensuring that they are prescribed and dispensed responsibly, thereby promoting public health and safety.
