The Controlled Substances Act (USA)

The Controlled Substances Act (CSA), enacted in 1970, is a law that regulates the manufacture, distribution, and use of drugs that have potential for abuse or addiction. It categorizes substances into five schedules based on their medical use, potential for abuse, and safety profile — from Schedule I (high abuse potential, no accepted medical use) to Schedule V (lower abuse potential). The CSA aims to prevent illegal drug trafficking and abuse, ensuring controlled substances are used safely and appropriately for medical purposes, while also providing legal standards for enforcement and regulation by agencies like the DEA.
