Controlled Substances Act (CSA)
The Controlled Substances Act (CSA) is a U.S. law that regulates the manufacturing, distribution, and use of drugs and substances that can be abused or are potentially harmful. It classifies drugs into five categories, or "schedules," based on their medical use, potential for abuse, and safety. Schedule I substances, like heroin, are considered the most dangerous and have no accepted medical use, while Schedule V substances, like certain cough medicines, have low potential for abuse. The CSA aims to prevent drug abuse while ensuring that individuals with legitimate medical needs have access to necessary medications.
