Controlled Substances Act (USA)

The Controlled Substances Act (CSA) is a U.S. law that regulates the manufacture, distribution, and use of drugs that have a potential for abuse or addiction. It classifies these drugs into schedules (I through V) based on their medical usefulness and risk of harm; Schedule I drugs have high abuse potential with no accepted medical use, while Schedule V drugs have lower potential for abuse. The law aims to prevent drug misuse and illegal distribution while ensuring legitimate medical access. It also establishes agencies like the DEA to enforce these regulations and oversee controlled substances.
