Which law identifies the drugs that are dangerous or subject to abuse?

Answer
The correct answer is the Controlled Substances Act of 1970. This legislation was enacted to regulate the manufacture and distribution of narcotics and other drugs that are deemed dangerous or subject to abuse. It classifies substances into schedules based on their potential for abuse, medical use, and safety or dependence liability. Schedule I substances, for example, are considered to have a high potential for abuse and no accepted medical use in the U.S., while lower schedules represent substances with progressively lower potential for abuse and recognized medical uses. This law is crucial for monitoring and controlling drug use in society.
