How does the Schedule of narcotics scale work?

The Schedule of narcotics scale, established by the Controlled Substances Act in the United States, categorizes drugs based on their potential for abuse, accepted medical use, and safety. It consists of five schedules, with Schedule I substances having a high potential for abuse and no accepted medical use (e.g., heroin), while Schedule V substances have lower abuse potential and accepted medical uses (e.g., certain cough preparations). This classification helps regulate the manufacturing, distribution, and prescription of these substances to ensure public safety.
