Schedule I, II, III, IV, V drugs

In the U.S., drugs are classified into five schedules based on their potential for abuse and medical use. - **Schedule I**: High abuse potential, no accepted medical use (e.g., heroin, LSD). - **Schedule II**: High abuse potential, accepted medical use with restrictions (e.g., cocaine, oxycodone). - **Schedule III**: Moderate abuse potential, accepted medical use (e.g., anabolic steroids, some pain relievers). - **Schedule IV**: Lower abuse potential, accepted medical use (e.g., Xanax, Ativan). - **Schedule V**: Lowest abuse potential, accepted medical use (e.g., cough preparations with low codeine). These schedules help regulate the use and prescription of these substances.
