What schedule is heroin classified under?

Heroin is classified as a Schedule I substance under the Controlled Substances Act. This classification is reserved for drugs that have a high potential for abuse, have no accepted medical use in the United States, and lack accepted safety for use under medical supervision.

Heroin's status as a Schedule I drug reflects its significant risks for addiction and the severe consequences associated with its use, making it illegal to manufacture, distribute, or possess. Other substances classified in Schedule I include marijuana and LSD, both of which similarly demonstrate a high potential for abuse and lack accepted medical applications.

In contrast, other schedules contain substances that may have accepted medical uses but vary in their potential for abuse and dependency. Schedule II substances, for instance, have accepted medical uses but also high potential for abuse, while Schedule III and IV substances have progressively lower potentials for abuse and may be prescribed under more lenient conditions.
