List of Schedule 1 Drugs
Schedule I drugs are those that have the following characteristic according to the United States Drug Enforcement Agency (DEA):
- The drug or other substance has a high potential for abuse.
- The drug or other substance has no currently accepted medical treatment use in the U.S.
- It has a lack of accepted safety for use under medical supervision.
According to federal law, no prescriptions may be written for Schedule I substances, and they are not readily available for clinical use.

A substance does not need to be listed as a controlled substance by the DEA to be treated as a Schedule I substance for criminal prosecution. A controlled substance analogue (for example, a "designer drug") is a substance which is structurally or pharmacologically similar to a Schedule I or Schedule II substance, specifically used for human consumption, and is not an approved medication in the United States.
NOTE: Tetrahydrocannabinol (THC, marijuana) is still considered a Schedule 1 drug by the DEA, even though some U.S. states have legalized marijuana for personal, recreational use or for medical use.
