Schedule I drugs are those that have the following characteristic according to the United States Drug Enforcement Agency:

  • 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.
  • There is a lack of accepted safety for use of the drug or substance under medical supervision.

No prescriptions may be written for Schedule I substances, and they are not readily available for clinical use.

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.
