Drugs that are classified as schedule I controlled substances have a high potential for abuse, addiction, and no accepted medical use. This is one of five drug schedules.

List Of Schedule I Drugs

Under the Controlled Substances Act, the U.S. federal government classifies all controlled substances, including drugs and chemicals, into five schedules.

Schedule I drugs have the following characteristics:

  • high potential for drug abuse
  • high potential for physical or psychological dependence
  • no accepted medical use

Schedule I drugs are the most strictly regulated of all controlled substances. Controlled substances are drugs or chemicals that are regulated in some way by the federal government.

List Of Schedule I Drugs

Drugs are largely classified by the U.S. Drug Enforcement Administration, which is an agency of the U.S. Department of Justice.

Common schedule I drugs include:

In addition to this list, a number of opium derivatives and chemicals are also classified as schedule I substances.

Are Schedule I Drugs Legal?

Unless specifically authorized, all schedule I drugs are illegal to use, possess, manufacture, or sell in the United States. Criminal penalties vary by state.

An exception to this is marijuana. Marijuana is fully legalized in 16 states, the District of Columbia, and two territories. It is legal for medical use in 36 states and four U.S. territories.

One reason given for this is a lack of substantial evidence to support medical benefits. Although certain medical benefits of marijuana have been identified through some research, the amount of evidence has yet to meet the threshold required by the federal government.

Scheduling a drug, and reclassifying it, is a complicated and drawn-out process that can take time, funding, and substantial research to justify a drug’s classification.

Are Schedule I Drugs Dangerous?

Schedule I drugs are not classified based on whether they are dangerous. Schedule I drugs are believed to have a high potential for misuse and physical or psychological dependence.
