Which statement about Schedule I controlled substances is true?

• A. They have high potential for abuse and have no currently accepted medical use in the US.
• B. They have an accepted medical use with severe restrictions.
• C. They have potential for moderate to low physical dependence.
• D. They have limited potential for dependence.

Answer: (A)

Schedule I drugs are defined by a high potential for abuse and no currently accepted medical use in the United States, with no accepted safety for use under medical supervision. This is why the statement is true: these substances are the most restricted under federal law and cannot be prescribed or dispensed for medical treatment. The idea of an accepted medical use with severe restrictions applies to substances in other schedules that do have medical use but are tightly controlled. Statements about moderate to low physical dependence or limited dependence point to other schedules where some medical use exists and dependence risk varies. Examples of Schedule I substances include heroin, LSD, and MDMA; federally, marijuana is still treated as Schedule I even though many states authorize medical use.
