Under federal law, which drugs are classified as Schedule I drugs?

• A. Schedule I drugs
• B. Schedule II drugs
• C. Schedule III drugs
• D. Controlled Substances Act

Answer: (A)

Under federal law, scheduling orders separate drugs by their potential for abuse, medical usefulness, and safety. Schedule I is the most restrictive category, reserved for substances with a high potential for abuse, no currently accepted medical use in the United States, and a lack of accepted safety under medical supervision. The question asks which drugs fit this category, so identifying Schedule I drugs aligns with the definition of the most restrictive schedule. The other options refer to different schedules that do have medical uses (Schedule II or III) or to the law itself (the act), not to the category of drugs with no medical use.
