Schedule IV substances have which characteristics?

• A. Substances with low potential for abuse, potential for limited physical or psychological dependence, and an accepted medical use.
• B. Substances with high potential for abuse and no medical use.
• C. Substances with moderate potential for abuse and moderate dependence.
• D. Substances with no potential for abuse and no medical use.

Answer: (A)

Schedule IV substances are defined by having a relatively low potential for abuse compared with Schedule III, a currently accepted medical use in the United States, and the possibility of limited physical or psychological dependence relative to Schedule III. The described option matches those three criteria: low abuse potential, limited dependence, and accepted medical use.

Substances with a high potential for abuse and no medical use describe Schedule I, which lacks accepted medical use. Moderate potential for abuse and dependence aligns more with Schedule III, which has medical use but higher abuse risk. No potential for abuse and no medical use isn’t consistent with any schedule, since most scheduled substances have at least some medical use or evidence of abuse potential.
