What are Schedule II drugs?

• A. Drugs with no medical use.
• B. Drugs with moderate potential for abuse and no dependence.
• C. Schedule II drugs, defined as drugs with a high potential for abuse, with use potentially leading to severe psychological or physical dependence.
• D. Schedule II drugs include only caffeine.

Answer: (C)

Drug scheduling is about how likely a substance is to be abused and whether it has an accepted medical use under regulation. Schedule II drugs are viewed as having a high potential for abuse, with the possibility of leading to severe psychological or physical dependence, but they do have an accepted medical use that is tightly controlled. This balance—high abuse risk combined with legitimate medical use under strict rules—defines Schedule II substances. Examples include certain opioids and stimulant medications that are prescribed but with stringent limits on dispensing and refills.

The other statements don’t fit this profile: drugs with no medical use are placed in Schedule I; describing moderate potential for abuse would fit other schedules, not Schedule II; and caffeine is not categorized as a Schedule II controlled substance.
