Which schedule is described as cannot be prescribed?

• A. Schedule II
• B. Schedule I
• C. Schedule III
• D. Schedule IV

Answer: (B)

Scheduling classifies controlled substances by abuse potential and medical use. Substances with no accepted medical use and a high potential for abuse fall into the most restricted category. They cannot be prescribed or dispensed and are limited to research with special authorization. That’s why the schedule described as cannot be prescribed is the one with no accepted medical use, i.e., Schedule I. Examples often cited include heroin, LSD, and federally, marijuana. In contrast, the other schedules involve drugs with accepted medical use and can be prescribed under various restrictions, with differences in how strictly they’re regulated (such as requirements for written prescriptions, refills, and documentation).
