Which drug is a Schedule III substance?

• A. Oxycodone
• B. Marinol
• C. Diazepam
• D. LSD

Answer: (B)

Drug scheduling by the DEA is based on medical use, potential for abuse, and dependence liability. A Schedule III substance has an accepted medical use and a potential for abuse and dependence that is moderate to low (or high psychological dependence with moderate physical dependence) compared with higher schedules. Marinol contains dronabinol (synthetic THC) and is used medically to treat chemotherapy-induced nausea and to stimulate appetite in AIDS patients. It has an accepted medical use and a lower abuse and dependence risk than Schedule II drugs, which places it in Schedule III. By contrast, oxycodone (a strong opioid) is Schedule II due to high abuse potential, diazepam is Schedule IV with a lower but still notable risk, and LSD is Schedule I with no accepted medical use.
