Which drug is the primary one derived from the coca plant?

• A. Schedule II medications
• B. Cocaine
• C. Schedule III medications
• D. Narcotics

Answer: (B)

Cocaine is the primary drug derived from the coca plant. Coca leaves contain several alkaloids, but the principal active compound extracted and used (in limited medical contexts) is cocaine, a stimulant with powerful local anesthetic and vasoconstrictive properties. The other options refer to regulatory categories or a broad class rather than a specific coca-derived drug, so they don’t name the actual substance produced from coca. In practice, cocaine is a controlled substance due to high abuse potential (Schedule II in the U.S.), whereas “Schedule II” and “Schedule III” describe regulatory classifications, and “narcotics” broadly refers to opioids, not cocaine.
