Which natural anesthetic is water-soluble and listed as a Schedule II drug?

• A. Morphine
• B. Amphetamine
• C. Heroin
• D. Cocaine HCL

Answer: (D)

Cocaine hydrochloride is a natural local anesthetic, and its hydrochloride form is water-soluble, which makes topical anesthesia on mucous membranes possible. It also has Schedule II status because it has legitimate medical uses but carries a high potential for abuse. The other options don’t meet all three points: morphine is a natural analgesic (Schedule II) but not used as a local anesthetic and isn’t defined by water solubility in this context; amphetamine is a stimulant with Schedule II status, not an anesthetic; heroin derives from morphine but is not a standard local anesthetic and is not the same Schedule II substance.
