Which Schedule II stimulant is commonly known as crank or speed?

• A. Amphetamines
• B. MDMA
• C. Dexedrine
• D. Methamphetamine

Answer: (D)

Crank and speed are slang terms that point to a powerful stimulant known for rapid, intense effects. That description fits methamphetamine, a potent central nervous system stimulant classified as Schedule II due to high abuse potential but with limited legitimate medical uses. Dexedrine is a brand of dextroamphetamine, another Schedule II stimulant, but the common street names given—crank or speed—are most strongly associated with methamphetamine. MDMA, often called ecstasy, is not a Schedule II stimulant in typical U.S. classification, and the broader class of amphetamines isn’t tied to those specific nicknames. Therefore, the best answer is methamphetamine.
