Which of the following is a common name for methamphetamine?

Methamphetamine is commonly known by the street name "Crank." This term is often used to describe the potent central nervous system stimulant that affects the brain similarly to amphetamines, but with a much stronger impact. The name "Crank" is believed to have originated from the drug's association with the illicit synthesis process, which often involved using a variety of household products and chemicals.

Methamphetamine is distinct from other substances mentioned. Marijuana is a plant-based drug known for its psychoactive properties but is not chemically related to methamphetamine. LSD, or lysergic acid diethylamide, is a hallucinogen that alters perception and mood, making it entirely different in effects and usage from methamphetamine. Cocaine, derived from coca leaves, is also a powerful stimulant but has a different chemical structure and effects compared to methamphetamine. Recognizing these differences is vital in understanding the nature and risks associated with various drugs.
