Crack is derived from which substance?

Crack is derived from cocaine, specifically in the form of cocaine hydrochloride, which undergoes a chemical process that converts it into a crystalline form suitable for smoking. This transformation involves using a mix of baking soda and water, which creates the solid, rock-like substance known as crack cocaine. The smoking of crack allows for rapid absorption into the bloodstream, leading to an immediate and intense euphoric effect, making it particularly addictive.

The other substances listed, such as heroin, marijuana, and MDMA, are distinct drugs with different chemical structures and effects. Heroin is an opiate derived from morphine, marijuana is a psychoactive plant, and MDMA is a synthetic drug known for its empathogenic effects. Each substance has its own unique pharmacology, making them separate from crack cocaine. Understanding the origins of crack helps in grasping the broader context of drug classification and its implications in law enforcement.
