Which drug is produced from the Cannabis sativa plant?

Marijuana is derived from the Cannabis sativa plant. This plant contains various compounds known as cannabinoids, with tetrahydrocannabinol (THC) being the primary psychoactive component that leads to the drug's intoxicating effects. The process of producing marijuana involves harvesting the plant and typically includes drying and curing the leaves and flowers for consumption.

Other substances listed, such as cocaine, methamphetamine (meth), and heroin, originate from entirely different plants or chemical processes. Cocaine is extracted from the coca plant, meth is a synthetic drug, and heroin is derived from morphine, which comes from the opium poppy. Understanding the source of marijuana as derived from Cannabis sativa distinguishes it clearly from these other drugs in terms of origin and composition.
