From which plant does marijuana originate?

Marijuana originates from the cannabis plant, which is specifically known for its psychoactive properties due to the presence of compounds such as THC (tetrahydrocannabinol). The cannabis plant has been used for thousands of years for various purposes, including medicinal, recreational, and industrial applications. Understanding that marijuana is derived from cannabis is fundamental for discussions related to its uses, regulations, and cultural significance. The other options listed refer to different plants that produce substances with their own distinct effects and uses: the peyote cactus is known for its psychoactive alkaloids, the poppy plant is the source of opiates like morphine, and the coca plant is known for producing cocaine. Each of these plants contributes to different aspects of pharmacology and culture, but only the cannabis plant is associated with marijuana.
