Cannabis is a general term for marijuana, hashish, and hashish oil products derived from the leaves, flowers and resins of Cannabis sativa, Cannabis indica or hybrid plants.

Methods of consumption include smoking, vaping, ingesting or topical application of cannabis products.

Tetrahydrocannabinol (THC) is the main psychoactive chemical in the cannabis plant. Cannabidiol (CBD), the second most common chemical present in cannabis, counteracts the effects of THC and is often used for medicinal purposes. The levels of THC and CBD vary depending on the plant strain.
