Cannabis refers to any product of the cannabis plant. Other common names include marijuana, weed, and pot among others.

Cannabis contains more than 100 chemicals called cannabinoids. THC (delta-9-tetrahydrocannabinol) is the main psychoactive chemical that produces the ‘high’ with cannabis. Another commonly referenced cannabinoid is CBD (cannabidiol). Unlike THC, CBD is not psychoactive and will not make you high.
