Cannabis is a term that refers to marijuana and other drugs made from the same plant. Stronger forms of cannabis include sinsemilla (sin-seh-me«-yah), hashish, and hash oil. All forms of cannabis are mind-altering and they all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. There are about 400 chemicals in a cannabis plant, but THC is the one that affects the brain the most. The strength of the drug is measured by the average amount of THC.
