Cannabis is a cannabinoid drug, which is a depressant drug. This means that it slows down and interferes with the functioning of the brain and the body.
Cannabis may also have hallucinogenic effects. Hallucinogens affect the brain, producing distortions of the senses, mood and thought.
Cannabis is a plant containing a range of psychoactive chemicals which are currently being researched. The primary compounds contained in the plant that have been identified are the psychoactive cannabinoid THC (delta-9 tetrahydrocannabinol) and the non-psychoactive cannabidiol (CBD).
