Cannabis, a psychoactive drug which is widely used medically and non-medically, is a broad term used to describe the various products derived from the leaves, flowers and resins of the Cannabis sativa and Cannabis indica plants, or hybrids of the two.
Tetrahydrocannabinol (THC) is the main active chemical in the cannabis plant that gives people who use it a ‘high’. THC affects areas of the brain that control memory, concentration, and coordination. Cannabidiol (CBD) is an active chemical in the cannabis plant that’s used for medicinal purposes.
The levels of THC and CBD vary depending on the plant strain used. Cannabis may be consumed in a variety of ways, including smoking, vapourizing and oral ingestion.
