What is Cannabis?
Cannabis contains more than 100 chemicals, called cannabinoids. THC (delta-9-tetrahydrocannabinol) is the main “mind-altering” cannabinoid and is most responsible for the “high” associated with cannabis use.
Note: the term "cannabis" is preferred over the commonly used word marijuana. Cannabis refers to the whole plant (Cannabis sativa and Cannabis indica), and the substances extracted from it, whereas marijuana is a term that originally refers to the leaves and flowers of the plant.
