Cannabis is marijuana is weed is the herb. It's a plant genus that produces three species of flowering plants: Cannabis Sativa, Cannabis Indica, and Cannabis Ruderalis. Farmers grow the sativa, indica, and hybrid varieties for their potent flowers. Cannabis Ruderalis is rarely farmed due to its naturally lower THC content and small stature, but breeders have been studying some of it's properties to improve other strains.
