In nature, Cannabis ruderalis typically has the lowest levels of THC, Cannabis sativa has a higher level of THC than it has CBD, and Cannabis indica has a higher level of CBD than it has THC.

Cannabis has been cultivated by humans, for a variety of purposes, since antiquity. So it comes as no surprise that there are several different species and even different varieties within the species, depending on the purpose the plants were bred for. Through artificial selection, different species of cannabis have different properties–some have been used for medicinal purposes, others as food, and others to create clothes, ropes, and other items.
Intoxicating – Any substance that can cause you to lose control of your faculties and alter your behavior is considered intoxicating.
