Family: Cannabinoids
Cannabis, also known as Marijuana, is a plant containing cannabinoids - a class of diverse chemical compounds that activate cannabinoid receptors - in its flowers. The main cannabinoid in Cannabis is the phytocannabinoid ∆9-tetrahydrocannabinol (THC). CBD is the other main cannabinoid attributed to inducing relaxing, healing, and pain relieving effects, while THC is considered the psychoactive component.
Concerning use worldwide, cannabis is probably the most popular entheogen in the world. This is most likely due to the mildness of its effects in lower doses and the observed pleasantness of these lower doses.
Contemporary use is generally religious/spiritual, recreational or medicinal. Medically, it has been shown that cannabis has positive effects on stimulating hunger in cancer and AIDS patients, reducing nausea, and reducing pain. It can be smoked, vaporized, or eaten (in combination with fatty foods such as dairy-products, as it is lipophilic).
