Y1 - 2018 N1 - T2 - Poisoning & Drug Overdose, 7e AB - Marijuana consists of the leaves and flowering parts of the plant Cannabis sativa. It usually is smoked in cigarettes ("joints" or "reefers") or pipes or added to food (usually cookies, brownies, or tea). Resin from the plant may be dried and compressed into blocks called hashish. Marijuana contains a number of cannabinoids; the primary psychoactive one is delta-9-tetrahydrocannabinol (THC). THC is available by prescription in capsule form (dronabinol [Marinol]) and is available in liquid form for inhalation using electronic cigarette devices. Marijuana can also be inhaled using a vaporizer (such as Volcano), which vaporizes THC without combusting marijuana. THC is used medically as an appetite stimulant for patients with such conditions as AIDS-related anorexia; it also is used as treatment for vomiting associated with cancer chemotherapy, for chronic pain, and for multiple sclerosis, glaucoma, and other disorders. In some US states cannabis products are legal for medical use, and in others for recreational use.
