Y1 - 2022 N1 - T2 - Current Medical Diagnosis & Treatment 2022 AB - Marijuana refers to the crushed dried leaves and flowers of the Cannabis plant. These dried leaves and flowers contain the psychoactive cannabinoid delta-9-tetrahydrocannabinal (THC), which binds to endogenous cannabinoid receptors. Marijuana is usually smoked in cigarettes or pipes but may also be vaporized or added to a variety of foods, beverages, and candies. Resin from the plant may be dried and pressed into blocks called hashish, and solvents may be used to extract THC into highly concentrated oils (butane hash oil). THC has been used medically as an appetite stimulant, as an antiemetic, and in the treatment of a variety of medical conditions. It has now been legalized for both medical and recreational use in an increasing number of US states (https://disa.com/map-of-marijuana-legality-by-state). Toxicity is dose dependent but varies significantly by individual, prior experience, and degree of tolerance. Synthetic cannabinoids (“Spice,” “K2,” “Black Mamba”) are laboratory designed analogs of THC. They have become increasingly popular and are associated with a variety of adverse side effects, including seizures, kidney dysfunction, and serious neuropsychiatric symptoms.
