THC (tetrahydrocannabinol) crystals. Tetrahydrocannabinol, also known as THC, is the main psychoactive drug (plant alkaloid) found in the hemp (marijuana) plant, Cannabis sativa. Its pharmacological actions are the result of its binding to specific cannabinoid receptors located in the brain and throughout the body. Effects include relaxation, euphoria, altered space-time perception, enhancement of visual, auditory, and olfactory senses, disorientation, and appetite stimulation. A number of studies indicate medical benefits for cancer and AIDS patients by increasing appetite and decreasing nausea, blocking the spread of some cancer-causing Herpes simplex viruses. It has been shown to assist some glaucoma patients by reducing pressure within the eye, and is used, in the form of cannabis by a number of multiple sclerosis patients for relieving spasm. Other studies indicate a variety of negative effects associated with constant, long-term use, including memory loss, depression and loss of motivation. Synthetic THC, also known under the substance name dronabinol, is available as a prescription drug (e.g. Marinol) in several countries including the USA, The Netherlands, and Germany.
