Effects of marijuana use ho

  1. 1. Effects of Marijuana UseThe BrainTHC works by binding to specific receptors in the brain called "cannabinoidreceptors," which are located throughout the following brain structures: • Cerebellum: By binding with the cannabinoid receptors, THC interferes with the normal function of the cerebellum, which controls balance, posture and coordination. • Hippocampus: THC activates cannibinoid receptors in the hippocampus. This affects memory by decreasing nerve cell activity in this area. Short- term memory is the first to be affected. Studies on lab animals show conclusive long-term memory damage. • Cerebral Cortex: THC affects areas in the cerebral cortex that are responsible for sensory perception. As a result of marijuana use, sense of taste, sight, smell, hearing and touch may be altered. • Limbic System: Recent studies in animals suggest that THC produces changes in the limbic system, which governs our emotions. These changes, which are most evident during withdrawal from THC, are similar to those observed after long-term use of cocaine, heroin and alcohol.The LungsMarijuana leaves contain more coal tar than tobacco leaves, which increases thepotential for chest colds, bronchitis and lung cancer. Because they are smoked furtherdown and the smoke is held in the lungs longer, two marijuana cigarettes areestimated to have the same carcinogenic potential as a pack of regular cigarettes.The Reproductive SystemBecause it is fat soluble, THC binds to areas of the body with high fat content, such asthe testes and ovaries. In males, marijuana may decrease testosterone production tothe point that female secondary characteristics, such as breast tissue, may beobserved.PersonalityA lack of motivation appears among many chronic users of marijuana. Called the"amotivational syndrome," this symptom is marked by lethargy, lack of focus and aninability to concentrate on future goals. Some chronic marijuana users become
