All of us have cannabinoid receptors in our brain cells. These molecular targets are the landing sites for thetetrahydrocannabinoids from marijuana, and in this way, interrupting the neural communication pathway that plays an important role in normal brain development and function. The highest density of cannabinoid receptors is found in parts of the brain that influence pleasure, memory, thinking, concentration, sensory and time perception and coordinated movement. Marijuana overactivates the endocannabinoid system, causing the "high" and the proverbial "pot head" appearance that users experience such as altered perceptions and mood, impaired coordination, difficulty with thinking and problem-solving, and disrupted learning and memory. When marijuana is used heavily by young people, their brain development is altered and its effect on memory and thinking may last a long time or even be permanent! Several large long-term studies showed that teenagers who smoked marijuana heavily lost an average of 8 points in IQ, and the lost cognitive abilities were not fully restored. Long-term marijuana users trying to quit experience withdrawal symptoms such as irritability, sleeplessness, decreased appetite, anxiety, drug cravings, drug-seeking behavior and relapse episodes over and over again. Marijuana is addictive, period. Carlos F Acevedo, M.D. psychiatrist Walla Walla - --- MAP posted-by: Jay Bergstrom
