During the last six years, we have seen a doubling in use among 8th graders and significant increases among high school individuals. The physical effects of marijuana use, particularly on developing adolescents, can be substantial. Marijuana contains one of the most destructive chemicals found in any drug. This chemical is delta-9- tetrahydrocannabinol (THC). THC can stay in a person's body form three weeks to four months. It can harm an individual's memory along with their ability to learn and understand. Regular smoking can very quickly and slowly cause the user not to have any motivation. Marijuana adversely affects the user's immune system, heart, brain and lungs. The most frequent myth I hear from adolescents is that marijuana is safer for their bodies than cigarettes. With each "toke", marijuana smokers inhale more than 150 cancer-causing substances (cigarettes have 43 known carcinogens) and nearly twice as much tar as they would from a tobacco cigarette. Studies have shown that someone who smokes five joints per week may be taking in as many cancer-causing chemicals as a person who smokes a pack of cigarettes every day. Not only does this affect the respiratory system; it also impairs the ability of T- cells in the lungs' immune defense system to fight off some infections. Many pot smokers have more frequent chest colds and dry hacking coughs. Another misconception many people have is that marijuana is not physically addicting. Although individuals don't die from marijuana withdrawal, this does not mean that it isn't both psychologically and physically addicting. Withdrawal can cause flu-like symptoms along with irritability, tremor, anxiety and sleeplessness. These symptoms are usually mild and last for three to four days. Marijuana usage also harms the brain and leads to impaired short-term memory, perception, judgment and motor skills. Perhaps most noticeable to others is that a pot smokers mind is cloudy, their thoughts do not flow smoothly. This is because THC causes a dense material to clog the tiny gaps between nerve cells in the brain, making communication between these cells very difficult. In males, marijuana reduces the levels of the male hormone testosterone. Boys between the ages of 10 and 20 years especially need this hormone because it helps them develop into physically mature men. Furthermore, researchers have found abnormalities in the spermatozoa of heavy smokers. Studies are being done to find out if these can fertilize and egg; therefore causing birth defects. In females, the testosterone level increases. This may cause women to develop dark body hair, facial hair and acne. Because human eggs are present in women from birth, the eggs are vulnerable to damage from prolonged marijuana use. Since THC can accumulate in the reproductive tissues, this can cause problems for a developing fetus because it is still in danger of being harmed by active ingredients in THC. It is also known to interfere with cell division, a process basic to development. This may cause symptoms similar to Fetal Alcohol Syndrome (FAS). These symptoms include small size, varying degrees of mental retardation and abnormalities of the limbs. While current marijuana usage has increased by high school seniors, the proportion of those who believe it is harmful has dropped dramatically. Marijuana is clearly a harmful drug that poses a threat to our children at a critical point in their development. If you have any questions about drugs, or how to talk to your children about drug abuse, there are many resources available to you in your community.
