THC is strongly fat soluble, which means that THC dissolves readily in fat but cannot dissolve in water or in blood. It is well known that fat-soluble drugs operate slowly. Most of the THC entering the body is stored in fat, which releases it slowly over many weeks. When a person smokes pot regularly, a large supply of THC builds up in the body's fat, and its slow release into the blood produces continual sedation. Most pot smokers also drink alcohol heavily and, because THC inhibits nausea, a pot smoker can consume a lethal dose of alcohol without getting sick and vomiting.
Teens often play around with pot, thinking it is harmless fun and no different from alcohol.
They don't realize that THC is building up in their bodies and keeping them sedated all the time. With their minds confused by marijuana, it is difficult to escape from the trap. It takes over a month of abstinence before a regular pot smoker can think clearly again, and THC can be detected more than two months after a person quits pot. Because marijuana operates so slowly, its harm is obscured and the damage is often attributed to other drugs used by the pot smokers. Nevertheless, medical evidence has proven that marijuana itself severely damages the brain, the chromosomes, the hormones, the lungs, the immune system, and the sex and reproductive organs.
