Numerous studies have shown marijuana smoke to contain carcinogens and to be an irritant to the lungs. In fact, marijuana smoke contains 50–70 percent more carcinogenic hydrocarbons than does tobacco smoke. Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increase the lungs’ exposure to carcinogenic smoke. Marijuana smokers show dysregulated growth of epithelial cells in their lung tissue, which could lead to cancer

A week after smoking cannabis only 60-70% of the THC has left the body because it is stored in the body fat. It takes about 4-6 weeks before THC is undetectable in the blood. On the other hand, the psychoactive effects are gone after a couple of hours. THC or decomposition products can be detected in urine for a couple of days after the last use. In the urine of chronic users it can even be detected for a couple of weeks after the last use.
