Marijuana

Marijuana smoke does contain carcinogens that will irritate the lungs

Contains 50-70 percent more carcinogenic hydrocarbons than tobacco smoke.

Marijuana users usually inhale more deeply and hold their breath longer than tobacco smokers do, which further increases lungs' exposure to carcinogenic smoke

Marijuana smokers show dysregulated growth of epithelial cells in their lung tissue which could lead to cancer Source: National Institute of Drug Abuse, National

Is Marijuana Addictive?

Most people who smoke marijuana smoke it only occasionally. A small minority of Americans - less than 1 percent - smoke marijuana on a daily basis. An even smaller minority develop a dependence on marijuana. Some people who smoke marijuana heavily and frequently stop without difficulty. Others seek help from drug treatment professionals.

Marijuana does not cause physical dependence. If people experience withdrawal symptoms at all, they are remarkably mild.

It can lead to addictive behaviors, like compulsive drug seeking and abuse despite its known harmful effects.
