Smoking and Tobacco




my son smokes marijuana and cigeretts, and his lungs collapes while in the hospital, but is marijuana just as bad on your lungs as cigeretts are?


Regarding the effect of the smoking marijuana and/or cigarettes on the lungs, both substances clearly injure the lungs. Tobacco smoke is better studied, killing over 100,000 Americans each year due to lung disease alone (not counting cancer and heart disease). We know that marijuana smoke has similar early effects of irritation, extra mucous production and damage to the lining and air sacs of the lungs. We don't have as much long term information, yet. But, there is no reason to believe that marijuana is any less damaging.
