Does marijuana hurt your body in any way?
There is some damage to the lungs caused by marijuana smoke
inhalation. (However, note that marijuana does not necessarily have
to be smoked, it can also be brewed as tea.) Interestingly,
marijuana smoke has not been found to be carcinogenic, unlike
cigarette smoke. However, marijuana smoke is still an irritant to
the lungs and can contribute to the eventual development of
emphysema.
