20-Year Study Finds No Decline In Lung Function For Occasional Cannabis Smokers; Lung Function Of Most Marijuana Smokers Improves Over Time
Often, when people hear about the studies which have shown that smoking marijuana doesn’t cause lung cancer, they’ll say something like, “Well, inhaling any smoke, cancer or not, is bound to cause some breathing problems.” Guess what? It doesn’t do that, either.
A report to be published Wednesday in the Journal of the American Medical Association shows that — over a 20-year period — marijuana smokers generally did not experience a loss in lung function, reports Derek Abma at Postmedia News. In fact, many actually had enhanced lung capacity, which one researcher speculated might come from the practice of “deep-lunging” hits to maximize their intoxicating effects.
Whatever the cause, the fact remains that the study showed the lung function of most marijuana smokers actually improved slightly over time.
