A twenty-year study examining marijuana’s effect on lungs suggests it’s healthier than tobacco!

Moderate marijuana users actually improved their lung function compared to non-smokers and cigarette smokers in the long term study

Breathe easy, tokers! Smoking marijuana in moderate amounts may not be so bad for your lungs, after all.

A new study, published in this month's Journal of the American Medical Association, tested the lung function of over 5,000 young adults between 18 and 30 to determine marijuana's effect on lungs. After 20 years of testing, researchers found some buzzworthy results: regular marijuana smokers (defined by up to a joint a day for seven years) had no discernible impairment in lung activity from non-smokers. 

In fact, researchers were surprised to find marijuana smokers performed slightly better than both smokers and non-smokers on the lung performance test. Why? The most likely explanation seems to be that the act of inhaling marijuana—holding each puff in for as long as possible—is a lot like a pulmonary function test, giving marijuana smokers an edge over their cigarette smoking counterparts.
