Marijuana's Effect on Lungs Suggests it's Healthier than Tobacco.
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 discernable 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?
