Marijuana Smoke Does Not Harm Lungs: Read the 2012 JAMA Study

A New Journal of the American Medical Association Study Suggests That Smoking Marijuana May Not Harm Your Lungs. Here is the Study

Attention pot smokers: a recent study in the prestigious Journal of the American Medical Association suggests that marijuana smoking may not harm your lungs. A study that appeared in the Journal of American Medicine took "repeated measurements of pulmonary function and smoking over 20 years in a cohort of 5115 men and women in 4 US cities."

What did the marijuana smoke study find?

"Occasional and low cumulative marijuana use was not associated with adverse effects on pulmonary function."

The New York Times translates the study into English, quoting a doctor not involved with the study who states:  "essentially there is no significant relationship between marijuana exposure and impairment in lung function.”

So if you like to light up, your lungs may not end up bothering you too much in the future. Of course, you're not out of the woods entirely. The New York Times does point out that marijuana "causes impairment that reduces attention, lowers motivation and heightens the risk of accidents."

Here is a link to an abstract of the Marijuana smoke study in the JAMA. The full study can be purchased here.
