Study Shows That Marijuana Safer For Lungs Than Cigarettes
A 20-year, federally funded study has found that smoking marijuana once a week, or even once a
day in some instances, does no long-term damage to the lungs.
The study, published today in the the Journal of the American Medical Association, tracked 5,000 individuals across 20 years, and compared their usage of marijuana and tobacco to their health stats.
Cigarette smokers who saw a considerable loss in lung function over time while participants who smoke marijuana as often as once a day for seven years saw no change. And no harmful effects were recorded in individuals who smoked marijuana occasionally for longer.
The study’s authors theorize that THC, which is an active ingredient in marijuana, is known to combat inflammation and may be responsible for offsetting irritants that cause lung problems.
