If you’re a frequent marijuana user or someone who’s interested in starting, you are likely asking yourself a serious question: is smoking weed bad for your lungs? A recent study by the University of Alabama answers with a joyous “no, no it doesn’t” hurt your lungs.
This 20-year study of more than 5,000 people found that “occasional” pot use of two to three joints a month showed absolutely no negative impact on the lungs. While researchers did see a slight drop in lung function after 10 years, it was statistically insignificant compared to the severe lung damage caused by smoking eight to nine cigarettes a day over the same period.
Shockingly, their tests actually showed that marijuana smokers actually performed a little better than non-smokers in lung performance tests. They believe this is due to the way that inhaling and holding marijuana smoke in the lungs stimulates pulmonary tests and slightly increases lung strength over time.
So, according to the University of Alabama there’s no harm in lighting up every now and then, just make sure you share with those around you.
