There wasn't a whole lot of research on marijuana for a long time because it was illegal to do such a thing. However, since the higher ups have started to see that weed can actually do good things and started slowly allowing it, more research has been done. Not everything you read is true, and you may not have believed it when you read the title of this article, but pot may actually be good for your lungs! 

A study published today in the Journal of the American Medical Association, a legit source, says that not only smoking marijuana does not negatively affect lung capacity, but it may be good for your lungs!

The study has been researching cigarette smokers, weed smokers, and non-smokers for 20 years, since 1985, and basically states that casual marijuana smokers performed better on certain tests than non-smokers.

The casual stoner sees improved lung function, basically because smoking pot is a form of exercise. Heavy pot smokers, defined as people who smoke more than 20 times a month, did not see the same pulmonary benefits.

Even better, smoking weed may help reverse the negative effects caused by cigarette smoking...

THC has anti-inflammatory and immune suppressing properties, which may prevent lung irritation from developing into chronic obstructive pulmonary disease (COPD), a devastating lung disorder frequently caused by tobacco smoking.
