Marijuana Doesn't Harm Lung Function, Study Says

Smoking Pot Doesn't Harm Lung Function, Study Says

It turns out that although smoking a doobie on your front porch may be illegal, it might not be as bad for your lungs as previously thought. A recent study on marijuana users — and the largest study on this population every conducted — found that even though pot smokers tend to inhale deeply and hold the smoke in for as long as they can handle before coughing uncontrollably exhaling, periodically smoking pot doesn't negatively affect lung function.

The study followed 5,100 men and women over two decades, and whether smoking one joint a day for seven years or once a week for 20 years, lung capacity didn't deteriorate. In fact, some who smoked regularly had slightly improved lung function.

This is by no means a green light to light up the green. Aside from being illegal in most places, those who blaze up suffer from mental health problems twice as much as nonusers. There's also the risk of lung cancer, plus cannabis-induced mental fogginess and impaired coordination could lead to accidents, job loss, and other social implications. Chronic bronchitis and other respiratory problems are also a major risk for marijuana smokers, as well as issues in the bedroom — men that smoked pot daily were four times more likely to have trouble reaching orgasm. Toking also increases your heart rate, which can up your risk of a heart attack.


Like alcohol, smoking pot is considered a rite of passage for many young adults. Although its addiction rate isn't as high as that of nicotine or heroine, many get hooked on the instant feeling of calm that goes along with lighting up, and aren't worried about the possible health risks. Hopefully, this study doesn't give people more reason to toke up.

I hope this study does give people more reason to toke up, or at least speak up about their toking ways. I tried it like most people in my late teens and declared it wasn't for me but now that I'm almost 40, I've rediscovered it as a means for treating chronic pain from Interstitial Cystitis. It's a miracle. Its not as effective as the prescription painkillers I was prescribed but I'd much rather take something natural. As with alcohol, it should be used responsibly. It's a much healthier than alcohol which is straight up toxic. Now that I'm an avocate for it and I speak up, I've learned that many people I know also do it but keep it under wraps. I'm actualy kind of shocked at how many people do it. I think its time people come out of the shadows, unite and legalize it already.

Interesting. As a counter to thechimes, I appreciate reading this information.

I'd like to say that I'm an advocate for marajuana and I agree with what dregstudios just said (esp. about alcohol vs. pot). However, this is not the kind of post I expected or want to see on this website.
