Stoners everywhere should rejoice at this news. After conducting one of the longest and largest studies ever done on marijuana, researchers found that not only does marijuana smoking NOT cause lung cancer or chronic breathing problems but it can actually help to improve lung health.

This is CRAZY news and ultra important to the cause. WebMD has the scoop on this on one:

The study has followed more than 5,000 young adults in four cities for more than two decades. More than half of the people in the study reported smoking tobacco, marijuana, or both.

Over time, researchers repeatedly checked two measures of lung function: One was a test that measured the amount of air forcefully exhaled in a single second. The second test measured the total amount of air exhaled after taking the deepest possible breath.

Those tests help doctors diagnose chronic, irreversible breathing problems like chronic obstructive pulmonary disease (COPD).

Cigarette smoking is a leading cause of COPD. And marijuana smoke contains many of the same chemicals as tobacco smoke.

Unbelievable study! I am so glad that this information came out and people are finally seeing the truth about marijuana. Just like any other substance, if you abuse marijuana it can become a problem for you but if you use it responsibly it is clearly a safer choice than alcohol and tobacco.
