The study was published in the January 11, 2012 issue of The Journal of the American Medical Association (JAMA). It reaffirms that smoking pot “does not affect pulmonary function and may actually increase lung airflow rates and lung capacity”. Duh, anyone who’s ever seen that Michael Phelps bong hit pic knows that.
The study also pointed out another well documented fact; tobacco smoke had exactly the effect shown in all previous studies; “increasing a person’s cumulative exposure to cigarettes results in loss of airflow and lung volumes; the opposite was true for marijuana smoke.”
And get this: “Those increases were not large, but they were statistically significant,” Kertesz added. “And the data showed that even up to moderately high-use levels—one joint a day for seven years—there is no evidence of decreased air-flow rates or lung volumes.”
Get ready for the kicker; Dr. Tashkin said he and his colleagues had unexpectedly found in their research that even SMOKING up to THREE JOINTS A DAY did not appear to cause a decrease in lung function. “I think that the bottom line is that there does not appear to be any negative impact on lung function of marijuana smoking,” he said, “and that therefore marijuana is not a risk factor for the development of COPD.

bullshit
What do you mean bullshit? This entire article is based on a TWENTY YEAR STUDY! And it's just one of many proving cannabis smoke has little to no negative affects on the lungs, and in some cases may in fact improve lung health and function.
