Stoners everywhere getting the last laughs

Stoners everywhere getting the last laughs [SFG] This major breaking study is going around the Internet today. Not only is moderate pot smoking okay for your lungs, it might actually be good for them! If this isn't what the government needs to legalize marijuana, what is?
The San Francisco Chronicle says the new study found that only heavy marijuana smokers—those who smoke more than 20 joints a month—were doing serious pulmonary damage to their bodies. The study, results of which were published Tuesday in the Journal of the American Medical Association, found that the lung capacity of people who smoked marijuana was not diminished by regular toking, even among those who smoked once or twice a week.
Wow.

According to the study’s authors, one possible explanation for the results may be THC — the active ingredient in marijuana. The compound is known to combat inflammation, and may be responsible for offsetting irritants that cause lung problems. Dr. Stefan Kertesz, the study’s co-author, also posits that an unintended side-effect of marijuana usage is the strengthening lung tissue as a result of breathing deeply during inhalation. And as if all that wasn’t enough, researchers found that pot smoking might actually improve lung function. “At levels of marijuana exposure commonly seen in Americans, occasional marijuana use was associated with increases in lung air flow rates and increases in lung capacity,” Kertesz said.
