A recent study published in the Journal of the American Medical Association, on the effects of marijuana, shows that the use of marijuana actually increases lung capacity. The smoker’s lung capacity was actually greater than non-smoker’s.
The research used FEV and FVC. FEV is the amount of air that someone breaths out in the first second after taking the deepest breath possible and FVC is the total volume of air that is exhaled after the deepest inhalation.
Dr. Mark Penscher, from the University of California, San Francisco and lead author of the study said: “FEV and FVC both actually increased with the use of marijuana. There are clearly adverse effects from tobacco use and marijuana smoke has a lot of the same constituents as tobacco smoke does so we thought it might have some of the same harmful effects. It’s a weird effect to see and we couldn’t make it go away.”
The researchers tried to look for errors or other factors that could explain this phenomena using statistical models, but they could not find any.
Marijuana may have beneficial effects on pain control, appetite, mood, and management of other chronic symptoms. Our findings suggest that the use of marijuana for these or other purposes may not be associated with adverse consequences on pulmonary function. Our findings do suggest an accelerated decline in pulmonary function with heavy use of marijuana.
The good news for all you habitual smokers out there: there is still no link between smoking pot and any type of lung or upper airway cancer.
Marijuana have amazing effect on body as it contains THC. THC has anti-inflammatory and immune suppressing properties, which prevent lung irritation from developing into chronic obstructive pulmonary disease (COPD).It also has anti-tumoral effects that have been shown to slow down the growth of a variety of cancers which probably counteracts the potentially tumorigenic effects of the carcinogens in marijuana smoke.
As for smokers, your lung capacity is probably better than that of the average non-smoker. It seems that people who demonize smoking pot will have to find another reason than, “Because it’s bad for your health.”
