Breathe Deeper With Marijuana
Marijuana smoking, at least at moderate levels, does not harm lungs but actually improves airflow rates and lung capacity. That’s the finding of a recent study published in the January 11, 2012 issue of the Journal of the American Medical Association.
The research team analyzed a large national database to compare the lung function of marijuana and tobacco smokers over an extended period of time. Researchers found that although smoking cigarettes or being exposed secondhand smoke decreases lung volume, smoking marijuana has the opposite effect.
Stefan Kertesz, M.D., a senior author of the study and associate professor in the UAB Division of Preventive Medicine, stated: “Occasional marijuana use was associated with increases in lung air flow rates and increases in lung capacity. Those increases were not large, but they were statistically significant. 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.”
