Pot smokers don't puff away lung health: study [View all]

(Reuters Health) - A few hits on the bong now and then don't seem to have any detrimental effects on lung health, suggests a new study.

Researchers found that multiple measures of lung function actually improved slightly as young people reported using more marijuana -- at least up to a couple thousand lifetime joints.

"Previous studies have had mixed results," Kertesz explained. "Some have hinted at an increase in lung air flow rates and lung volume (with marijuana smoking), and others have not found that. Others have found hints of harm."

While marijuana smoke has a lot of the same toxins as cigarette smoke, he added, people who use pot tend to smoke fewer joints each day than tobacco users smoke cigarettes. That and the method of inhaling may offer some relative lung protection, researchers have proposed.
