So, regardless of how you feel about the legality and morality of marijuana use, some new studies suggest it may not be as detrimental to health as regular tobacco smoking.
Here are a few articles reporting on the study:
Marijuana Shown to be Less Damaging to Lungs than Tobacco
Pot Smoking Not so Harmful to the Lungs, Study Finds
Marijuana Doesn’t Harm Lung Function, Study Found
I wasn’t really surprised by this, especially since tobacco smokers tend to smoke more leaf volume in a day than pot smokers (who don’t smoke tobacco as well).
