Cigarettes we know for sure cause the problem. Have known that for a long time. But heavy weed smokers report some of the same symptoms, especially after long-time use. I know this has been reported by urologists, although I'm not sure if there've been published formal studies. Any loss of erectile function probably has much less to do with the cannabis itself than it does the action of smoking, which tends to make smooth muscles like veins and arteries, more brittle and irritible (less elastic and flexible), and tends to deplete and change blood oxygen levels, at least temporarily. The good news is that few, if any, men tend to smoke as much weed as cigarette smokers smoke cigarettes. The bad news is that most weed smokers also tend to smoke unfiltered weed, so there's not an easy way of knowing if the various other harmful substances in weed smoke might aggravate any ED symptoms sooner because the smoking is unfiltered. The really bad news is we'll probably never know, at least from American studies, since cannabis research is pretty much at a standstill in this country.
