Well I know that, but from what i have heard about cigarette butts, im definitely not doing that. anyway besides that I think there are some solutions to reducing the risk of lung damage/cancer when smoking wether it be weed or cigabutts. I'm just being cautious.Once a month no. If you smoke regularly like daily or even every couple days yes eventually just like with cigarettes you will have damage. People argue which is worse for you but in the end in both cases you are breathing in byproducts of combustion and that will harm your lungs over time.
There is a huge difference between breathing car pollution in an average developed place and sucking in concentrated smoke right into your lungs. But go to China and watch how even young people are hacking and coughing..the pollution in cities there is so bad it DOES do damage.
What makes you think they're not black? I've seen surgeries where 25-30 year olds have relatively 'black' lungs - due to pollution. If you see a neonatal's lungs they're pink.The short answer is ... I don't know. Begs another question... is breathing any kind of pollution (car exhaust, fireplace, cooking stove, pollen...) harmful to us. We breath most of those passively everyday, yet we live a long time. So there must be some kind of a cleansing going on inside of the lungs... if there wasn't by the time we were 70 our lungs would be black.
I need to find some government agency to provide me enough weed to smoke, so that I can smoke as much of it that a tobacco smoker smokes. In return, I would expect all that free weed, 100,000 dollars a year, and no taxes. I would "give" my body up for science, they could study my lungs as much as they wanted.I googled that for you ...
Moderate smoking of marijuana appears to pose minimal danger to the lungs. Like tobacco smoke, marijuana smoke contains a number of irritants and carcinogens. But marijuana users typically smoke much less often than tobacco smokers, and over time, inhale much less smoke. As a result, the risk of serious lung damage should be lower in marijuana smokers. There have been no reports of lung cancer related solely to marijuana, and in a large study presented to the American Thoracic Society in 2006, even heavy users of smoked marijuana were found not to have any increased risk of lung cancer. Unlike heavy tobacco smokers, heavy marijuana smokers exhibit no obstruction of the lung's small airway. That indicates that people will not develop emphysema from smoking marijuana.
