I hardly abuse my body besides for smoking, and I'm not going to live my life afraid of hurting myself, this being said I do like being healthy.
Use a bong, don't smoke as often, when you do smoke, smoke a little more and hold your hit in your lungs for a shorter amount of time, go jogging.
Jogging improves overall lung health and enables your lungs to function more efficiently. In this sense it can help fight many lung diseases and help prevent the negative effects of carcinogens. If you're really worried about it, stop smoking.
water bongs also remove some of the thc.... as far as smoking pot and lungs goes, you're definitely getting more tar than you would with cigs, but honestly i think it's not as big of a deal. you're getting resinous build up, yes, but also fairly few "extra" chemicals that contribute to destroying the lungs (unlike cigs). the lungs are capable of cleaning themselves out. if you smoke pot for many years and quit, your lungs will recover significantly in a number of years of not smoking. additionally, if you are extra concerned and/or want to get high your entire life, you can invest in a vaporizer that would not only save your lungs, but would save your wallet as well in the amount of weed you'd have to smoke. you can also eat weed. peace.
Tar doesn't just go away. And out of your 148 posts, I think that maybe 1 was a non retarded question jake. I mean have you seriously ever smoked?
My lungs arent as good as they used to be but at the same rate i can sing better, control my voice and breathing more
me lungs are fucked man " but me heads clear" think i will get another beer /hope i dont get diarrea........./peace/
"geckopelli, what makes you think your lungs are clear?" Frequent MRI's and CAT scans ( last in Jan), as well as the opinons of my three Doctors, one of whom is aware of my toking habits. Also, the breathing machines (I have no idea what they're called) that surgical patients get nowdays confirm this. You see, I'm a medical train wreck, and my systems are monitored regularly.
