http://www.cnn.com/2006/HEALTH/05/24/pot.lung.cancer.reut/index.html now go show it off to your anti-pot buddies.
I just love how CNN tries to weasel in some crap about a random doctor trying to say MJ causes cognitive impairment (?) and chronic bronchitis--not if you vape it or eat it.. So why is it illegal still. Hard liquor is legal.
he wasn't saying tar is added to either, he was telling you that tar is produced when you combust cannabis/tobacco (and any plant matter, afaik).
lol haven seen u in a while bill good to noe ur back, ye back in the days when not everyone knew about all the lies I remember having this police officer coming in and talking about drugs. To this day I still remember what he said back then in grade 6 "Marijuana will kill your brain cells and ruin your life. You will become homeless and live on the streets. Even the first time you do it you'll get addicted". To this days those lies haunts me but whats worse is how children can easily be brainwashed and following and ideology created by someone else.
what puzzles me is that it showed no increased risk...i would think smoking anything would increase risk
