dude anything you inhale into your lungs aint good for ya
doesnt matter what it is cannabis has nasty chemicals in it aswell, but who cares ya wanna live for ever straight or ya wanna enjoy yourself????????
I definately wouldn't go as far as to say that the chemicals are nasty. thc is not a nasty chemical by any means, and no harm comes from smoking, eating, or vaporizing cannabis, it's been scientifically proven, there has never been a single case of lung cancer in a cannabis only smoker. Yes, it is true that it has like 4 times as much tar as tobacco, but the tar from tobacco is cancerous, the tar from cannabis however is not. And it doesn't even kill brain cells, if this was true, then how come ppl that smoke cannabis have a higher iq than most non cannbis users?
It is also scientifically proven that cannabis enhances psychic abilities.
