Okay then.
Freaking go put your face over some smoldering wood for a few years and tell me if you feel just peachy.
i mean, this isn't quite the best approach to explain to someone what smoke does to your lungs
not saying that weed is bad in itself, it's just that any kind of smoke, be it from paper, tobacco, wood, or even weed, will end up hurting your lungs at some point.
it irritates the cells and causes mucus growth, and can possibly burn some nerve endings.
