What's up with the 'if it's natural, it's healthy' - line? I've heard so many people use it, and I really can't see the sense in this; the world's most dangerous toxins, bacteria and viruses are all natural... So is CANCER, goddammit! Nature is full of unhealthy, dangerous shit, and the fact that cannabis makes you cough should be a clear indication that it isn't supposed to go down your lungs...
However, what we should be thinking about is that exhaust fumes from cars and factories affect us way more than smoking stuff... Think about how many particles you breathe in each day just walking down the street.
Sure, smoking cannabis probably causes cancer, but by all accounts, so does breathing in regular air... I'd much rather get high from the poisoning...
