| hell, breathing the air causes cancer.
anything's possible, but imo, pot is one of the most harmless foreign substances that exists. from my own personal usage and the point that alex raised (how millions of americans use it, and we don't hear much about schitzo epidemics amongst potheads).
edit - some pot does give you a psychoactive high though. i'm not a huge fan of that stuff when i'm with other people, but by myself it's damn cool |
