The argument that weed is bad for you because smoking is bad for you is flawed because you dont have to smoke it, there many other smoke free methods of use, its as simple as that. Also the potency really hasn't gone up very much, in recent years, it just seems that way because there is less shwag around these days. There have always been super potent strains, but when weed first caught on big time in america people didn't know much about it, so the market was flooded with lackluster product. Now people who smoked it casually back then, try the stuff we have now, and think its more potent because they rarely smoked nething better than shwag back in the day.
