I agree with Nullific because - in my opinion; he is the most educated user on this site. No it is not "good" for you, it can give you cancer. But then again - sunlight gives you skin cancer, eating at mcdonalds too much will destroy your liver (I'm not wrong, watch 'Super Size Me'). Most things on this planet are not entirely "good" for you, the toxins in the air we breath from the pollutants are far from "good", all the chemical enhancements and steroids in our food is not "good" for us. Nullific has facts to back up his statements, whats-his-face does not. Obviously marijuana has increased in potency but not to a huge degree, and in theory; we would smoke less now considering it is more potent.

In any case, it is a drug that we all partake in. Like ghostoker and a few others have said - 'everything in moderation.'
