Correction. There are exactly 0 cases of anyone overdosing on cannabis alone. There is no lethal dose. The worst that would happen if you smoked or ingested too much is you'd fall asleep for a long time. And probably wake up with the munchies.

I don't use marijuana myself, but growing up I had a number of good friends that did. There is certainly a psychological effect to chronic use. Those who went overboard didn't tend to do much with their lives. But I wonder if, even in the absense of marijuana, if these folks would ever have aspired to be very successful. On the other hand, I know several people who still use it fairly regularly who have done fairly well for themselves, so that tendency can certainly be overcome.

I'm of the opinion that if someone wants to smoke marijuana or drink alcohol or shove hot peppers up their nose, as long as they aren't hurting others it's their own business.
