One of my best friends is a dedicated daily pot smoker. By all of society's standards of measurement he is successful. He lives in a big house in the suburbs, has three great kids two of whom are in post secondary education one still in high school, belongs to the local sailing club etc. etc.

It is my observation that it is not the use of pot or booze or whatever one uses to get through life but the strength of one's character that determines his goodness.
