Very sad perspective. Your friend's internal strife sounds concerning. I am a professional in the mental health field and would suggest he/she seek counseling. And, for the record, smoking pot is not the root cause of one's laziness, this is a ridiculous badge. The problem is this: the perception that people who smoke pot are airheads is perpetuated because those of us who are high functioning (professionals, educators, civil servants, etc.) cannot admit that we smoke pot! The folks you refer to are folks who lack descretion and would likely act in a similar way if they did't smoke pot.
