Hmm, you don't know if it hasn't interfered with his life. I somewhat believe pot is a coping activity, so if he's been smoking all these years, he hasn't learned to cope well with his stressors. So what happens when he stops, you know? For those who smoke regularly, they are simply not showing themselves.

Yea I am biased, mine smoked Pot since mid school. When I first met him I thought he was the greatest thing, but when he stopped to get a better higher paying job (which required drug test)... oh boy.

Heather, it is all up to you, not all stories end up the same way, do what makes you happy
