I guess to me we need to define the term "smoking pot". I see nothing wrong with smoking pot with friends as a normal person would drink wine with friends. I think some people can even be "into" pot like a wine store owner might be "into" wine and it's not a problem. Smoking pot or any other non-productive activity done compulsively is a big problem.
It's interesting to think about tho - we would question someone who traveled all the way to Amsterdam just to smoke good weed. Would we also question someone who traveled to Bourdeux just to sample the best French wines? I know we all would go crazy over someone traveling to Columbia to sample the world's best cocaines lol What's the diff between them? Legal status? Percieved harmfulness? Real harmfulness? Western tradition? Puritain ethics?
