I happily smoke pot while illegal if it happens to be around and someone else provided it and I don't have to drive that day or do anything the next day. I chipped in or did favors not to be a mooch but never bought it directly myself, nor posessed any. None in my car, my house etc.
So that means very infrequently. Depends how many and what kinds of parties I found myself at that year.
I totally like it, will not hesitate if conditions are right, and the only reason I stayed away not doing any more than that was it wasn't worth the risk.
Even today I don't risk it because sometimes I drive across many state lines and I don't want to worry about keeping track of where I might possibly get in trouble if I piss off a cop at a traffic stop, which I am likely to do.
I don't think it's so crazy that there are pot smokers that can take it or leave it. Merely, you would probably never have realized I was a pot smoker, because I don't talk about it all the time for no reason, or even think about it. We'd have to be not merely aquaintances, but we'd have to sometime be at the same party at the same time with the other conditions met. You can't count these people that you have no way to know to count.
