I don't smoke often, partially because it's an expensive habit when you're making minimum wage. When I do, which is on average 3-4 times a week, I go all out, though. It's almost an event. 2 friends and I smoke at least an eighth between us in one session, usually more. I also feel that not smoking every day increases your appreciation of the high. I find that my tolerance is easily lowered with taking a few days off.
