I've smoked since I was 16...24 now. Back in college it was every single day for 4 years. Now in "adult life" It's only on say a Friday night with the buddies at the ski area, and usually never during the summer. The transition really wasn't hard at all, once you don't have it in possession for about 3 days you just forget about it, atleast that is how it is for me.
I'm high right now, have Friday off of work and its first day of skiing for me tomorrow, starting a little early.
