I've been smoking daily for 3 years now, almost to the exact day. The trick is to take a tolerance break once or twice a year, this helps with quitting so much, but you have to start early. I have had 2x one month long breaks, 3x two weeks breaks, and a 20 day period where I only smoked 2-3, as well as a couple random 2-3 day breaks due to no money. I'm on day #2 of my most recent break, which is actually set to end on Wednesday, so it's not a long one at all, but believe me, I'm experiencing zero withdrawal, in fact, I feel damn good, I dreamed for the first time in a long time last night and the dream was so vivid. I have a bit of a headache, and I'm agitated as fuck, but that is not weed withdrawal, that is the Tobacco. I smoke 4 cigarettes a day and yesterday I only had one, today, none so far. I plan to quit that once I start smoking weed again, or once my next pack is gone. This cutback is not by choice, believe me if I could have a cigarette right now I would, unfortunately it is not viable for another hour and a half. FUCK.
Weed withdrawal is nothing though...
