Does rainn wilson smoke in real life? because in season 5 on the episode stress relief he lightsup his cigarette like a pro

No, I don't think so. I just think that means he's a good actor.

That's A Bunch Of Garbage! I Won't Believe It!

I know I answered this like a million years ago saying he never smoked. Actually he used to smoke, but doesn't anymore. He used to smoke unfiltered cigarettes. SO, yes that's prolly why he lit that cig like a pro. It never really leaves you, spoken by an ex smoker myself.
