I had a job once where my manager and the CEO were both fairly frequent smokers, and so the people at the company that smoked would go outside and join them on their smoke breaks. I noticed that these people were frequently the ones who got bonuses and the benefit of the doubt compared to the people who didn't smoke, I think simply because they had more exposure with the leaders.

I didn't (and don't) smoke, so it was always a bit awkward for me. I suppose I could have just hung out with them as they smoked and I didn't, but I never did that.
