Social pressure probably dominates the total cause of smoking reduction, I would bet. I personally won't join a friend outside a bar for their smoke: it's cold and I hate the smell, I'll stay in here thanks. Also a lot of people actively find smoking and smokers disgusting, which eats away at the "cool" factor it used to have.
