I think that the banning of smoking in clubs, pubs, and cafes had a significant effect. Now if you want to smoke you need to leave all your friends who don't smoke leave the club and then queue to get back in. Doing this makes you feel like an outsider to your own friendship group. I know the clubs complained bitterly that it lowered their revenue.
