this is a big issue in the UK at the moment as there is a smoking ban on the horizon... research shows and police investigations have uncovered plans by organized crime gangs to set up illegal bars selling bootleg alcohol and cigarettes and allowing anyone who wants to indulge do so...
so its going to basically make the same criminals who kill to make more money...
given that current technology can make pub and club atmospheres relatively smoke free anyway then it just smacks or more nannying behaviour by the state
