NO, most have smoking bans in the USA.

Congress has not issued any nationwide federal smoking bans for any locations. All smoking bans are due to local or state ordinances. 28 states have statewide bans on smoking in all enclosed public places and 10 have no ban on any non-government owned locations. One reason why schools are targeted is because of the toxic properties of second hand smoke and the age of the students.

Smoking shelters were first used many years ago, but are more widely used today due to smoking bans etc.

Smoking bans are controversial for various reasons. I believe some are necessary like bans in places where there are children but there is a lot of evidence that the studies were rigged, look into it. I personally don't believe secondhand smoke is real. How can someone smoke a pack a day for around 30 years(usually more, from what I see I would say the average age to start smoking is around 15-16) before developing cancer
