There have recently been a number of legislations regarding passive smoking. In 1986, it was determined that the mere separation of smokers and nonsmokers in the same air space does not eliminate the risks of secondhand smoke. Since then, state and local laws have started to regulate smoking in public. As of 1993, forty-four states and Washington D.C. restrict smoking in public places. In April of 1994, the United States Department of Defense banned smoking in all of their work facilities in the world.
Smoking is banned on all flights less than six hours.
Some airlines offer smoke-free international flights. In November of 1994, United States, and Australia signed an agreement to ban smoking on flights between themselves. The restriction of tobacco vending machines has been enforced in twenty-nine states. Most companies have enforced a smoke-free workplace. Restaurant chains such as Taco Bell and McDonalds, and malls have started to jump on the smoke-free bandwagon.
