A new law taking effect in Vermont makes smoking prohibited in all public buildings.
Beginning Wednesday, workplaces can no longer set aside an area indoors where employees can smoke.
Previous ordinances, including the 1987 Smoking in the Workplace law and the Clean Indoor Air act of 1993, had permitted indoor segregated smoking areas.
Sheri Lynn with the Vermont Department of Health says barns and other agricultural businesses are included under the new law.
Businesses that do not enforce the law could be fined $100.
