Below is a link to an article (in English) that discusses a new federal law that became effective two days ago in all of Brazil.
For several years, smokers were confined to a separate area of public facilities where their smoking was fairly well controlled, in my opinion.
Now, with this new federal law, there is no more separate area for smoking - there is no smoking allowed in public facilities - period.
