Tobacco-addicted Bulgaria could have its government propose an absolute ban on smoking in enclosed public places, including cafes, bars and restaurants starting June 1, said its press office.
The small Balkan country, home to the European Union's second-heaviest smokers after Greece, banned the habit in all government buildings, public transport, trains, cinemas, schools and kindergartens in 2005.
But bars, cafes and restaurants were allowed to have separate smoking and non-smoking sections, while establishments smaller than 100 square metres (around 1,100 square feet) could choose for themselves.
"The measure aims to limit smoking and its harmful effects on health as cigarettes are a key risk factor for many socially significant diseases -- oncological, heart and pulmonary," the government proposal said.
Health ministry data show that some 3.0 million Bulgarians, or about 44 percent of the total population, are regular smokers.
