Tobacco control experts said that the countries were ranked by criteria including tobacco prices, the use of tobacco products indoors, the budgets spent to ban smoking, and the advertisement.

A latest survey showed the worst countries in admitting tobacco control measures in Europe are Austria, Germany and Switzerland.

European health experts affirmed at the opening of the conference that if smokers' number would not be lessened in the short run one billion people will die in the 21st century. In the past 20th century 100 million people already died of smoking.

During the three-day conference tobacco experts, together with representatives of health sectors, will discuss the scenarios for achievements and challenges in tackling smoking in Europe.
