Addressing reporters in Athens, Greek Health Minister Dimitris Avramopoulos said the nationwide campaign is targeted at safeguarding the nation's health, the Ekathimerini newspaper said Wednesday.
The minister cited a recent public survey suggesting that six in 10 Greek smokers support the campaign.
With Greeks considered among the most passionate smokers in the European Union, Avramopoulos said 20,000 Greeks die a year of smoking-related diseases, which annually costs the national health system some $2.8 billion.
The law says all offices, restaurants, cafes and other public places must designate areas for smokers. Managers that fail to respect the law will face fines, the newspaper said.
