Anti-tobacco Advertisment

Global observance
Groups around the world—from local clubs to city councils to national governments—are encouraged by the WHO to organize events each year to help communities celebrate World No Tobacco Day in their own way at the local level. Past events have included letter writing campaigns to government officials and local newspapers, marches, public debates, local and national publicity campaigns, anti-tobacco activist meetings, educational programming, and public art.
In addition, many governments use WNTD as the start date for implementing new smoking bans and tobacco control efforts. For example, on May 31, 2008, a section of the Smoke Free Ontario Act came into effect banning tobacco "power walls" and displays at stores, and all hospitals and government offices in Australia will become smoke free on May 31, 2010.
