The World Health Organization (WHO) and partners will mark World No Tobacco Day on 31st May:

Free yourself! This is WHO’s message to governments on World No Tobacco Day 2013, celebrated on 31 May. A comprehensive ban of all tobacco advertising, promotion and sponsorship is required under the WHO Framework Convention for Tobacco Control. Yet, only 19 countries, representing 6% of the world’s population, have comprehensive national bans. Tobacco kills nearly six million people every year, of which more than 600 000 are non-smokers exposed to second-hand smoke.
