People in all parts of the world are observing "No Tobacco Day". It is the day when the World Health Organization appeals to people to stop using tobacco products. The WHO hopes if people stop smoking cigarettes or chewing tobacco for one day, they will stop permanently. Health experts have warned for years that smoking can lead to heart disease, cancer and other health problems.[1]The WHO says diseases linked to smoking kill at least 2,500,000 persons each year. Still, many people find it difficult to stop smoking. One reason is nicotine, a substance found in cigarettes. Nicotine is a drug. The effects of nicotine are similar to the effects of cocaine and heroin.
    "No Tobacco Day" is aimed at smokers and those who earn money from tobacco sales. So businesses are asked to stop selling tobacco products for 24 hours. Newspapers are asked not to publish advertisements for cigarettes. Two important developments have been observed in recent years. In industrial countries, the number of smokers has fallen about one percent a year.[2]But in developing countries, the number has been rising two percent a year. This is the result of increased efforts by tobacco companies to sell their products in developing countries.
    The World Health Organization has approved plans to help reach its goal of a "smoke-free" world.[3]One urges governments to offer tobacco farmers the chance to earn money by growing other crops. Another involves improved public information campaigns about the dangers of smoking.
