W: People in all parts of the world are observing "No Tobacco Day". What does it mean anyway?
M: It’s the day when the World Health Organization appeals to people to stop using tobacco products. The WHO insists if people stop smoking cigarettes for one day, they will stop forever.
W: So, what is the target of this year’s "No Tobacco Day"?
M: The target for this year’s "No Tobacco Day" is women. Organizers want to make sure women know the dangers of smoking.
W: But why do many people find it difficult to stop smoking?
M: The reason is nicotine, a substance found in cigarettes. The effects of nicotine are similar to the effects of cocaine and heroin.
W: And what are people supposed to do during this day?
M: "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.
W: Does it show any improvement?
M: Well, generally, yes. In industrial countries, the number of smokers has been falling about 1% a year.
W: What about in developing countries?
M: In developing countries, the number has been rising 2% a year. I think this is the result of increased efforts by tobacco companies to sell their products in developing countries.
W: So, is there any international effort to help the developing countries?
M: Yeah, in fact, several plans have been approved. 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.
