It is reported that in August 2003, the International Center for Cancer Research of the World Health Organization identified betel nut as a first-class carcinogen, and listed it as the same category as tobacco, alcohol and other carcinogens. Cases of oral cancer caused by chewing betel nut and then "cutting the face" to save their lives are not uncommon and shocking.
Betel nut is mostly grown in tropical and subtropical areas, with large areas of betel nut cultivation in Hainan and Taiwan provinces.
In Hainan, whether it is in Haikou, Sanya, these cities or in the countryside there are places where betel nuts are sold, because the sales points of betel nuts do not need a very large place, so many people are a big umbrella can be sold, and eating betel nuts in Hainan, whether adults or primary school students have been very common, even if they know that eating betel nuts is harmful to the body, even if eating betel nuts makes their teeth have changed color, but they have chosen to ignore, every day is a variety of betel nuts, Some people like to eat green betel nut, that is, raw and unprocessed, such betel nut sellers will use specific leaves and some lime with leaves to wrap the lime together with the betel nut to sell together, so they will eat a lot every day, they ignore the harm of the news broadcast.
Previously, there was a news report that "more than 60 million people in the country consume betel nut, more than 20 million in Hunan, the proportion of the population in Hunan who consume betel nut is as high as 38.42%" Originally I thought that Hainan as a large planter should have the most sales, but what surprised me was that in addition to Hainan, the people of Hunan, who are more than a thousand kilometers away, have become the largest betel nut consumption place.
In March 2013, the city's media and outdoor advertising have stopped publishing betel nut advertisements.
