Topical tobacco paste is sometimes recommended as a treatment for wasp, hornet, fire ant, scorpion, and bee stings. An amount equivalent to the contents of a cigarette is mashed in a cup with about a 0.5 to 1 teaspoon of water to make a paste that is then applied to the affected area. Paste has a diameter of 4 to 5 cm (1.5 to 2 inches) and may need to be moistened in dry weather. If made and applied immediately, complete remission is common within 20–30 minutes, at which point the paste can be removed. The next day there may be a some residual itching, but virtually no swelling or redness. There seems to be no scientific evidence, as yet, that this common home remedy works to relieve pain. For about 2 percent of people, allergic reactions can be life-threatening and require emergency treatment. For more on this, see bee stings.
As a result, to reduce the harm that tobacco has made to humankind, the World Health Organization(WHO) successfully rallied 168 countries to sign the Framework Convention on Tobacco Control in 2003. The Convention is designed to push for effective legislation and its enforcement in all countries to reduce the harmful effects of tobacco.On November 10, 2003,China signed the Convention. On August 28, 2005, the 17th Session of the Standing Committee of the 10th National People’s Congress formally ratified the Convention, making China the 89th ratifying country. The Chinese government held a launching ceremony for the Convention On October 13, 2005, which became effective in China on January 9, 2006.
