【摘要】：正The harmful role that tobacco plays to human health has already been a common sense.Since 1950s,thousands of epidemiological studies and animal experiments have demonstrated the close relationship between tobacco use and a variety of diseases.Both the smokers and the passive smokers,have a much higher opportunity to suffer from kinds of cancers(especially lung cancer) and other respiratory diseases,which is particularly significant to women and children.Moreover, eleven per cent of deaths from ischemic heart disease,the world's leading killer,are attributable to tobacco use.Based on the WHO's statistics,Tobacco use kills more than 5 million people per year.By the end of this century,tobacco may kill a billion people or more unless urgent action is taken. The economic costs of tobacco use are equally devastating.On one hand,the tobacco-related diseases bring high public health costs;what's more,tobacco users are always less productive due to increased sickness.Many studies have shown that in the poorest households in some low- and middle-income countries,more than 10%of total household expenditure is on tobacco.In other words,tobacco use and poverty are inextricably linked. Therefore,it is an important task through the world that establishing effective tobacco controls.Tobacco control is the single most preventable cause of death among the greatest risk factors for mortality,and it costs little while returns enormously.The World Health Organization Framework Convention on Tobacco Control(WHO FCTC),the first restrict treaty on tobacco in global conventions,was born on such condition.It was adopted by the 56th World Health Assembly on 21 May 2003 and entered into force on 27 February 2005.It has since become one of the most widely embraced treaties in UN history and,as of today,has already 171 Parties. Under the Convention,countries around the world give more and more people with protections against tobacco through making laws and regulations.Based on WHO Report on The Global Tobacco Epidemic,2009,nearly 400 million people newly covered by tobacco control measures in 2008.Even though,there is still considerable work to be done.Less than 10%of the world's population is covered by the measures. As youth students,we have the duty and responsibility to contribute ourselves to the action. We can do something,just through our daily life,through our campus.Establishing smoke-free campus is very significant,not only in keeping our health,but also in telling more and more people how harmful the tobacco is,how important the tobacco control is,and make more and more people enjoy the smoke-free environment,and the happiness of health. The article will begin with the relationship between the tobacco and health,concluding it through the given clinical researches,and then deep into WHO FCTC to talk about the necessity and the status of tobacco control,at last,put forward some personal opinions on establishing smoke-free campus and responsibility of the youth from the perspective of students.
