據科學家測定，煙草中含有數百種復雜的化學成分，大部分對人體有害，其中焦油、尼古丁、酚類、醇類、酸類、醛類等40種是有毒和有致癌作用的物質。煙在點燃后，所產生的煙霧，包含了煙草中所有的化學成分，同時比煙草本身又增加了一些有害物質，如一氧化碳和煙焦油等。這是因為除煙草本身外，在制成卷煙的過程中，要在原料中加入一些可可、甘草、糖、甘油、乙二醇等調味、濕潤、產香、助燃物質。這些添加劑雖然本身無害，但在燃燒過程中卻起了變化。例如，在鼠背涂上可可燃燒后產生的煙油，可長出皮膚瘤。甘草中的甘草酸在燃燒后，與其他成分化合，可生成有致癌作用的'多環芳烴。糖與煙草一起燃燒后增加了焦油量，而糖燃燒后的產物是煙中的一個重要致癌物。甘油和乙二醇在燃燒后的物質，不但可能使吸煙者患膀胱癌，而且所產生的丙烯醛可抑制氣管和纖毛分泌物從肺內排出，從而增加患氣管炎和肺氣腫的機會，并使患有這兩種病的人病情加重。
煙對人的危害是多么大啊!所以我們不能吸煙。杜絕吸煙，造福后人。

The Flag of the World Health OrganizationThe World Health Organization (WHO) is a specialised United Nations agency which acts as a coordinator and researcher for public health around the world. Established on 7 April 1948, and headquartered in Geneva, Switzerland, the agency inherited the mandate and resources of its predecessor, the Health Organization, which had been an agency of the League of Nations. The WHO's constitution states that its mission "is the attainment by all peoples of the highest possible level of health." Its major task is to combat disease, especially key infectious diseases, and to promote the general health of the peoples of the world. Examples of its work include years of fighting smallpox. In 1979 the WHO declared that the disease had been eradicated - the first disease in history to be completely eliminated by deliberate human design. The WHO is nearing success in developing vaccines against malaria and schistosomiasis and aims to eradicate polio within the next few years. The organization has already endorsed the world's first official HIV/AIDS Toolkit for Zimbabwe from October 3, 2006, making it an international standard.
The WHO is financed by contributions from member states and from donors. In recent years the WHO's work has involved more collaboration, currently around 80 such partnerships, with NGOs and the pharmaceutical industry, as well as with foundations such as the Bill and Melinda Gates Foundation and the Rockefeller Foundation. Voluntary contributions to the WHO from national and local governments, foundations and NGOs, other UN organizations, and the private sector (including pharmaceutical companies), now exceed that of assessed contributions (dues) from its 193 member nations.
