Evidence shows that smoking harms nearly every organ of the body. Tobacco use is the cause of the majority of lung cancer cases, and it has been linked to many other types of cancer.

Tobacco is the second leading cause of death globally, causing nearly five million deaths a year, WHO reports. Estimates show that it will prematurely kill ten million people a year by 2020 if current trends are not reversed. Tobacco is the only legal product that causes the death of half of its regular users. This means that out of 1.3 billion smokers, 650 million people will die prematurely.

57 Countries, 2.3 Billion People

"Already 57 countries have become Party to the WHO FCTC, representing 2.3 billion people. Its entry into force is a demonstration of governments' commitment to reduce death and illness from tobacco use," said Dr. LEE Jong-wook, WHO Director-General.

"I encourage all countries to become Party to this Treaty, and to implement the range of measures which will make tobacco use less and less attractive to people. This can result in millions of lives saved, and that is where the real success of this Treaty resides," he added.

On Sunday, the provisions of the Treaty will be legally binding for the first 40 countries that became Contracting Parties before November 30, 2004. Seventeen additional countries have become Party to the treaty since then. For these, and every country which becomes Party from now on, the Treaty becomes legally binding 90 days after their date of deposit of the instrument of ratification or equivalent at the United Nations Headquarters in New York.

Now, with the entry into force, countries Party to the WHO FCTC are bound to translate its general provisions into national laws and regulations. These countries, for example, will have three years from the day it enters into force for that country to implement measures to ensure that tobacco packaging has strong health warnings, or five years to establish comprehensive tobacco advertising, promotion and sponsorship bans, among others.

Fewer Loopholes for Tobacco Industry

"Many countries have already put these measures in place," said Dr. Vera Luiza da Costa e Silva, Director of the Tobacco Free Initiative at the WHO. "The difference for global tobacco control is that countries Party to the Convention will be able to implement these and other measures, especially those with cross-border implications, in a coordinated and standardized way. This will leave fewer loopholes for the tobacco industry, which currently finds ways to circumvent national laws."

Evidence shows that smoking harms nearly every organ of the body. Tobacco use is the cause of the majority of lung cancer cases, and it has been linked to many other types of cancer, such as cervical and kidney cancer.

Other health risks associated with tobacco include heart attacks, strokes and other cardiovascular diseases; bronchitis, asthma and other respiratory diseases, as well as infertility. Tobacco use continues to expand, especially in the developing world, where currently half of the deaths due to tobacco occur. If current trends continue, seven out of every ten deaths due to tobacco will occur in the developing world by 2020.
