When was smoking harmful to health printed on the cigarette case?

On August 28th, 2005, the worldwide International Framework Convention on Tobacco Control came into force in China, and China officially fulfilled its obligations under the Convention.

The International Framework Convention on Tobacco Control stipulates that the packaging of tobacco products must be marked with warnings that smoking is harmful to health, and its area shall not be less than 1/3 of the visible area of the packaging.

From April 1 2002, all cigarettes produced and sold in China will adopt new cigarette packaging marks. The font size of warning words will increase, and English warning words will be cancelled. The color difference between the font of the warning word and the background of the warning word area should be obvious.
