Hello! I am the monopoly manager of China Tobacco in Zhejiang Province. What you have reported is this: With China's accession to the International Tobacco Control Organization, the General Administration of Tobacco of China has adopted warning information on cigarette packaging. There are two versions, one is "smoking is harmful to health, and quitting smoking can reduce the harm to health"; The other is "smoking is harmful to health, and quitting smoking as soon as possible is good for health." So sometimes you buy cigarettes with different slogans.
Don't rely on this to check the authenticity of cigarettes. If you are interested in the identification method, I suggest you consult the local tobacco monopoly bureau.
I hope I can help you!
