1, tea and cigarettes

Tea and cigarettes, advertised as health preservation, are said to be purely natural and harmless, which is far from the truth. Tests by Shanghai Market Supervision Bureau show that the tar content in some tea and tobacco products even exceeds that of ordinary cigarettes.

2. Electronic cigarettes

Electronic cigarette uses electric heating to convert cigarette oil into steam for people to inhale. Although it does not contain tar, it contains glycerin, nicotine and essence, so e-cigarettes should be strictly regulated.

3. Thin stick cigarettes

Many people think that thin stick cigarettes are safer than ordinary cigarettes because of their small size. However, it is found that the indoor PM2.5 concentration produced by its combustion even exceeds that of ordinary cigarettes, and the concentration of harmful substances in it is also higher.

Try to choose the cigarettes with the latest production date:

Just like food, the date of production is also very important to smokers. Because many formulas have deteriorated or changed their chemical composition before they have completely formed an oxidation reaction with air when they leave the factory.

Therefore, once the expired cigarettes, not only the taste and quality can not be completely guaranteed, but also whether there is any denaturation in the chemical composition is difficult to guarantee. Many activated carbon filters for cigarettes are scientific and the fiber composition is reliable, but can they resist the fierce burning of cigarette tar?

And as the date goes on, there are more defects and problems in the permeability of cut tobacco and the tightness of cigarette paper. Consumers are advised to choose cigarette products of the previous date instead of expired cigarette products.
