Although e-cigarettes do not produce smoke by burning tobacco, they still contain nicotine, but the smoke oil inside will still release smoke. This kind of cigarette also contains a lot of nicotine in cigarettes. If others smell a lot of secondhand smoke for a long time, harmful substances will directly contact the alveoli, causing serious damage to the lungs.

Although the composition of e-cigarettes in China is different from that in the United States, medical experts say that the harm of e-cigarettes in China should not be underestimated. China Center for Disease Control and Prevention released the survey results of adult tobacco in China in 20 18 years, which showed that young people were the main users of e-cigarettes in China, and the utilization rate of e-cigarettes among people aged 15-24 was 1.5%.

In the promotion of merchants, marketing slogans such as tar, no burden on the body, no carbon monoxide and no heavy metals are very common, and even many merchants have played the gimmick that e-cigarettes can help quit smoking.

According to experts, it has become common sense that ordinary cigarettes are harmful to human health, and according to regulations, relevant warnings must be clearly printed on the packaging box. However, at present, e-cigarettes on the market have various packages, and there is no similar warning or logo. At the same time, e-cigarettes are more easily confused than ordinary cigarettes because of their numerous tastes and fresh smell.
