Is electronic cigarette useful?

Enthusiastic to ask friends about the advantages of electronic cigarettes 20 12-02- 18. No first-hand and second-hand smoke, no odor, no tar, no tobacco, no open flame, no ash, simple and convenient to use, can be used anytime and anywhere, without embarrassment and guilt, and the cost is lower than that of traditional cigarettes. The disadvantages of e-cigarette will not pollute teeth and hurt skin. At present, the e-cigarette market is chaotic, especially the Taobao market, which is full of counterfeit products. Even the best-selling products are not qualified by manufacturers. 3. At present, there is still a lack of effective supervision on e-cigarettes, which leads to an uncertain future. 4. E-cigarettes also have obvious exaggerations. For example, many people advocate that e-cigarettes have the effect of clearing lung toxicity. This is totally illegal propaganda. E-cigarettes are not even medicine, and there is no way to remove lung poison. Moreover, science has also proved that e-cigarettes have no function of clearing lung toxicity at all. E-cigarettes now only replace cigarettes to help quit smoking.
