Electronic cigarettes, also known as electronic cigarettes, are mainly used to quit smoking and replace cigarettes. It has the same appearance as a cigarette, a taste similar to that of a cigarette, and even more than the taste of a normal cigarette. It also sucks out cigarettes and sucks out taste and feel like a cigarette.
E-cigarettes have no harmful ingredients such as tar, aerosols, etc., and manufacturers also believe that electronic cigarettes do not have diffuse or lingering secondary smoke. However, some studies suggest that electronic cigarettes still have secondhand smoke. Since electronic cigarettes have always lacked systematic clinical experimental data support, some countries have found that electronic cigarettes are illegal. Some countries have determined that electronic cigarettes must meet drug standards before they can be sold as quit smoking drugs.
In March 2014, Los Angeles decided to ban smoking on some public occasions. This restriction had previously appeared in New York and Chicago.
