Although e-cigarettes were born more than ten years ago, it was not until the past two years that people really started to see people using them. Therefore, the tobacco control regulations in many places did not explicitly include e-cigarettes. And because e-cigarettes do not need to be ignited, do not contain pungent flavors, and are more convenient and casual to use, many e-cigarette users also use e-cigarettes in public places. Is this allowed?

can e cigarettes be smoked indoors?
It is recommended not to use e-cigarettes in crowded public places, because it is a non-smoking place, please move to the smoking area. Like cigarettes, the vapor of e-cigarettes also contains nicotine and other dangerous chemicals.
Indoor smoking in public places is generally prohibited. The professional interpretation of “indoor” refers to all the spaces in buildings and structures that are covered by a roof and have a total enclosed area of ??more than 50%. Therefore, smoking should be done outdoors, and the same goes for e-cigarettes.
By analogy, e-cigarettes should not be used not only in shopping malls, restaurants and other places, but also in relatively private gathering places such as meeting rooms, boxes, and dormitories, so as to jointly create a healthier and more comfortable environment…
Smoking is strictly prohibited in buses and subway cars, as well as on high-speed trains and airplanes. Neither cigarettes nor e-cigarettes are allowed to be used. Otherwise, they will not only violate the anti-smoking regulations, be punished by public security, and may even be administratively detained.
