What is an electronic cigarette？

According to Wikipedia, An electronic cigaretteis an electronic device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that atomizes a liquid solution called e-liquid. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most versions are reusable.

Worldwide, increasing numbers of young people are vaping. With access to e-cigarettes, young people's tobacco use has dropped by about 75%.
Most young e-cigarette users have never smoked, but there is a substantial minority who both vape and smoke. Young people who would not smoke are vaping.Young people who smoke tobacco or marijuana, or who drink alcohol, are much more likely to vape. Among young people who have tried vaping, most used a flavored product the first time.
Vaping correlates with smoking among young people, even in those who would otherwise be unlikely to smoke. Experimenting with vaping encourages young people to continue smoking. A 2015 study found minors had little resistance to buying e-cigarettes online.Teenagers may not admit to using e-cigarettes, but use, for instance, a hookah pen. As a result, self-reporting may be lower in surveys.

Electronic cigarettes are very popular among young people, so in the future, electronic cigarettes will become more and more popular.
There are many good e-cigarette stores on the Internet, but the products they sell and transportation and logistics are different. Here I recommend an e-cigarette store, the products in it are quite good, and the website is https://www.vapeciga.com/ .
