What is the stem of Ding Zhen's electronic cigarette?

The video of Ding Zhen smoking flowed out on the Internet, and his skillful movements were quite different from those of innocent people who had been marketing, which caused netizens to question.

It turns out that the place where Ding Zhen smokes is not a public place, but an electronic cigarette. There is nothing wrong with adults smoking, but the problem is that Ding was really framed. Ding Zhen, who has been promoting on the Internet, is an innocent and flawless image of a teenager. Besides, Ding Zhen and Li Tang Lv Wen both said in interviews that they don't smoke or drink. Now that the smoking video is exposed, Ding Zhen's image has plummeted.

note:

Chengdu Market Supervision shared a video on social platforms, telling the dangers of e-cigarettes. It can be seen from the contents of popular science that nicotine is the main substance in e-cigarettes, and it also has the characteristics of polluting the environment, damaging health and addiction.

According to the World Health Organization, there is still no clear scientific evidence that e-cigarettes help to quit smoking. Moreover, the e-cigarette market is mixed, and the problem of unequal nicotine content identification and detection value is widespread. There are no certain standards for quality control, and there are serious health risks.
