The good thing is that kids mostly use high quality vapes. For example, the Juul is cited as the most popular in the article. Other popular ones are Junos, Phixes, and Suorins. All of these have their own juices manufactured by the companies, and all these companies are pretty reputable to my knowledge. The Juul has succeeded in part because they designed their own pods that nobody else was producing, so they could guarantee high quality juices.
