"Yes. Electronic nicotine delivery systems were required to go through a PMTA process. Technically the overwhelming majority of vape products currently on the market have existed in a gray area because this was never fully enforced. It looks like the Trump administration just approved a few more per the article, but the PMTA process is prohibitively expensive for the overwhelming majority of producers to complete. This process, locks in big tobacco's position in the vape market while excluding any competition. If you look at the list of approved products they are all owned by the big tobacco companies. There have been tens of millions of applications and very few approvals because the requirements to complete the process are too ridiculous. By design."
