Referring to the NJOY video, sure we can split hairs about the ppm or ppb.... What I find interesting is that the company who has been in this a while and has a large stake in the game is openly disclosing, talking about, and willing to produce test results. And they've successfully challenged the FDA and won one already. They aren't trying to avoid the issue, and I am pretty certain they market based on 18 plus. The discussion was insightful on a lot of levels. Collectively the e liquid companies need this level of professionalism, experience, and political pull.
At the 11 minute mark, notice that a former Surgeon General of the US and vocal opponent of BT is on NJOYs board of directors. Think about that for a minute. That brings serious legitimacy to their cause and hopefully to the cause of the broader community.
