Did you notice all the "mays" in that article? The products used in the juices for the cartridges have been in use for a long time in other products in the US. Asthma inhalers, IV medications,food, cosmetics, lotions, air freshners and fog machines to name a few. There are other articles out there that refute the FDA if you're interested.
I'm wondering if the government is more worried about the tax loss from people not buying cigarettes which have proven health risks?
Ya also gotta wonder if the tobacco industry isn't behind some of the government reports.
At this point in time, I'm keeping my mind open. And my airways to boot.
