As I understood it, the juice will still be legal to sell so long as it goes through an FDA approval for each Nic level of the juice, supplied in glass bottles, and is sealed. Besides how much money it would cost for the testing, this is pretty much a non issue, and plenty in the industry say is a good way to knock out the shady suppliers and manufacturers.
Where did it ever say that non-nicotine flavorings are being deemed a tobacco product? Its just a flavor extract in PG or VG... If its true, this is also the exact reason why most people are fighting against the regulations. While some would be good, coming down with an iron fist like this and crippling an industry is just terrible.
On a more humorous note, one of the vape shops said they would just sell their juice as personal flavored lubricants. Just add nic yourself.
