@Mazinny This raises a very interesting scenario.
I am certain Flavourarts can pretty much publish anything on their web
site they want. On the other hand any US based e-liquid manufacturer
would be prohibited from saying our juice is diketone free as it is
a modified risk claim. I wouldn't be surprised if even a statement such
as "We exclusively use only Flavourart flavors in our products" Would
be claimed by the FDA as a modified risk statement under the new intended
use definition.
We will be finding out real soon what the FDA's boots on the ground will
be up to shortly. Things may start to get very interesting.
