What Do the FDA Final Deeming Regulations Mean?
First: NO NEED TO PANIC!
Everything that is currently on the market will remain on the market for 2-3 years.
This includes juice, tanks, batteries, devices, accessories, etc.
Nothing major for the industry will be implemented by the FDA for at least 2, if not 3 years.
On the consumer level, the only changes you MIGHT see before this time is free samples and flavor testing regulations may change.
