Somehow I keep thinking that one of the OEM's is going to load up one of their setups with 0mg juice and take the FDA to court demanding to know how a bunch of stuff assembled into their product can be regarded as a "tobacco product or byproduct" when absolutely nothing in a 0mg setup has any tobacco or by products in it at all.
Then it will come down to the FDA regulating nicotine and only items with nicotine in them.
I'm thinking the one guy who vapes from Cali may do that. I hope so.
