Suppose I'll be DIYing as well.
As hordes of APV, tank, coil, atty manufacturers go out of business as they wait years while the FDA "considers" their applications.
Until some enterprising manufacturer submits their product to the FDA not as a tobacco product but as a Smoking Cessation Device (a medical device) backed by the research that will eventually be performed that confirms it's efficacy.
My Doctor will prescribe an APV and flavorless eliquid.
Walgreens or CVS pharmacists will offer my choice of "flavor shots" to my eliquid (like they do for my child's prescription antibiotics).
From that (and the criminalization of pure nicotine "distillers") states will pass "medical nicotine laws", followed by legalization and control of the nictotine delivery industry.
The legalization and distribution will look very similar to that of mary wanna.(Had to spell it this way)
I'll go to my "Vape Doctor" get my "Vape Card"
Boutique eliquid shops will spring up again
And we will have come full circle from the original FDA vs NJOY litigation that lead us here today.
BTW: Judd Apatow is currently adapting this story into a movie starring Seth Rogan , James Franco, Danny McBride and Woody Harrelson
Set in the year 2029, working title "Nicotine Express--Sons of the Vape"
