The smart thing to do is if unflavored liquid is approved, they could sell that by itself and then sell "food flavorings" separately in measured amounts to match the bottles of fda approved unflavored liquid to make it easy for a novice to DIY.Please note that all these figures are generously low, but still prove a point. If a 'mom and pop' type vape shop offers 12 different flavors in 2 different sizes and 4 different nic levels, to the FDA that is 96 separate products, each of which will require a separate PMTA with a cost maybe as low as $350,000. That's a total cost of $33,600,000! That's a pretty expensive pie!
