All these analogies to food-prep, laboratories, food-safe, & sterility requirements are poison to the industry.
There should be standards (tacitly self regulated) that are no more strict than tobacco product standards. Volunteering to self regulate similar to FOOD and/or DRUG companies is BEGGING to be governmentally regulated in the same way. This is "Other Tobacco Products". Not "recreational nicotine" (whovever coined that phrase needs to be shot), not McDonalds, and not Glaxo Smith Klein. This is nicotine - derived from tobacco - packaged into a liquid delivery system. Every statement, reference, inference, or notion connecting vaping to FOOD or DRUG is another peg for big government to hang their proverbial hat on. We need to stop it. We don't need to be doing the anti's work for them.
Further, we don't know what we don't know. How about someone listing the flavoring & enhancing ingredients common to eliquids that have been exhaustively tested and found to be safe, harmless, and/or otherwise "appropriate" (love that word) for inhalation along with the levels tested and the determined limits. When I see that list, I'll immediately volunteer to become head zealot for the full-disclosure cause - at my own expense. Until then, and believe me I'm no Polyanna, these things are best left to common sense & market forces. Vote with your wallet, voice your opinions, but open activism when you don't know what you don't know is just loading the oppositions' guns and then jumping directly in front of them.
