Testing various flavors is exactly what the Italian company Flavor Art is doing. The second recent study mentioned in my article, Clearstream Air, is funded by Flavor Art. I look forward to reading the details after the SRNT presentation.
If a Manufacture could show that a List of e-Liquid Flavorings do not pose a Significant Risk in the form of 2nd Hand Vapor, and a Retailer could show that they Only use Flavorings from the "Approved" List, it would go a Long Way with Policy Makers when deciding if a e-CG/Liquid ban is Necessary. And what type of Regulations are Needed.
I have used the terms ( and taken a Good amount of Flake over it) "Non-Winnable Fight" and "Compromise" when discussing e-Cig/Liquid Policies.
To me, a Non-Winnable Fight would be trying to keep e-Liquids being Sold in a Completely Unregulated Market. Whereas the Compromise would be Support for Regulations along the lines that Flavorings Used in e-Liquids must be come from an Approved List of Chemicals shown to Not Pose an Significant Risk.
I applaud FlavorArt for what they are doing. It is something that lends Credibility to a Position that e-Cigarettes can be Used as Harm Reduction.
The next step would be to have FlavorArt's Test results Verified by an Independent Laboratory so No Claim can be made that the Results were Statistically Biased because FlavorArt Funded the Testing and has a Monetary Interest in the Results.
Let's just pray that all this Doesn't come too late.
