Fortinbraz: I'm kinda leaning towards 'prominent warning' in this case, rather than withdrawal.
But you can't be arguing that we should just sell whatever we can get away with, cos then the feds will leave us alone, can you? I don't think that's realistic.
Whether this case is over the line or not you'd probably need other lung specialists to tell you - I'm sure it's a debate that'll be hammered out for many such chemicals over the next few years.
But the fact that there is a line has to be a good thing. Never mind bridges, you wanna buy my anthrax e-liquid?
My desire is for the FDA to treat e-cigarettes as food products, with the ensuing regulations therein. For them to be deemed tobacco products (akin to treating Coca-Cola as a coca plant product) will ensure that overly onerous regulations will be enacted and enforced. This will clearly have a negative impact on small manufacturers and will force market consolidation. It all smells like regulatory capture and we all know who will benefit from that.
Also, I am not saying that (and did not say in my post) that cinnamon flavored liquids get a free pass in my book. In fact, I have not used cinnamon or tobacco flavored e-liquids since I reviewed the aforementioned Farsalinos study. But, it is my choice to avoid those products. There is peril when you swing too far to the risk-averse side, it is a classic slippery slope. In this case, the manufacturer's best step would have been to inform and let the consumer decide how much risk is right for them.
And thanks for the civil discourse.
