But the call for FDA regulation, like most statist solutions, won't achieve it's stated goals.
So here is the break down of regulations to make products safer for vapers.
The increased barriers to entry that will inevitably result from government regulation will necessarily decrease supply. Doing so kills off the smallest firms first, and with Cigalikes controlling well over half the market shares it's safe to say that these (assuming their tests are without error) tin factories are larger firms.
Regulation is never just simply about safety, as with any human action, incentives play a large role. With the incentive to get involved in the writing of legislation, and manufacture FDA approved loopholes, the larger firms will move in and secure their market shares even more firmly at a reasonable cost. See Monsanto, or Pfizer for further proof of this.
People do care about what they are vaping, after all we did get into this to better our health, so the vape community is already predisposed to being health conscious. People supply a certain level of transparency, and/or testing, and if at a satisfactory price, people choose this option over others that do not satisfy their preference for safety concerns. Transactions, and emerging market regulations like this have made this transition for people every day. See AEMSA, or the footnote here for proof of this.
Of course, the person not well versed in Economics will assume that because one does not wish the Government to do something, one does not want it done at all. As if they claim that food should be provided by the State, and we object, then we object to food being grown at all... No it's simply the State is not an efficient allocation mechanism of any service or product, they not only do not have the means to calculate, but they have no inherent regulation mechanism, as they retain monopoly status.
