It's worth pointing out that FDA regulations (or anything else similar) has no relation whatsoever to ecig safety, public safety, public health, protecting children, or anything else like that. It's all about money and nothing else.
The smoking economy is worth over $1 trillion a year and will eventually take a massive hit from ecigs. How much is just a guess, but given time (20 or 30 years perhaps) then a 60% reduction in the smoking economy is very likely.
What is the smoking economy? It's all the funds generated by smoking and all the people who depend on that money. The list is very long, and everyone in the chain has a financial interest in protecting smoking - otherwise their jobs disappear or they take big pay cuts. Everyone from State Attorneys General to 'public health' groups such as cancer orgs depends on smoking. National governments, State economies, and city budgets depend on the tax revenues to balance the books. The States are in the worst position of all as they depend on the immense MSA payments to stave off bankrupty - and those payments are already starting to slide (way ahead of the expected date these payments would react to shrinking cigarette sales caused by growing ecig sales).
All laws banning ecigs, all regulations restricting ecigs, all legislation affecting ecigs, and all voices heard speaking against ecigs are created by or dependent on the smoking economy. Public health is irrelevant, it's all about the money, has always been about the money, and will always be about the money.
Please don't be fooled into thinking that health is important - nothing is of less importance to regulators than your health. Please don't be fooled into thinking that science and evidence are important - these things are completely irrelevant to legislators. All they are concerned with is their mortgage, and the smoking economy pays that. Smoking and pharma are protected, and that's all there is to it.
You need to vote for someone who will do something about it - or just suck it up, it's what you voted for.
