They have tested it (although poorly). And, they found no risks at all. And, they managed to spin that into e-cigs being "dangerous."
The claim it has anti-freeze in it. Actually, it has 3 ingrediants in some anti-freezes. One is water. One is PG, which is used to make anti-freeze less toxic, ironically (it's also in inhaled medications, food, and hospital ventilation systems). And the last is that they found diethylene glycol in one of the samples, which is toxic in much higher quantities, but harmless in the quantities they found. And here's an interesting fact - there's more diethylene glycol in every nicotine patch and gum (which they approved) than in that one sample! Funny, isn't it?
And I should also note that none of the other studies on e-cigs, including the one conducted by New Zealand Health, found diethylene glycol in ANY of their samples. There's suspicion that the FDA may have contaminated the sample.
You're right, it is all about money. The FDA loses money and support when the number of people paying cig taxes, and buying their drugs for their chronic smoke-related disease, or their ineffective quit-smoking products, goes down. They're protecting their money. It's not about your health - it's about their fortune.
