"The challenge that the FDA has is that they will be challenged by the tobacco industry, as they have been at every step of the way. [The FDA] tried to regulate e-cigarettes earlier, and they lost to the tobacco industry. … So the FDA has to balance moving quickly with moving in a way that’s going to be able to survive the tobacco industry’s highly paid legal challenge."

Looking at formaldehyde first, it seems the higher the PG content, the more formaldehyde will be released. In the case of 50PG/50VG ratio and 100% PG, it seems the higher the voltage being outputted by your device, the higher the levels of formaldehyde will be released. For 100% VG, no formaldehyde is present. With acetaldehyde and acetone however is present in all three groups. With acetaldehyde 100% VG has the lowest level, then 50/50 ratio, than 100% PG. With acetone, 100% VG is still the lowest followed by 50/50 ratio and 100% PG similar to acetaldehyde; however unlike acetaldehyde it seems more acetone is released with the 50/50 ratio when voltage is increased, more than the 100% PG actually.

It makes no sense, from a public health perspective, to ban a product which is almost uniformly used by smokers in an effort to quit smoking or significantly reduce the amount of cigarette consumption, while at the same time, to sanction the sale of the real thing: deadly cigarettes. What Senator Hannon is saying is that he would rather have smokers continue to smoke cigarettes than quit smoking with the aid of a much safer alternative product.
