The FDA's e-cigarette regs, which took effect last week, struck 2 blows against public health. They are forbidden to share potentially lifesaving information about those products with their customers. See link
It pisses me off. Shops now have to charge for flavor testing, can't sell small bottles anymore because FDA tags won't fit on them and are not allowed to tell you it's safer. I quit smoking almost a year ago and went to the electronic method. My lungs feel 100% fresher, no more stink from cigarettes. This is just another advancement of government control. Vaping has been proven to be as much as 95% safer, unless you are buying from places from China that contain diactyl in their juice. But even then, the amounts are so small the dangers are astronomical. Damn over reaching government.
What you call potentially life-saving information is potentially very misleading information if manufacturers try to claim their products are safe when they're not.
