E-cigs by themselves are just a battery and a coil which, when heated, vaporizes the E-juice. To regulate e-cig devices as a nicotine product is simply ridiculous.
If you want to make an argument for regulating anything, it would have to be the E-juice, which contains the nicotine. However, there are E-juices that contain no nicotine at all, for those who've kicked the nicotine addiction but wish to continue vaping.
point taken. thank you.
