These words are being specifically used to scare people. They are caustic. We know it's a neurotoxin and have for years—if that bothers you, you should not use e-liquid. Again, though, this stuff isn't more dangerous than the household chemicals you own, or even alcohol. Sure, poisonings will happen with e-liquid, but you can say the same about drinking cleaning products or getting hit by a car. Powdered caffeine is available right now completely unregulated, and that can kill you, too. It's just a matter of time with that as well, so shouldn't it be regulated?
