Ordered a bottle from an online store that you should be able to handle by hand, no precautions or gloves really necessary, 48mg/mL salt liquid. I have a juul, which is 59mg/ml, and I've gotten the liquid on my hands before, with no real problems. I opened up the box and grabbed the bottle, and there was a film on it. My hands immediately started burning. In an hour my fingertips went numb and started tingling, and after a couple hours I just started feeling off and slightly nauseous for a couple hours. Still feel slightly off several hours after that. I set the bottle down early on and laid down a few feet away, my face started burning slightly like it was giving off some sort of vapor. I washed my hand off for about 20 minutes and put the bottle in 2 sealed bags. I confirmed that 48mg/mL shouldn't make your hands burn by having someone else put a drop of a different 45 mg/mL salt liquid on their hand and rubbing it in, and then letting it sit for a few minutes, and it didn't burn at all. That agrees with my experience with 59 mg/mL juul liquid coming out and getting in my mouth, it only burned very slightly, sometimes, and it didn't last very long. I'm suspecting this was a high strength nicotine (the film on the outside). Anybody have any idea about this, what concentration would do that?
