One night last week I opened a box from a vendor. Box contained some pg, vg, and a plastic ziplock bag with 3-60ml bottles of 100mg nic.
I opened the plastic bag, started to pull one of the bottles out, and realized that the ink on the label of that bottle was smeared and very strange looking. Then I realized that my fingertips were greasy-feeling. Oops.
I just let the bottle drop back into the bag, sealed it up, grabbed a Kleenex then a baby wipe and got the stuff off my hand.
I'm still here, and so is that sealed-up nicotine. Vendor has reshipped all three bottles. I'm trying to decide if I want to put on some gloves and clean off the bottles that aren't leaking. If I decide to toss it, I guess I have to find out how to do it properly.
Opinions on whether nicotine is a biohazard or not vary all over the Internet. Some people sound like alarmists and some seem like they are far too casual about it.
Anyway, I got some of it on my skin, and I lived.
