That's good to know. And the bath joke was in poor taste. Gotta say it can't be as dangerous as siphoning gasoline (which I did in my youth) or as gross as siphoning fish scum to empty an aquarium (guilty of that too). I'll be careful, promise.
Actually, it's not far from the gasoline, and it's probably worse than the fish scum, both of which I've also done and, respecting the fish scum, more recently than I'd care to admit.
There's an old thread here from Nov about a nic. supplier that was sending out nicotine that was far stronger than the label indicated. In one case, 227mg nicotine was sent in a bottle labeled 100mg. There was some information on that thread about the lethal dose of nicotine. The upshot of it was that it wouldn't take a whole lot more than a few drops of 227mg nicotine, rubbed into the skin, to kill a 120-150 lb. person.
Of course, you aren't getting anywhere near that concentration in your mouth. And you also aren't getting it all at once. Nicotine dissipates from your system fairly fast. But, it's a poison, it's used as an insecticide and it will make you sick if you get too much of it. It will kill pets very easily, especially birds or small mammals like cats. Children, because of their small stature, are also susceptible. If you have small children, keep your nic juice locked out of their reached. A 4 year old might love the taste of that apple flavored juice.
