What is the purest form of nicotine? The tobacco leaf..........I suspect you have too much wax in your ears.
1000 mg of pure nicotine is indeed lethal.
Sooner or later, teenagers are going to start abusing the nicotine that goes in the vape pens, once they figure out how powerful it is. I imagine sticking a drop under your tongue would make the blood flow.
the purest form is a liquid and it would take 30-60mg to kill one person, even if absorbed through the skin
