I overdosed on nicotine by accident.
I had a bottle of liquid from my refillable vape in my pocket that came open. Yes, it will go through the skin into your system.
ODing on nicotine, at least at the level I did lead to strong anxiety, heart palpitations, tachycardia, and projectile vomiting.
Also, I had a seizure after I finished dying outside and walked into work for my minimum wage job, right in the entry way.
I am epileptic though, so I'm not entirely sure if that related - as I was undiagnosed and untreated at the time. Making minimum wage with no medical benefits, choosing healthcare is a difficult decision over food and a roof.
What if we could do it cheaper and even more inhumane?
