There is an use for it.

I dont doubt it but what are some good uses?
Very good for MCAS and dysautonomia.
Lot of the modern nano weaponry exploits the nicotinic cholenergic receptors. Nicotine displaces them.
Yup, just don't overdo it. I believe the observed benefits can be achieved at around 7mg a day.
Much more than that will cause problems (monopolizing dopamine, vasorestriction, undermine morning wood, etc)
