Does the human body naturally produce small amounts of nicotine?

No. However the body has nicotinic receptors in nerve cells- places where nicotine binds to cause it's psychoactive effects. These receptors are probably also activated by substances created by the body which have a structure very similar to nicotine- it's not as though we'd evolve to all have a very special receptor created for the sole purpose of responding to a drug!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
