Pure nicotine is quite toxic. You can extract enough from three or four strong cigars to kill someone in less than a minute. I’ve read that if you squirted a full eyedropper of pure nicotine on the skin of a rabbit it will curl up and die.

This is one of those "gee how scary is that" statements that is extremely misleading. Plants are full of natural insecticides that are quite toxic to humans when concentrated. Even vitamins, when concentrated, can become toxic at low levels, as can many other chemicals found in vegetables. Look at the number of "toxins" in a potato.

Nicotine poisoning and overdose is quite rare, and there is no indication that ingestion at less than toxic levels has any negative health implications, and there is considerable evidence of positive benefits from less than toxic levels of ingestion.

I can't disagree with that but it would apply to just about any substance. I was certainly talking about distilling a very concentrated dosage of nicotine. The first rule of toxicity is dosage. The is arsenic in both broccoli and rat poison. One is healthy for you the other will kill you if you eat it.
