I stumbled across this interesting article on the internet this morning
http://health-matrix.net/2013/01/21/nicotine-the-insular-cortex-and-empathy/
It references a couple of recent research papers on nicotine. This quote below really stood out for me>
"As noted in Naqvi’s narrative [1], patient N enjoyed smoking for many years. But, after the stroke, he not only lost his desire to smoke, but was now ‘‘disgusted by the smell”, a condition similar to hyperosmia. The entire frame of reference for perception of what is pleasurable or painful has been shifted. The insula along with the amygdala has been found to be responsible for prejudice against groups that are considered outside the norm [20]. Because of this pathological condition, sights, sounds and smells of individuals that were once normal may now be perceived as something to be avoided or controlled, . . ..a threat. […]
It is interesting the comment about impaired smell, considering that psychopaths have poor sense of smell. I’m not implying that there is a connection between insular stroke and psychopathy, but rather a possible role of the insula in empathetic processes."
This might help explain the number of former smokers who are so violently anti-smoking and also the number of people who are repulsed by the smell of cigarette smoke.
