Just to add one last thing....based on the above researcher's findings, you could probably hypothesize that people on other medications that effect Dopamine (DA) in a similar way....will also have similar effects. Dopamamine (DA) is a common neurotransmitter that is targeted by various medications, so these effects may be more prevelant than just for schizophrenics on nueroleptics.
Ok.....I'll stop nerding the thread up.
Feel free to ask about other areas of smoking and etc...and we can talk about that. (It is not my area of study, but interesting none the less)
