Hmm, of course nicotine itself is stimulating, but this makes me wonder if MAO inhibition might be one of the causes for tobacco smokers seemingly being more communicative? When smoking was still allowed in trains, cars were usually split in smoking and non-smoking areas. I always found it fascinating to watch how the different groups behaves if I happened to walk for a while to find a free place. The non-smoking area typically felt dead quiet, almost depressingly. And one you opened the door to the smoking area, pretty relaxed chatting amongst the travelers was the norm.
