I'm not sure how culturally-specific this is, but as a foreigner living in France, I notice the majority of smokers I meet are those who smoke exclusively while drinking. So to that extent, they appear to have sufficient will-power to resist most of the time, but the lowered inhibitions and the mental association between alcohol and smoke I guess are overwhelming. I wonder what the tangible negative effects are of smoking 4-5 cigarettes a week like this compared to 4-5 a day? I also wonder to what extent this is a French phenomenon.
