Does the reaction of abstaining smokers to the smell of other people's cigarettes predict relapse?
OBJECTIVE
Recent ex-smokers report a range of reactions to other people's cigarette smoke. We examined the hypothesis that those who find the smell of smoke pleasant and tempting are more likely to relapse than those who have a neutral or even negative reaction to it.


METHODS
A total of 1110 consecutive patients who attended for smoking cessation treatment and achieved at least 1 week of validated abstinence provided weekly ratings of their reactions to other people's cigarette smoke together with routine baseline measures and weekly ratings of withdrawal discomfort [measured on the Mood and Physical Symptom Scale (MPPS)].


RESULTS
Twenty-three per cent of the sample found the smell of other people's cigarette smoke during their first week of abstinence pleasant, and 54% found it tempting. There was only a modest correlation between the two variables. Finding the smoke pleasant was not related to smoking status in the following week, but finding the smoke tempting predicted relapse. Ratings of temptation were related to the severity of withdrawal discomfort and to dependence. Entering MPPS ratings of urges to smoke in the given week into regression analysis resulted in the general urges to smoke, rather than urges elicited by other people's smoke, becoming a significant predictor of smoking status in the following week. In patients who maintained continuous abstinence throughout 4 weeks of treatment the pleasantness ratings remained stable, while the ratings of temptation steadily decreased.


CONCLUSIONS
In abstaining smokers, the like or dislike of other people's smoke is not related to relapse. The temptation to smoke elicited by other people's smoke is related to outcome, but only as an indicator of a general 'temptation threshold'. Patients who find other people's smoke tempting can be reassured that this reaction will gradually decrease.
