Background. Some smokers maintain a low daily smoking rate and do not
appear to be addicted to nicotine (tobacco ''chippers''). In a context
of increasing social and environmental constraints on cigarette smoki
ng, it is of interest to determine the population prevalence and the c
haracteristics of low-rate smoking behavior. Methods. A representative
population survey was used to determine the prevalence and the correl
ates of low-rate smoking (five or less cigarettes a day). A range of s
ociodemographic, contextual, cognitive, and smoking-behavior variables
was examined. Results. Of 697 smokers age 20 years and over who had s
moked for more than 2 years, 8.2% smoked five or less cigarettes a day
; their average age was 39 years, and half were under 35 years of age;
88% had been smoking for 6 or more years; 86% were in the contemplati
on or preparation stages of readiness to quit. The significant indepen
dent predictors of being a low-rate smoker, compared to smoking at a h
igher daily rate, were perceiving quitting as not very difficult, smok
ing the first cigarette of the day more than 30 min after waking, buyi
ng packets of 30 or less cigarettes, and having not been advised by a
doctor to quit. Conclusions. There were few differences between low-ra
te and other smokers on the range of variables that we were able to as
sess in a population survey. Since there is no safe level of cigarette
smoking, medical advice to quit and public-education campaigns could
target low-rate smokers specifically. Such initiatives could make sign
ificant contributions to reducing overall smoking prevalence. (C) 1995
