Smoking in Ontario, 1991 to 1996.

Surveys by the Addiction Research Foundation of Ontario have produced annual estimates on smoking prevalence since 1991. This report describes the three series of telephone surveys from which these data are drawn as well as future plans to monitor tobacco use in Ontario. In addition to provision of updated descriptive results, the methodology and limitations of the data are discussed. Prevalence data for 1996 are presented from the Ontario Drug Monitor, a telephone survey of Ontario adults (n = 2721). The overall prevalence of smoking in Ontario was 27% (95% confidence interval: 25% to 29%); 23% smoked daily (95% confidence interval: 21% to 25%). There is no evidence of any decline in the prevalence of smoking since 1991, and no sex differences were found in smoking prevalence. Future reports will update trend data and provide robust regional estimates.
