Commentary. monitoring tobacco use in canada: the need for a surveillance strategy

Smoking behaviour has been monitored nationally through population surveys for 35 years in Canada, but these surveys have not been as consistent or rigorous as the magnitude of the smoking problem demands. Inconsistent methods and irregular survey intervals are just two of the characteristics that have made it difficult to know exactly how smoking is changing. Further, an absence of routine data on tobacco control policies (other than the price of cigarettes) has hampered understanding of the determinants of changing prevalence. The advent of two survey series--Canadian Tobacco Use Monitoring Survey (CTUMS) and Canadian Community Health Survey (CCHS) promises to change this situation for the better. We suggest that both are critical elements of a national smoking surveillance system and that, with a commitment to CTUMS in particular, Health Canada could set a new international standard for surveillance.
