No Smoking! Workplace Smoking Restrictions and Effects on Smoking Behaviour

John A. Stevenson, MA and Judy Snider, MSc. Tobacco Control Program, Health Canada, 123 Slater Street, MacDonald Bluilding, 7th Floor, Ottawa, ON K1A 0K9, Canada

Objective: To document changes in smoking behaviour which may be related to the implementation of smoking restrictions in the workplace in Canada.

Methods: The Canadian Tobacco Use Monitoring Survey (CTUMS) is an ongoing random digit dialing telephone survey of over 20,000 Canadians 15 years and older. Employed daily smokers were defined as current daily smokers 15 + years who worked at a job or a business at any time during the last 12 months.

Results: In 2004, approximately 70% of respondents reported working in the last 12 months and, of these, 91% reported some kind of smoking restriction in the workplace with 71% identifying that their workplace was completely smoke-free (up from 40% in 1994). Complete workplace smoking restrictions varied among the provinces.

Differences between the numbers of cigarettes smoked per day varied according to the level of smoking restrictions in the workplace. Fewer cigarettes were smoked per day where there was a complete ban (14.2 cigarettes) compared to where there was no ban (16.5 cigarettes).

There appears to be an association between workplace smoking restrictions and smoking behaviour as the 2004 data suggests that full workplace smoking restrictions may reduce cigarette consumption amongst daily smokers.

Results from CTUMS 2005 wave 1 (February - June) examining opinions on smoking in the workplace will also be presented.
