CTUMS

Smoking status has been defined to be consistent with the definitions used in other national Health Canada surveys that collect data on tobacco use.

Smoking prevalence: the number of smokers in a specified group, divided by the total population of that group, expressed as a percentage. May also be referred to as the "smoking rate".

Cigarette consumption: the amount reported smoked by either daily or occasional smokers. In this report, consumption is reported only for daily smokers.

Current smoker: includes daily smokers and non-daily smokers (also known as occasional smokers). Determined from the response to the question "At the present time do you smoke cigarettes every day, occasionally, or not at all?"

• Current daily smoker: refers to those who respond "every day" to the question "At the present time do you smoke cigarettes every day, occasionally or not at all?"
• Current non-daily smoker: often referred to as "occasional" smoker, refers to those who respond "Occasionally" to the question "At the present time do you smoke cigarettes every day, occasionally or not at all?"

Former smoker: was not smoking at the time of the interview, however, answered "YES" to the question "Have you smoked at least 100 cigarettes in your life?"

Ever-smokers: current and former smokers combined.

Never-smoker: was not smoking at the time of the interview and answered "NO" to the question "Have you smoked at least 100 cigarettes in your life?"

Non-smokers: former smokers and never-smokers combined.

Quitter percentage: the ratio of the number of former smokers in a specified group divided by the number of ever-smokers in that group.
