Prevalence
the proportion of a group or population reporting the indicated behaviour or outcome, usually expressed as a percentage.
Statistically Significant
the observed relationship between two or more variables is unlikely due to chance alone.
Weighted Results
weighting is the statistical technique used to allow the study sample to be representative of the target population; in other words, any participant's response is weighted so that it represents a specific number of identical responses in the target population.
95% confidence interval
provides a range of values in which the estimated prevalence will fall 95% of the time (i.e., if the survey was repeated 20 times, the results would fall within this range 19 of those times, or 19 times out of 20).
Current smoker
includes daily smokers and occasional smokers, determined from the response to the question "At the present time do you smoke cigarettes every day, occasionally, or not at all?"
Daily smoker
refers to those who respond "everyday" to the question "At the present time do you smoke cigarettes every day, occasionally or not all?"
Occasional smoker
refers to those who respond "occasionally" to the question "At the present time do you smoke cigarettes every day, occasionally or not 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?"
Short term quitter
a former smoker who quit smoking less than one year prior to the survey. Determined by their response to the question, "When did you stop smoking? Was it less than 1 year ago, 1 to 2 years ago, 3 to 5 years ago, or more than 5 years ago?"
Long term quitter
a former smoker who quit smoking a year or more prior to the survey and has not resumed smoking during that time frame. Determined by their response to the question, "When did you stop smoking? Was it less than 1 year ago, 1 to 2 years ago, 3 to 5 years ago, or more than 5 years ago?"
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?"
Ever smokers
current and former smokers combined.
Non-smokers
former smokers and never-smokers combined.
E-Cigarettes
are battery-operated devices that mimic the act and taste of smoking cigarettes but do not contain tobacco. E-cigarettes include vaporizers with e-juice, vape pen, tank, or mod and are available with or without nicotine.
Past-year use
reported use in the 12 months preceding the interview.
Acute effects
possible short-term effects of alcohol use include injuries and overdoses.
Age of initiation
the age at which a person first used alcohol or a drug.
Problematic use
drugs used for reasons other than for prescribed therapeutic purposes including use for the experience, for the feeling they caused, to get high, to feel better (improve mood) or to cope with stress or problems.
Harm
