What quitting methods are Canadian smokers trying? And how successful are they?
Statistics Canada has provided new data to help answer these questions. The 2023 and 2024 waves of the Canadian Community Health Survey (CCHS) included questions on the quit methods recently used by smokers.
These results have not yet been published on government web-sites, but they can be found in aggregate form in the Data Dictionaries which Statistics Canada makes available. These can be downloaded here: CCHS 2023 and CCHS 2024, with the data assembled on a fact sheet. More information about the CCHS can be found below and elsewhere.
The survey results indicate that:
- One-half of Canadian smokers have made an unsuccessful quit attempt in the past year
- Two-thirds of those who try to quit do so without using any cessation aids or methods
- The vast majority of quit attempts are unsuccessful (85%)
- Failure rates are essentially the same for most popular products and methods (going it alone, NRT, vaping products). Cutting down may be associated with greater chance of failure.
- Only a small number of smokers use the nicotine pouch or internet programs in their quit attempts, and the survey found few or no individuals who had done so successfully.
Each person who said they had smoked in the last month was asked "In the past 12 months, did you stop smoking for at least 24 hours because you were trying to cut back or quit?"
Of the estimated 3.6 million Canadian smokers in 2023, 1.8 million had made a failed quit attempt in the previous 12 months (51%). Of the estimated 3.6 million smokers last year, 1.8 million had unsuccessfully tried to quit at least once (54%). This question was asked of all people people who said they had smoked in the past month, including those who had not yet smoked 100 cigarettes and who are usually not included in estimates of smoking prevalence. (Variable CSS_41)
As evidenced by the fact that this question was only asked of people who were smoking at the time of the interview, these attempts were unsuccessful.
Successful quit attempts were identified elsewhere in the survey (Variables SPU_10 and SPU_25). Those who were identified as having smoked in the past were asked how long ago they had quit. An estimated 429,500 had quit smoking in the past 12 months in 2023 and 414,500 in 2024. Included in these results are people who smoked fewer than 100 cigarettes before they quit.
Most quit attempts (63%) are made without any aids or methods
The CCHS asked about the stop smoking methods used both by smokers who had tried and failed to quit and those who had stopped smoking in the past 12 months. (Variables SPU_40 and SPU_45)
Eight potential quitting methods were identified in 2023. These were: (a) nicotine replacement products, (b) smoking cessation medications, (c) internet-based programs or apps, (d) vaping devices or e-cigarettes, (e) making a deal with a friend or your family, (f) reducing the number of cigarettes, (g) trying to quit smoking on your own, or (h) an ‘other’ method. People could identify the use of more than one method. An additional method (tobacco-free nicotine pouches) was added to the questionnaire in 2024. These nicotine products were authorized for sale in Canada in the summer of 2023, and were widely available throughout 2024.
The yearly average of these responses is shown below (results for each survey year are provided in the downloadable data sheet).
Two-in-three Canadians (63%) report that they tried to quit smoking on their own, and almost half of smokers (45%) said they used the self-help method of cutting down.
The most commonly used commercial stop smoking aids (NRT or vaping products) were used by one-third of those making a past-year quit attempts. Smoking cessation medications and "other" unspecified methods were used by one-tenth of such respondents, and other products and services (pouches and internet apps) were used by one-twentieth.
No matter the method or product, the vast majority of quit attempts fail.
This survey is not designed to assess whether a quit attempt has been successful, and the results cannot be converted into a measure of quitting success. The survey does allow for an estimate of the minimum failure rate of quit attempts.
Modern clinical trials of stop smoking methods do not generally rely solely on self-reported behaviour, and confirm smoking status with physical or biological tests and use standard time periods to measure quitting success, such as 3- or 6-month abstinence. The CCHS do not provide such measures, and those who identify as recently-quit former smokers would include individuals with varying lengths of abstinence. Some could have had their last cigarette only a few days prior to the interview, and others might have quit smoking up to 12 months earlier.
The CCHS can be used to provide estimates of unsuccessful quit attempts Those who say that they have tried to quit in the past year but also say they are smoking at the time they are interviewed have tautologically failed, no matter how long their quit attempt lasted, although some may have been abstinent for longer than the 6 months often used in clinical trials.
The above chart uses "failure rate" to mean the proportion of smokers who have made a quit attempt in the past 12 months and who say they are still smoking when interviewed. Overall, quit attempts using any of the methods failed 8 times out of 10, with failure rates ranging from 79% to 96%.
Vaping products yield little or no improvement over traditional methods (but carry higher risks)
From this population survey, smokers who use e-cigarettes are little or no more successful than those who used no cessation aid or who used conventional NRT: The aggregate failure rate for these three methods differ by only a percentage point
More than four in five quit attempts using a vaping product did not lead to success. Further analysis of this data (by those with access to the Master Files) could assess whether those failed efforts are associated with the increased risk of dual use, and whether those who succeeded are exposed to the risks of long-term vaping
These results do not suggest cutting down on the number of cigarettes is effective as a quit method.
Almost one half (45%) of past-year quit attempts involved reducing the number of cigarettes smoked. Cutting down is a method still promoted by the Ontario government, Health Canada and others.
These survey results suggest that reducing to quit may be associated with a greater risk of failure. Those who reported a quit attempt using this strategy failed almost all the time (96%). Access to the Master File or PUMF file is needed to establish whether these differences are statistically significant and how the use of more than one quit method affects the results.
Because these quit methods are not randomly assigned, the self-selection of methods is a consideration (i.e. those who reduce to quit may be inherently more challenged in quitting).
Very few Canadians used nicotine pouches - and too few succeeded with this method to provide a statistically reliable estimate.
One brand of tobacco-free nicotine pouches (Zonnic) was approved for sale in the summer of 2023 and by January 2024 this brand was widely available across Canada, although sales were limited to pharmacies by late summer 2024. The CCSH began including questions on tobacco-free these products in 2024, with the question phrased in a way that would include the use of authorized and unauthorized pouches.
The survey estimates that 107,500 smokers used a nicotine pouch in a failed quit attempt. However, when they asked the same question of Canadians whose quitting attempts had not failed, they were unable to find more than 25 individuals who had used these products.
These results suggest that quitting attempts do not explain the size of the nicotine pouch market in Canada, and that unintended use is very high. There are no official reports of legal sales, but Imperial Tobacco identifies that these products are sold in 9,000+ pharmacies across Canada. That company also claims that in addition to the (unstated) volume of its legally-sold pouches, "500 million illegal pouches were sold" in Canada last year.
The Canadian Community Health Survey
The Canadian Community Health Survey is Statistics Canada’s largest national survey collecting information related to health status. The survey began in 2001 and has been conducted annually since 2007. In 2023 and 2024 the survey was restricted to individuals 18 years of age or over. The number of respondents in each of those years was 51,600 and 48,300, respectively. More information on the survey can be found here.
Statistics Canada publishes some results from the survey in a number of tables. Examples include Health indicators by visible minority and selected sociodemographic characteristics; Health characteristics, two-year period estimates. The survey estimates that there were 3.56 million Canadians over the age of 18 who had smoked at least once in the past month in 2023 and 3.61 million in 2024.
The Data Dictionaries provide aggregated results, and do not reveal differences by age, sex, income, mental health or other important determinants of smoking behaviour. Nor do they allow for statistical tests to compare associations. Such analyses can only be done using either the CCHS Master Files, which are available to researchers based in government or universities, or the public use PUMF files which are typically not released for several years after survey completion.
