1. Background and Objectives

The use of cannabis is common in Canada. In 2019, Health Canada's Canadian Alcohol and Drugs Survey (CADS) found that 21% of respondents 15 years of age and older reported using cannabis in the past year, with males reporting use more often than females. Canadians 15-24 years old were significantly more likely to use cannabis in the past 12 months than those 25 years of age and older. Cannabis use is also common among students, with 18% of students in grades 7-12 reporting past year use in the 2021/2022 Canadian Student Tobacco, Alcohol and Drugs Survey (CSTADS). International data for cannabis from 2021 shows that the United States had a lifetime prevalence rate of 50.0%Footnote 1, while Canada had a prevalence rate of 41.7%Footnote 2. Prevalence rates for past year cannabis use were highest in North America (14.6%) when compared to other regions (Australia and New Zealand (10.6%); West and Central Africa (9.3%); Europe (5.4%); Asia (1.9%)) around the world.Footnote 3

In the 2015 Speech from the Throne, the Government of Canada committed to legalizing, regulating, and restricting access to marijuana. In 2016, the Government's Task Force on Marijuana Legalization and Regulation issued a discussion paper entitled "Toward the legalization, regulation and restriction of access to marijuana" that initiated wider consultations and dialogue regarding its intention in this area (see: http://healthycanadians.gc.ca/health-system-systeme-sante/consultations/legalization-marijuana-legalisation/alt/legalization-marijuana-legalisation-eng.pdf for more information). In 2017, Bill C-45, An Act respecting cannabis and to amend the Controlled Drugs and Substances Act, the Criminal Code and other Acts, was introduced in the House of Commons. Implementation of the new Cannabis Act occurred in October 2018, creating a regulated legal market for non-medical cannabis for adults in Canada.

The legalization and regulation of cannabis in Canada has also prompted a policy and scientific requirement to collect new comprehensive data on cannabis use and non-use, including indicators in the areas of health, public safety, and markets. New research on cannabis use is helping the government to better evaluate the possible impacts associated with its legalization, regulation, and restriction. In May and June 2016, Health Canada conducted the Baseline Survey on Awareness, Knowledge and Behaviour Associated with Recreational Use of Marijuana (administered by Ekos Research Associates). This study examined knowledge, perceived acceptability and health risks, patterns of recreational use, and information-seeking behaviours. This study found that 58% of respondents reported cannabis use in their lifetime and 22% reported use in the past 12 months.

The Canadian Cannabis Survey (CCS) was first conducted in 2017 and is an annual cross-sectional survey completed online. The Canadian Cannabis Survey examines patterns of use, such as the quantities of cannabis consumed and the use of cannabis for medical purposes; the cannabis market, such as sources of cannabis and pricing; and issues of public safety, such as impaired driving, in more depth than other substance use surveys. The CCS is reviewed each year to ensure content is up to date. In additional to its original aims, the survey also gathers data on changes to willingness to publicly report cannabis use since legalization; exposure to education campaigns, public health or safety messages; respondents' usual source of cannabis products since the Cannabis Act came into effect; relative levels of THC and CBD in the cannabis products people use; exposure to second-hand cannabis smoke/vapour; home growing and the preparation of edibles in the home; more details on products and devices used when vapourizing cannabis; frequency of obtaining cannabis from legal and illegal sources; and changes in cannabis use due to the COVID-19 pandemic. In 2023, questions related to adverse reactions were also included. In addition, the survey was redesigned to integrate most questions that were repeated in both the non-medical and medical cannabis use sections of previous cycles to create single questions asked of all those who used cannabis. This was done to reduce response burden and get more fulsome data from those who use cannabis for medical purposes. Of the responses that were received, approximately 3,700 responses were from people who indicated that they had used cannabis in the past 12 months for either non-medical or medical purposes.

Achieving the research objectives will support Health Canada's ability to assess the health risks or harms of cannabis among individuals who use cannabis and/or the community (dependence, harms and risk factors among at-risk populations). The results will be used to support policy development and to evaluate the impacts of cannabis legalization and regulation in the post-legalization period.

1.1 Objectives of the Survey

The 2023 Canadian Cannabis Survey aimed to gather additional information to track changes in data collected from the 2017 through 2022 surveys. The objectives of the 2023 survey were to collect information on the following:

1.2 Total Expenditure

The total expenditure of this research was $294,838.65 including taxes.

2. Sampling

2.1 The General Approach

The approach used was a two-step recruitment process where respondents were first recruited by telephone (both landline and mobile) using a short battery of screener questions approved by Health Canada, consistent with previous cycles. Respondents who completed the screener questions and qualified for the survey were then sent a link to the online survey, either by email or SMS, depending on their preference. Respondents were recruited from lists of random telephone numbers (RDD) that Advanis verified were in service. The distribution of phone numbers was approximately 95 percent mobile phones and 5 percent landline numbers.

The rationale for using a higher volume of cell phone than landline numbers came from the requirement of oversampling youth aged 16 to 24 years old. From previous experience, we know that this group is very hard to reach by conventional landline for three major reasons; first, they use their parents' landline and we have difficulty reaching them; second, if they have left their parents' house, they are more likely use a cell phone rather than a landline; and third, a large proportion of Canada has become cord-cutters who no longer have a landline phone.

In total, we called 367,900 phone numbers, and 36,483 people agreed to participate in the survey. Of these calls, 13 percent were conducted in French, and 87 percent were conducted in English. The response rate achieved in 2023 was 12.8%. The response rate calculation is presented in Appendix B.

During the computer assisted telephone interviews (CATI) recruit, Advanis requested permission to send the survey link to respondents' mobile phones via a Short Message Service (SMS). The advantage of SMS survey invitations are that, unlike email invitations, they avoid issues with incorrect email addresses and spam filtering. If the recruited respondent did not have a smartphone, or preferred email, survey links were sent via email. Of the respondents who completed the CATI screener, 97 percent were recruited via SMS, and 3 percent were recruited by email. Of those recruited to the online survey by SMS, 32.3% completed the online survey. Among those sent an email invitation, the completion rate of the online survey was 43.7%.

To increase the response rate, inbound calling was allowed and directed to interviewers trained on the survey. If the potential respondent called from the phone that was initially dialed by someone in the call centre, the calling record was automatically displayed to an interviewer. In 2023, there were over 28,000 inbound calls, and just over 2,600 respondents were recruited on an inbound call.

Invite reminders were sent 3 days and 6 days after the initial invitation. A third SMS/email reminder was sent to those flagged as being under 25 years of age an additional 3 days later, in an attempt to boost response rates. Once SMS/email reminders had been sent, towards the end of field, an additional "final" reminder was sent noting to respondents that it would be their last reminder to complete the survey.

The average survey length for those who used cannabis in the past 12 months was 25 minutes, and it was 14 minutes on average for those who did not use cannabis in the past 12 months. Notably, during an online survey, the time elapsed doesn't necessarily align perfectly with survey duration since respondents may not always complete the survey all at once. As for the duration of the recruitment interviews, the average length was just under 2 minutes.

2.2 The Pretest and Field Dates

The pretest was conducted on May 2nd, 2023 in both English and French. During this pretest, we recruited 239 people by phone, 112 in English and 127 in French. This translated into 38 completed online surveys, 15 in English and 23 in French. The validation of the data was completed the morning of May 3rd. This validation included respondents who had used cannabis in the past 12 months, as well as those who had not, to ensure that all questions were tested. In reviewing the pretest data, no changes were suggested or made to the survey. Since no changes were made, all pretest cases are included in the final analysis. The data collection period was from May 2nd to July 20th, 2023.

2.3 Quality Control

2.3.1 - Quality Control in Survey Programming

Advanis utilizes technology to maximize quality control in survey programming. Having developed a proprietary survey engine tool, Advanis professionals are able to design and program a survey in a browser-based environment, eliminating the need to involve a programmer who is less familiar with the survey subject matter. Below are the steps followed to ensure the quality of the survey:

2.3.2 - CATI Methodology and Quality Control

The CATI recruit script was programmed on Advanis' proprietary CATI platform with no unforeseen challenges. Advanis was able to leverage its experience with the survey programming and the reminder process to achieve high quality standards.

Advanis implemented the following to ensure the highest quality data collection:

To ensure high interview quality, our interviewers are trained to use various interviewing techniques. As well as maintaining a professional attitude, our interviewers must also be convincing, read word-for-word, take notes, probe deeper on semi-open and open questions, systematically confirm the information provided and listen to the respondents.

2.3.3 - Web Methodology and Quality Control

All Advanis Web surveys are hosted internally by Advanis, and we employ a rigorous and stringent set of data collection control mechanisms to ensure the highest quality for the data collected, including:

2.3.4 - Quality Control in Data Handling and Reporting

For all of the data collected, Advanis develops rules to check the validity of the data. These rules include items such as:

Advanis staff have used the SPSS Statistics Software for over 20 years and are very proficient users of the software. All data cleaning performed on projects are outlined in syntax files with intermediate data files saved throughout the process. This ensures that the original raw data file is never overwritten, and that if an error is discovered in our code, we can quickly and easily rerun the syntax to produce a new data file. Individuals developing code incorporate internal checks in their code (e.g., crosstabs) to ensure the syntax had the desired effect. In addition, all syntax is reviewed by another team member or technical specialist for accuracy.

2.4 Sampling Plan and Data Collection

The target audience for this project was Canadians who are 16 years and older. This survey included both those who had used cannabis and those who had not. A "person that uses cannabis" is someone who has used cannabis in the last 12 months for non-medical or medical purposes. The expected incidence of cannabis use in the past 12 months in the general population is 21%, according to Health Canada data.

Key sub-population variables that required quotas were:

The sample consisted of a core sample of 12,000 Canadians aged 16 and older (those who use cannabis and those who do not). In the end, we gathered 12,024 responses (9,743 in English and 2,281 in French) to reach the quotas. Table 1 presents the results for the entire data collection versus the quota for the base sample.

3. Weighting

Overall, 12,024 web interviews were conducted during data collection and 334 were then removed for a non-response or incorrect response when asked the current month during survey completion. This resulted a final sample of 11,690 interviews. The weighting of the final file was based on three variables: region, age, and sex at birth. In 2023, the sex at birth question was required for all respondents so that all cases could be included in the analysis. The population sizes are based on the latest Statistics Canada census results published in the 2021 Census. See section 4.2 for guidelines on the limitation of analysis with the weights. See Appendix A for the table of weights.

3.1 The Design Effect Calculation

The sample method used in a survey can have an effect in the precision of survey estimates when it is not possible to perform simple random sampling (SRS) with a 100% response rate. This effect is known as the design effect, a constant that can be applied to survey estimators to approximate those obtained under SRS.

The following table provides the design effect for each region as well as for the entire country. This table also shows the size of the "effective" sample size, an estimate of the sample size that would have been required under SRS to achieve the same level of precision.

The difference in effective sample size between the sum of all regions and Canada is due to quotas being used to obtain a minimum of responses for each region instead of proportional sampling.

4. Data Cleaning and Guidelines for Analysis and Release

4.1 Data Cleaning and Coding

After the data collection was completed, data cleaning was performed to ensure high quality results. As was done in the 2022 survey, questions were made voluntary (not required) instead of adding an opt-out option. This was to allow respondents to advance past any questions they did not wish to answer (with the exception of age and sex at birth, and province/territory which were required to create survey weights). In 2023, an opt-out option was added for the remaining socio-demographic questions (i.e., respondents could select 'Prefer not to say' for items such as their highest level of education and household income). During data cleaning, respondents who refused to provide an answer were recoded to "Prefer not to say".

In 2023, the survey was offered in both a mobile friendly platform and a WCAG 2.0 compliant platform online. Due to some of the requirements for WCAG 2.0, not all question types that are used on the mobile friendly platform are available as they do not function correctly with a screen reader. Accommodations were made to adjust the questions to be asked in a slightly different manner in the WCAG version; for example, the detailed scales used for questions on quantities of cannabis consumed could not be read by a screen reader and would have drastically increased survey length. For the WCAG version of the questions, respondents were asked to type in the quantity they used as well as to indicate their unit of consumption (e.g., mg, g). These variables were then back coded in the data into the scale versions of the questions. Less than 2% of respondents completed the survey using the WCAG platform.

The next step was to perform any necessary data coding. A detailed scale was used to describe quantities across the survey. Once data collection was completed, these scales were transformed into metric questions for ease of analysis. The metric question type simplifies the analysis by easily providing measures of mean, median, etc. the recoding used the same logic as in previous iterations of the Canadian Cannabis Survey, for consistency and comparability of results. The scale used was the same as in the previous phases of the project. The recode scale used for this was provided by Health Canada.

A review of open-ended responses was also performed as part of the data cleaning. Any "other" responses were recoded into existing categories when appropriate. A new "other" code was derived whenever the other bucket surpassed 10 responses.

4.2 Guidelines for the analysis and use of weights

When doing an analysis, it is important to align the analysis plan with the weighting scheme. The weights adjust the data to better reflect the population based on parameters that have been chosen to maximize the level of detail without creating distortions due to extreme weights (an extreme weight will occur when a population group is represented by a proportionally smaller subset of respondents compared to other population groups, thus introducing an important risk of bias due to their specific profile).

For this survey, the basic sociodemographic information that should be used in the analysis of results are:

Using age groupings other than the ones described above for these sociodemographic categories could potentially produce distorted data. As these results would be inaccurate based on how the weights were calculated, we strongly advise not to report any results that do not align with these specified categories.

In the provided data file, the variable to be used to weight the data is called "weight6". In this case, it was decided to project to the total population, around 31 million Canadian residents that are 16 years old or older (per the 2021 Statistics Canada Census).

Any results with an unweighted cell size (numerator) of less than 10 respondents or an unweighted base (denominator) of less than 50 should not be reported on, due to statistical robustness. Any results with an unweighted base (denominator) of more than 49 but less than 100 should be identified and a statement regarding the small sample size should accompany these estimates. The reason for suppressing results with small cell and base sizes is due to the increased coefficient of variation and, hence, there are larger confidence intervals around results with smaller bases.

For all estimates based on cell sizes of 10 or more, the following guidelines for data suppression related to coefficients of variation (CV) should be used when reporting results:

CVFootnote 5 range Estimate Stability
0 – 16.5 Acceptable, the estimate stable
16.6 – 33.3 Marginal, the estimate has moderate sampling variability and should be interpreted with caution
>33.3 Unacceptable, the estimate is unstable and should be suppressed

Thank you for completing the survey to this point. You are almost done. You indicated that you have used cannabis for medical purposes. We have a few more questions specific to your use of cannabis for medical purposes.

In this series of questions when we use the term cannabis, this includes marijuana (e.g., weed, pot), hashish, hash oil or any other products made from the cannabis plant. This includes products containing THC, CBD or any other cannabinoids (e.g., CBN, CBG, delta 8 THC).

When we ask about use, this includes using cannabis in its dry form or when mixed or processed into another product such as an edible, concentrate, liquid, or other product for medical purposes.

By medical purposes we mean used to treat a disease/disorder or to improve symptoms.

Prior to the legalization and regulation of cannabis for adults on October 17, 2018 if an individual wanted to access cannabis for medical purposes, they would have needed to seek authorization from their health care provider and then register with either Health Canada to grow their own cannabis or register with a licensed medical seller online to order cannabis products directly from them. Since cannabis is legal for adults, there are many different ways for people to access cannabis that do not require a medical document from a health care practitioner first, such as purchasing from a legal storefront or growing small quantities at home.
