1.0 Background and Objectives

1.1 Background

Use of cannabis is common in Canada. In 2017, Health Canada's Canadian Tobacco, Alcohol and Drugs Survey (CTADS) found that 15% 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 to 24 years old were significantly more likely to use cannabis in past 12 months than those 25 years of age or older. Use is also common in students, with almost one in six students in grades 7 to 12 reporting past year use in the 2016-2017 Canadian Student Tobacco, Alcohol and Drugs Survey (CSTADS). International data for cannabis from 2017 showed the United States has alifetime prevalence rate at 45.2% Footnote 1, while Canada has a similar prevalance rate of 46.6% Footnote 2. Prevalence rates for past year cannabis use were highest in North America (13.8%) when compared to other regions (Oceania (10.9%); Africa (6.4%); Europe (5.4%); South America (3.5%); Asia (1.8%)) around the world Footnote 3.

In the 2015 Speech from the Throne, the Government of Canada committed to legalizing, regulating, and restricting access to cannabis. In 2016, the Government's Task Force on Cannabis 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. In 2017, the Government of Canada introduced Bill C-45, An Act respecting cannabis and designed to amend the Controlled Drugs and Substances Act, the Criminal Code and other Acts. 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 the subject of 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 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 Behavior 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 that 22% reported use in the past 12 months. Among those who did not report use in the past 12 months, 85% felt they were unlikely to use cannabis once it becomes legal. The subsequent iterations of the Canadian Cannabis Survey will continue to examine in more depth patterns of use, such as the quantities used and medical use; the cannabis market, such as sources and pricing; and issues of public safety, such as impaired driving.

In 2017, the first cycle of the Canadian Cannabis Survey (CCS) was completed and collected data from 9,215 people 16 years of age and older. It examined, in more depth, 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. The 2018 Canadian Cannabis Survey aimed to gather additional data, such as changes to willingness to publicly report cannabis use if legal; perceived risk of using cannabis in various ways; expected sources of cannabis once it is legal; absenteeism from school and work as a result of cannabis use; and receiving treatment or counseling for cannabis use. The 2018 Canadian Cannabis Survey also asked about maternal use during pregnancy and while breastfeeding. In 2018, Health Canada conducted the second cycle of the CCS (administered by Advanis). It was in the field from May 15, 2018 to July 9, 2018 and collected data from 12,958 people 16 years of age and older. Of the responses received, 3,395 responses were from people who indicated that they had used cannabis in the past 12 months for either non-medical or medical purposes. In 2019, the third cycle was conducted, collecting 12,023 completed surveys from people 16 years of age and older. All respondents were asked questions regarding cannabis use and non-use in Canada; patterns of use (e.g., age of initiation, frequency of use, quantities and products used); public concerns related to cannabis (including problematic use and drug-impaired driving); perception of risk and normalization; and use of cannabis for medical purposes and reasons for this use.

1.2 Objectives of the Survey

The 2019 Canadian Cannabis Survey aimed to gather additional data. It wanted to examine in more depth patterns of use, such as the quantities used and medical use; the cannabis market, such as sources and pricing; and issues of public safety, such as impaired driving.

In conducting this research, Health Canada's objective was to collect information on the following:

1.3 Total Expenditure

The total cost of this research was $249,730.00 including HST.

2.0 Sampling

2.1 The General Approach

The approach used was a two-step recruitment process where respondents were first recruited by telephone (both land-line and mobile) using a short battery of screener questions approved by Health Canada. 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 96 percent mobile phones and 4 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 two major reasons; first, they use their parents' landline and we have difficulty reaching them; second, if they have left their parents' house, they most likely use a cell phone rather than a landline.

In total, we called 230,038 phone numbers, and 21,325 people agreed to participate in the survey. Of these calls, 17 percent were conducted in French and 83 percent were conducted in English. The response rate calculation is presented in Appendix A.

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, 86 percent were recruited via SMS, and 14 percent were recruited by email. Of those recruited to the online survey by SMS, 57.4% completed the online survey. Among those sent an email invitation, the completion rate of the online survey was 50.0% percent.

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 dialled by someone in the call centre, the calling record was automatically displayed to an interviewer.

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, Advanis also conducted telephone reminders at least 3 days after the last reminder to confirm the invite had been received, and to correct email addresses if necessary. During these calls (only made once), voicemail messages were left reminding the respondents that the survey was still open and a final invitation was triggered automatically.

The average survey length for those that used cannabis in the past 12 months was 24 minutes, and it was 12 minutes on average for those that did not use cannabis in the past 12 months. We need to keep in mind that, 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 over 2 minutes.

2.2 The Pretest and Field Dates

The pretest was conducted on April 4th, 2019. During this pretest, we recruited 425 people by phone, 368 in English and 56 in French. This translated into 80 completed online surveys, 71 English and 9 French. The validation of the data was completed the morning of April 5th. This validation included respondents that had used cannabis in the past 12 months, as well as those that had not, to ensure that all questions were tested. No changes were made to the survey following the pretest, although one case was removed from the data due to comments that they had answered the survey incorrectly. The data collection period was from April 4th to June 17th, 2019.

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 for 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 given and listen to the respondent.

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 study included both those that had used cannabis and those that had not. A "person that uses cannabis" is someone who has used cannabis in the last 12 months. The expected incidence of cannabis use in the past 12 months in the general population is 15%, according to Health Canada data.

Key sub-population variables that required quotas were:

The sample consisted of a core sample of 10,000 Canadians aged 16 and older (those that use cannabis and those that do not). In the end, we gathered 12,023 responses (10,163 in English and 1,860 in French) in order to reach all of our quotas. Table 1 presents the results for the entire data collection versus the quota for the base sample.

3.0 Weighting

3.1 The Weighting Approach

Overall, 12,023 web interviews were conducted during data collection. The weighting of the final file was based on three variables: region, age, and sex at birth. For the 220 people who were missing a response for sex at birth, gender was used in place of sex at birth for 117 cases, and no weights were attributed to the 103 other cases (no sex or gender identified). The cases where a weight could not be attrbuted were excluded from national estimates but remain in the data set. The population sizes are based on the latest Statistics Canada census results published, the 2016 Census. Since the value for the 16 to 19 age category wasn't available (only 15 to 19 is provided), we reduced the 15 to 19 year category by 1/5 of the size to reflect the best estimate of the number of 16 to 19 year olds. See section 4.2 for guidelines on the limitation of analysis with the weights.

3.2 The Design Effect Calculation

Introducing weighting generates a design effect that can be attributed to weight variation. This effect increases the sampling error in comparison to the random sampling without weighting.

The following table presents the design effect (the effect of the sampling plan on the statistical power of the sample) for each region separately as well as for the entire sample. Also, this table shows the size of an "efficient" sample, which corresponds to the size of the random sample which would have the same precision degree. For the total sample, the variation of the sampling fractions comes from the fact that a certain number of interviews were completed in each region regardless of their size.

4.0 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 2018 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, which was required). During data cleaning, respondents who refused to provide an answer were recoded to "Prefer not to say".

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. For this recoding of scales into a metric value, the recoding used the same logic as in the 2018 Canadian Cannabis Survey, for consistency and comparability of results. The scale used was the same as in the previous phase of the project, except for the cannabis oil for oral use, which offered different options than in previous cycles. The recode scale used for this was provided by Health Canada.

A recode was completed for four survey questions based on the "Other, please specify" responses. These questions asked about the type of vehicle respondents drove after partaking in substances (Q52a, Q53a, Q54a and Q55a). In reviewing the data, it was found that the response level in the survey said "car" and respondents entered responses of "truck" and "SUV" in the "Other, please specify". These were recoded back into the "car" level after confirmation was received from 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 coding guide was created for answers that had sufficient numbers of mentions to be added in as a new response level. Specific verbatim themes that did not have a sufficient number of mentions were left in the "other" category.

4.2 Guidelines for the Analysis and the 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 study, the basic sociodemographic information that should be used in 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 are not aligned with these specified categories.

In the provided data file, the variable to be used to weight the data is called "weight". In this case, it was decided to project to the total population, around 28 million Canadian residents (per the 2016 Statistics Canada Census).

Any results with an unweighted base of 30 respondents or fewer should not be reported on, due to statistical robustness. Results with more than 30 but fewer than 50 respondents should be interpreted with caution, and considered as directional guidelines. Results based on 50 or more respondents have not been noted in any way. The reason for suppressing results with small 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, the following guidelines for data suppression related to coefficients of variation (CV) should be used when reporting results:

CV range Footnote 4 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
