1.0 Background and Objectives
1.1 Background
Use of marijuana is common in Canada. In 2015, Health Canada’s Canadian Tabacco, Alcohol and Drugs Survey (CTADS) found that 12.3% of respondents 15 years of age and older reported using marijuana in the past year. Past-year use was more common among males (15%) compared to females (10%). 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 five students in grades 7 to 12 reporting past year use in the 2016-2017 Canadian Student Tabacco, Alcohol and Drugs Survey (CSTADS). International data for cannabis from 2013 showed the United States as the leader in lifetime prevalence rates at 43.7%Footnote 1, while Canada followed closely behind at 41.2%Footnote 2, and then the United Kingdom at 29.9%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. In June 2017, the Government of Canada introduced Bill C-45, the Cannabis Act and in 2018 this Bill was passed. Non-medical cannabis legalization and regulation is scheduled to go into force October 17th, 2018.
The legalization and regulation of non-medical 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 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 the knowedge, perceived acceptability and health risks, pattern of recreational use, and information-seeking behaviors. This study found that 58% of respondents reported cannabis use in the past 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.
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. All respondents were asked questions regarding the social acceptability of recreational cannabis use, observations of cannabis use in public, cannabis use by family and friends, use of cannabis in the home and for opinions on cannabis effects, cannabis impairment and driving, and whether cannabis can be habit forming. Respondents that reported using cannabis in the past 12 months were asked detailed questions relating to the frequency, quantity, routes of administration, and forms of cannabis used. They were also asked about the cost of purchasing cannabis and where they typically source the cannabis they use. In addition, they were asked about driving after use, harms and benefits of cannabis use and whether they use cannabis for medical purposes.
1.2 Objectives of the survey
The 2018 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:
- Cannabis use and non-use in Canada;
- Patterns of use (e.g., age of initiation and products used);
- Public concerns related to cannabis, including traffic accidents, drug-impaired driving, drug-related crime; and
- Perceptions of risk and normalization.
1.3 Total expenditure
The total cost of this research was $221,000.00 excluding 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 83 percent mobile phones and 17 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 majors reasons; first, they use their parents’ landline and we have difficulty reaching them; second, if they have left their parent’s house, they most likely use a cell phone rather than a landline.
In total, we called 201,235 phone numbers, and 22,356 people agreed to participate in the survey. Of these calls, 18 percent were conducted in French and 82 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 respondent’s mobile phones via a Short Message Service (SMS). The advantage of SMS survey invitations is that, unlike email invitations, it avoids 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, 80 percent were recruited via SMS, and 20 percent were recruited by email. Of those recruited to the online survey by SMS, 56.6% completed the online survey. Among those sent an email invitation, the completion rate of the online survey was 65.6% 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.
Email reminders were sent 3 days and 6 days after the initial invitation. Once reminders had been sent, Advanis also conducted telephone reminders 3 days after the last reminder to confirm the invite had been received, and corrected 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 invite was triggered automatically.
The average survey length for the questionnaire for those that used cannabis in the past 12 months was 22 minutes, and it was just under 10 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 3 minutes.
The pretest and field dates
The English pretest was conducted on May 15th, 2018. During this pretest, we recruited 184 people by phone, which then translated into 103 completed online surveys. The French pretest was conducted on May 17th with 186 phone interviews completed by the end of the day. The validation of the data was completed the morning of May 18th. 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. The data collection period was from May 15th to July 9th, 2018.
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 hand it off to a programmer who is less familiar with the survey subject matter. Below are the steps followed to ensure the quality of the surveys.
- The surveys were thoroughly pre-tested by Advanis’ project team members as well as by non-team members (non-team members provide “fresh eyes”).
- The online surveys was sent and tested by the representatives of Health Canada (and their designated testers). This allowed Health Canada to ensure skip patterns and survey questions were correctly programmed.
2.3.2 CATI Methodology and quality control
The CATI recruit script was programmed on Advanis’ proprietary CATI platform with no foreseen challenges. Advanis was able to leverage its experience for the survey programming and the reminder process to achieve high quality standards.
- Trained the interviewers to best understand the study’s objectives and to ensure that they are able to pronounce and understand the survey wording.
- Detailed call records are kept by the automated CATI system, and are supplemented by output files to SPSS for productivity analysis (i.e., not subject to human error);
- Screening scripts contained a description of the importance of the research and the importance of respondent participation, serving as a motivator for respondents;
- The recruit scripts were pre-tested for best possible flow;
- Briefing was done on an ongoing basis to ensure that all interviewers are up to date on current information regarding the project;
- Our average interviewer tenure is very strong based on industry standards, resulting in a consistent team of interviewers whose experience and knowledge with the target audience increases quality;
- Advanis’ Quality Assurance team listened to the actual recordings of ten percent of completed surveys and compared the responses to those entered by the interviewer to ensure that responses are properly recorded. This is in addition to the live monitoring done by field supervisors.
- Team Supervisors conduct regular, more formal evaluations with each interviewer, in addition to nightly monitoring of each interviewer on their team.
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:
- Respondents have a unique access code to ensure that only that participant can complete the online survey.
- Extensive internal logic checks are programmed directly into the survey to ensure logical responses.
- Web surveys are implemented using Advanis’ proprietary software (which is designed to handle complicated survey formats).
- Advanis administered a detailed internal test and an external pre-test to ensure that the survey instrument was working as planned.
- We tested the questionnaire in multiple browsers and we emailed a link to our clients so they could do internal testing.
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:
- Time taken to complete the survey (those who completed the survey too quickly are removed)
- Data consistency check (has the respondent answered multiple questions in expected ways)
- Straight-lining tables of responses (checks against respondents who provide the same response to every table)
- And, of course, rigorous checks are completed to ensure the data is accurate and error-free according to the questionnaire logic (skip patterns).
Advanis staff have used the SPSS Statistics Software for 20 years and are very proficient users of the software. All data cleaning performed on a project 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 of this project is Canadians who are 16 years and older. This study includes 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 12%, according to Health Canada data.
Key sub-population variables that required quotas were:
Age (16-19, 20-24 and 25 and older);
Provinces; and
Sex.
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 12,958 responses 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, 12,958 web interviews were conducted during data collection, 2,374 in French and 10,584 in English. The weighting of the final file was based on three variables: region, age, and sex at birth. For the 136 people who were missing a response for sex at birth, gender was used in place of sex at birth for 130 cases, and a random sex was attributed to the other 6 cases. This group will be analyzed separately for analysis purposes. 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 the number of interviews are done 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 a high quality of results. Since it was requested right before launch by Health Canada to give respondents the option to refuse to answer any question, questions were made not required instead of adding an opt-out option to the survey itself. This was the simplest course of action given both time and translation constraints. During data cleaning respondents who were asked the question and refused to provide an answer were recoded to “Prefer not to say”.
A recode was done for 5 cases where the validation in the pretest did not allow a response of 0 in questions q39b and m19b so responses of 1 were given to advance past the question.
Q29 was also recoded in the data as level 1 (I grew my own), if Q28=1 (I grew all the cannabis I used myself). This question (Q29) was skipped in the survey for these cases as it did not make sense to ask it.
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 was done using the same logic for recoding as the 2017 Canadian Cannabis survey, for consistency and comparability of results. The scale used was the same as in the previous phase of the project.
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:
- Provinces and territories
- Age: 16 to 19, 20 to 24, 25 to 34, 35 to 44, 45 to 54, and 55+ or any unaltered grouping of theses ranges (i.e., 16 to 24 or 35 to 54)
- Sex: male or female
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.
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 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 |
Estimate Stability |
*CV= (standard error / coefficient) * 100 where the coefficient is either the regression coefficient or the proportion estimate. |
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 |

MainIntro
In this survey 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 but not synthetic cannabinoids.
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, a concentrate, including hashish, a liquid, or other product for non-medical purposes.
By non-medical purposes we mean recreational (e.g., for enjoyment, pleasure, amusement), socially, for spiritual, lifestyle and other similar non-medical uses.
