Objective(s): To examine prevalence and patterns of non-medical cannabis use, including use among young adults, age of initiation, and levels of dependence; to examine the cannabis retail environment, including the extent to which consumers shift from illicit sources to legal retail sources, and the types of products used, including high potency products; to assess changes in problematic use and risk behaviours, including driving after cannabis use, use in high risk occupational settings, and co-use with other types of psychoactive substances (e.g., opioids, alcohol, tobacco, e-cigarettes); to examine changes in perceptions of risk and social norms; and to evaluate the effectiveness of specific regulatory policies, including consumer awareness and knowledge of product health warnings, exposure to cannabis marketing, exposure to public education campaigns, and cannabis use in public spaces and workplaces.

Project Description: This licence has been issued for the scientific research application No.4964.

The study has five objectives:
1. To examine prevalence and patterns of non-medical cannabis use, including use among young adults, age of initiation, and levels of dependence;
2. To examine the cannabis retail environment, including the extent to which consumers shift from illicit sources to legal retail sources, and the types of products used, including high potency products;
3. To assess changes in problematic use and risk behaviours, including driving after cannabis use, use in high risk occupational settings, and co-use with other types of psychoactive substances (e.g., opioids, alcohol, tobacco, e-cigarettes);
4. To examine changes in perceptions of risk and social norms; and
5. To evaluate the effectiveness of specific regulatory policies, including consumer awareness and knowledge of product health warnings, exposure to cannabis marketing, exposure to public education campaigns, and cannabis use in public spaces and workplaces.

A population-based online survey will be conducted among a total of 1,500 participants (500 in each of the 3 territories) aged 16+. The consent information and online survey will be available in English, French, Inuktitut, and Inuinnaqtun. Please refer to Appendices E and F of this research license application for the consent information and online survey (including technical notes for the survey programmer), respectively, in English. The online survey was used in a small pilot conducted among approximately 350 participants aged 19+ in NWT and Yukon in 2018 (NWT Licence No. 16393), as well as a larger international study conducted among approximately 110,000 participants aged 16+ residing in Canada and the United States over the last 3 years. On average, participants complete the online survey in approximately 25 minutes. Participants will receive $20 e-transfer for completing the online survey in appreciation for their time.

We are aiming to recruit study participants aged 16+ from across NWT using multiple strategies, including online platforms (e.g., social media, online local newspaper advertisements) and local radio announcements, as well as in-person recruitment in Yellowknife, Inuvik, and Hay River. For the in-person recruitment, we are planning to hire a total of 4 local research assistants, 2 in Yellowknife, and 1 in each of Inuvik and Hay River, to help with distributing recruitment materials at local community centres and other public venues in these communities. All in-person recruitment activities will be done in accordance with local COVID-19 safety protocols.

Recruitment will occur for 6 weeks in September to October each year for 3 years (2021, 2022, and 2023). Participants will be invited to complete the online survey conducted in September and October each year for up to 3 years. All data collections will occur online over a period of up to 8 weeks each year.

As we are aiming to recruit study participants across all of NWT, the Department of Health and Social Services and Hotiì ts’eeda advised us to connect with community leaders across NWT prior to submitting the research license application to provide study information and invite feedback. We took a similar approach when applying for a research license for the pilot conducted in NWT and Yukon in 2018 (NWT Licence No. 16393). Please refer to Appendix B of this research license application for the technical report for the pilot conducted in NWT and Yukon in 2018. In the feedback received from the community leaders in NWT and Yukon for the pilot study, we were advised to extend participant recruitment beyond Yellowknife and Whitehorse to smaller communities across the territories, given that cannabis use may differ between capital regions and smaller communities. We have incorporated this feedback in the current proposed study.

Each year of the study, summaries of study findings will be provided via email to the Indigenous community leaders, Hotiì ts’eeda, NWT Chief Public Health Officer, NWT Department of Health and Social Services, and Health Canada. The Principal Investigators will host presentations of the results with territorial partners each year of the study, if requested. In addition, aggregated results will be shared on the project website (www.cannabisproject.ca/territories), in publications, and at conferences. No identifying information will be used in any reports. Of note, Indigenous identity will not be used in any of the analyses; aggregated data on Indigenous identity will only be used to describe the characteristics of the sample.

The fieldwork for this study will be conducted from September 7, 2021 to October 31, 2021.
