  • 1. Wastewater-based estimates of cannabis and drug use in Canada: Analytical methods and supplementary information
    Articles and reports: 13-605-X201900100011
    Description:

    This document is a supplement to The Daily article, Wastewater-based estimates of cannabis and drug use in Canada: Pilot-Test Results (citation). It describes the data analysis supporting the results of the article, including the statistical testing and the treatment of outliers and missing data. Additionally, for each of the parameters required to estimate drug consumption, the document provides the values and uncertainty that were used and references to the literature supporting those values.

  • 2. Wastewater-based Estimates of Cannabis and Drug Use in Canada: Pilot test Detailed Results
    Articles and reports: 11-621-M2019004
    Description:

    Legalization of cannabis production, sale, and use in Canada on October 17, 2018 serves as the context for the implementation of the largest wastewater-based epidemiology (WBE) pilot test conducted to date in North America (covering 8.4 million people) and the first by a national statistical agency. Wastewater samples were collected in five large urban centres across Canada over the period March 2018 to February 2019. In addition to presenting the results by month and by city for certain drugs, this document presents preliminary estimates of total use of cannabis, methamphetamine, and cocaine.

  • 3. Analysis of trends in the prevalence of cannabis use and related metrics in Canada
    Articles and reports: 82-003-X201900600001
    Description:

    The Canadian federal government legalized non-medical cannabis use by adults in October 2018. Ongoing monitoring of the effects of the change is needed because uncertainty remains about the impact of this legislation on cannabis use behaviours and whether the impact will affect some more than others. This study used data from Canadian Alcohol and Drugs Survey and its predecessor to examine longer-term historical rates of use during 2004 to 2017. Five iterations of National Cannabis Surveys (2018/2019) were used to examine current use (overall, daily/almost daily, quantities, and types of products) in the months before and after legalization.

Search help

How do I use the filters and the search box?

  • You can initiate a search by entering keywords or selecting filters (e.g., under Subject, Geography, etc.) on the left side of the page.

  • Filters can be used together or in any combination. Each time you select a filter, the results on the page are updated.

  • To start a new search, click on the Clear all button above the search box or deselect each filter.

  • Specified keywords and filters appear above the search box. You can deselect any or all the tags to refine or clear your search.

How do I refine my search?

  • You can enter keywords in the search box. It is not necessary to use “+” or “, “ or “AND”.

  • You can delete some or all of the keywords from your search string.

  • Quotes around keywords limit the search to a specific phrase.

    • For example, “labour force survey” will limit results to products containing this phrase.

  • Use “or” between keywords to obtain results that contain one or more search terms.

    • For example, labour or­ force or survey will limit results to products containing any or all of these words.

How does the search work?

  • This search looks for results that have your query term in the title, description, subject, geography, product number or other information about the product.

    • For example, when searching the term ‘Diseases’, all results with the word ‘Diseases’ in the title, description or tagged the subject appear.

  • The text within an article or publication are not searched. For full text searching of articles, use the site search.

Sort help

How are the results ordered?

The Sort by feature provides three options:

  • By date – sorts results by product release date starting with the most recent.
  • By relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.
  • By title – sorts results alphabetically.

  • By date – sorts results by product release date starting with the most recent.
  • By most popular – gives priority to results that are most frequently selected by users, followed by the most recent.
  • By relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.
