The data presented in this report are weighted estimates, generated using SAS 9.4 unless otherwise noted. Estimates are not reported where specific categories include less than 30 individuals (unweighted), except where noted as not meeting Statistics Canada’s quality standards. The CTADS/CTUMS survey weights assigned by Statistics Canada in the annual datasets were used for CTADS/CTUMS analyses, and the CSTADS/YSS survey weights were used for CSTADS/YSS analyses. CTADS/CTUMS and CSTADS/YSS were not analysed together and there was no overlap of the survey weights between the two surveys.
Statistical comparisons between groups/years were tested using weighted regression analyses in SAS 9.4 or Stata 14.2. Bootstrap weights were used to perform significance testing where available. Where statistical testing has been performed, comparisons are marked with a superscript number, which refers to a p-value that can be found in the Index of Statistical Tests. Throughout the report, the term “significant” has been reserved for instances where statistical testing has been performed, with p<0.05 as the cut-off for significance.
Data analysis was completed by Ulaina Tariq, MSc, Robin Burkhalter, MMath, and Vicki Rynard, MSc, of the Propel Centre for Population Health Impact, using datasets made available by Statistics Canada and Health Canada. Statistical guidance for previous editions was provided by K. Stephen Brown, PhD, of the Department of Statistics & Actuarial Science, University of Waterloo. We are also grateful to Rashid Ahmed, PhD, for statistical contributions to previous editions.

The 2019 Edition
This report updates the previous (2017) edition with current data, including the 2017 wave of the Canadian Tobacco, Alcohol and Drugs Survey (CTADS) and the 2016-17 Canadian Student Tobacco, Alcohol and Drugs Survey (CSTADS).
NOTE: Prior cycles of the CSTADS/YSS collected data from grade 6 students. The results in this report reflect a reanalysis of the CSTADS/YSS data to include only students in grades 7 to 9, for accurate comparison to CSTADS 2016-17 data.
