The starting point for the CEA is the volume of cannabis consumed in Canada taken from recent work published by Statistics Canada (Ryan Macdonald and Michelle Rotermann), which estimates the consumption of cannabis in Canada by age group from 1960 to 2015. These estimates were smoothed using a Hodrick-Prescott filter and trended forward to 2017 using population growth estimates by age group for the years 2016 and 2017. This most likely underestimates the 2016 and 2017 volume as it does not consider potential changes in behaviour that could be occurring in anticipation of legalization. The 2016 and 2017 estimates of the volume of cannabis consumed should be considered as lower bound estimates. These estimates will be revised when the results from the 2017 Canadian Tobacco, Drugs and Alcohol Survey (CTADS 2017) are released later this year (2018).
The estimated volume of cannabis consumption (Vc) in 2017 was 773 metric tonnes.
