See data table below with 95% confidence intervals.As shown in Figure 8.11, cigarette consumption among daily smokers appeared to be lower among students in grades 7-9 (in 2016-17) and age 15-17 than among youth aged 18 and 19 (in 2017).

Among daily smokers aged 15-19, between 1999 and 2017, there appeared to be a net decrease in average daily cigarette consumption, but there has been considerable variation rather than a smooth downward trend, including some periods of increase (Figure 8.12).

Among smokers in grades 7-9, between 1994 and 2014-15, daily consumption varied by survey year, but remained between approximately 8 and 11 cigarettes (Figure 8.12).
