"Eight of the nine provinces with student drug use surveys ask about daily or almost daily use of cannabis in the past month. Overall, 2.2–5.3% of students report smoking cannabis every day or almost every day in the past 30 days (Table 31 and Figure 31). In four of the eight provinces, the prevalence of daily or almost daily cannabis use was significantly greater among males than females (Table 32 and Figure 32). When examined by grade, the same pattern as noted in all previous indicators emerges. In Grade 7, very few students report daily use - so few that most estimates for Grade 7 students are suppressed. In Grade 12, however, 3.3–10.0% of students report using cannabis daily or almost every day (Table 33 and Figure 33)."
