"In 2012, past-year use of the most commonly reported illicit drugs after cannabis was estimated to be about 1% for each (ecstasy (0.6%), hallucinogens including salvia (1.1%) and cocaine or crack (1.1%)). Past-year use of speed, methamphetamine or heroin is not reportable. There were no changes in prevalence of any of these drugs individually, between 2012 and 2011 or between 2012 and 2004.
"Use of at least one of five illicit drugs excluding cannabis [cocaine or crack, speed, ecstasy, hallucinogens (including salvia) or heroin] was reported by 2.0% of Canadians and is not different from 2011 (1.9%). The reported rate of such use by males (3.1%) was almost triple that reported by females (1.1%), while the rate of use by youth (6.5%) was five times higher than that reported by adults (1.2%). Rates are not comparable to 2004 because salvia was not included in the CAS [Canadian Addiction Survey].
"Users of illicit drugs were asked how easy it would be for them to get that specific drug if they wanted some “now”. Most users of cannabis (84.5%) and cocaine (77.8%) said it would be easy or very easy to get. Results for other drugs are not reportable due to low numbers and small sample size."

"Some key findings from the report are as follows. Among students in grades 7, 9, 10, and 12 (i.e., those approximately 12–18 years old):
"• Alcohol use is almost twice as prevalent as cannabis use (46–62% of students report alcohol use and 17–32% report cannabis use in the past year, depending on the province);
"• 19–30% report consuming five or more drinks on a single occasion in the past month;
"• 12–20% of Grade 12 students report driving within an hour of drinking alcohol in the past year;
"• 26–38% of all students report that in the past year they have been a passenger with someone that had been
drinking, and 17–20% report that in the past year they have been a passenger with someone who had had ‘too much’ to drink;
"• 2–5% report using cannabis daily or almost daily;
"• 14–21% of students in Grade 12 report driving within an hour of using cannabis, and more than 33% of Grade students report having been a passenger with someone who had used cannabis; and
"• Among the drugs assessed by the surveys, aside from alcohol and cannabis, ecstasy is the most prevalent drug (4–7% report lifetime use) followed by inhalants (2–4% report lifetime use)."

"The reported prevalence of drugs (other than alcohol and cannabis) such as cocaine or heroin among students is relatively rare. That said, provinces routinely measure use of these substances. British Columbia, Alberta, Manitoba, and Ontario estimates are for lifetime use. Atlantic provinces, Québec and the YSS [Youth Smoking Survey] ask about use in the past 12 months. Therefore, the two sets of prevalence estimates are presented separately in different tables. In addition to the different time frames used in the survey questions, there is also considerable variation in the terminology used in referring to these drugs as noted where appropriate in the tables below.
"All the surveys ask about ecstasy. Estimates for ecstasy use range from 3.4–7.2% reporting past-12-month use
and 4.4–7.1% reporting lifetime use (Tables 43 and 44). Following ecstasy, inhalants are second overall in reported
use with estimates ranging from 2.6–4.4% for past-year use and 2.2–3.8% for lifetime use. However, not all surveys ask about use of inhalants; some ask about ‘solvents’ or ‘glue’. These differences in terminology result in different prevalence estimates (Tables 45 and 46). Estimates for steroid use range from 1.4–1.7% for past-12-month use and 1.2–1.4% for lifetime use (Tables 47 and 48). Estimates for lifetime heroin use in British Columbia, Alberta, Manitoba and Ontario range from 0.8–1.3% (Table 49). Atlantic Canada does not ask students about heroin use. The YSS asks about past-12-month use of heroin [1.3% (1.0, 1.6)]."
