Cannabis is a green or brown tobacco-like substance consisting of the dried flowering tops and leaves of the cannabis plant, Cannabis sativa. Hashish or cannabis resin is the dried brown or black resinous secretion of the flowering tops of the cannabis plant. Cannabis is a controlled substance under the Controlled Drugs and Substances Act, meaning that the acts of growing, possessing, distributing and/or selling cannabis are illegal.
Cannabis is the most commonly used illegal drug in Canada and worldwide. According to the 2010 Canadian Alcohol and Drug Use Monitoring Survey, 10.7% of Canadians aged 15 years and older reported past-year use of cannabis. The use of cannabis is generally more prevalent among youth, with approximately 25.1% of 15- to 24-year-olds reporting use of the drug during the past year compared to the 7.9% among adults 25 years and older. Approximately 45% of past-year cannabis users in Canada aged 15 and older reported using cannabis less than once a month during the three months prior to being surveyed. A sizeable percentage of past-year users indicated that they use cannabis more regularly on either a weekly (19.2%) or daily/almost daily (20.3%) basis.
