Recommendations on behavioural interventions for the prevention and treatment of cigarette smoking among school-aged children and youth
Among Canadian youth, 18% have tried cigarettes, with the range increasing from 3% among children in grade 6 to 36% among youth in grade 12. A person who starts smoking as a child or youth is less likely to quit later in life than someone who starts later. Factors such as age, sex, the influence of friends and family, and the broader social environment of school and community are linked to a youth’s decision to start smoking. Almost 90% of adult smokers first smoked tobacco by age 18.
