Substance Use/Addictions

Substance Use, Addictions, and Related Behaviours

Schools have a unique opportunity to positively influence students through educating, role modeling, and creating healthy and supportive learning environments.

What Works?

Alcohol and substance use prevention efforts in schools are best achieved by:

  • Promoting students’ well-being and fostering welcoming environments.
    • Creating a school environment where students feel like they belong.
    • Encouraging recreational and extracurricular activities where adult role models help students develop a positive sense of self.
    • Establishing supportive and caring relationships with students.
    • Supporting positive peer relationships.
    • See videos:

  • Providing opportunities for students to have open, non-judgemental conversations and to develop and practice media literacy and social emotional learning skills in a safe and inclusive space.
    • Providing knowledge and skills prior to the behaviour and at transition periods.
    • Teaching in the context of developmentally appropriate information (e.g., abstinence vs. harm reduction).
    • Providing booster sessions over a number of years that reinforce the knowledge and skills.
    • Applying knowledge and practicing skills that are relevant to their experience, in a low risk situation, and using “real-world” situations.
  • Presenting honest and factual information in a supportive and non-judgemental way while avoiding scare tactics.
  • Providing opportunities for active learning and engaging students in planning and delivering programs and initiatives.
  • Providing substance use awareness activities that consider the following:
    • Guest presentations and/or “lived experience” presentations can work well when the message is clear, known ahead of time, and when there are supporting activities that go beyond the actual presentation to reinforce the messages with students.
    • Messages should be evidence based and consistent with your school board approach.
    • Particular attention should be focused on vulnerable students that may be triggered by the presentation content. Informing parents of the presentation goals and messages prior will allow there to be an informed decision made regarding the student’s attendance.
    • For more information, refer to the School Mental Health Decision Support Tool.
  • Being a positive role model and avoiding modelling positive views about the pleasures of substance use (even when speaking to other adults in student spaces).
  • Including families in prevention efforts, when possible.
  • Becoming familiar with the general signs and symptoms associated with substance use.
  • Connecting students and families to community supports, when appropriate.


Resources to support implementation can be found in the sections below. Educators may also contact their School’s Public Health Nurse for additional support and consultation.

Be. Do. Lead.

History has taught us that young people are the ones who ignite change. They question the status quo and imagine how things could be done differently. Help turn their passion into action with these 4 youth self-directed E-modules for youth advocacy (15–30 minutes each).

Centre for Addiction and Mental Health (CAMH) (Grade 1–10)

CAMH offers an integrated set of web based resources for teachers, schools and allied partners to utilize in their prevention/health promotion work with youth.

The Fourth R (Grades 7–9)

Contact the Health Unit for a consultation on this program.

The Fourth R is a comprehensive school-based prevention program based on extensive research. It applies best-practice approaches to building skills and reducing harm among adolescents. The contention of the Fourth R is that relationship skills can be taught in the same way as reading, writing and arithmetic. During the course of the lessons, students will engage in extensive skill development and role-play activities to help develop effective and healthy responses to situations of conflict and violence. Adolescents require opportunities to learn new skills (e.g., assertiveness, communication, and problem-solving), and practice applying them in a range or realistic situations within a safe environment.

Currently our agency recommends the sections that address Personal Safety and Injury, and Substance Use, Addictions and Related Behaviors. Please see the section on Healthy Eating and Sexual Health for resources supporting those themes.

The Health Unit can support school implementation by:

  • Providing resources to support student engagement
  • Supporting student groups/clubs (e.g. Gay-Straight Alliances, OSAID, Student Health Clubs)
