Problematic Substance Use Prevention

Brief overview

Many young people experiment with substance use at some point during their development. For some students, this experimentation is low risk and for a relatively short period of time. For others, it may develop into a significant problem.

Substance use occurs along a spectrum (commonly called a continuum of use) ranging from no use at all to experiencing a substance use disorder. A comprehensive approach requires evidence-based strategies that address the needs of all students, regardless of where they fall on the continuum of use.

The role of the SMH professional

As a SMH professional, you have a role to play in supporting educators with mental health promotion efforts, and in providing prevention and early intervention services in this area.

Research suggests that school communities can play an important role in preventing problematic substance use by

  • fostering welcoming and inclusive environments
  • offering universal mental health promotion programming and encouraging self-care
  • enhancing social-emotional skills to build confidence and resilience

SMH Professionals can help to convey the importance of building social-emotional skills and creating a sense of belonging at school to reduce the risk of problematic substance use.

Any adult in a caring relationship with students can play a role in early intervention by noticing that substance use may be impacting students’ lives.  You may wish to share the educator version of this info-sheet with school staff to help them notice signs of problematic substance use.  They are the eyes, ears and hearts who may notice first.  As a SMH professional, it could be you that notices signs that may point to the presence of a substance use problem.  Common signs you might notice when working with a student include

  • ignoring responsibilities at work, school, or home
  • giving up activities that they used to find meaningful or enjoyable
  • changes in mood (e.g., feeling irritable and paranoid)
  • changing friends
  • having difficulties with family members, friends, and peers
  • being secretive or dishonest
  • changing sleep habits, appetite, or other behaviours
  • borrowing money or having more money than usual

Some students require additional opportunities to build resilience and coping skills.  Strategies for prevention include

  • small group interventions that promote protective factors and wellbeing with youth who experience additional risk factors
  • individual or group structured psychotherapy designed to address mild-to-moderate anxiety and depression

Educators can also reinforce skills as part of daily classroom life. You can offer the educator version of this information for suggestions.

Trained SMH professionals may undertake intervention using Motivational Enhancement Therapy (including Motivational Interviewing) and Cognitive Behavioural Therapy approaches for students with identified problematic substance use concerns.  Some students with more significant needs in this area will require referral to more specialized substance use services.
