Strong parent and peer relationships reduced marijuana use among teen bullies and bully-victims

Cross SectionalModerate evidence
The takeaway

Among 12,642 adolescents, those who were bullies or bully-victims were more likely to use marijuana, but stronger parental attachment and prosocial peer relationships significantly reduced this risk.

School counselors, youth prevention program designers, and parents of adolescents involved in bullying.

Parental attachment reduces risk

What the researchers found

Adolescent bullies and bully-victims had higher marijuana use rates than victims or uninvolved youth. Parental attachment and prosocial peer attachment significantly decreased marijuana use likelihood for bullies and bully-victims, partially mediating the bullying-marijuana relationship. Pure victimization alone was not significantly related to marijuana use.

Why it matters

This identifies modifiable protective factors (family and peer relationships) that could be targeted in prevention programs for the specific youth most at risk: those who bully others or experience both sides of bullying.

The numbers in context

12,642 adolescents. Bullies and bully-victims had significantly higher marijuana use. Parental attachment and prosocial peer attachment both significantly reduced marijuana use. Social controls partially mediated the bullying-marijuana link.

How the study worked

Cross-sectional analysis of 12,642 adolescents from the Health Behavior in School-Aged Children survey. Multiple mediation approaches tested the role of social control measures between bullying status and marijuana use.

What this study cannot tell us

Cross-sectional design. Self-reported bullying and substance use. Cannot determine temporal order. Social desirability bias may affect reporting of both bullying and marijuana use.

How to read the evidence

Rated moderate because the large nationally representative sample provides robust data, though the cross-sectional design limits causal inference.

When this study was published

Published in 2019.

The bigger picture

Bullying and substance use are often treated as separate problems in schools. This study suggests they share common protective factors, meaning interventions that strengthen family and peer connections could address both simultaneously.

Questions still open

  • Would family-strengthening interventions reduce marijuana use in bullying youth? Why does victimization alone not predict marijuana use? Do these relationships hold across different cultural contexts?

Common questions

Does bullying lead to marijuana use?
Bullies and bully-victims (not pure victims) had higher marijuana use. Stronger family and peer relationships reduced this risk, suggesting social connection is protective.
What can parents do?
Parental attachment was a significant protective factor against marijuana use in bullying youth, suggesting that maintaining strong parent-child relationships can buffer against substance use risk.
