What This Study Found

Cannabis use was significantly associated with increased suicidal ideation among youth. Other associated factors included bullying, other illicit drug use, and identifying as female or other gender. School policies and programs for substance misuse prevention did not mediate the association between cannabis use and suicidal ideation.

Key Numbers

818 youth recruited, 412 provided relevant data. 27 educators surveyed about school policies. Cannabis use, bullying, other drug use, and female/other gender associated with suicidal ideation. School policies had no mediating effect.

How They Did This

Digital citizen science approach engaging 818 youth (13-18 years) and 27 educators via smartphones. Youth responded to time-triggered validated surveys and ecological momentary assessments. Educators reported on school policies. 412 youth provided data on substance use and suicidal ideation. Multivariable logistic regression and mediation analysis.

Why This Research Matters

If school-based substance prevention programs do not reduce the cannabis-suicidality link, different intervention approaches may be needed. The digital citizen science method also demonstrates a novel way to study sensitive topics in real time.

The Bigger Picture

The failure of existing school policies to mediate the cannabis-suicidality association suggests that current prevention approaches may be insufficient or misdirected for addressing this specific risk.

What This Study Doesn't Tell Us

Small analytic sample (412 of 818 recruited). Cross-sectional design. Self-reported data on sensitive topics. School policy measures may not capture implementation quality. Single geographic area.

Questions This Raises

  • ?What types of school interventions would effectively address the cannabis-suicidality link?
  • ?Is the digital citizen science approach more effective at capturing sensitive behaviors than traditional surveys?
