Cannabis use and suicidal behaviours in high-school students

Area of Science:

• Adolescent mental health
• Substance use research
• Behavioral psychology

Background:

• Adolescent mental health is a growing concern, with suicidal behaviors posing a significant risk.
• Co-occurring mental health conditions like depression and anxiety are common in adolescents.
• The role of substance use, particularly cannabis, in adolescent mental health requires further investigation.

Purpose of the Study:

• To determine the independent predictive value of cannabis use on suicidal behaviors.
• To assess the relative contributions of cannabis use, depressive symptoms, and anxious symptoms in predicting suicidal behaviors among high school students.

Main Methods:

• Cross-sectional study design involving 248 high-school students.
• Utilized self-report questionnaires to assess cannabis use, depressive symptoms, anxious symptoms, and suicidal behaviors.
• Statistical analysis employed to evaluate the predictive relationships between variables.

Main Results:

• Cannabis use emerged as a significant independent predictor of suicidal behaviors.
• This association remained significant even after controlling for the effects of depressive and anxious symptoms.
• Depressive and anxious symptoms also showed associations with suicidal behaviors, but cannabis use provided unique predictive power.

Conclusions:

• Cannabis use is a critical factor to consider when assessing suicide risk in adolescents.
• Clinical interventions and prevention strategies for adolescent suicidal behaviors should incorporate screening for and addressing cannabis use.
• Further research is warranted to explore the mechanisms underlying the link between cannabis use and suicidal behaviors in this population.
