Area of Science:

  • Psychology
  • Substance Use Research
  • Behavioral Science

Background:

  • Understanding the relationship between substance use and emotional regulation is crucial for public health.
  • Marijuana is a widely used substance, and its effects on psychological constructs like anger require investigation.
  • Previous research has yielded mixed results regarding marijuana's impact on aggression and anger.

Purpose of the Study:

  • To examine the association between different levels of marijuana usage and anger expression.
  • To investigate specific patterns of anger (Anger-In, Anger-Out, Total Anger Expression) in relation to marijuana consumption.

Main Methods:

  • Administered the Anger Expression Scale and a marijuana usage questionnaire to 497 undergraduate students.
  • Categorized participants into four marijuana use groups: nonuser, occasional, frequent, and daily user.
  • Utilized statistical analysis, including trend analysis, to assess relationships between variables.

Main Results:

  • No significant differences were found for Anger-In or Total Anger Expression scores across marijuana use levels.
  • Significant differences were observed on the Anger-Out scale among the four marijuana use groups.
  • A significant linear trend indicated that increased marijuana use was associated with higher Anger-Out scores.

Conclusions:

  • Marijuana use, particularly at higher frequencies, may be linked to increased outward expression of anger.
  • The findings suggest a nuanced relationship between marijuana consumption and anger management.
  • Further research is warranted to explore the mechanisms underlying this association and its real-world implications.
