A previous post discussed cannabis (marijuana) use and Memory and academic performance and symptoms of depression and anxiety from cannabis withdrawal.

This post talks about a study looking at cannabis use and suicidal ideation.

What was the study (1)?

Dr Han and colleagues looked at data from 281 650 adult participants in the 2008-2019 National Surveys of Drug Use and Health data.

What were some study results (1)?

  • Past-year Cannabis use disorder, daily cannabis use, and nondaily cannabis use were associated with a higher prevalence of past-year suicidal ideation, plan, and attempt in both sexes (eg, among individuals withoutMajor depressive episode.)
  • The prevalence of suicidal ideation for those with vs without Cannabis use disorder was 13.9% vs 3.5% among women and 9.9% vs 3.0% among men; P < .001).
  • Suicide plan among those with Cannabis use disorder and major depressive episode was 52% higher for women [23.7%] than men [15.6%]; P < .001).

What are some caveats?

  • This is just one study and further research is needed.
  • While this study shows correlation between cannabis and suicidal ideation among those with depression, but does not show direct cause and effect.
  • Future research is needed to examine this increase in suicidality and to determine whether it is due to cannabis use or other overlapping risk factors.
  • According to this study, cannabis use can be concerning for suicidal ideation for those with and without major depressive disorder.
