Cannabis (marijuana) and suicidal ideation

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 without Major 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.

During times of stress people may become vulnerable to using cannabis as a way to cope.

Previous posts have discussed the negative impact of cannabis on memory, cognitive performance, and PTSD.

Cannabis withdrawal can cause and worsen a variety of mental health symptoms.

It is important become aware of this connection for mental health.

  • Anxiety
  • Depression
  • Changes in sleep
  • Irritability, anger, or aggression
  • Appetite or weight disturbance

How common is cannabis withdrawal syndrome?

A meta-analysis(2) of 47 studies including 23,518 participants, found that the prevalence of cannabis withdrawal syndrome was found to be 47% (2).

What are some factors that were associated with higher cannabis withdrawal syndrome (2)?

Researchers (2) found that Daily cannabis use, concurrent tobacco use, and use of other substances was associated with higher CWS (2).

Other thoughts:

  • It bears repeating that daily users were more likely to have cannabis withdrawal syndrome.
  • Some people may report cannabis use helping with anxiety, depression, or insomnia when it may just be masking the withdrawal symptoms caused by previous cannabis use.
  • Research shows an association between cannabis use and several medical, cognitive, functional, and psychosocial problems(3).
  • Short-term risks of cannabis use include impaired short-term memory motor dis-coordination, altered judgment, paranoia, and psychosis (4).
  • Some long-term effects of cannabis use include addiction, altered brain development, poor educational outcomes, cognitive impairment, diminished quality of life, increased risk psychotic disorders, injuries, motor vehicle collisions, and suicide (4,5).
  • Further research is needed on cannabis and mental health.
