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.

What are some symptoms of cannabis withdrawal syndrome (CWS)?

CWS involves 3 or more of the following symptoms within 7 days of reduced cannabis use (1):

  • Anxiety
  • Depression
  • Changes in sleep
  • Irritability, anger, or aggression
  • Appetite or weight disturbance
  • Restlessness
  • Somatic symptoms, such as headaches, sweating, nausea, vomiting, or abdominal pain.

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.
