Research has shown that cannabis use increases the risk of paranoia

  • Cannabis for self-medication increases the risk of paranoia.
  • Research revealed a link between childhood trauma and cannabis use.
  • Average THC consumption is higher in individuals with trauma and depression.

Research conducted in London found that people who use cannabis for treating pain, trauma, or depression have a higher risk of developing paranoia than those who do not use it for relaxation. The study involved 3,389 participants over the age of 18 who had previously used cannabis and had a significant history of mental health issues.

Results showed that those who began using cannabis for self-medication had higher paranoia scores. The average THC consumption (active ingredient in cannabis) was 206 units per week. However, those who used cannabis for treating trauma or depression consumed an average of 248 and 254.7 units, respectively.

Only some patients, such as children with rare forms of epilepsy and adults with treatment-resistant conditions, are prescribed medical cannabis in England by the NHS. Private clinics tend to prescribe cannabis for a wider range of conditions, including chronic pain and various mental health issues.

Research also revealed a link between childhood trauma and increased paranoia among cannabis users. Over 50% of respondents reported childhood trauma, with those experiencing physical or emotional abuse having paranoia scores 35-40% higher.

Experts emphasize the need for increased awareness of the potential risks associated with cannabis use, as regular consumption of high-potency cannabis may increase the risk of developing psychosis five times compared to those who have never used cannabis. The study highlights the necessity of early identification of trauma in individuals who turn to cannabis.
