The Royal College of Psychiatrists has issued a stark warning about cannabis and mental health risks following two groundbreaking studies published in BMJ Mental Health and Psychological Medicine that examine links between cannabis use, paranoia, and psychological trauma.

Dr Emily Finch, chair of the Royal College of Psychiatrists’ Addiction Faculty, delivered a compelling response to the research findings, emphasising the urgent need for society to recognise the substantial evidence on marijuana psychological effects.

Addiction Misconceptions Must End

“Society must be more aware of the substantial evidence on cannabis harms, and correct the widespread misapprehension that cannabis is not an addictive substance,” Dr Finch stated emphatically.

The studies reveal troubling connections between first-time cannabis use and subsequent mental health deterioration, challenging popular beliefs about the drug’s safety profile. Research shows that cannabis and mental health impacts extend far beyond casual use assumptions.

Cannabis remains the most widely used illicit substance in the UK, with approximately one-third of users developing problematic relationships with the drug during their lifetime – a proportion comparable to alcohol addiction rates.

Devastating Long-Term Consequences

The marijuana psychological effects prove particularly severe for regular users. Daily cannabis consumption directly correlates with depression, anxiety, and significantly reduced motivation levels, according to the psychiatric experts.

“Daily users of high-potency cannabis are nearly five-times more likely to develop a psychotic disorder than people who have never used cannabis, with adolescents at particular risk,” Dr Finch warned.

The studies published on 27 August 2025 examine critical aspects of cannabis and mental health impacts, including reasons for initial use and associations with subsequent THC intake and symptoms of paranoia, anxiety, and depression.

Young People Face Greatest Threat

Adolescents bear disproportionate risks from marijuana psychological effects, with developing brains proving especially vulnerable to cannabis-induced psychological damage. The research highlights how childhood trauma intersects with cannabis use to increase paranoia risks substantially.

Both natural and synthetic cannabinoids present long-term addiction risks alongside severe co-occurring mental illness complications, creating complex treatment challenges for healthcare providers.

Urgent Government Action Required

Dr Finch called for immediate governmental intervention to address the cannabis and mental health crisis. “As a priority, the UK Government must provide substance use and mental health services with the training, staff, and funding they need to support people with co-occurring substance use and mental illness.”

The psychiatric expert emphasised the critical importance of early intervention for children and young people struggling with substance misuse to prevent long-term psychological damage.

The studies, led by researchers Edoardo Spinazzola and Giulia Trotta respectively, provide compelling evidence that challenges misconceptions about cannabis safety and highlights the serious marijuana psychological effects that users face.

Healthcare professionals now possess stronger scientific evidence to support treatment approaches for individuals experiencing cannabis and mental health complications, particularly those involving paranoia and trauma-related symptoms.
