A recent report from the States has unveiled a concerning trend in mental health cases related to cannabis use. Rising Numbers: The data shows that one in four admissions to Guernsey's adult mental health ward in 2023 were likely linked to cannabis, a significant increase from just 4% in 2019. This finding is based on clinical judgment, indicating a strong correlation between cannabis use and mental health issues. Impact on Admissions: The report highlights that 27 out of 100 admissions to the Crevichon Ward were associated with cannabis use. While it's not conclusive that cannabis was the sole cause of these admissions, the evident rise in such cases suggests a compelling connection. International Consistency: The report mentions that this trend aligns with experiences seen globally and is impacting individuals, carers, and the mental health service. Despite 94% of heavy cannabis users never experiencing psychosis, the overall increase in referrals to mental health services is a cause for concern. Focus on Early Intervention: Dr. Nicola Brink, director of public health, commended the progress made in implementing the Mental Health and Wellbeing Strategy since its launch, emphasizing the importance of a comprehensive approach to mental health. Jo Cottell, chief executive of Guernsey Mind, acknowledged the collaborative efforts in raising awareness about mental health and the significance of prevention and early intervention. Moving Forward: While the total number of nights spent by patients on the Crevichon ward slightly decreased in 2023, the need for addressing the impact of cannabis on mental health remains a priority. This study underscores the urgency of addressing this issue and implementing measures for better mental health outcomes.
