A recent report by the States of Guernsey has highlighted a concerning trend in admissions to the island’s adult mental health ward. According to the report, one in four admissions in 2023 to the Crevichon Ward at Princess Elizabeth Hospital were likely linked to cannabis use. This marks a significant increase from just 4% in 2019, which coincided with the introduction of medicinal cannabis prescriptions.
The figures, presented in the annual mental health strategy report, are based on clinical assessments. While other factors may also contribute to these admissions, medical professionals believe cannabis use is a prominent factor in many cases.
Specifically, out of the total admissions in 2023, 27 cases—equivalent to 25%—were associated with cannabis use. The report stresses that cannabis may not be the sole cause of these admissions, but the notable rise suggests it plays a substantial role.
International experiences support these findings, indicating a similar impact on mental health services and individuals in other regions. Despite this, the report highlights that the majority of heavy cannabis users—94%—do not experience psychosis.
In addition to adult admissions, the report also notes a 14% increase in referrals to the Child and Adolescent Mental Health Service, rising from 585 in 2022 to 684 in 2023. Despite these challenges, there was a slight decrease in the total number of nights patients spent at Crevichon Ward compared to the previous year.
Dr. Nicola Brink, director of public health, commended the progress of the Mental Health and Wellbeing Strategy since its launch in September 2023. She emphasized the importance of a comprehensive approach to mental health across all sectors to address various social, economic, and environmental factors impacting mental wellbeing.
Jo Cottell, chief executive of Guernsey Mind, expressed satisfaction with the collaborative efforts highlighted in the report. She underscored the ongoing initiatives by charitable organizations, the States of Guernsey, and other partners to raise awareness about mental health and prioritize prevention and early intervention.
Overall, the report serves as a critical assessment of the current state of mental health services in Guernsey, emphasizing both challenges and strides in addressing mental health issues across different age groups and the community at large.
