In 2023, the number of patients treated on the adult mental health ward in Guernsey was lower than in the previous year. A report by the States found that one in four admissions to the ward were likely linked to cannabis use, compared to only 4% in 2019 when medicinal cannabis prescriptions were introduced. While there may be other contributing factors, doctors believe that cannabis is a significant factor in these admissions.
The report revealed that 25% of the total admissions to the in-patient mental health facility were related to cannabis use. Although it is not definitively proven that cannabis is solely responsible for these admissions, the increase in cases suggests a strong connection. This trend is consistent with international experiences and is impacting individuals, carers, and the mental health service in Guernsey.
Despite the increase in admissions related to cannabis, the report notes that 94% of heavy cannabis users do not experience psychosis. Additionally, referrals to the Child and Adolescent Mental Health Service have increased by 14% from 2022 to 2023, indicating a growing need for early intervention in mental health issues.
Overall, the total number of nights spent by patients on the mental health ward in 2023 was slightly lower than the previous year. Dr. Nicola Brink, director of public health, commended the progress made in implementing the Mental Health and Wellbeing Strategy since its launch in September 2023. Jo Cottell, chief executive of Guernsey Mind, also highlighted the collaborative efforts across various sectors to raise awareness of mental health and the importance of prevention and early intervention.
