Abstract

OBJECTIVE: To document the prevalence and correlates of suicidal ideation (SI) among individuals seeking cannabis-based medicinal products (CBMPs); to test whether SI declines or intensifies after three months of CBMP treatment and to document 12-month trajectories of depression in those reporting SI and other patients.

METHOD: Observational data were available for 3781 patients at entry to treatment, 2112 at three months and 777 for 12 months. Self-reported depressed mood and SI were assessed using items from the PHQ-9. Additional data included sociodemographic characteristics and self-reported well-being.

RESULTS: 25% of the sample reported SI at treatment entry and those with SI had higher levels of depressed mood (mean = 17.4 vs. 11.3; F((1,3533)) = 716.5, p <.001) and disturbed sleep (mean = 13.8 vs. 12.2, F((1,3533)) = 125.9, p <.001), poorer general health (mean = 43.6 vs. 52.2, F((1,3533)) = 118.3, p <.001) and lower quality of life (mean = 0.44 vs. 0.56 (F((1,3533)) = 118.3, p <.001). The prevalence of SI reduced from 23.6% to 17.6% (z = 6.5, p <.001) at 3 months. Twelve-month follow-up indicated a substantial reduction in depressed mood with this reduction being more pronounced in those reporting SI (mean ((baseline)) = 17.7 vs. mean (12 months) = 10.3) than in other patients (mean ((baseline)) = 11.1 vs. mean ((12 months)) = 7.0).

CONCLUSIONS: SI is common among individuals seeking CBMPs to treat a range of chronic conditions and is associated with higher levels of depressed mood and poorer quality of life. Treatment with CBMPs reduced the prevalence and intensity of suicidal ideation.
