Real-world quality of life and sleep outcomes in patients treated with THC- and CBD-rich Cannabis oil: a cross-sectional study.

The endocannabinoid system plays an important role in the modulation of pain, mood, sleep, and subjective wellbeing. Despite the growing clinical use of medicinal Cannabis, real-world data simultaneously evaluating quality of life and sleep-related outcomes in heterogeneous clinical populations remain limited. This study aimed to assess quality of life and sleep satisfaction in patients using medical Cannabis oil under supervised clinical follow-up. This cross-sectional observational study included patients treated with full-spectrum medical Cannabis oil rich in tetrahydrocannabinol (THC) and cannabidiol (CBD) in a real-world clinical setting. Quality of life was assessed using the World Health Organization Quality of Life-BREF (WHOQOL-BREF), and sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). Sociodemographic, clinical, and treatment-related data were collected via an electronic questionnaire. Nonparametric analyses, Spearman correlation, and ordinal logistic regression models were performed. Seventy-one participants were included, predominantly female, with diverse clinical conditions. Participants reported generally favorable perceptions regarding quality of life and sleep satisfaction, with median scores concentrated in the higher response categories. Positive correlations were observed between the psychological domains of quality of life and sleep satisfaction. Higher Cannabis oil concentrations and longer treatment duration were associated with higher odds of better outcomes. In a real-world clinical context, supervised use of full-spectrum medical Cannabis oil was associated with favorable patient-reported perceptions of quality of life and sleep, consistent with perceived effectiveness. These findings highlight the need for longitudinal studies with pre-treatment baseline assessment.
