Pharmacological and physiological effects of cannabidiol: a dose escalation, placebo washout study protocol

At the Brain Health and Wellness Lab at the University of Regina, our latest research focuses on the impact of cannabinoids on sleep quality. In this study, we explore how CBD and ∆9-THC influence sleep, analyzing both objective data from actigraphy and subjective experiences reported by participants.

Actigraphy—a scientifically validated tool similar to a FitBit but more precise—allows us to measure time spent in bed, sleep duration, and wakefulness after sleep onset. Additionally, participants complete the Leeds Sleep Evaluation Questionnaire to provide insights into their perceived sleep quality.

While research on cannabinoids and sleep is still in its early stages, existing evidence suggests potential improvements in sleep quality. Our work contributes to this growing field by offering a deeper understanding of how these compounds may support better rest.
