The review evaluated results from both randomized controlled trials (RCTs) and uncontrolled investigations, defining positive outcomes as meaningful enhancements in sleep architecture or self-reported sleep quality. However (additional studies), especially controlled clinical trials, are necessary to better understand these relationships, establish causality, and guide safe and effective use of cannabis products for sleep disorders.
