Summary
This study tested a capsule containing cannabidiol (CBD) and terpenes to see if it improves sleep quality in people with chronic insomnia. 125 adults with insomnia took either the CBD capsule or a placebo for a period, and their sleep was tracked with a wrist device. The goal was to measure time spent in deep and REM sleep stages.
