University of North Florida study shows hemp-derived cannabinoid supplement improves sleep quality in trial; participants report enhanced sleep duration, mental health after 10-day treatment

Jacksonville, FL: The oral administration of a hemp-derived supplement containing precise percentages of THC, CBN, and CBD is associated with improved sleep quality, according to placebo-controlled trial data published in Health Science Reports.

Researchers affiliated with the University of North Florida and Jacksonville University assessed the impact of an orally administered cannabinoid supplement versus a placebo in 20 subjects with subthreshold insomnia symptoms.

Compared to the placebo, cannabinoid administration was associated with “significant improvements [from] baseline for sleep latency, sleep duration, and global sleep quality.” Participants also experienced “significant improvements in ‘mental health,’ [and] ‘feeling healthy and full of energy'” after using the cannabinoid supplement for ten days.

“The purpose [of this trial] was to examine the effectiveness of a hemp‐based supplement with CBD, CBN, THC, and a standardized terpene blend on sleep quality/quantity, anxiety, perceived stress, mood, pain, and HRQoL (health-related quality of life) in adults with subthreshold insomnia symptoms using a randomized double‐blind placebo‐controlled crossover pilot trial. We found the CS (cannabinoid supplement) was well‐tolerated and resulted in significant improvements in several sleep quality and health outcomes compared to both baseline and placebo,” the study’s authors concluded. “Improvements in daytime fatigue, pain affected sleep, mood, and anxiety were also associated with CS, though these were nonsignificant condition differences. In conclusion, [hemp-derived cannabinoid] supplementation may be a simple, effective, and well‐tolerated alternative to improve sleep quality and related health outcomes in adults with subthreshold insomnia symptoms.”

The trial’s results are consistent with those of several observational studies finding that patients with insomnia and other sleep disorders experience improvements following their use of cannabis. Studies have also identified a correlation between the adoption of statewide marijuana legalization laws and declining sales of over-the-counter (OTC) sleep aid medications.
