Introduction
Sleep quality is a significant concern for many people around the world, with millions struggling to fall asleep, stay asleep, and wake up feeling refreshed. Traditional treatments like pharmacological interventions and cognitive behavioral therapy have had limited success, often accompanied by side effects or accessibility issues. As a result, there's a growing interest in alternative treatments, including cannabinoids like Cannabinol (CBN) and Cannabidiol (CBD).
A recent study titled "A Double-Blind, Randomized, Placebo-Controlled Study of the Safety and Effects of CBN With and Without CBD on Sleep Quality" by Marcel O. Bonn-Miller and colleagues, published in Experimental and Clinical Psychopharmacology, explores this very topic.
The Study Overview
This study is the first of its kind to evaluate the effects of CBN alone and in combination with CBD on sleep quality through a double-blind, randomized, placebo-controlled trial. Conducted remotely from May to November 2022, the study involved 293 participants aged 18–55, all of whom reported having very poor or poor sleep quality.
Participants were divided into five groups, receiving either a placebo, 20 mg of CBN, 20 mg of CBN combined with 10 mg, 20 mg, or 100 mg of CBD, over seven consecutive nights. The study's primary goal was to measure changes in sleep quality, while secondary measures included sleep onset latency, number of awakenings, wake after sleep onset (WASO), overall sleep disturbance, and daytime fatigue.
Key Findings
- Sleep Quality: The study found that 20 mg of CBN showed a potentially meaningful effect on sleep quality, although it was not statistically significant compared to the placebo.
- Nighttime Awakenings and Sleep Disturbance: More notably, the 20 mg CBN group experienced significantly fewer nighttime awakenings and overall sleep disturbances.
- Daytime Fatigue: Importantly, CBN did not affect daytime fatigue, meaning it improved aspects of sleep without leaving participants feeling groggy during the day.
- Impact of CBD: Adding CBD to CBN did not enhance the effects. None of the CBN + CBD combinations showed significant improvements over CBN alone or the placebo.
Safety and Tolerability
The study also assessed the safety of CBN and CBN + CBD combinations. There were no serious adverse events, and the most common non-serious side effects included somnolence (drowsiness), headache, and sleep disorders. These effects were comparable to those experienced by the placebo group.
Implications and Future Research
This groundbreaking study suggests that a nightly dose of 20 mg CBN could help reduce nighttime awakenings and overall sleep disturbances without impacting daytime alertness. While the addition of CBD did not show additional benefits, the findings open doors for further research into CBN as a standalone treatment for sleep issues.
Given the limitations of traditional sleep aids and the rising interest in natural and alternative treatments, this study provides a promising avenue for those seeking better sleep quality. Future research could explore different dosages, long-term effects, and comparisons with other sleep aids to better understand the full potential of CBN.
