Key finding

Sleep A (low THC + high botanicals) showed significant improvements in sleep disturbance, anxiety, stress and wellbeing compared to placebo; Sleep B showed no significant differences.

Summary

n=620 adults with sleep disturbances, 3-arm RCT over 4 weeks. Sleep A (0.35 mg THC + 75 mg hop/valerian) vs. Sleep B (0.85 mg THC + 20 mg hop/valerian) vs. placebo. Sleep A showed significant improvement in PROMIS Sleep Disturbance versus placebo (p<0.05, exact value not given); additionally reduction in anxiety, stress and improvement in wellbeing. Sleep B showed no significant differences versus placebo. Adverse events mild to moderate, no group differences.

Abstract
Inadequate sleep is a global health concern. Sleep is multidimensional and complex; new multi-ingredient agents are needed. This study assessed the comparative effects of two multi-ingredient supplements on sleep relative to placebo. Adults (N = 620) seeking better sleep were randomly assigned to receive one of three study products. Sleep A (contained lower (0.35 mg THC and higher levels of botanicals (75 mg each hops oil and valerian oil), Sleep B (contained higher THC (0.85 mg) and lower botanicals (20 mg each hops oil and valerian oil) or placebo) for 4 weeks. Sleep disturbance was assessed at baseline and weekly using NIH's Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance SF 8A survey. Anxiety, stress, pain, and well-being were assessed using validated measures at baseline and weekly. A linear mixed-effects regression model was used to assess the change in health outcome score between active product groups and the placebo. There was a significant difference in sleep disturbance, anxiety, stress, and well-being between Sleep A and placebo. There was no significant difference in any health parameter between Sleep B and placebo. Side effects were mild or moderate. There were no significant differences in the frequency of side effects between the study groups. A botanical blend containing a low concentration of THC improved sleep disturbance, anxiety, stress, and well-being in healthy individuals that reported better sleep as a primary health concern.
