Cannabis, CBD, and Sleep
In summary, this study demonstrates that CBD may significantly reduce anxiety and, to a lesser extent, improve sleep in a psychiatric outpatient population. Nevertheless, the outcomes of this study provide useful clinical insights into the potential role of CBD in the treatment of anxiety and sleep disorders. These design limitations mean that the findings should be interpreted with caution and considered preliminary. Some individuals maintained improved sleep, while others experienced a recurrence of symptoms, indicating that the effect of CBD on sleep may fluctuate and could be influenced by additional factors such as stress or coexisting conditions. After one month of treatment, approximately 79% of patients reported a significant reduction in anxiety symptoms.
In summary, most of these studies evaluating effects of cannabis and cannabinoids are limited by differences in study designs, sample sizes, and procedures, as well as the ratios of THC to CBD used. Thus, studies on the isolated effects of CBD on sleep architecture are limited and mostly have mixed results. Most of the studies examining these effects were polysomnography-based primarily done in the early 1970s. Directly relevant to this review is their potential general sleep-promoting effects and effects on specific aspects of sleep physiology, which may be advantageous in the treatment of some sleep disorders.
Research9 has found that people may experience an endocannabinoid deficiency that results in many different symptoms, including difficulty with sleep. In the 1900s, scientists discovered the existence of a biochemical communication system in the body known as the endocannabinoid system8. For example, among those with generalized social phobia, medication with CBD significantly reduced anxiety, cognitive impairment, and speech performance discomfort.7 Walking into your local gas station or pet store, you’ll likely notice the wide range of CBD oil products available as pure oils, tinctures, gummies, vapors, and more. In this evaluation, CBD appears to be better tolerated than routine psychiatric medications.
CBD Gummies by R&R serve multiple functions.
She drew attention to a systematic review on CBD and sleep, which found somewhat positive results (with or without THC), but noted many issues with the evidence including very few studies focusing specifically on patients with insomnia. Sleep problems are also very common, with approximately 30% of the population having symptoms of insomnia at least occasionally. Your own tracking will help you find the pattern that works for your body. The most commonly reported side effects are dry mouth, drowsiness, fatigue, reduced appetite, and diarrhea.
CBD might have a positive impact on certain cannabinoid receptors that affect anxiety. Although evidence is still keeping indoor spaces fresh after plant-based smoke limited, research indicates that CBD may have anti-anxiety properties. A few small studies have examined CBD as a potential treatment for sleep disorders.
A potential side effect of melatonin is the possibility of feeling drowsy the following day. The monthly subscription cost is $77, a price that is significantly lower yet still higher than the cost of a two-month supply of Medterra. To fully experience the tincture’s benefits, it is important to keep it under your tongue for a duration of 45 to 60 seconds.
It is not surprising that CBD may assist with a variety of symptoms and health issues.

Other options that may be considered include magnesium, L-tryptophan, 5-HTP, or melatonin. When considering a CBD product, it is advisable to select one whose ingredients have been verified by an independent laboratory. For instance, you might be using a medication (Drug A) that effectively treats a condition but has the unfortunate side effect of slight dizziness. If you opt to add CBD to your existing medication regimen, it may influence the duration that the other medication remains in your body.
In contrast, its benefits were less evident (and often absent) in participants who had primary neurologic, psychiatric, or sleep disorders, and virtually no benefit was observed in healthy individuals. Among RCTs, only 7 of 19 demonstrated significant improvements in sleep, and similarly, 7 of 12 non-randomized studies reported positive sleep-related outcomes. 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.
