Is cbd oil good for anxiety and sleep

In recent years, the use of marijuana and CBD for the treatment of a variety of conditions has risen significantly. Specifically, CBD has been found to have potential health benefits for symptoms like insomnia. Here’s a little background on what CBD is and how it impacts your sleep and body.

What Are Cannabinoids and CBD?

Cannabinoids are chemical compounds that bind or attach to certain receptors in the central nervous system and act as chemical messengers. Depending on the specific cannabinoid, it may have varied effects on the body.

The most well-known and probably most researched cannabinoids include cannabidiol (CBD) and tetrahydrocannabinol (THC). We know that THC is the cannabinoid that leads to the “buzz or high” from cannabis use.

CBD differs from THC and does not cause psychoactive effects or a “high.” Because it does not cause the psychoactive effects and it might help certain conditions, such as pain, anxiety, and insomnia, CBD is gaining traction as a possible treatment for several diseases.

How Do CBD and Cannabinoids Work?

Not everything is completely understood about how cannabinoids (including CBD) work. What we do know from research is that CBD and cannabinoids interact with proteins and cells in the brain. A relatively newly discovered system may also hold some answers.

The Endocannabinoid System and Sleep

Researchers discovered that the endocannabinoid system plays a role in maintaining certain body functions, such as mood, appetite, sleep, and regulating circadian rhythms. Within the endocannabinoid system is a network of cannabinoid receptors in the brain and central nervous system.The two primary receptors identified are CB1 and CB2.

Cannabinoids attach to these cells and have various effects. As far as how they may affect sleep, some research indicates that the cannabinoid CBD may interact with specific receptors, potentially affecting the sleep/wake cycle.

Additionally, CBD may also decrease anxiety and pain, which can both interfere with restful sleep. By reducing certain symptoms, it’s also possible that sleep may improve.

What Does the Research Say About CBD?

Although more studies need to be performed, some research supports the theory that CBD and cannabinoids may improve sleep. This study published in the journal, Medicines, involved 409 people with insomnia. Data was collected from June 2016 to May 2018. Participants rated their symptoms of insomnia on a scale of 1 to 10 with 10 being the most severe. Starting symptoms were rated 6.6 on average.

The participants were treated using the cannabis flower with varied combustion methods including vape, pipe, and joint. THC potency on average was 20 percent and limited to 30 percent. CBD potency was on average 5.7 percent and limited to 30 percent. After using cannabis, participants rated symptoms on average to be 2.2, which was a decrease of 4.5.

The results indicated the cannabinoids in cannabis decreased symptoms of insomnia. But the study involved using the cannabis flower, which contains several cannabinoids. It’s difficult to determine if relief from insomnia was due to CBD or another cannabinoid.

In another study published in the Permanente Journal, 72 adults with anxiety and poor sleep were involved. The participants completed anxiety and sleep assessments at the start of the study and at the first-month follow up. Study participants were given 25 mg of CBD in capsule form. Those that predominantly had sleep complaints took the dose in the evening. Participants that had anxiety as their predominant complaint took CBD in the morning.

After the first month, anxiety scores decreased in 79 percent of the people. Sleep scores improved in 66 percent of the participants, which indicated less trouble sleeping. The results suggest that CBD decreased sleep difficulties in many of the participants. But while the decrease in anxiety symptoms remained steady for the duration of the study, the sleep scores fluctuated over time.

Several smaller studies have also supported the use of CBD oil to improve sleep. For example, a case study involving a 10-year-old girl with post-traumatic stress disorder and poor sleep was treated with CBD. A trial of 25 mg of a CBD supplement was administered at bedtime. An additional 6 to 12 mg of CBD was given via a sublingual spray during the day for anxiety. Sleep quantity and quality gradually improved over five months.

Though there is plenty of supporting evidence that shows CBD and cannabinoids can improve sleep, the results are not conclusive and more research needs to be done.

Forms of CBD

CBD is extracted from the cannabis plant and known as CBD oil. But it can be a little complicated. CBD may be extracted from either the marijuana or hemp plant, which are both strains of the Cannabis sativa plant. But they are harvested differently. Hemp comes from the seeds and stalks of the plant, which contains less THC than marijuana.

Because the THC content in CBD oil may vary, depending on the state it’s sold, there may be restrictions. For example, in some states, CBD oil is sold legally if all of the THC is removed. If CBD oil still contains THC or other cannabinoids, it may only be sold in states that have legalized marijuana use.

Depending on the laws in your state, you may need a doctor’s prescription for CBD oil. But laws continue to change quickly, so in the near future, it may be different.

CBD oil can be placed under the tongue. It may also be infused in different products including the following;

  • Edibles: Various types of edibles infused with CBD oil are available including gummy bears, cakes, and cookies. Edibles usually list the concentration of CBD in milligrams.
  • Vaporing: CBD extract can be used in a vaporizer or vape pen. As the extract heats up, it creates a vapor that is inhaled.
  • Tinctures: CBD also comes in tinctures. A few drops of the liquid can be added to drinks.

CBD oil is available in different concentrations. Since research is ongoing, the exact dose to treat sleep issues may not be fully known. It might take some trial and error to determine what works best.

Because there are so many different ways to ingest CBD, there are tons of CBD products to choose from. If you aren’t sure where to start, here are the CBD products we recommend to try if you want to improve your sleep.

Overall, there is scientific research that supports the theory that there are CBD health benefits. While more research needs to be done, the use of CBD can potentially decrease your symptoms of insomnia and help you get more quality sleep. If you struggle with sleep issues, the best first step is to consult your doctor and learn more about causes and treatments.

Cannabidiol in Anxiety and Sleep: A Large Case Series

Cannabidiol (CBD) is one of many cannabinoid compounds found in cannabis. It does not appear to alter consciousness or trigger a “high.” A recent surge in scientific publications has found preclinical and clinical evidence documenting value for CBD in some neuropsychiatric disorders, including epilepsy, anxiety, and schizophrenia. Evidence points toward a calming effect for CBD in the central nervous system. Interest in CBD as a treatment of a wide range of disorders has exploded, yet few clinical studies of CBD exist in the psychiatric literature.

Objective

To determine whether CBD helps improve sleep and/or anxiety in a clinical population.

Design

A large retrospective case series at a psychiatric clinic involving clinical application of CBD for anxiety and sleep complaints as an adjunct to usual treatment. The retrospective chart review included monthly documentation of anxiety and sleep quality in 103 adult patients.

Main Outcome Measures

Sleep and anxiety scores, using validated instruments, at baseline and after CBD treatment.

Results

The final sample consisted of 72 adults presenting with primary concerns of anxiety (n = 47) or poor sleep (n = 25). Anxiety scores decreased within the first month in 57 patients (79.2%) and remained decreased during the study duration. Sleep scores improved within the first month in 48 patients (66.7%) but fluctuated over time. In this chart review, CBD was well tolerated in all but 3 patients.

Conclusion

Cannabidiol may hold benefit for anxiety-related disorders. Controlled clinical studies are needed.

INTRODUCTION

The Cannabis plant has been cultivated and used for its medicinal and industrial benefits dating back to ancient times. Cannabis sativa and Cannabis indica are the 2 main species.1 The Cannabis plant contains more than 80 different chemicals known as cannabinoids. The most abundant cannabinoid, tetrahydrocannabinol (THC), is well known for its psychoactive properties, whereas cannabidiol (CBD) is the second-most abundant and is nonpsychoactive. Different strains of the plant are grown containing varying amounts of THC and CBD. Hemp plants are grown for their fibers and high levels of CBD that can be extracted to make oil, but marijuana plants grown for recreational use have higher concentrations of THC compared with CBD.2 Industrial hemp must contain less than 0.3% THC to be considered legal, and it is from this plant that CBD oil is extracted.3

Many different cultures have used the Cannabis plant to treat a plethora of ailments. Practitioners in ancient China targeted malaria, menstrual symptoms, gout, and constipation. During medieval times, cannabis was used for pain, epilepsy, nausea, and vomiting, and in Western medicine it was commonly used as an analgesic.4,5 In the US, physicians prescribed Cannabis sativa for a multitude of illnesses until restrictions were put in place in the 1930s and then finally stopped using it in 1970 when the federal government listed marijuana as a Schedule I substance, claiming it an illegal substance with no medical value. California was the first state to go against the federal ban and legalize medical marijuana in 1996.6 As of June 2018, 9 states and Washington, DC, have legalized recreational marijuana, and 30 states and Washington, DC, allow for use of medical marijuana.7 The purpose of the present study is to describe the effects of CBD on anxiety and sleep among patients in a clinic presenting with anxiety or sleep as a primary concern.

CBD has demonstrated preliminary efficacy for a range of physical and mental health care problems. In the decade before 2012, there were only 9 published studies on the use of cannabinoids for medicinal treatment of pain; since then, 30 articles have been published on this topic, according to a PubMed search conducted in December 2017. Most notable was a study conducted at the University of California, San Diego’s Center for Medicinal Cannabis Research that showed cannabis cigarettes reduced pain by 34% to 40% compared with placebo (17% to 20% decrease in pain).8 In particular, CBD appears to hold benefits for a wide range of neurologic disorders, including decreasing major seizures. A recent large, well-controlled study of pediatric epilepsy documented a beneficial effect of CBD in reducing seizure frequency by more than 50%.9 In addition to endorphin release, the “runner’s high” experience after exercise has been shown to be induced in part by anandamide acting on CB1 receptors, eliciting anxiolytic effects on the body.10 The activity of CBD at 5-HT1A receptors may drive its neuroprotective, antidepressive, and anxiolytic benefits, although the mechanism of action by which CBD decreases anxiety is still unclear.11 CBD was shown to be helpful for decreasing anxiety through a simulated public speaking test at doses of 300 mg to 600 mg in single-dose studies.12–14 Other studies suggest lower doses of 10 mg/kg having a more anxiolytic effect than higher doses of 100 mg/kg in rats.15 A crossover study comparing CBD with nitrazepam found that high-dose CBD at 160 mg increased the duration of sleep.16 Another crossover study showed that plasma cortisol levels decreased more significantly when given oral CBD, 300 to 600 mg, but these patients experienced a sedative effect.17 The higher doses of CBD that studies suggest are therapeutic for anxiety, insomnia, and epilepsy may also increase mental sedation.16 Administration of CBD via different routes and long-term use of 10 mg/d to 400 mg/d did not create a toxic effect on patients. Doses up to 1500 mg/d have been well tolerated in the literature.18 Most of the research done has been in animal models and has shown potential benefit, but clinical data from randomized controlled experiments remain limited.

Finally, the most notable benefit of cannabis as a form of treatment is safety. There have been no reports of lethal overdose with either of the cannabinoids and, outside of concerns over abuse, major complications are very limited.19 Current research indicates that cannabis has a low overall risk with short-term use, but more research is needed to clarify possible long-term risks and harms.

Given the promising biochemical, physiologic, and preclinical data on CBD, a remarkable lack of randomized clinical trials and other formal clinical studies exist in the psychiatric arena. The present study describes a series of patients using CBD for treatment of anxiety or sleep disturbances in a clinical practice setting. Given the paucity of data in this area, clinical observations can be quite useful to advance the knowledge base and to offer questions for further investigation. This study aimed to determine whether CBD is helpful for improving sleep and/or anxiety in a clinical population. Given the novel nature of this treatment, our study also focused on tolerability and safety concerns. As a part of the evolving legal status of cannabis, our investigation also looked at patient acceptance.

METHODS

Design and Procedures

A retrospective chart review was conducted of adult psychiatric patients treated with CBD for anxiety or sleep as an adjunct to treatment as usual at a large psychiatric outpatient clinic. Any current psychiatric patient with a diagnosis by a mental health professional (psychiatrist, psychiatric nurse practitioner, or physician assistant) of a sleep or anxiety disorder was considered. Diagnosis was made by clinical evaluation followed by baseline psychologic measures. These measures were repeated monthly. Comorbid psychiatric illnesses were not a basis for exclusion. Accordingly, other psychiatric medications were administered as per routine patient care. Selection for the case series was contingent on informed consent to be treated with CBD for 1 of these 2 disorders and at least 1 month of active treatment with CBD. Patients treated with CBD were provided with psychiatric care and medications as usual. Most patients continued to receive their psychiatric medications. The patient population mirrored the clinic population at large with the exception that it was younger.

Nearly all patients were given CBD 25 mg/d in capsule form. If anxiety complaints predominated, the dosing was every morning, after breakfast. If sleep complaints predominated, the dosing was every evening, after dinner. A handful of patients were given CBD 50 mg/d or 75 mg/d. One patient with a trauma history and schizoaffective disorder received a CBD dosage that was gradually increased to 175 mg/d.

Often CBD was employed as a method to avoid or to reduce psychiatric medications. The CBD selection and dosing reflected the individual practitioner’s clinical preference. Informed consent was obtained for each patient who was treated and considered for this study. Monthly visits included clinical evaluation and documentation of patients’ anxiety and sleep status using validated measures. CBD was added to care, dropped from care, or refused as per individual patient and practitioner preference. The Western Institutional Review Board, Puyallup, WA, approved this retrospective chart review.

Setting and Sample

Wholeness Center is a large mental health clinic in Fort Collins, CO, that focuses on integrative medicine and psychiatry. Practitioners from a range of disciplines (psychiatry, naturopathy, acupuncture, neurofeedback, yoga, etc) work together in a collaborative and cross-disciplinary environment. CBD had been widely incorporated into clinical care at Wholeness Center a few years before this study, on the basis of existing research and patient experience.

The sampling frame consisted of 103 adult patients who were consecutively treated with CBD at our psychiatric outpatient clinic. Eighty-two (79.6%) of the 103 adult patients had a documented anxiety or sleep disorder diagnosis. Patients with sole or primary diagnoses of schizophrenia, posttraumatic stress disorder, and agitated depression were excluded. Ten patients were further excluded because they had only 1 documented visit, with no follow-up assessment. The final sample consisted of 72 adult patients presenting with primary concerns of anxiety (65.3%; n = 47) or poor sleep (34.7%; n = 25) and who had at least 1 follow-up visit after CBD was prescribed.

Main Outcome Measures

Sleep and anxiety were the targets of this descriptive report. Sleep concerns were tracked at monthly visits using the Pittsburg Sleep Quality Index. Anxiety levels were monitored at monthly visits using the Hamilton Anxiety Rating Scale. Both scales are nonproprietary. The Hamilton Anxiety Rating Scale is a widely used and validated anxiety measure with 14 individual questions. It was first used in 1959 and covers a wide range of anxiety-related concerns. The score ranges from 0 to 56. A score under 17 indicates mild anxiety, and a score above 25 indicates severe anxiety. The Pittsburg Sleep Quality Index is a self-report measure that assesses the quality of sleep during a 1-month period. It consists of 19 items that have been found to be reliable and valid in the assessment of a range of sleep-related problems. Each item is rated 0 to 3 and yields a total score from 0 to 21. A higher number indicates more sleep-related concerns. A score of 5 or greater indicates a “poor sleeper.”

Side effects and tolerability of CBD treatment were assessed through spontaneous patient self-reports and were documented in case records. Any other spontaneous comments or complaints of patients were also documented in case records and included in this analysis.

Data Analysis

Deidentified patient data were evaluated using descriptive statistics and plotted graphically for visual analysis and interpretation of trends.

RESULTS

The average age for patients with anxiety was 34 years (range = 18–70 years) and age 36.5 years for patients with sleep disorders (range = 18–72 years). Most patients with an anxiety diagnosis were men (59.6%, 28/47), whereas more sleep-disordered patients were women (64.0%, 16/25). All 72 patients completed sleep and anxiety assessments at the onset of CBD treatment and at the first monthly follow-up. By the second monthly follow-up, 41 patients (56.9%) remained on CBD treatment and completed assessments; 27 patients (37.5%) remained on CBD treatment at the third monthly assessment.

Table 1 provides means and standard deviations for sleep and anxiety scores at baseline and during the follow-up period for adults taking CBD. Figure 1 graphically displays the trend in anxiety and sleep scores over the study period. On average, anxiety and sleep improved for most patients, and these improvements were sustained over time. At the first monthly assessment after the start of CBD treatment, 79.2% (57/72) and 66.7% (48/72) of all patients experienced an improvement in anxiety and sleep, respectively; 15.3% (11/72) and 25.0% (18/72) experienced worsening symptoms in anxiety and sleep, respectively. Two months after the start of CBD treatment, 78.1% (32/41) and 56.1% (23/41) of patients reported improvement in anxiety and sleep, respectively, compared with the prior monthly visit; again, 19.5% (8/41) and 26.8% (11/41), respectively, reported worsening problems as compared with the prior month.
