How is cbd oil used for anxiety and insomnia

CBD and Sleep

The popularity of cannabidiol, or CBD, has exploded over the last few years. CBD seems to be everywhere, in everything from capsules to coffee. Sales of the compound are expected to increase by forty times in the next three years. CBD is now legal in all fifty states, and can be purchased online and in shops across the country.

CBD has been heralded as a remedy for a wide range of health concerns, including insomnia. Though the science is limited and conflicting, there is increasing evidence that CBD may indeed impact sleep. What does the latest research say about CBD for sleep? Does it make sleep easier or more difficult? And is it safe to take?


First discovered in 1940, cannabidiol makes up 40% of the extract available in cannabis and hemp plants.

What is CBD?

Cannabidiol, commonly referred to as CBD, is a natural compound found in the flower of the cannabis plant. Cannabis contains more than a hundred phytocannabinoids, or natural chemical compounds. Most of these are found in the resinous substance produced by the plant’s fine, crystal-like trichomes, or hairs.

CBD is typically derived from industrial hemp, which contains less resin than cannabis. The term “hemp” is used to describe types of cannabis that contain 0.3% THC or less. Marijuana-derived CBD is available only in states where growing psychoactive cannabis is legal, such as Colorado.

Though CBD is closely related to perhaps the most famous phytocannabinoid, tetrahydrocannabinol (THC), the two compounds act in different ways and target different receptors in the brain and body. CBD is not psychoactive, and does not cause the intoxication that THC is known for. CBD is consumed in such forms as oils, capsules, gummies, sublingual sprays, and tinctures. It may also be inhaled in vaporized form, or “vaped.”

The CBD Extraction Process

CBD is extracted from hemp or cannabis using one of the following extraction methods:

  • CO2, or pressurized carbon dioxide. Carbon dioxide behaves like a solvent at certain temperatures and pressures, making it possible to extract CBD and other phytocannabinoids without the dangers of chemical solvents. CO2 also removes chlorophyll, which may taste bitter and cause unwanted effects when included in CBD products
  • Ethanol and other solvents. High-grade grain alcohol can be used to extract CBD, but may degrade or destroy the plant’s natural waxes along with their potential health benefits. Other solvents such as butane may damage plant waxes, as well, and do little to remove impurities such as chlorophyll. They may also leave behind residues that are toxic to the body
  • Olive oil. Olive oil of any kind can be used to extract oil from cannabis or hemp plants. Olive oil that contains cannabidiol is perishable and must be stored in a cool, dark place

Q: What does psychoactive mean? A: A psychoactive drug is a substance that alters brain function and perceptions.

CBD’s Effects on the Body

The human body contains a biological system made up of endocannabinoids, specific neurotransmitters that bind to cannabinoid receptors. The endocannabinoid system helps to regulate such essential functions as appetite, mood, fertility, memory, and pain. This system is also associated with the feeling of euphoria that may result from intense exercise.

The two primary endocannabinoid receptors are referred to as CB1 and CB2, and are found in the brain, peripheral organs, and nervous system. CBD influences various receptors both inside and outside the endocannabinoid system, changing how hormones and neurotransmitters behave. These interactions with CBD may have a beneficial effect on such physiological processes as:

Other CBD benefits include a positive effect on seizures, particularly pediatric forms that are otherwise difficult to treat. The CBD-based drug Epidolex was recently approved by the FDA for treating two rare and severe forms of childhood convulsive epilepsy for which there is no other treatment.

CBD Safety and Side Effects

CBD has a very different side effect profile from the other well-known phytocannabinoid, THC. While THC can cause side effects such as hallucinations, anxiety, and hunger due to its psychoactive properties, CBD contains no psychoactive compounds.

Though studies on the side effects of CBD are still scarce, the research that does exist supports CBD as a safe and well-tolerated compound. (2) According to current studies, CBD appears to be non-toxic, and safe in doses up to 1500 milligrams each day. Chronic, long-term use appears safe, as well. (3)

CBD does not seem to impact appetite, blood pressure, heart rate, or body temperature. The movement of food through the GI tract appears unaffected. Though CBD has an impressive safety profile according to existing studies, it is not without certain side effects. Possible side effects of CBD products include:

  • The metabolism of certain kidney medications
  • Effects on fertility and in vitro cell development
  • The activity of proteins in cell membranes that help to transport drugs and other substances
In vitro

Studies of certain CBD-based drugs showed a higher incidence of certain side effects in people who took the drug than in those who didn’t. (4) The side effects noted during research included:

  • Nausea
  • Vomiting
  • Dry mouth
  • Sleepiness
  • Loss of appetite

Some of these effects may be dosage dependent, meaning they are more likely to occur at higher doses. Anti-seizure drugs are made from a particularly potent strain of CBD, and might be more likely to cause reactions than non-pharmaceutical grade CBD products. The full side effect profile of CBD will become clearer as further studies are conducted and anecdotal reports from users are collected.

CBD and Sleep: The Evidence

Research on CBD as a treatment for sleep difficulties as well as other medical conditions is in its infancy. Between 2002 and 2012, there were just nine studies published on the use of CBD to treat pain. The pace of research has picked up in recent years, with over 30 studies published since 2012.

Anecdotal evidence exists for CBD’s positive effect on healthy sleep patterns, but more studies need to be conducted before definitive conclusions can be drawn. However, multiple studies have shown that CBD has a marked influence on anxiety, which may be key to its beneficial impact on sleep. CBD also appears to improve sleep by altering the brain’s perception of pain signals. Pain is one of the most common causes of interrupted sleep, and may be temporary or chronic.

CBD and Anxiety

One recent study showed that CBD’s effects on the central nervous system may calm anxiety and promote healthy sleep. Adult psychiatric patients suffering from anxiety or sleep difficulties rated the effect of 25 milligram capsules of CBD. Though scores for sleep indicated that CBD’s impact was mild, scores were significantly higher for its effects on anxiety. (5)

CBD may have a positive influence on anxiety by changing the way the body processes serotonin, a neurotransmitter associated with well-being and positive emotion. CBD may work in a similar way to the class of antidepressant medications known as serotonin reuptake inhibitors, or SSRIs. SSRIs target the sertonin receptor known as 5-HT1A and increase the amount of serotonin available to the brain. A 2014 study demonstrated that CBD improves 5-HT1A transmission in rats and decreases behavior that indicates anxiety and stress. (6)

Multiple studies reveal CBD’s positive impact on anxiety, which may support the compound’s sleep-promoting effects. (7) Though CBD’s ability to reduce anxiety appears clear, there is some evidence that it may actually promote wakefulness and decrease both slow-wave and REM sleep. (8) Some animal studies show an increase in total sleep time, while others show that it increases wakefulness. (9) (10) (11) The effect may be dosage dependent, or may be different in human beings. More research needs to be done to assess CBD’s direct role on the sleep-wake cycle.

CBD and Pain

Because of CBD’s positive effect on pain perception, it may be helpful for promoting sleep, particularly in people suffering from neuropathic or inflammatory pain such as Crohn’s Disease. The GI tract seems to be particularly responsive to CBD, which may help relieve the nausea and vomiting that accompany some pain conditions and medical treatments. (12)

CBD appears to reduce pain in part by modulating glycine receptors in the central nervous system. Glycine receptors are inhibitory, which means they reduce the perception of pain. CBD may increase the effect of such receptors, relieving pain that can cause insomnia or fragmented sleep. (13)

Research demonstrates CBD’s ability to reduce inflammation through its influence on adenosine, an important neurotransmitter. Adenosine and its receptors are strongly associated with the regulation of inflammation in the body. CBD increases the amount of adenosine available to the brain, thereby impacting the activity of adenosine receptors and reducing inflammation. (14)

How To Use CBD

When considering CBD as a treatment for sleep difficulties or for any other reason, consultation with a physician is always recommended to discuss possible side effects, drug interactions, and dosages.

CBD may be taken in a number of forms, from capsules to vaping. Since usage of the compound is still fairly new, dose titration may be the safest and most effective way to take CBD. Dose titration involves starting at a low dosage and gradually increasing the amount taken to help minimize side effects.

There is currently no recommended dosage of CBD for sleep or any other health concern. To help determine the best starting dosage for you, keep the following in mind:

  • Your individual physiology and body weight. Do you tend to feel the effects of certain medications at low doses? CBD could be similar. If you are larger or heavier, you may need a higher dose of CBD to experience beneficial effects on sleeping patterns, anxiety, or pain
  • The strength of the CBD product. A tincture may be more concentrated than a capsule for example, or vice versa. Vaping a CBD product may deliver more active ingredients in a smaller amount than CBD in a topical form. Some forms of CBD such as capsules may take longer for the body to absorb, delaying its effects or changing its effectiveness. Experimenting with different forms and concentrations of CBD can help determine which product works best for you
  • Tolerance. Some CBD users may develop a tolerance to the compound with regular use, necessitating an increase in dosage or change in how the product is delivered. For example, capsules may stop working over time, while switching to a CBD tincture taken sublingually may be more effective

Last Word From Sleepopolis

In the last few years, CBD oil and other products have become enormously popular. Touted as a treatment for everything from depression to multiple sclerosis, CBD is just beginning to undergo the rigorous research that will either support or refute its reputation as a remedy for many common ailments. Though early research points to positive effects on anxiety, pain, and possibly sleep, only time and more peer-reviewed studies will prove if CBD is as promising as it appears to be.

How is cbd oil used for anxiety and insomnia

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.
