Research on cannabidiol oil (CBD oil) is still in its infancy, but there is mounting evidence to suggest that some people can get relief from anxiety. In this article, we examine what CBD oil is and how it may help reduce anxiety symptoms.
What is CBD oil?
CBD oil is extracted from the cannabis plant, and contains chemicals known as cannabinoids. These may bind to receptors in the brain to help relieve symptoms of pain.
Cannabidiol is extracted from cannabis plants and can be used as an oil. CBD oil is rich in chemicals called cannabinoids that bind to specialized receptors in the brain. The best-known cannabinoid is tetrahydrocannabinol (THC), which causes the "high" people feel after using marijuana.
THC, however, is just one of dozens of cannabinoids. Cannabidiol also binds to these receptors but does not produce a high. Proponents argue that cannabidiol oil has many health benefits, ranging from slowing the growth of cancer to improved mental health.
CBD oil is edible and can be used as a cooking oil or added to food. People may also take it as a medication by consuming a few drops. CBD oil should not be smoked, and there is no evidence that using it as aromatherapy offers any benefits.
Does CBD produce a high?
CBD oil derived from hemp will not produce a "high." Hemp is a type of cannabis plant grown for industrial use, such as making paper and clothing. Unlike other cannabis plants, hemp has not been specially bred to produce high levels of THC.
Cannabidiol may be sold as a type of hemp oil with trace amounts of THC. So, someone using cannabidiol might still test positive for THC on a drug test, even though they will not experience any alterations of mental state after using the oil.
CBD oil and anxiety
Cannabis is known to aid relaxation, making it a popular alternative treatment for those suffer from anxiety.
Much of the research on cannabis products has looked at the use of marijuana rather than at CBD oil as a standalone product. Some studies have found that cannabis might help anxiety. Others suggest that having anxiety is a risk factor for recreational marijuana use, or that using marijuana can make a person more vulnerable to anxiety.
People interested in managing their anxiety with CBD oil should look exclusively at research on cannabidiol, not generalized studies of medical marijuana. Although there are fewer studies on cannabidiol specifically, the preliminary research is promising.
A small 2010 study found that cannabidiol could reduce symptoms of social anxiety in people with social anxiety disorder (SAD). Brain scans of participants revealed changes in blood flow to the regions of the brain linked to feelings of anxiety.
In this study, cannabidiol not only made participants feel better but also changed the way their brains responded to anxiety.
A 2011 study also found that cannabidiol could reduce social anxiety. For that study, researchers looked specifically at cannabidiol to treat anxiety associated with public speaking.
A 2015 analysis of previous studies concluded that CBD oil is a promising treatment for numerous forms of anxiety, including social anxiety disorder, panic disorder, obsessive-compulsive disorder, generalized anxiety disorder, and post-traumatic stress disorder.
The report cautioned, however, that data on long-term use of CBD oil is limited. While research strongly points to the role of cannabidiol in treating short-term anxiety, little is known about its long-term effects, or how it can be used as a prolonged treatment.
A 2016 case study explored whether cannabidiol could reduce symptoms of post-traumatic stress disorder (PTSD) and anxiety-provoked sleep disorder in a child with a history of trauma. Researchers found that cannabidiol reduced the child's anxiety and helped her sleep.
Smoking cannabis may pose more risks to health than using CBD oil.
Research on the use of cannabis suggests that it may have negative health effects, particularly when smoked.
Research specifically on cannabidiol, however, has found few or no negative side effects. This means CBD oil may be a good option for people who do not tolerate the side effects of other medications for anxiety, including addiction.
Not all states in the United States have specifically legalized CBD oil, so a person should educate themselves about the potential risks of purchasing or using it. While CBD oil is not listed on the Controlled Substances Act (CSA), a person should consult their doctor before using it to treat anxiety.
Because CBD oil is not regulated as a medical treatment for anxiety, it is unclear what dosage a person should use, or how frequently they should use it. A person should consult a doctor who has experience with CBD oil to determine the right dosage for their needs.
The role of cannabidiol as a treatment for anxiety disorders remains unclear, as more long-term studies are required to assess the benefits and risks.
For people with anxiety who have gotten no relief from other treatments, however, CBD oil offers a potential alternative solution.
People considering CBD oil for anxiety should speak with a doctor to help determine the right treatment for them. People are also advised to research the laws in their area regarding the use of cannabis products.
