One in 13 people around the world live with an anxiety disorder, making them the most common mental health disorder worldwide, according to the World Health Organization (WHO). For those living with anxiety, finding a safe method for managing symptoms is a critical concern.
Quick-acting anti-anxiety medication, such as Xanax and Valium, may offer instant relief but can become addictive. Long-range anxiety medications, such as Prozac, may help reduce symptoms over time, but don’t work for everyone.
Enter cannabidiol, better known as CBD. CBD has recently captured the spotlight as an alternative or complementary treatment for anxiety.
CBD: Snake oil or powerful anxiety treatment?
Clinical research on CBD as a treatment for anxiety disorders has proliferated in recent years with accumulating evidence pointing to its therapeutic potential.
Although most studies on CBD are preclinical and use animal models, clinical studies using human participants are now emerging.
1 in 13 people around the world live with an anxiety disorder, making them the most common mental health disorder worldwide.
In a double-blind study from 2019, 37 Japanese teenagers with social anxiety disorder (SAD) received 300 mg of CBD oil or a placebo every day for four weeks. The teens were assessed with surveys used to diagnose and measure SAD symptoms. The anti-anxiety properties of CBD reduced symptoms aligned with the disorder, providing relief comparable to Paroxetine, a drug commonly used to treat the condition.
Interestingly, in the follow-up, nine of the seventeen teenagers who received the CBD intervention also declared that they had decided to seek some form of treatment. Teenagers with SAD rarely seek help due to the stigma surrounding the condition and for fear of interacting with therapists.
A 2019 retrospective case study reviewed outpatients at a mental health clinic in Fort Collins, Colorado. Forty-seven of the patients sampled had expressed concerns about anxiety. Over three months, the majority of patients were given 25 mg of CBD daily in addition to treatment.
After the first monthly assessment, 79.2% of patients experienced an improvement in anxiety. After two months, 78.1% of patients reported a further improvement compared with the previous month.
However, there were also patients who reported that the symptoms of their anxiety worsened after taking CBD—15.3% felt their anxiety had become exacerbated after the first month and 19.5% felt their anxiety had worsened further after the second month.
Another study, done in 2018, also suggests that CBD may heighten anxiety. It included a small sample of individuals with paranoid traits and found that CBD exacerbated anxiety among some of the participants. Anxiety was measured through symptoms such as cortisol concentration, heart rate, and systolic blood pressure.
These contradictory findings may be due to factors such as small sample sizes and variations in dosing. CBD is a bidirectional medicine, which means it can cause opposing responses at different doses. We’ll delve deeper into this below.
How should I consume CBD for anxiety?
If you’re curious about using CBD oil as a tool to help manage your anxiety, education is critical. Understanding the pros and cons of the various ingestion methods can help you determine which form of consumption best suits your needs.
Tinctures and oils
CBD tinctures and oils represent a quick, easy, and accurate way to consume CBD. Most tinctures contain CBD in an alcohol base. CBD oils contain CBD extracts infused into a carrier oil, such as coconut or hemp seed oil.
Tinctures and oils are taken using a dropper, which allows you to easily measure intake. The cannabinoid rapidly enters the bloodstream when taken sublingually—results can kick in as quickly as ten minutes and last up to three to four hours.
CBD vape oils
CBD can be vaped using a special pen that vaporizes the oil. At present, the safety of vaping has come under intense scrutiny. A serious lung condition known as VAPI, or EVALI, has hospitalized more than 2,000 people and led to the deaths of 42. The federal Centers for Disease Control has found that most cases have been linked to the use of illicit-market THC vape cartridges tainted with vitamin E oil (tocopheryl-acetate).
CBD vape cartridges purchased in legal state-licensed cannabis stores are highly regulated, while CBD cartridges purchased from other sources are completely unregulated. Proceed with caution when considering any vaping product in an unregulated environment.
CBD can be added to almost every food under the sun. While super easy to consume in this form—and often delicious, particularly as gummies—it may take an hour or more before results are felt.
What’s more, the oral bioavailability of CBD can hinder CBD absorption—when you consume CBD orally, it has to pass through your gastrointestinal tract before it is metabolized by the liver. As a result, a limited quantity of CBD makes it into the circulatory system.
It’s important to also note that the FDA has recently deemed food containing CBD illegal. You’ll have to get CBD edibles in state-licensed adult-use markets.
Smoking provides an almost instantaneous method for enjoying the effects of CBD. Smoking sends the cannabinoid directly to the alveoli of the lungs, and from there, CBD molecules enter the bloodstream for rapid absorption. However, measuring your CBD intake can be tricky when you smoke, and the act of smoking itself can cause lung inflammation.
Dosing CBD for anxiety
If you read the studies cited above, you’ll notice that the dosing varied significantly between them. The teens in the Japanese study were provided with 300 mg of CBD daily, while the outpatients in the Colorado study received 25 mg. Why such a large discrepancy in dose?
As most scientists and clinicians will readily admit, there is no universally recommended dosage for CBD, and, to date, there haven’t been any large-scale clinical trials to inform dosage guidelines. In addition, the FDA is still learning about CBD—such as its cumulative effects on the body—before it decides on how to regulate it.
This doesn’t necessarily mean CBD is unsafe. Existing research already suggests that it appears to be a safe, well-tolerated treatment. If you’re interested in experimenting with CBD to manage your anxiety symptoms, aim for an informed, cautious approach to dosing (which is always a good idea). Below are some dosing considerations.
General dosing tips
Some basic factors that you should consider when devising a CBD dose include:
- Body weight
- Concentration of CBD
- Severity of your anxiety
The concentration of CBD varies between products, and is generally expressed as milligrams (mg) per container.
Your unique body chemistry affects how you respond to CBD.
Once you know the potency of the CBD product you hold, you can use a dosage calculator or an app such as Accugentix to help settle on your perfect dose. Dosage calculators can provide a recommended dose in milligrams based on your body weight and the severity of your symptoms.
Your unique body chemistry also affects how you respond to CBD. Some individuals metabolize medicine faster than others, which can be attributed to genes or lifestyle. If you know that you metabolize medication quickly, it’s possible that you may benefit from a higher dose.
CBD may do different things at different doses, a phenomenon known as bidirectional effects. Overstimulation of the body’s endocannabinoid system may exacerbate symptoms instead of alleviating them.
Additionally, high levels of CBD, such as 300 mg, have been known to promote sleepiness and relaxation. Conversely, low levels of CBD may create an elevating response, inciting wakefulness and alertness. The best way to avoid unwanted bidirectional effects is to follow the adage: start low, go slow.
Start low, go slow
Titration refers to the process of adjusting the dosage of a medication to get its maximum benefits without adverse effects. CBD has been shown to be safe even when taken in high doses (300-600 mg), nonetheless, it’s advisable and more cost-effective to start with a low dose and increase it incrementally, observing how you feel as you go.
This method forces you to pay attention to subtle changes in your body as it responds to the medication. Everyone’s optimal dosage and tolerance is unique, and this process allows you to get acquainted with yours.
