Cannabidiol (CBD) is one of the most researched cannabinoids from the Cannabis sativa plant. The other well-known cannabinoid is tetrahydrocannabinol (THC). Along with CBD and THC, the Cannabis sativa plant contains
Cannabinoids, including CBD and THC, bind to special cannabinoid receptors in the brain.
THC produces the famous ‘high’ feeling that people associate with weed. However, CBD does not produce this effect. Instead, it offers a variety of potential health benefits.
A 2020 systematic review in CNS Drugs found that treatment with CBD reduced seizures in people with Dravet Syndrome, a drug-resistant seizure disorder.
The growing legalization of medical cannabis in the U.S. has prompted many scientists to carry out studies into the various therapeutic uses of cannabis and CBD.
One major question among healthcare professionals is whether CBD can alleviate anxiety disorders.

The authors of the review also found preclinical and clinical evidence that established CBD as an effective treatment for numerous types of anxiety disorders, including:
- generalized anxiety disorder (GAD)
- post-traumatic stress disorder (PTSD)
- panic disorder (PD)
- obsessive-compulsive disorder (OCD)
- social anxiety disorder (SAD)

All groups reported improvements in their overall quality of life after 3 weeks of CBD treatment. The individuals who received CBD treatment for anxiety or depression reportedly experienced improvements in their ability to perform daily functions and reduce pain and anxiety or depression symptoms.
70% of study participants reported some level of satisfaction with CBD treatment, ranging from good to excellent. Only 9.9% of participants experienced adverse side effects, such as sedation and vivid dreams. An even smaller portion of the study population (0.8%) reported worsening symptoms.
The majority of study participants received one 25 milligram capsule of CBD once a day (mg/d). A few participants received 50 or 75 mg/d. One individual with a history of trauma and schizoaffective disorder received up to 175 mg/d.
After the first 2 months of CBD treatment, 78.1–79.2% of participants reported improvements in anxiety symptoms. However, 15.3–19.5% of participants developed worse symptoms after CBD treatment.
The authors of one 2020 article reviewed eight studies investigating CBD’s role in treating various anxiety disorders.
The authors found evidence to support the use of CBD as an effective monotherapy or complementary therapy for treating generalized anxiety disorder, social anxiety disorder, and post-traumatic stress disorder.
However, the studies showed considerable variation in CBD doses, ranging from 6-400 mg per dose. This variation highlights the need for more high-quality, large-scale clinical trials to help establish standardized dosing and clinical usage guidelines for CBD therapy.
How to use
As previously mentioned, researchers and healthcare professionals have yet to establish standardized dosing recommendations for CBD therapy.
In a 2019 study, researchers found that 300–600 mg of CBD significantly reduced anxiety symptoms in 57 adult males.
The dosage that a person takes to relieve anxiety depends on the CBD product and how they administer it.
CBD administration methods include:
- sublingual spray
- vaporized oil or cannabis flowers
The administration method determines how quickly cannabinoids begin taking effect.
The effects of orally administered CBD, such as oils, edibles, or capsules, begin working within 30 minutes to 2 hours. Smoking or vaping CBD oil or cannabis buds results in more immediate effects.
People can use oral CBD products to relieve anxiety throughout the day. It may help to take these products in the morning with some food.
Smoking or vaping CBD oil can provide immediate relaxation that may help people during especially stressful events, such as giving a speech.

An ever-growing body of research suggests that CBD may help relieve anxiety, the most common mental health disorder.
However, the FDA do not regulate CBD for treating anxiety. This means that the quality and dosage can vary widely between products and manufacturers.
People who currently use prescription medication or supplements may want to consult a doctor before using CBD.
