Key Takeaways

  • Cannabidiol (CBD) appears to alleviate anxiety in 79.2% of patients within one month of usage. The improvement remains for as long as the patient keeps taking CBD
  • CBD may improve sleep quality in 66.7% of patients throughout the first month of usage. This improvement may fluctuate over time
  • CBD is generally well-tolerated, side effects are rare.

Actions to Consider

  • If you suffer from anxiety, consider taking 25 mg of CBD every morning after breakfast
  • If you want to improve sleep quality, consider taking 25 mg of CBD every evening after dinner
  • If needed, you can gradually increase your daily CBD dosage up to 175 mg per day

Inner peace and healthy sleep are essential for a long life and strong health.

CBD, a non-psychoactive phytochemical from the Cannabis sativa plant, could help you improve your sleep and alleviate anxiety in a safe way. CBD reportedly has fewer side effects than conventional sleep and anti-anxiety medications, but does it work?

In today’s summary, we’ll take a look at one study that may help shed some light on the matter.

What is this study about?

Today’s study is a large case series published in 2019 in the Permanente Journal. The goal of the paper was to evaluate the effectiveness of cannabidiol (CBD) in the treatment of anxiety disorders and sleep issues in 103 adult patients.

Side effects you should know about

The final sample of the study included 72 adults. Two of them stopped taking CBD due to reported fatigue during the first week of treatment, and three adults reported mild sedation that subsided within the first two weeks. One person reported dry eyes.

The right dose, at the right time

In the current study, patients took 25 mg of CBD in the mornings after breakfast if anxiety was their primary concern. If their main trouble was sleep quality, they took 25 mg of CBD in the evening after dinner. If needed, the dosage may be gradually increased, up to a dose of 175 mg per day, according to this study.


The universal hype around CBD is a few steps ahead of the available scientific evidence. So far, major health authorities (like the FDA or the WHO) haven’t officially confirmed and reported any health benefits. Individual studies, however, bring encouraging results.

For instance, the study we looked into today suggests that CBD may be fairly effective for improving sleep quality and alleviating anxiety in adult patients, with effective doses starting at 25 mg daily.
