Anxiety, Sleep, and Medical Cannabis Research

Understanding the Current Landscape of Cannabis and Health

This roundup features studies from PubMed — the U.S. National Library of Medicine's database of peer-reviewed research. These reports offer a snapshot of how researchers are currently studying the use of cannabinoids for various conditions.

Current Usage and FDA Approvals

A review published in JAMA (PubMed) notes that about 27% of adults in the U.S. and Canada report using cannabis for medical purposes. A significant portion also uses cannabidiol (CBD), a non-psychoactive compound. Currently, the FDA has approved cannabinoid use for specific conditions, including HIV/AIDS-related anorexia, chemotherapy-induced nausea and vomiting, and certain pediatric seizure disorders.

Research on Mental Health and Anxiety

Several reviews highlight the complexity of cannabis for mental health. A study in JAMA Internal Medicine (PubMed) reports that many people turn to cannabis for mental health symptoms, but clear benefits have yet to be established and adverse effects are possible. Similarly, a systematic review and meta-analysis in The Lancet Psychiatry (PubMed) found that while cannabinoids are a major reason for medical approval, their efficacy and safety as a primary treatment for mental disorders are still being evaluated.

The British Journal of Clinical Pharmacology (PubMed) also describes how cannabinoids are being explored for chronic pain, depression, epilepsy, and anxiety. Additionally, that review highlights the important need to understand how cannabinoids may interact with other drugs — an essential consideration for safety.

Risk Factors and Newer Research on Anxiety Relief

Research also looks at risk factors. A study in JAMA Health Forum (PubMed) examined how adolescent cannabis use is associated with an increased risk of several psychiatric disorders, including psychotic, bipolar, depressive, and anxiety disorders.

More recent research offers a different look at how cannabis may affect anxiety on a daily basis. A study in the International Journal of Environmental Research and Public Health (PubMed) compared flower and edible cannabis products. The researchers observed that while CBD may have anxiolytic effects, THC is often linked to increased anxiety, and the daily impact of cannabis use on anxiety remains unclear.
