Quick Take

May help anxiety or sleep, but effects are inconsistent and interactions are common.

CBD (cannabidiol) is a non-intoxicating cannabinoid found in hemp and cannabis flower extracts; ordinary foods provide negligible amounts. It appears to modulate endocannabinoid signaling and 5-HT1A/TRPV1 pathways, which may affect anxiety, pain, and inflammatory signaling. Human evidence is strongest for anxiety, with smaller, mixed studies for sleep and pain. Adults with anxiety or sleep problems, and some people with chronic pain, are most likely to notice benefit.

How It Works

CBD appears to modulate endocannabinoid signaling, partly by influencing anandamide breakdown, and it also interacts with 5-HT1A and TRPV1 receptors. These pathways can alter anxiety signaling, pain perception, and inflammatory responses.
