Abstract

Purpose of Review Global policy changes have increased access to products containing cannabidiol (CBD), a primary constituent of hemp and cannabis. The CBD product industry has experienced tremendous growth, in part, because CBD is widely touted as an effective therapeutic for myriad health conditions. However, only 1 CBD product (Epidiolex®) has been approved by the US Food and Drug Administration (FDA) to date. There is substantial interest among consumers and the medical and scientific communities regarding the therapeutic potential of CBD, including for indications that are not recognized by the FDA. The purpose of this review was to synthesize available evidence from clinical research regarding the efficacy of CBD as a therapeutic. Recent Findings Human laboratory studies and clinical trials (e.g., randomized controlled trials and single-arm, open-label trials) evaluating the efficacy of CBD as a therapeutic were identified for various medical conditions, including epilepsy, anxiety, pain/inflammation, schizophrenia, various substance use disorders, post-traumatic stress disorder, and others. There is clear evidence supporting the utility of CBD to treat epilepsy. For other health conditions reviewed, evidence was often mixed and/or there was a general lack of well-powered randomized, placebo-controlled studies to draw definitive conclusions. Summary Rigorous, controlled evidence for the therapeutic efficacy of CBD is lacking for many health conditions. Possible concerns with the use of CBD as a therapeutic include the potential for adverse effects (e.g., liver toxicity), drug-drug interactions, and lack of sufficient regulatory oversight of retail CBD products.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CBD has fewer safety concerns than THC.

    “CBD is not intoxicating and has fewer safety concerns than THC, but there is the potential for liver toxicity, drug-drug interactions, and there is poor regulatory oversight of CBD products [105].”

    From Cannabis, cannabinoids and health: a review of evidence on risks and medical benefits (2025) · cites this paper as [105]

    The Concluding Remarks describe CBD as having low toxicity, no psychotomimetic effects, and a favorable safety profile, while also discussing adverse effects. They do not compare CBD’s overall safety concerns with THC’s, so the comparative part of the claim is not established by this copy. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
