A Clinical Review of Cannabis Therapeutics: What the Evidence Actually Supports
As of 2025, strong evidence supports cannabis for chemotherapy nausea, HIV appetite loss, specific epilepsies, and MS spasticity, while evidence for pain, insomnia, and psychiatric conditions remains mixed.
Quick Facts
What This Study Found
Key established indications include chemotherapy-induced nausea/vomiting, HIV/AIDS appetite loss, Dravet/Lennox-Gastaut/tuberous sclerosis seizures, and MS spasticity. Evidence for chronic pain, insomnia, and psychiatric disorders is inconclusive. Risks include addiction, cognitive impairment in adolescents, CHS, psychosis, perinatal complications, and cardiovascular/pulmonary effects.
Key Numbers
Established indications: 6 conditions with strong evidence. Emerging areas with mixed evidence: chronic pain, insomnia, opioid use disorder, neurological disorders.
How They Did This
Clinical review evaluating current evidence for cannabis and cannabinoid treatment across established and emerging indications, with assessment of known risks and harms.
Why This Research Matters
As public interest in medical cannabis grows, clinicians need a clear evidence-based framework for what cannabis can and cannot do. This review separates established benefits from hype and honestly addresses risks.
The Bigger Picture
The gap between public perception of cannabis as medicine and actual clinical evidence remains significant. This review provides clinicians with the balanced assessment needed to counsel patients who increasingly arrive having already tried cannabis.
What This Study Doesn't Tell Us
Review scope limited to selected conditions. Cannabis research is hampered by historical scheduling restrictions. Evidence quality varies dramatically across conditions.
Questions This Raises
- ?Will improved research access lead to more established indications?
- ?How should clinicians handle the gap between patient experience and clinical evidence?
