Hepatitis C
Viral infection that causes inflammation and progressive liver damage. Cannabis has insufficient evidence as a treatment for hepatitis C itself, though it is qualifying in several state programs for symptom management during interferon-based regimens, which are now largely obsolete.

What it is
Hepatitis C is a bloodborne viral infection that causes inflammation and, untreated, progressive scarring of the liver leading to cirrhosis and hepatocellular carcinoma. Since the introduction of direct-acting antiviral (DAA) therapies in 2014, hepatitis C is now curable in over 95% of patients with an 8-to-12-week oral regimen, displacing the older interferon- and ribavirin-based treatments.
Cannabis and cannabis-derived therapies
Evidence for cannabis as a treatment for hepatitis C is insufficient. Historically, the qualifying-condition basis was symptom management (nausea, anorexia, fatigue, depression) during the burdensome side-effect profile of interferon-based therapy, which is now obsolete in standard practice.
Hepatitis C remains a qualifying condition under medical cannabis programs in approximately 20 states. The clinical utility of this designation has substantially diminished post-DAA. Patients should pursue evidence-based DAA therapy, which is highly effective, well-tolerated, and curative for most chronic HCV infections.
Frequently asked questions
Does cannabis treat hepatitis C?
No. Cannabis is not a treatment for hepatitis C virus (HCV) infection. Modern direct-acting antiviral (DAA) regimens cure over 95% of patients in 8–12 weeks of oral therapy. Cannabis evidence for hepatitis C is insufficient.
Is any cannabis-derived product FDA-approved for hepatitis C?
No. No cannabis or cannabinoid product is FDA-approved for hepatitis C. The FDA-approved DAA regimens (including combinations such as sofosbuvir/velpatasvir and glecaprevir/pibrentasvir) have transformed hepatitis C into a curable infection.
Why do some state medical-cannabis programs list hepatitis C as a qualifying condition?
Most enumerations date to the interferon era, when patients on interferon-plus-ribavirin regimens experienced severe nausea, fatigue, depression, and anorexia for which cannabis offered symptomatic relief. Since DAA therapies displaced interferon (post-2014), the practical rationale for cannabis-for-hepatitis-C has narrowed substantially.
Are there liver-related concerns when patients with hepatitis C use cannabis?
Yes. Patients with advanced liver disease (cirrhosis) should approach cannabis cautiously: cannabinoids are metabolized hepatically and can interact with antiviral medications and other agents commonly prescribed in liver disease. Smoking compounds known cardiopulmonary risk in patients who may already have advanced liver-disease comorbidities. Disclose cannabis use to the hepatology team.
