Cannabis Use and Risk of Chronic Rhinosinusitis and Sinus Surgery

Austin J. Lee, Michael W. Liu, David C. Kaelber, Mohamad R. Chaaban (November 2025)

While cannabis' link to asthma is well-studied, its impact on CRS is less clear. This study explores the association between cannabis use and rates of new-onset chronic rhinosinusitis (CRS), chronic rhinosinusitis with nasal polyps (CRSwNP), and functional endoscopic sinus surgery (FESS) rates.

Patients with cannabis use demonstrated significantly reduced risks in new-onset diagnoses of CRS and FESS compared to non-users. Further studies are warranted to examine the cause of this relationship.
