Separate cohorts of patients with pre\u2010existing CRS\u2014with and without cannabis use\u2014were analyzed to evaluate associations with FESS.

There was no difference in risk of CRSwNP at any timepoints. For FESS outcomes, matched cohorts included 5591 patients with pre\u2010existing CRS; cannabis users had lower risk at 1\u2009year (aRR\u2009=\u20090.67, 95% CI 0.47\u20130.96), 2\u2009years (aRR\u2009=\u20090.64, 95% CI 0.46\u20130.88), and 5\u2009years (aRR\u2009=\u20090.69, 95% CI 0.52\u20130.91).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Patients with cannabis use demonstrated significantly reduced risks in new\u2010onset diagnoses of CRS and FESS compared to non\u2010users.
