Hello, Cannabis can increase your risk of bleeding as well as increasing other risk factors for surgery including changing blood pressure, heart rate, and possibly interfering with the effects of anesthesia. We typically recommend to avoid using cannabis for up to two weeks before any scheduled surgery or procedure that requires anesthesia. Best of luck!

Curious to know a reference for cannabis having any effect at all on coagulation in a patient not being treated with anticoagulants.
