Hello, I understand your concern. Marijuana interacts with most drugs used in anesthesia and studies have shown that patients who are regular marijuana users have higher tolerance for anesthetic drugs, therefore higher doses as well as the addition of other anesthetic drugs are needed for these patients to achieve a satisfactory level of pain reduction. Five times a day makes you a regular user. So I recommend you stop smoking in the two weeks leading to the procedure. Wishing you good luck and all the best.
