 [ Symptoms ] do surgeons look for marijuana in a urine test during pre admission testing for open hip surgery  i am going to undergo open hip surgery to correct an abnormality before surgery is a pre admission test that they run on patients that include a urine sample i am not a smoker but i did smoke marijuana recently and i was wondering if that would show up in the urine sample or if i should make that aware to my anesthesia doctor that i consult with before hand [ Disease ] due to the fact that you are pregnant your options are limited i would also like to ask what you mean by sinus infection as a symptom i would also like to know if you went to a health care provider for further evaluation and if you were given any medications you can continue to use the neti pot because that is a saline type of solution and safe for you to use if you have sinus congestion or stuffiness however if your sinuses are draining too much that could be causing your cough i would highly recommend talking to your pharmacist and possibly going to see a health care provider for evaluation
