it depends on how much came in to your body. if you were breathing the smoke even a little bit you are technically smoking it or breathing it anyway. if it was enough to give you a relief from your pain then it could possibly show up on a test. it could easily be that the small amount you got from second hand smoke was enough to help you but not enough to show on the ua but i'd advise caution if you have to go through those a lot.
i did not believe the second-hand smoke showed positive in a drug screen. does it or not? . my adult grandson is staying with me at this time. he does smoke pot. i have gotten high from only his second hand smoke. by 'high' i mean i fell asleep in my recliner. i have chronic pain and am never without pain. he smoked in same room for two days and i had no pain since i can ever remember. it did not show on a ua. it has been 8+ years since i actually smoked any pot. is there a chance i could show positive even though i do not smoke pot?
