I have chronic pain and have to see a pain specialist. This weekend we went camping with friends and 1 I didn t know. I have an ecig, but it does not contain nicotine (used to be a smoker). Just habit I guess. The unknown person had an ecig too. We talked about E liquid... I asked if he wanted to try mine. He did and I asked to try his. I didn t know it contain thc oil... needless to say I took 1 puff and knew something was not right. Then he told me...this was Friday night...I have to do a urine test Tuesday at 3:00. Is it likely it s still in my system? I drink only water and hot tea...I am 5 3 and weigh 150lbs. I eat clean and juice daily. I have had to take lactulose for terrible OIC..so it s no long term. Obviously this is not the norm, but worried. Just need advice, I think I could tell my Doc, have had the chronic pain for 10 years.
