So I just had a strange experience . Went to a new doctor for pain management . After a bunch of questions he asked me to pee in a cup . I told him I could give him my drug test results for the hospital last month and they would be exactly the same but he insisted . So here is the strange part . I fill the cup and give it to him he looks at it stares for a second and says "you smoke Marijuana" How the hell could he tell form just looking at it ? Is this some new technology I am not aware of ? Anyone ever have a similar experience ? Maybe he was just fucking with me ?
