I recently had a young patients who admittedly used many drugs---nicotine, alcohol, marijuana, meth, cocaine. He was admitted and among his belongings was a full bottle of Visine. I asked him what he used them for--expecting that he would say to help with the 'druggy' eyes---but he said it was to help him "not pee hot". I hadn't heard about it's supposed benefit of making a urine drug screen 'clean'. Anybody else heard that?
