BTW, Xanax and all benzos actually stay in system for a long time. Benzos were one of my drugs of choice and they showed up in urine tests for a month, too!! the ones that get out fast are heroin/opiates and cocaine. So much for his brilliant plan. But maybe his plan did show him that changing drugs is like changing seats on the Titanic' he's still going down. Let him leave, and I bet after he's gone a few days you'll realize the extend of your own insanity and how much better it is not to watch him sink.
