Has anyone ever failed a drug test for suboxone?

Because of the type of drug it is, it will cause positive drug tests. Suboxone is made of buprenorphrine which is a partial opioid agonist, and naloxone which is an opioid antagonist. My guess would be because agonists bind to the same receptor sites that opioids do, and switch them on, this is why it causes the false positive.

However - Sub. needs to be specifically tested for and will not show up in a 5 or 10 panel screen - that is my experience as I am tested for opiods regularly but the sub does not show up.
