I think you're absolutely right. Opioid addiction has been around for a long, long time. I think in the last decade we have seen prescription opioids overtaking heroin on the street as the opioids of choice for addiction because they are so readily available. Recently we've seen a recurrence of heroin addiction, because we actually are being somewhat successful—although I don't think successful enough—at controlling the prescription drugs. But it's not just about prescription drugs—opioid addiction has been around for a long time.
