"Not one pill we've seen in the past year was a real pill."
- Commander Nakamura from the Drugs and Vice Division

From our Podcast: Talking Beat - Drugs in Portland

Commander Art Nakamura of the Drugs and Vice Unit:

"What we are seeing now is a problem with school-age kids buying a drug commonly referred to as Xanax. However, none of the Xanax that we are seeing on the street is actually Xanax. We've got pills that contain fentanyl, other synthetics, such as U-4700, which is so new, it doesn't have a name yet, it has a number. These kids don't know what they're buying. There is an incident in the news where there were multiple kids who purchased Xanax from another student and they all overdosed. Luckily they all survived, but that's a classic example of teenagers purchasing what they thought were Xanax pills but turned out to be something completely else."
