This was on the label of a prescription bottle taken from a woman during a welfare check by the police in Pinellas County, Florida. Appearing intoxicated, she admitted she had taken methadone, and when she opened up her purse to get her identification out, the officer noticed the bottle of pills labeled, "Da Stash," and they turned out to be Xanax and not Advil like she claimed. So, I guess it's a slang name that someone put on the pill bottle that contained the illegal drugs (illegal because they weren't prescribed to her).
