I’m sure there are some cases where dealers are “lacing” Xanax with fentanyl in the methods described above, but that’s not what’s happening with most of these pills. These are counterfeit pills coming from across the border. They’re being mass produced and made to look like Xanax, Oxycodone and other “downers”, but they’re Fentanyl and in most cases don’t even contain traces of the drugs that they look like. Fake Adderall are being made with meth too.

This recent Statesman article from just a few weeks ago (which was based on a press release), uses the word “laced” here. But what is being described again here is these counterfeit pills.
