St. Clair Shores, Michigan Passes Kratom Age-21 Ordinance; Judge Says Drug Courts Can't Test for Kratom

Source: St. Clair Shores Sentinel

Why it matters

With Michigan's legislature considering a complete kratom ban, cities are adopting interim ordinances. A district court judge's revelation that standard drug tests cannot detect kratom highlights a critical gap in addiction treatment and court supervision programs — one that local age-restriction ordinances alone cannot fix.

The big picture

Michigan's House has passed a bill to ban kratom entirely, with the Senate now considering the measure. Dozens of southeast Michigan communities are enacting local regulations in the interim. Drug courts nationwide face a systemic challenge: kratom binds to opioid receptors but typically does not appear on standard urine drug screens, allowing patients to substitute kratom for opioids while technically passing mandated testing.

Key findings

What they say

"One of the most difficult things with our drug court is the use of kratom because we can't test for it," said 40th District Court Judge Mark Fratarcangeli. "It's a substitute for opioids and it was running rampant."

Bottom line

A Michigan judge's admission that drug courts cannot detect kratom with standard tests reveals a system-wide blind spot: patients in court-mandated addiction treatment can substitute kratom for opioids and go undetected, undermining recovery programs nationwide.
