Michigan Health Experts Track 123% Rise in Kratom Cases; Warn 7-OH Concentrates Drive the Crisis

Why it matters

Michigan health providers are seeing a 123% surge in kratom-related EMS cases over six months, and clinicians stress that synthetic 7-OH concentrates present far greater danger than natural kratom leaf. As the state Senate weighs a full ban, experts say differentiating the two is essential for effective policy.

The big picture

Michigan's House passed kratom ban legislation in March 2026, sending the debate to the Senate. A recent overdose death in Marquette County involving a kratom derivative product has intensified public scrutiny. Nationally, more than 5 million Americans report using kratom and poison center calls have surged more than 1,200% since 2015.

Key findings

• Michigan EMS recorded 116 kratom-related medical cases in the six months after tracking began, up from 52 in the comparable prior period—a 123% increase.
• Health experts stress a critical distinction: natural kratom leaf carries lower risk than synthetic 7-OH concentrates, which can be 10–13 times more potent than morphine.
• Most patients presenting at treatment centers use kratom to manage pain or opioid withdrawal, complicating simple prohibition arguments.
• Michigan House has passed a ban bill; the Senate has not yet acted, leaving the state in a regulatory gap.
• Standard drug tests do not detect kratom or 7-OH, making clinical screening and court monitoring difficult.

What they say

"Kratom [leaf] and 7-OH are different animals," Michigan health experts told TV6. "The product that's landing people in the emergency room is the concentrated extract, not the dried leaf. We need to be precise about what we're regulating."

Bottom line

Michigan's 123% jump in kratom EMS cases underscores the urgency of distinguishing natural leaf from synthetic 7-OH in both clinical practice and any new legislation.
