Michigan House Advances Complete Kratom Ban; Debate Centers on Synthetic vs. Natural Alkaloids

Why it matters

Michigan lawmakers are voting on whether to ban kratom entirely or only synthetic derivatives, affecting millions of consumers and treatment options for people managing opioid withdrawal.

The big picture

Michigan joins a growing list of states advancing kratom restrictions, but debate remains on whether to target all kratom or just concentrated 7-OH products. The FDA moved in July 2025 to classify synthetic 7-OH as Schedule I, but has not yet formally added it to controlled substance lists nationally. Meanwhile, 47 U.S. deaths have been linked to kratom use, though experts disagree on whether the natural plant or synthetic derivatives pose the greater risk.

Key findings

• Michigan House voted 56-48 on March 18 to ban all kratom sales; Democrats argue outright bans lack evidence and proper hearing. 7-hydroxymitragynine (7-OH), a synthetic alkaloid, is described as 50-100x more potent than natural kratom leaf and shows opioid-like effects. Michigan has no age restrictions; some retailers voluntarily enforce 21+ policies, but no federal ID requirement exists for kratom purchases. Eight states now have outright kratom bans; Ohio has banned synthetic forms while natural kratom remains legal. Withdrawal from kratom is compared by clinicians to "the worst influenza of your life—times 10" and includes insomnia, anxiety, and psychiatric episodes.

What they say

Kratom users, substance abuse counselors and doctors report symptoms of dependence and withdrawal from the substance, particularly when users exceed the recommended serving size. — Detroit News, based on interviews with University of Michigan researchers

Bottom line

**Michigan lawmakers face a policy choice between banning all kratom or only synthetic 7-OH, with limited clinical data on long-term safety but emerging evidence of withdrawal and dependence.**
