CANTON, Mich. - Canton police are cracking down on shops selling kratom and highly concentrated 7-OH products.

Canton Police said an inspection with MDARD and MSP at a Canton-area tobacco shop on August 28, 2026, uncovered hundreds of kratom and 7-OH products, along with hundreds of THC products allegedly being sold illegally.

The items were seized by MDARD, and the case will eventually be referred to the Wayne County prosecutor.

7-OH is short for 7-hydroxymitragynine, a naturally occurring chemical found in the kratom plant. Kratom is a tree native to Southeast Asia. Its leaves contain several alkaloids, including mitragynine, the plant's primary alkaloid, and much smaller amounts of 7-hydroxymitragynine.

Although 7-OH occurs naturally in kratom, it is considered much more potent than mitragynine. It can also be produced or concentrated from kratom extracts. Products labeled as 7-OH may include tablets, gummies, powders, shots, or liquid extracts marketed as kratom products.

7-OH interacts with opioid receptors in the brain and nervous system. Because of that, it can produce opioid-like effects, including relaxation, pain relief, and sedation.

It can also cause unwanted effects such as nausea, vomiting, dizziness, constipation, confusion, and drowsiness.

High doses may increase the risk of slowed breathing, loss of consciousness, and other serious complications, especially when 7-OH is combined with alcohol, prescription opioids, benzodiazepines, or other sedating drugs.

The legal situation is complicated.

Michigan has not enacted a statewide ban specifically making 7-OH illegal.

However, state regulators say kratom and other unapproved psychoactive substances cannot legally be marketed as food or dietary supplement ingredients under current Michigan law.

That is separate from a proposed federal action.

The Drug Enforcement Administration is considering whether to place 7-OH, also known as 7-hydroxymitragynine, under Schedule I of the federal Controlled Substances Act.

That federal change has not taken effect.

For now, Canton police said more local enforcement could follow
