Why Kratom Is Illegal in Some States But Legal in Others

Kansas Governor Laura Kelly signed a law in April 2026 that bans kratom — a plant from Southeast Asia that some people use to manage pain or opioid withdrawal. This move puts Kansas in a growing group of states cracking down on kratom, but the picture across the country is messy. Some states ban it outright. Others allow it under strict rules. One state even reversed course and legalized it again. There is no clear federal answer yet, which leaves sellers and users confused.

Kratom itself is not scheduled as a controlled substance at the federal level, meaning the FDA has not officially classified it as a drug. But states are not waiting. Louisiana banned kratom in August 2025. Iowa's House passed a bill that would treat kratom like heroin or LSD — a Schedule I offense, meaning even a first offense could mean criminal charges. Rhode Island, meanwhile, went the opposite direction: in July 2025, it reversed its own ban after users argued kratom helped them quit opioids.

The National Institute on Drug Abuse acknowledges that people do use kratom to manage opioid withdrawal, though it notes there are no FDA-approved medical uses for kratom. The American Psychiatric Association took a harder line in October 2025, stating that kratom contains opioid-like compounds and carries risk of addiction and dependence.

How States Are Actually Enforcing the Rules

Without a federal ban, states are getting creative. Missouri's Attorney General struck a deal with American Shaman, a major kratom and hemp retailer, to pull kratom products off shelves — not through a court battle, but by using consumer-protection laws. Ohio took a different path: instead of banning kratom, the state required anyone selling it to follow food-safety and labeling rules, the way they would with any dietary supplement.

California has been the most aggressive. In March 2026, Governor Newsom's office announced that it had achieved 95% compliance with its kratom prohibition. That high number suggests the state is actively watching the market, not just hoping the law would enforce itself.

The FDA has raised concerns about kratom over time. The agency has warned that kratom appears to pose risks of addiction and dependence — characteristics similar to opioids. Its testing labs have flagged contamination issues in some products. But the FDA has not moved to ban kratom nationally. Instead, it seems to be gathering evidence before deciding what to do.

The Complication: One Alkaloid Matters More Than Others

Kratom contains several active compounds, called alkaloids. One of them, called 7-hydroxymitragynine (or 7-OH), is far more potent at opioid receptors — the brain targets that opioids affect — than the main alkaloid in kratom. Several states, including California, Missouri, and Iowa, have specifically named 7-OH in their bans or rules. This matters because companies could once dodge restrictions by tweaking a product's formula. By naming this particular alkaloid, states are trying to close that loophole.

Why This Patchwork Creates Real Problems

For a company selling kratom across multiple states, compliance is now a headache. A product that is legal in Ohio under food-safety rules might be illegal in Kansas or California. Consumers face the same confusion. And the absence of a federal decision leaves state lawmakers in the dark, forced to choose between warnings from health agencies, reports from users about real relief, and pressure from the kratom industry.

Rhode Island's reversal suggests there is tension here — people argue kratom helps them, and some lawmakers listen. But Iowa and Missouri point the other way. The stronger trend, at least for now, is toward tightening rules.

The root cause is federal inaction. Until the FDA or DEA takes a clear stand — either scheduling kratom or approving a medical use for it — states will keep making their own calls. That uncertainty is likely to push more legislatures toward restriction, if only because it feels like the safer choice for a politician. But Rhode Island's example shows that if kratom users mobilize and make their case persuasively, a state can reverse course.
