Is Kratom Legal in Wisconsin?

As of late July 2026, no active bills addressing kratom are moving through the Wisconsin legislature. Bill trackers that monitor every state’s drug-related legislation daily haven’t flagged anything new this session. If that changes — say, a bill to legalize or regulate kratom gets introduced — it would show up in legislative databases like LegiScan fairly quickly.

For now, the ban stands as written, with nothing pending to overturn it.

Kratom, the botanical also known scientifically as Mitragyna speciosa, has been illegal in Wisconsin since April 2014. That’s when the state passed Senate Bill 325, a law that added kratom’s two main active compounds — mitragynine and 7-hydroxymitragynine — to Wisconsin’s list of Schedule I controlled substances.

SB 325 came out of the 2013–2014 legislative session and amended Chapter 961 of the Wisconsin Statutes, the state’s version of the Uniform Controlled Substances Act. The bill’s main target wasn’t kratom specifically — it was aimed at synthetic drugs and so-called “designer” substances that were causing concern at the time. Kratom got swept into the same bill alongside various synthetic cannabinoids, even though it’s a natural plant with centuries of traditional use in Southeast Asia, not a lab-made compound.

Schedule I status in Wisconsin means a substance is considered to have high abuse potential and no recognized medical use. Because the law specifically names both mitragynine and 7-hydroxymitragynine — the alkaloids found in every form of kratom — the ban isn’t limited to one product type. It covers raw leaf, powder, capsules, extracts, and anything else derived from the plant. There’s no wiggle room here; both compounds are named directly in the statute.

Wisconsin is one of only a small number of states that ban kratom outright. Most states allow it, and a growing number have gone further by passing Kratom Consumer Protection Act (KCPA) laws, which regulate quality and labeling rather than prohibit the substance entirely. Wisconsin hasn’t moved in that direction. No bill currently pending would legalize, decriminalize, or otherwise soften the existing ban.

Since mitragynine and 7-hydroxymitragynine are treated as Schedule I substances, kratom offenses in Wisconsin carry the same penalties as other controlled substance crimes under Chapter 961:

• First-offense possession is a misdemeanor, punishable by up to one year in county jail and fines up to $5,000.
• Repeat possession offenses can be elevated to felony charges, with correspondingly harsher sentences, including the possibility of state prison time.
• Selling or distributing kratom is a felony, carrying potential prison time and significant fines.
• Manufacturing or possessing with intent to distribute carries the steepest penalties under the statute.

These aren’t hypothetical numbers — they reflect how Wisconsin treats any Schedule I substance, and kratom is legally no different from other drugs on that list.

Given the legal status, there’s no legitimate place to purchase kratom within Wisconsin. Responsible vendors won’t ship into the state, since doing so would expose both the seller and the buyer to legal risk.

This article is for general information only and isn’t legal advice. Kratom hasn’t been approved by the FDA for any medical use. Laws change, so verify current regulations before making decisions. Anyone facing legal trouble related to kratom in Wisconsin should speak with a licensed attorney.

Wisconsin bans kratom outright, and nothing in the current legislative session suggests that’s about to change. If you’re in the state, kratom isn’t something you can legally buy, sell, or possess — and that includes having it shipped in from elsewhere. Keep an eye on the legislature if the situation matters to you; state drug laws do shift over time, just not quickly.
