Washington, Illinois Bans Synthetic Kratom; Natural Leaf Sales Restricted to Adults 21+ Under New City Ordinance

Why it matters

Washington, Illinois has adopted a split regulatory approach that bans synthetic kratom entirely while allowing natural leaf kratom for adults 21+, mirroring an emerging policy framework being debated at state and federal levels. The model could serve as a template for other municipalities weighing prohibition versus regulation.

The big picture

Cities and counties across the U.S. are enacting a wide range of kratom policies — some banning all products, others targeting only synthetic 7-OH derivatives. The split approach, which treats natural kratom and chemically concentrated synthetic products differently, is gaining traction among policymakers who want to address synthetic 7-OH risks without eliminating access to traditional leaf kratom.

Key findings

• Washington City Board voted unanimously to amend city code banning synthetic kratom possession, sale, and use
• Natural kratom remains legal for purchase by adults 21 and older under the ordinance
• Businesses that sell natural kratom cannot permit anyone under 21 to enter the premises
• New ordinance takes effect 45 days from May 8 passage, giving retailers a compliance window
• Businesses face fines for non-compliance; police will begin with retailer outreach before enforcement
• Synthetic kratom is defined as kratom that has been chemically altered or concentrated to increase its potency

What they say

"We'll have to enforce it and we'll start with more contact with the shop owners, to tell them that this is the ordinance." — Washington Police Chief Jeff Stevens

Bottom line

Washington, Illinois adopted a split approach — banning synthetic kratom outright while preserving access to natural leaf kratom for adults — giving retailers 45 days to comply with the new ordinance.
