Is Delta-10 THC Legal in Illinois?

Last reviewed: May 21, 2026

Yes. Delta-10 THC from federally compliant hemp is legal at hemp retail in Illinois under the Illinois Industrial Hemp Act, 505 ILCS 89/. Illinois has not enacted a statewide synthetic cannabinoid prohibition or a per-package mg cap on hemp-derived delta-10 as of May 2026. The Cannabis Regulation and Tax Act, 410 ILCS 705/, runs adult-use cannabis through licensed IDFPR dispensaries on a separate track.

Illinois cannabis and hemp overview

Illinois runs two parallel programs. The hemp program at the Illinois Department of Agriculture launched after SB 2298 was signed August 25, 2018. Adult-use cannabis launched January 1, 2020 under CRTA, signed June 25, 2019. Delta-10 is treated as hemp when the finished product meets the federal delta-9 threshold.

Delta-10 occurs only in trace amounts in the cannabis plant. Commercial delta-10 is almost always produced through chemical conversion from hemp-derived CBD, the same conversion pathway used for commercial delta-8. That production method is the focus of synthetic cannabinoid restrictions in states that have enacted them. Illinois has not. For Illinois’s approach to delta-8 see our Illinois delta-8 page.

What Illinois law actually says about delta-10

505 ILCS 89/5 defines hemp using the federal delta-9-only standard at 0.3 percent by dry weight. Delta-10 is not separately scheduled or restricted at the state level. House Bill 4293, the Pritzker-backed 2024 proposal that would have reclassified intoxicating hemp under CRTA, died at session sine die on January 7, 2025. SB 20, HB 64, and HB 5784 in the 104th General Assembly would each impose new restrictions but remain pending as of May 2026. The Illinois Attorney General has not issued a public opinion treating hemp-derived delta-10 as a controlled substance.

How enforcement has played out

IDOA enforces cultivator and processor licensing. IDPH and local health departments enforce food-safety rules on edibles. Documented enforcement actions involving delta-10 have followed the same pattern as delta-8: packaging that resembles candy or appeals to minors, sales to under-21 customers, and operators without required food-handling permits. Illinois has not pursued enforcement on the theory that hemp-derived delta-10 is a synthetic controlled substance.

What this means for retailers selling delta-10 in Illinois

• Keep finished-product certificates of analysis on file for every batch, documenting cannabinoid content and confirming delta-9 at or below 0.3 percent by dry weight. Include conversion-process documentation where available.
• Apply 21-and-over carding at point of sale. Illinois has no statewide statutory minimum for hemp, but 21+ is the industry default and matches CRTA dispensary practice.
• If operating inside Chicago, monitor City Council activity. The January 21, 2026 ordinance restricting most intoxicating hemp was vetoed by Mayor Brandon Johnson on February 13, 2026; the override failed, so Chicago retail of hemp-derived delta-10 remains unregulated for now.
• Plan now for federal H.R. 5371 §781, which takes effect November 12, 2026. The new federal definition explicitly excludes synthetic and chemically converted cannabinoids, capturing nearly all commercial delta-10.
• Pull packaging that mimics mainstream candy brands or imagery likely to appeal to minors. Packaging has driven the bulk of state and local enforcement on novel cannabinoids nationwide.
• Track IDOA and IDFPR rulemaking and pending 104th General Assembly bills. A statutory change could land mid-session.

What this means for consumers buying delta-10 in Illinois

Compliant delta-10 products are available at Illinois hemp retailers and from out-of-state online retailers shipping federally legal hemp into Illinois addresses. Delta-10 effects are commonly described as milder and more energetic than delta-8, but it still registers as delta-9 metabolites on a standard drug test. Verify the product carries a current accredited-lab COA that tested the finished product, not just upstream biomass.

Pending federal change

The biggest near-term shift is federal. H.R. 5371 §781, signed November 12, 2025, replaces the 2018 Farm Bill delta-9-only standard with a post-decarboxylation total-THC test, caps finished hemp products at 0.4 mg total THC per container, and explicitly excludes synthetic and chemically converted cannabinoids. The provision takes effect November 12, 2026. That synthetic exclusion captures nearly all commercial delta-10. Illinois has not amended 505 ILCS 89/ to align with the new federal definition.

Does delta-10 show up on a drug test?
Yes. Standard urine assays for delta-9 metabolites capture delta-10 because of structural similarity.

Can I order delta-10 online and have it shipped to Illinois?
Yes today from federally compliant retailers. The federal November 12, 2026 redefinition narrows what counts as compliant hemp.

How does Chicago handle hemp delta-10?
Chicago has no operative restriction. The January 21, 2026 ordinance was vetoed February 13, 2026 and the override failed.
