What Wisconsin law says about delta-8 THC

Wisconsin defines hemp in Wis. Stat. § 94.55 as the plant Cannabis sativa L. and all its derivatives, extracts, cannabinoids and isomers with no more than 0.3% delta-9 THC on a dry weight basis, or any higher federal limit up to 1%. The same section allows people to grow, process, sell and possess hemp to the greatest extent allowed under federal law. Wisconsin’s Schedule I lists tetrahydrocannabinols, but excludes THC contained in hemp as defined in § 94.55.¹²

No Wisconsin statute names delta-8 or sets an age limit, potency cap or licence for intoxicating hemp products. One point is unsettled: the drug schedule covers THC that is chemically synthesised, and delta-8 in consumer products is usually made by converting CBD. No court ruling or official guidance resolving that question was found.²

Lawmakers tried to change the position in the 2025 to 2026 session. Bills would have redefined hemp and hemp-derived cannabinoid products, created sales rules and banned sales to people under 21, but all of them failed to pass on 23 March 2026. How the federal hemp redefinition interacts with Wisconsin’s own definition, which keeps a 0.3% delta-9 floor, has not been addressed by the state.³⁴⁵

Pending changes to watch

None in the legislature: the 2025 to 2026 hemp bills (AB 503/SB 499, AB 680/SB 644 and AB 747/SB 682) failed on 23 March 2026. New proposals could be introduced when the next legislature convenes in January 2027.

How the federal hemp change affects Wisconsin

Separate from Wisconsin law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, finished products are capped at 0.4 mg of total THC per container, and cannabinoids synthesised or manufactured outside the plant are excluded. Most delta-8 on the market is made by converting CBD, so most delta-8 products will fall outside the federal hemp definition from that date, whatever state law says.

A separate provision covering cannabinoids that the plant cannot produce naturally applies from 12 November 2026. Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail.

Timeline of recent changes

• 23 March 2026: Bills to regulate hemp-derived cannabinoid products and set a 21+ age limit (including AB 747/SB 682) failed as the session ended.
• December 2025: AB 747 and SB 682 introduced to create sales rules for hemp-derived cannabinoid products and ban sales to under-21s.

Delta-8 in neighbouring states

Rules change at the state line. Here is how delta-8 THC is treated in the states bordering Wisconsin, as of September 2026:

• Minnesota: Cannabis retailers only, 21+
• Iowa: Banned (synthetic cannabinoid)
• Illinois: Legal 21+ until 12 Nov 2026
• Michigan: Licensed marijuana stores only, 21+

Carrying products across state lines can break the law of the state you enter, and federal law also applies. Check the destination state’s rules first.

THCA in Wisconsin

THCA is treated differently: in Wisconsin it is Unclear (post-decarb hemp test) as of September 2026. Read our guide to THCA law in Wisconsin, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is delta-8 legal in Wisconsin?

Generally yes. Wisconsin’s hemp law covers hemp-derived cannabinoids and isomers with no more than 0.3% delta-9 THC, and no state law names or bans delta-8. The main open question is whether converted delta-8 counts as chemically synthesised THC under Wisconsin’s drug schedule, which no court has settled.

Is there an age limit for delta-8 in Wisconsin?

Not in state law. Several 2025 to 2026 bills would have banned sales of intoxicating hemp products to people under 21, but they all failed on 23 March 2026. Individual retailers may set their own age policies, and local rules may differ.

Is Wisconsin going to ban delta-8?

No state ban has passed. The 2025 to 2026 bills to regulate hemp-derived cannabinoid products failed in March 2026, and the next legislature convenes in January 2027. Separately, the federal hemp redefinition taking effect on 11 December 2026 is expected to remove most delta-8 products from lawful commerce nationally.
