Yes, THC gummies are legal in Wisconsin when they are hemp-derived and contain no more than 0.3% Delta-9 THC on a dry weight basis. Marijuana-derived gummies are illegal in any amount. That’s the short answer, but the practical picture is more complicated: some products sold openly sit in a legal gray area, a legal gummy can still trigger an OWI or a failed drug test, and pending legislation could pull most intoxicating gummies off Wisconsin shelves.
What Makes a Gummy Legal in Wisconsin
The dividing line is chemistry, not branding. Under Wis. Stat. § 94.55, hemp must contain no more than 0.3% Delta-9 THC on a dry weight basis, tested using post-decarboxylation or a similarly reliable method.1Wisconsin State Legislature. Wisconsin Code 94 – Section 94.55 Hemp Post-decarboxylation testing measures THC after heating, which is closer to what actually reaches you when a gummy is manufactured or digested. Wisconsin measures the limit against Delta-9 THC specifically, not a broader “total THC” figure.
Wisconsin Act 100 also provides that food is not adulterated solely because it contains industrial hemp, and people acting in compliance with the state’s hemp program receive safe harbor from prosecution under the controlled substances laws.2Wisconsin State Legislature. 2017 Wisconsin Act 1003Wisconsin State Legislature. 2017 Wisconsin Act 100 Industrial Hemp Memo That’s the legal ground legal gummies stand on.
The catch on the retail side: the Department of Agriculture, Trade and Consumer Protection does not currently require post-harvest product testing for retail hemp goods.4Wisconsin State Legislature. DATCP Hemp Program Guidance Compliance with the 0.3% limit largely relies on manufacturers policing themselves. Reputable brands publish a Certificate of Analysis (COA) for each batch, showing third-party lab results for the cannabinoid profile. If a product has no COA available, you’re trusting the label. And if a product tested by authorities exceeds the threshold, the legal exposure attaches to its chemistry, not to your intent.
Delta-8, Delta-10, HHC, and Similar Products
Delta-8 THC, Delta-10, HHC, THCP, and other isomer gummies sit on many of the same shelves as compliant Delta-9 hemp gummies. Their legal footing is not the same.
Delta-8 exists naturally in cannabis only in trace amounts. The concentrated Delta-8 in commercial products is typically produced by chemically converting CBD, a process the FDA has described as synthetic conversion.5U.S. Food and Drug Administration. 5 Things to Know about Delta-8 Tetrahydrocannabinol – Delta-8 THC The federal Farm Bill’s hemp exemption applies to material “derived from the plant Cannabis sativa L.,” and the DEA’s implementing rule states that synthetically derived tetrahydrocannabinols remain Schedule I regardless of Delta-9 concentration.6Federal Register. Implementation of the Agriculture Improvement Act of 2018
Whether converting CBD into Delta-8 counts as “synthetic” has not been definitively resolved. Wisconsin’s statutory framework tracks closely with the federal natural-versus-synthetic line.2Wisconsin State Legislature. 2017 Wisconsin Act 100 The practical result: these products are being sold openly, but they don’t share the settled legal status of compliant Delta-9 hemp gummies.
Marijuana Gummies Remain Illegal
Any gummy derived from cannabis that exceeds the 0.3% Delta-9 THC limit is a controlled substance in Wisconsin. The state has no recreational marijuana program and no comprehensive medical program. A narrow 2013 law (sometimes called Lydia’s Law) permits CBD without psychoactive effect for seizure disorders and does not authorize THC gummies of any kind.7Wisconsin State Legislature. 2013 Wisconsin Act 267
Under Wis. Stat. § 961.41, a first possession conviction is a misdemeanor carrying up to $1,000, up to six months in jail, or both.8Wisconsin State Legislature. Wisconsin Statutes 961.41 – Prohibited Acts A – Penalties A second or subsequent possession offense becomes a Class I felony, meaning up to $10,000, up to three and a half years of imprisonment, or both.9Wisconsin State Legislature. Wisconsin Statutes 939.50 – Classification of Felonies Weight-based thresholds come into play mainly when prosecutors pursue possession with intent to distribute, where amounts above 2,500 grams trigger more severe felony classifications.
A compliant hemp gummy and an illegal marijuana gummy can look and taste identical. Law enforcement can’t tell them apart on sight, so carrying products without verifiable lab documentation creates real risk during a stop or search.
Who Can Buy Them and Where
Buying a legal hemp gummy in Wisconsin does not require a medical card, a doctor’s note, or any state registry. The products are sold through private retail: CBD shops, vape stores, wellness retailers, and some gas stations and convenience stores.
Wisconsin state law does not currently set a minimum age for hemp product purchases. Most retailers voluntarily enforce a 21-and-over policy that mirrors alcohol rules, but until legislation changes, age enforcement depends on the individual store.
Driving After a Legal Hemp Gummy
This is the risk most consumers underestimate. Wisconsin enforces a zero-tolerance rule for THC and driving. Under Wis. Stat. § 346.63, you can be charged with operating under the influence if you have any detectable amount of Delta-9 THC in your blood; there is no nanogram threshold, just measurable presence.10Wisconsin State Legislature. Wisconsin Code 346 – Section 346.63 Operating Under Influence of Intoxicant or Other Drug The statute provides a narrow defense for people with a valid Delta-9 THC prescription, but retail hemp gummies are not prescription products.11Wisconsin State Legislature. Wisconsin Statutes 346.63 – Operating Under Influence of Intoxicant or Other Drug
THC from edibles is metabolized more slowly than inhaled THC. Effects last longer, and detectable THC can linger in your blood well into the next day depending on dosage and your metabolism. Someone who ate a legal hemp gummy the night before could still test positive the following morning.
A first-offense OWI with detectable THC carries a forfeiture of $250 to $275, approximately $800 in court costs and surcharges, a six-month license revocation, and a mandatory alcohol and drug assessment.12Wisconsin Court System. OWI Sentencing Guidelines Repeat offenses escalate into criminal misdemeanor and felony territory with jail time. A perfectly legal purchase can produce a criminal-adjacent penalty if you drive too soon after using it.
Drug Tests and Your Job
Standard workplace drug screens look for THC metabolites and do not distinguish between hemp-derived and marijuana-derived THC. Research from Johns Hopkins Medicine found that some participants using cannabis products near the 0.3% THC threshold triggered positive urine drug tests at the 50 ng/mL cutoff used in employment testing.13Johns Hopkins Medicine. Some CBD Products May Yield Cannabis-Positive Urine Drug Tests Regular use of legal hemp gummies raises the odds of accumulating enough metabolites to fail.
Wisconsin is an at-will employment state. No current law protects employees who test positive for THC from being fired, even when the THC came from a legal hemp product. A proposed bill (AB 812) addressed employer liability around not requiring THC testing, but it focused on shielding employers who skip testing rather than protecting employees who test positive.14Wisconsin State Legislature. Wisconsin AB812 Bill Text If your workplace tests, a legal gummy can still cost you the job.
Traveling With Hemp Gummies
Flying with hemp gummies that meet the 0.3% Delta-9 THC limit is permitted under federal policy. TSA’s official position allows products with no more than 0.3% THC on a dry weight basis, consistent with the 2018 Farm Bill; officers aren’t searching for drugs, but they will refer anything suspicious to law enforcement.15Transportation Security Administration. Medical Marijuana – What Can I Bring Carrying the product’s COA is the simplest way to answer questions if they come up.
Destination rules matter as much as departure rules. Some states have stricter positions on Delta-8 and other isomers, and landing in one of those states creates a problem that federal compliance doesn’t solve.
Federal property inside Wisconsin is its own trap. Cannabis in all forms, including edibles, is prohibited on National Forest System lands and other federally managed property regardless of state law. First-offense penalties can include a mandatory appearance before a federal magistrate, fines starting at $1,000, and up to one year of imprisonment.16U.S. Forest Service. Cannabis Use on National Forest System Lands Whether a ranger would distinguish a hemp gummy from a marijuana gummy in the field is not a gamble worth taking.
Pending Legislation Could Change the Answer
Bills introduced in late 2025 would reshape the market. Senate Bill 644 and its Assembly companion, AB 680, would create a new category called “intoxicating hemp products” and impose strict controls on their sale.17Wisconsin State Legislature. Wisconsin SB644 Bill Text18Wisconsin State Legislature. 2025 Assembly Bill 680 The bills cover Delta-8, Delta-9, Delta-10, HHC, THCP, THC-O-acetate, THCA, and any other cannabinoid producing intoxication.
Under the proposed rules, any edible hemp product containing 1.0 milligram or more of intoxicating cannabinoids per serving or per package would qualify as a restricted intoxicating hemp product. Most gummies currently sold in Wisconsin contain 5 to 25 milligrams per piece, so the threshold would cover nearly all of them.
Other provisions in the bills include:
- A firm age floor of 21 for purchase or possession
- A ban on packaging that resembles candy or is marketed to children
- Required labeling with a symbol showing the product is intended for adults 21 and older
- Escalating penalties for selling to anyone under 21, from a $500 civil forfeiture for a first violation up to $10,000 and nine months of imprisonment for three or more violations within 30 months
As of early 2026, SB 644 has been referred to the Senate Committee on Licensing, Regulatory Reform, State and Federal Affairs and has not advanced to a floor vote. Whether these specific bills pass or not, the legislative direction points toward tighter regulation of intoxicating hemp products in Wisconsin.
