No. Delta-10 THC is illegal at non-dispensary retail in Maryland. The Appellate Court of Maryland held on September 9, 2025 in Governor Wes Moore, et al. v. Maryland Hemp Coalition, et al. that intoxicating hemp products including delta-10 are now and have always been illegal outside the Maryland Cannabis Administration (MCA) licensed dispensary system. Delta-10 is named in the appellate opinion alongside delta-8 as a product the Cannabis Reform Act restricts to the licensed channel.
Maryland voters legalized adult-use cannabis through Question 4 in November 2022. The General Assembly passed the Cannabis Reform Act (HB 556 / SB 516), signed by Governor Wes Moore on May 3, 2023 as Chapters 254 and 255, effective July 1, 2023. The Act sits in the Alcoholic Beverages article at Md. Code Ann., Alc. Bev. Title 36. The Maryland Cannabis Administration regulates the licensed market. The Alcohol, Tobacco, and Cannabis Commission (ATCC), housed under the Comptroller, handles field enforcement against unlicensed THC sales.
The Cannabis Reform Act treats a hemp product as an intoxicating cannabis product when it exceeds 0.5 mg of THC per serving or 2.5 mg per package, and routes those products to MCA-licensed dispensaries. The tincture carve-out at 100 mg per bottle and a 15:1 or greater CBD:THC ratio is the only general non-dispensary lane for products with measurable THC. Delta-10 is an isomer of delta-9 THC produced almost exclusively through chemical conversion from hemp-derived CBD, which puts it inside the intoxicating cannabis category and inside the synthetic-cannabinoid framework that drew the heaviest enforcement focus from the General Assembly. The September 9, 2025 appellate opinion at Moore, No. 1590, Sept. Term 2023, identifies delta-10 by name as illegal outside the dispensary channel. For comparison with the parallel framework on delta-8, see our Maryland delta-8 page.
A Washington County preliminary injunction from October 2023 had limited ATCC enforcement against pre-July 2023 hemp retailers. The Appellate Court lifted that injunction on September 9, 2025. SB 214 and HB 12 (2025, Chapters 58 and 57), effective July 1, 2025, gave ATCC field officers citation authority and removed the need for chemical testing before enforcement. Packaging or labeling violations alone now support seizure. ATCC reported 111 intoxicating-THC enforcement cases between July 1, 2025 and the end of 2025. Fines under the Alcoholic Beverages article reach $5,000 per offense and $10,000 for synthetic THC violations, the higher tier that typically applies to delta-10.
Delta-10 is no longer legal at hemp retail in Maryland. Adults 21 and over can purchase cannabis products at an MCA-licensed dispensary. Compliant CBD products that meet the per-serving cap or the tincture carve-out remain available at hemp retail. Delta-10 produces effects similar to delta-9 THC, and standard urine, saliva, and hair drug tests typically register a positive because the metabolites overlap.
Federal H.R. 5371 §781, signed November 12, 2025 and effective November 12, 2026, redefines hemp using a post-decarboxylation total-THC test, caps finished hemp products at 0.4 mg total THC per container, and excludes synthetic and chemically converted cannabinoids. Delta-10 is produced through hydrogenation or isomerization of hemp-derived CBD or delta-9, which puts it inside the excluded category. For background see our 2018 Farm Bill revision explainer.
Is delta-10 legal in Maryland in 2026?
No. After the September 9, 2025 Moore appellate ruling, intoxicating hemp including delta-10 is illegal at non-dispensary retail.
What is delta-10 and how is it different from delta-9?
Delta-10 is an isomer of delta-9 THC. It is produced almost exclusively through chemical conversion from hemp-derived CBD or delta-9. The conversion process is what places it inside the synthetic-cannabinoid framework that Maryland and the new federal definition target.
Does delta-10 show up on a drug test?
Yes. Delta-10 metabolites overlap with delta-9 metabolites on standard tests. Specialty panels that distinguish them are uncommon.
What changed on September 9, 2025?
The Appellate Court of Maryland reversed the Washington County injunction in Moore v. Maryland Hemp Coalition, No. 1590, Sept. Term 2023. The court named delta-8 and delta-10 specifically as products that are now and have always been illegal outside the MCA dispensary system.
Can I order delta-10 online to a Maryland address?
The Cannabis Reform Act applies regardless of shipping origin. ATCC enforcement reaches mail-order sales delivered into Maryland.
What changes November 12, 2026?
Federal H.R. 5371 §781 takes effect and excludes synthetic and chemically converted cannabinoids from the federal hemp definition. Delta-10 loses federal Farm Bill protection on that date.
