Illegal outside the licensed cannabis system. Delaware treats any quantity of tetrahydrocannabinols, including isomers and salts, as a Schedule I controlled substance under 16 Del. C. § 4714. The state hemp program at 3 Del. Admin. C. § 805 keys hemp to 0.3 percent delta-9 THC by dry weight and does not carve out an intoxicating-THCA category. Adult-use retail under the Delaware Marijuana Control Act opened on August 1, 2025, and that licensed channel is the only lawful route for intoxicating cannabis products.
Two parallel systems run in Delaware. The Delaware Marijuana Control Act, codified at 4 Del. C. Chapter 13, was created by HB 1 and HB 2 (152nd General Assembly). Governor Carney allowed both bills to become law without his signature on April 21, 2023, with HB 1 effective April 23, 2023 and HB 2 effective April 27, 2023. The Office of the Marijuana Commissioner administers cultivation, manufacturing, retail, and testing licenses, and adult-use retail opened on August 1, 2025 through medical conversion licensees. The Delaware Industrial Hemp Program at the Department of Agriculture operates under 3 Del. Admin. C. § 805 and was USDA-approved in January 2020. Hemp under § 805 means Cannabis sativa with delta-9 THC at or below 0.3 percent by dry weight, no broader carve-out for intoxicating THCA.
16 Del. C. § 4714 lists as Schedule I any material, compound, mixture, or preparation containing any quantity of marijuana or any tetrahydrocannabinols, their salts, isomers, or salts of isomers, that is not approved by the FDA. THCA is a tetrahydrocannabinol and decarboxylates to delta-9 THC on heating, so the state controlled-substances framework reaches it directly rather than through any total-THC test. The Division of Alcohol and Tobacco Enforcement has issued retailer guidance reinforcing that high-THC hemp products fall outside lawful retail.
Inside the Marijuana Control Act, intoxicating THC flower and concentrates are produced, tested, packaged, and sold only by Office of the Marijuana Commissioner licensees. Possession by adults 21 and older is capped at 1 ounce of leaf, 12 grams of concentrate, or 750 milligrams of THC in infused products under HB 1.
The Division of Alcohol and Tobacco Enforcement has notified retailers that hemp products exceeding the statutory THC limits or marketed as intoxicating are subject to seizure and license action. Synthetic-cannabinoid and high-THCA flower products have been priority targets since the Marijuana Control Act passed. Local police enforce possession limits above the personal-use caps.
The only lawful route to intoxicating THC products in Delaware is a licensed adult-use or medical dispensary. Adults 21 and older can purchase at adult-use retail under the HB 1 possession limits. THCA decarboxylates to delta-9 THC when smoked or vaporized and shows up on standard urine, saliva, and hair drug tests as delta-9 metabolites.
Office of the Marijuana Commissioner rulemaking continues as additional cultivator, manufacturer, retail, and testing licensees come online. HS 1 for HB 98 (2025) addresses how THC-infused beverages may be sold and remains in the legislative process. At the federal level, H.R. 5371 §781 was signed November 12, 2025 and takes effect November 12, 2026. It redefines hemp by total THC, caps finished products at 0.4 mg total THC per container, and excludes synthetic and chemically converted cannabinoids.
Is high-THCA hemp flower legal in Delaware?
No. 16 Del. C. § 4714 reaches any quantity of tetrahydrocannabinols and their isomers, and the state hemp program at § 805 does not carve out intoxicating THCA.
Can I buy THCA at a Delaware dispensary?
Yes. Licensed Office of the Marijuana Commissioner dispensaries sell intoxicating cannabis to adults 21 and older within the HB 1 possession limits.
Does THCA show up on a drug test?
Yes. THCA converts to delta-9 THC on heating and is detected as delta-9 metabolites on standard panels.
Can I ship THCA flower into Delaware?
No. Out-of-state intoxicating cannabis shipments are not authorized under the Marijuana Control Act and remain subject to 16 Del. C. § 4714.
How will federal H.R. 5371 affect Delaware?
The federal redefinition will reduce what hemp retailers nationwide can ship into Delaware after November 12, 2026, which aligns with the state framework already restricting intoxicating hemp to licensed cannabis channels.
