No. THCA flower and most THCA concentrates are not lawful at Virginia retail. Senate Bill 903, effective July 1, 2023, replaced the federal delta-9-only standard with a total-THC formula and added a 2 mg total-THC per-package cap (with a 25:1 CBD:THC ratio carve-out for higher-CBD products). The Fourth Circuit upheld SB 903 on January 7, 2025 in Northern Virginia Hemp and Agriculture v. Virginia. Virginia has been the most aggressive Mid-Atlantic state on hemp enforcement since the law took effect.
The Commonwealth's hemp framework runs through the Virginia Department of Agriculture and Consumer Services (VDACS), which both registers retailers and conducts on-site inspections through its Office of Hemp Enforcement. Medical cannabis operates separately under the Cannabis Control Authority and was not touched by SB 903. Adult-use cannabis possession was legalized by HB 2312 (2021) for adults 21 and over, but the General Assembly has never implemented the regulated retail market the same bill contemplated, so there are no licensed adult-use stores in Virginia in 2026.
SB 903 amended the Industrial Hemp chapter of Title 3.2 and the Food and Drink Law. Three numbers control THCA at retail:
Total THC at or below 0.3 percent dry weight, calculated as delta-9 + (0.877 × THCA). This is the post-decarboxylation calculation. Virtually all commercial THCA flower fails this test because the THCA, once converted, pushes the total well past 0.3 percent.
No more than 2 mg total THC per package, OR a CBD-to-THC ratio of at least 25:1. The 25:1 carve-out at Va. Code § 3.2-4123 (regulated hemp products) and the parallel provision at § 3.2-5145.4 (industrial hemp extracts) preserves a path for higher-THC products paired with proportionally higher CBD.
A regulated hemp product retail facility registration is required under § 3.2-4122 at $1,000 per year per location. Civil penalties run up to $10,000 per day per violation. For context on the litigation, see our piece on legal challenges to hemp definitions.
VDACS conducted 424 inspections in the first 12 months after SB 903 took effect and cited 346 businesses for 17,715 individual violations (FY 2023-24). Enforcement focused on THCA flower, prerolls, vapes, and edibles that exceeded the 2 mg per-package cap or failed the total-THC calculation. The Office of Hemp Enforcement expanded into inhalable hemp inspections in September 2025, layered on top of the existing edible inspection program.
The federal preemption challenge came and went. The Fourth Circuit affirmed the district court on January 7, 2025 in Northern Virginia Hemp and Agriculture, LLC v. Commonwealth of Virginia, No. 23-2192. The panel held that the 2018 Farm Bill does not preempt state total-THC standards, that the dormant Commerce Clause challenge failed because the cap applies identically to in-state and out-of-state operators, and that the plaintiffs lacked standing to challenge the sales restriction because they had not pleaded facts showing they were licensed processors. That ruling is the leading federal circuit decision on Farm Bill hemp preemption.
You will not find THCA flower or most THCA concentrates at a Virginia retailer. Compliant edibles, tinctures, and beverages that pass the 2 mg per-package cap or the 25:1 ratio remain on shelves. Out-of-state online sellers still ship federally compliant hemp into the state, but those products are not lawful at Virginia retail and VDACS has authority to act on shipments that fail the state standard. THCA shows up on every standard drug test once heated, because heat converts it to delta-9 THC.
No pending bill in the 2026 Virginia General Assembly would loosen SB 903. The Fourth Circuit ruling closed the federal preemption argument for the foreseeable future. The active federal item is H.R. 5371 § 781, which takes effect November 12, 2026 and caps finished hemp products at 0.4 mg total THC per container while excluding synthetic and chemically converted cannabinoids from the federal hemp definition. That cap is tighter than Virginia's on a per-container basis and will further narrow what Virginia retailers can carry.
Is THCA flower legal in Virginia in 2026?
No. The combination of the total-THC formula and the 2 mg per-package cap makes essentially all commercial THCA flower unlawful at retail.
Did the Fourth Circuit really uphold SB 903?
Yes. The Fourth Circuit affirmed on January 7, 2025 in Northern Virginia Hemp and Agriculture v. Virginia, No. 23-2192. The court rejected Farm Bill preemption, rejected the dormant Commerce Clause challenge, and held the plaintiffs lacked standing on the sales restriction claim.
What is the 25:1 CBD:THC ratio carve-out?
SB 903 lets a product exceed the 2 mg per-package THC cap if it contains CBD in a ratio of at least 25 parts CBD to 1 part THC. The carve-out preserves higher-THC products paired with proportionally higher CBD.
How much does the Virginia retail hemp registration cost?
$1,000 per year per facility under Va. Code § 3.2-4122.
Does THCA show up on a drug test?
Yes. Once heated, THCA converts to delta-9 THC and produces the same metabolites measured by standard urine, saliva, and hair screens.
What are the penalties for a Virginia retailer selling non-compliant THCA products?
Civil penalties up to $10,000 per day per violation under the Food and Drink Law, plus product seizure, registration suspension, and registration revocation.
