In July 2026 the USDA lowered the plant‑level THC limit for hemp to 0.3 % and added a per‑container cap of 0.4 mg, moving the crop toward Schedule III. Texas responded with a “Total THC Rule” that treats THCA as 88 % delta‑9 THC, tightening limits on smokable hemp flower; an appeals court denied an emergency request, allowing the rule to be enforced.

Later that month Texas reclassified delta‑8, delta‑10, THCP and related hemp‑derived cannabinoids as Schedule I controlled substances, effective July 31. Retailers must remove the products, with owners estimating inventory losses of about $100,000 and the Texas Hemp Business Council warning that the $10 billion state hemp market faces significant uncertainty. Critics say the ban could push consumers toward unregulated sources.

The ban took effect on Aug 2, imposing felony penalties of up to two years in state jail and fines up to $10,000; smoke shops in Houston report empty shelves and fear many retailers may not survive.

In Virginia, seven hemp businesses filed a federal lawsuit challenging a new law effective Aug 15 that eliminates the 25:1 CBD‑to‑THC exemption and caps hemp products at two milligrams of THC per package. Plaintiffs allege an unconstitutional taking and seek a preliminary injunction.

Separately, South Carolina affirmed that hemp‑derived Delta‑9 THC products containing no more than 0.3 % THC remain legal under the 2018 Federal Farm Bill and the state’s Hemp Farming Act, and plans to codify a minimum purchase age of 21 and require third‑party lab verification in 2026.
