THE 2018 FARM BILL: OVERVIEW
The Agricultural Improvement Act of 2018 — commonly known as the Farm Bill — is the federal legislation that legalized hemp in the United States. Signed into law on December 20, 2018, it removed hemp from the Controlled Substances Act and established a legal framework for its cultivation, production, and sale.
The Farm Bill defines hemp as: "the plant Cannabis sativa L. and any part of that plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers" with a Delta-9 THC concentration of not more than 0.3 percent on a dry weight basis.
Key Legal Threshold: The 0.3% limit applies specifically to Delta-9 THC, not total THC, not THCa. Because THCa is a separate compound (an acid form), it is not counted toward the 0.3% Delta-9 limit in the Farm Bill's definition of hemp.
HOW THCA FLOWER FITS
THCa hemp flower complies with the Farm Bill when it contains less than 0.3% Delta-9 THC by dry weight. A hemp flower product can contain significant amounts of THCa (25-35% is common for premium indoor-grown flower) while remaining below the Delta-9 threshold. This is because THCa and Delta-9 THC are distinct chemical compounds that are measured separately in laboratory analysis.
All Texas Cannabis Direct products are independently tested by accredited third-party laboratories. Each batch comes with a Certificate of Analysis (COA) that verifies the Delta-9 THC concentration is below 0.3% by dry weight.
FEDERAL VS STATE LAW
While the Farm Bill provides federal legalization, individual states retain the authority to enact their own regulations regarding hemp-derived products. This creates a patchwork of state-level rules that retailers must navigate.
State Restrictions: Several states have enacted laws that restrict or prohibit THCa flower. Texas Cannabis Direct does not ship to states where THCa hemp flower may be restricted, including Hawaii, Idaho, Minnesota, Oregon, Rhode Island, Utah, and Vermont. This list changes as state laws evolve.
Retailers should verify the legal status of THCa hemp flower in their specific state and local jurisdiction. Even in states where THCa flower is legal at the state level, local municipalities may have additional restrictions.
RETAILER COMPLIANCE CHECKLIST
As a retailer stocking THCa hemp flower, here's what you need to maintain compliance:
- Batch-specific COAs on file: Keep a Certificate of Analysis for every product and batch in your store. These should be from accredited third-party labs and should show Delta-9 THC below 0.3%.
- Proper storage: Store THCa flower at 55-60°F, away from UV light. Improper storage can cause THCa to convert to Delta-9 THC through decarboxylation, potentially pushing the product above the legal limit.
- Age verification: Only sell to customers 21 years of age or older. Post age verification signage prominently.
- State law compliance: Verify that THCa hemp flower is legal in your state and locality. Laws change — review compliance periodically.
- Product labeling: Ensure products are properly labeled as hemp-derived and include required disclaimers.
- Supplier verification: Source from distributors who provide full documentation, batch traceability, and verified lab results.
COA DOCUMENTATION
The Certificate of Analysis is your primary compliance document. A proper COA should include:
- Lab accreditation information — ISO/IEC 17025 accredited laboratory
- Batch/sample identification — Specific to the product you received
- Cannabinoid potency panel — Including separate readings for THCa and Delta-9 THC
- Compliance determination — Pass/fail against the 0.3% Delta-9 threshold
- Contaminant testing — Pesticides, heavy metals, residual solvents, microbials
- Test date — Results should be current and specific to the batch

STAYING CURRENT
Hemp legislation continues to evolve at both federal and state levels. Proposed changes to the Farm Bill could affect how THCa is regulated in the future. Retailers should:
- Monitor state legislative changes through industry associations
- Maintain relationships with compliant suppliers who track regulatory changes
- Keep COA documentation organized and easily accessible for inspections
- Review the legal landscape periodically, especially when new legislation is proposed
