The Future of Hemp: Understanding Federal THC Policy and Texas' Regulatory Approach

The hemp industry exists because of a single sentence buried in a massive piece of federal legislation: the 2018 Farm Bill's redefinition of "hemp" as cannabis containing no more than 0.3% delta-9 THC by dry weight. That sentence created a multibillion-dollar industry almost overnight. It also created a persistent tension that federal regulators, state legislatures, and the hemp industry are still fighting over today — most visibly through the debate over how THC should actually be measured. This article walks through where hemp policy stands now, why the "total THC" measurement debate matters so much, and what different possible futures could look like for consumers.

The 2018 Farm Bill: What It Actually Created

Before 2018, hemp and marijuana were legally indistinguishable — both were classified as Schedule I controlled substances under federal law, regardless of their chemical makeup. The Agriculture Improvement Act of 2018 (commonly called the Farm Bill) changed that by defining "hemp" as any part of the cannabis plant with a delta-9 THC concentration of no more than 0.3% by dry weight, and removing that definition from the Controlled Substances Act entirely. Anything above that threshold remained legally "marijuana."

That single distinction — based purely on a chemical threshold, not plant species — opened the door to a legal hemp industry covering fiber, grain, CBD extracts, and eventually an entire category of hemp-derived cannabinoid products including THCA flower, delta-8 products, and hemp-derived beverages. Industry estimates have placed the U.S. hemp-derived cannabinoid market in the billions of dollars annually, with THCA flower and related products becoming one of the fastest-growing segments as consumer awareness has grown.

USDA's Role vs. State Regulation

The Farm Bill gave the U.S. Department of Agriculture authority over hemp cultivation — licensing farmers, setting sampling and testing protocols for crops in the field, and approving state hemp plans. What the Farm Bill did not do is create a federal framework for regulating consumable hemp products sold at retail — things like flower, edibles, and beverages. That gap has been filled unevenly, state by state, which is exactly why hemp law looks so different depending on where you live. Texas regulates consumable hemp through DSHS under HB 1325; other states have built entirely different licensing and testing systems, and a few have banned intoxicating hemp products outright.

The Central Debate: "Total THC" vs. Delta-9 THC Measurement

This is the single most consequential unresolved question in hemp policy today. The Farm Bill's 0.3% threshold is written in terms of delta-9 THC specifically. But hemp plants also naturally contain THCA — a non-intoxicating precursor that converts into delta-9 THC when heated. Under a strict delta-9-only testing standard, a raw flower sample can contain very little delta-9 THC and still be legally compliant, even if it contains substantial THCA that would convert into well above 0.3% THC once smoked or vaped.

A "total THC" testing standard closes that gap by mathematically combining THCA and delta-9 THC into a single potency number before checking compliance (using a standard conversion formula that accounts for the fact that decarboxylation is not 100% efficient by weight). Under total THC testing, many current high-potency THCA flower products would not pass, because their combined cannabinoid content would exceed 0.3%.

Federal agencies, including the DEA and USDA, have at various points signaled support for a total THC approach in the cultivation and testing context, while the retail consumable-hemp side of the industry has largely operated under delta-9-only interpretations. That mismatch is at the heart of nearly every state-level hemp fight happening right now, Texas included.

What a Total THC Standard Would Mean for THCA Products

If total THC becomes the federal or state standard for consumable hemp compliance, the impact would fall hardest on smokable flower and concentrate products, since these are the categories where naturally high THCA content is both common and desirable to consumers. Realistically, three things could happen:

• Reformulation — cultivators shift toward hemp varietals bred for lower overall cannabinoid potency, or processors adjust extraction methods, to stay under a total THC threshold.
• Category consolidation — some higher-potency products migrate toward states with adult-use cannabis programs that can legally accommodate them, while hemp retail in stricter states shifts toward lower-potency formats.
• Grandfather or grace periods — as seen in other regulatory transitions, states and potentially federal rulemakers typically build in compliance windows rather than an instant cutoff, giving the industry time to adapt.

None of these outcomes is happening tomorrow. But understanding the mechanics helps explain why so much of the industry's lobbying energy is focused on this one technical measurement question rather than on legality in the abstract.

Industry Response and Lobbying

Hemp industry trade groups — including national organizations representing growers, processors, and retailers — have been active participants in both federal Farm Bill negotiations and state-level rulemaking, generally arguing for testing and labeling standards that preserve the existing product category while addressing legitimate concerns about youth access and product safety. On the other side, some public health organizations and law enforcement groups have pushed for tighter total THC standards, arguing the current delta-9-only framework functions as an unintended loophole rather than a policy choice. Both sides have been vocal in public comment periods on state proposals like the one currently under review at Texas DSHS.

These lobbying efforts play out on two parallel tracks. At the federal level, hemp trade associations engage directly with USDA and congressional agriculture committees during Farm Bill negotiations, pushing to keep the delta-9-only definition intact or to secure long compliance windows if a total THC standard is ever adopted nationally. At the state level, the same conversations happen in miniature during agency rulemaking processes like the one at Texas DSHS, where local retailers, cultivators, and testing labs submit public comments directly rather than working through national lobbying channels. Because state rulemaking timelines move faster than federal Farm Bill cycles, most of the concrete regulatory change hemp businesses have had to adapt to in recent years has come from the state track rather than the federal one.

Why State Regulation Has Diverged So Sharply

Because the Farm Bill left consumable hemp product regulation to the states, each state legislature and health agency has effectively built its own hemp policy from scratch, shaped by local politics, existing cannabis policy (or lack thereof), and lobbying pressure. States with established medical or adult-use cannabis programs have often folded intoxicating hemp products into those existing frameworks or restricted them, since they already have licensing infrastructure built for cannabis. States without existing cannabis programs, like Texas, have had to build hemp-specific regulatory systems largely from scratch, which partly explains why the process has been slower and more contentious.

How Hemp Retailers Navigate an Uncertain Regulatory Timeline

For a retailer, operating in this environment means building sourcing and testing relationships flexible enough to absorb a rule change without disrupting customers. That typically means working with more than one cultivator and more than one testing lab, so that a shift in potency standards or testing methodology in one relationship does not leave the business without compliant inventory. It also means treating labeling and packaging as something to be updated proactively rather than only when legally required — a retailer that already discloses full cannabinoid panels and batch-level COAs has far less to change if a stricter labeling rule is adopted than one that has only ever met the bare legal minimum.

What the Next Farm Bill Renewal Could Mean

Farm Bills are typically reauthorized every five years, and hemp policy is one of the provisions up for renegotiation each cycle. A renewed Farm Bill could leave the current delta-9 definition untouched, formally adopt a total THC standard nationwide, add new consumer safety provisions (like federal labeling or age-verification requirements), or — less likely but possible — attempt to more narrowly redefine hemp in ways that shrink the legal product category. Because Farm Bill negotiations involve agriculture interests far beyond cannabis (crop insurance, nutrition programs, conservation funding), hemp policy is often a relatively small piece of a much larger legislative negotiation, which has historically made it slow to change but also subject to being bundled with unrelated priorities.

International Hemp Market Comparison

The U.S. is not alone in wrestling with these definitions. Canada regulates hemp-derived cannabinoids under its broader federal cannabis framework, since cannabis is legal for adult use nationally, avoiding the "loophole" dynamic entirely. The European Union has generally taken a more restrictive approach to THC content in hemp products, with several member states enforcing stricter total THC limits than the U.S. federal standard. This global patchwork illustrates that there is no single "correct" regulatory model — it is a policy choice each jurisdiction makes based on its own priorities around public health, agriculture, and criminal justice.

The Economic Stakes for Farmers and Rural Communities

It is easy to talk about hemp policy purely in terms of THC thresholds and testing methodology, but the underlying economics affect real farming communities. Hemp is an agricultural row crop, and farmers who plant it make multi-month commitments — seed costs, land use, labor, and processing contracts — based on the regulatory environment they expect at harvest time. Sudden regulatory shifts create real financial risk for growers who cannot simply switch crops mid-season if a state changes its testing standard after planting. This is part of why industry groups have pushed hard for predictable, phased-in compliance timelines rather than abrupt rule changes: a grower who planted a high-THCA cultivar under one set of rules should not be left holding an unsellable crop because the rules changed six months later.

Rural economies in hemp-producing states have also come to rely on the processing and retail side of the supply chain — drying and curing facilities, extraction labs, packaging operations, and retail storefronts all create jobs that did not exist before the 2018 Farm Bill. Policymakers weighing stricter hemp regulation are increasingly aware that overly aggressive restrictions do not just affect consumers; they ripple back through an entire regional supply chain that has grown up around the current legal framework.

What Consumer Protection Advocates Are Pushing For

Not every voice in this debate is focused on restricting the market — a significant share of the policy conversation is about improving product safety within whatever framework ultimately governs hemp. Common asks from consumer advocacy groups include mandatory third-party testing disclosure (rather than self-reported potency claims), standardized serving sizes for edibles and beverages, child-resistant packaging as a baseline requirement rather than a best practice, and clearer, more prominent labeling of cannabinoid content and potential effects. Many of these priorities overlap significantly with what responsible retailers already do voluntarily — Ember Trees, for example, publishes COAs for our products regardless of what any specific state currently mandates, because it is simply good practice for a consumable product category.

Consumer Impact Scenarios

It is useful to think through a few realistic scenarios rather than assuming any single outcome:

• Optimistic scenario: States adopt clear, consistent testing and labeling standards (whether delta-9-only or total THC) with reasonable compliance timelines, giving consumers predictable access to tested, labeled products and giving retailers regulatory certainty.
• Neutral scenario: The current patchwork continues — some states tighten rules, others do not, and consumers in stricter states see product formulations shift over time while the broader hemp industry keeps operating nationally.
• Pessimistic scenario: Aggressive federal or state restrictions significantly shrink the legal hemp-derived cannabinoid product category, pushing more consumers toward state-licensed cannabis markets (where legal) or unregulated gray-market sources (which is worse for consumer safety, not better).

Notably, even in the pessimistic scenario, the direction of travel across nearly every state that has gone through this process has been toward more regulation, not prohibition — Texas's own 2025 veto of an outright ban in favor of agency rulemaking is a clear example of that pattern.

The Role of Testing Labs in the Total THC Debate

Third-party testing labs sit at the center of nearly every hemp policy question, since they are the ones who actually generate the numbers regulators and retailers rely on. Different labs have historically used slightly different methodologies, equipment calibration, and sampling protocols, which has occasionally produced inconsistent results for the same product tested at different facilities — a problem regulators are increasingly trying to solve through standardized testing protocols rather than leaving methodology up to individual labs. As total THC calculation methods get formalized in state rules, testing labs will need updated accreditation and standardized conversion formulas to ensure a product deemed compliant in one lab would be deemed compliant industry-wide. This is a less visible but genuinely important part of the regulatory infrastructure that has to mature alongside any new potency standard.

What Ember Trees Does to Stay Ahead of Regulatory Change

We built our compliance process assuming change is the constant, not the exception. That means working with testing labs capable of running both delta-9-only and total THC panels, maintaining direct relationships with compliant cultivators who can adjust sourcing if potency standards shift, and tracking rulemaking at both the federal and Texas state level continuously rather than reactively. Every product on our menu ships with lab-verified compliance today, and our sourcing decisions already account for the direction regulation appears to be heading — not just where it currently stands.

Frequently Asked Questions

Will hemp become more restricted nationally?

The clearest trend across states is toward more testing, labeling, and licensing requirements rather than outright bans, though the degree of restriction varies significantly by state. A nationally standardized total THC rule remains possible but has not been adopted federally as of today.

What does the next Farm Bill renewal mean for hemp?

It is one of the few realistic paths toward a unified national standard for hemp-derived THC products, but Farm Bill negotiations move slowly and involve many priorities beyond cannabis, so significant changes are unlikely to happen quickly or without substantial industry input.

Is THCA safe from a regulatory perspective long-term?

THCA itself is a naturally occurring, non-intoxicating cannabinoid and is not the target of regulation — what is being debated is how THCA is counted toward total THC potency limits for finished products. Long-term, expect testing and labeling standards to keep evolving, with compliant retailers adjusting sourcing and formulation as needed.

Why does the delta-9-only vs. total THC debate matter so much?

Because it is the single biggest lever regulators have to determine which hemp products remain legally sellable. A total THC standard would meaningfully shrink the category of legal high-potency smokable flower, while a delta-9-only standard preserves it.

Could hemp products become federally illegal again?

That would require Congress to remove or substantially rewrite the Farm Bill's hemp definition, which is not currently under serious legislative consideration. Far more likely are state-by-state and testing-methodology adjustments rather than a full federal reversal.

How can I keep up with changes that might affect the products I buy?

Buy from retailers who are transparent about lab testing and actively monitor regulatory developments — like Ember Trees — and check in periodically on our blog for policy updates as they develop.
