The hemp industry has never stood still, and today’s regulatory environment is changing faster than ever. As federal and state authorities refine their positions on cannabinoids, intoxicating hemp derivatives, and consumer safety standards, testing requirements are becoming more complex and less uniform.
For hemp producers and brands, this evolving landscape presents both risk and opportunity. Compliance is no longer a static checklist, it’s an ongoing strategy. At ACT LAB, one of the nation’s largest and most trusted cannabis and hemp testing laboratory networks, we help operators interpret shifting regulations, adapt their testing protocols, and protect their access to key markets.
I’ll break down what’s changing, how it impacts testing, and what hemp producers need to watch moving forward.
The Federal Framework: A Starting Point, Not a Finish Line
The modern hemp market was established under the 2018 Farm Bill, which removed hemp from the Controlled Substances Act and defined it as cannabis containing no more than 0.3% delta-9 THC on a dry weight basis. The U.S. Department of Agriculture (USDA) subsequently implemented the USDA Domestic Hemp Production Program to create federal production standards, including testing requirements for pre-harvest THC compliance.
However, the federal definition left significant gray areas, particularly around intoxicating cannabinoids derived from hemp, such as delta-8 THC and other isomers. The result: a booming market for intoxicating hemp products with little meaningful federal oversight.
At the same time, the U.S. Food and Drug Administration (FDA) has repeatedly warned that many hemp-derived cannabinoids have not been evaluated for safety and may pose risks to consumers.
Federal Action: Closing the Intoxicating Hemp Loophole
In late 2025, Congress passed a major piece of federal legislation that fundamentally alters the federal definition of hemp and effectively closes the intoxicating hemp loophole created by the 2018 Farm Bill. This change comes via the omnibus appropriations bill signed into law in November, which rewrote key language in the Agricultural Marketing Act that defines “hemp.”
What Has Changed?
Under the new law (H.R. 5371):
- The federal definition of hemp will shift from measuring only delta-9 THC to assessing total THC content, including delta-9 THC, THCA, delta-8, and other THC class cannabinoids, on a dry weight basis. Products exceeding 0.3% total THC will be categorized as marijuana under the federal Controlled Substances Act.
- Cannabinoids that cannot be naturally produced by the plant, or are synthesized or manufactured outside the plant, will be excluded from the legal definition of hemp entirely, effectively outlawing most delta-8 and similar small molecule intoxicants.
- A very low per-container THC limit (e.g., 0.4 mg total THC) will apply to hemp products intended for consumers, a threshold that renders most current intoxicating products non-compliant.
Timeline and Next Steps
The law was enacted in November 2025, and its provisions become effective on November 12, 2026. This one-year “sunrise” period is meant to give producers and regulators time to plan, but once enforcement begins, products outside the revised definition of hemp could be treated as illegal under federal drug laws.
Federal agencies are also tasked with further implementation steps in the interim, including issuing guidance on:
- Lists of naturally occurring cannabinoids,
- Cannabinoids that produce THC-like effects,
- And specifications for container measurements and labeling thresholds.
There are also efforts in Congress to extend or delay the effective date of the ban, which would provide additional time for stakeholders to organize around comprehensive regulatory frameworks rather than outright prohibition.
State-Level Divergence: A Growing Patchwork
Since the federal shift, states have responded in different ways. Some are aligning their own hemp laws with the new federal definition to avoid state-federal conflict; others are considering state-level bans on intoxicating hemp products or tightening contaminant and potency standards even further.
This divergence, combined with the federal transformation, means that hemp compliant in one state today might be non-compliant tomorrow depending on local policy.
How Regulatory Shifts Are Impacting Testing Protocols
As regulations evolve, laboratory testing requirements are expanding beyond simple potency verification. Key areas where producers are seeing change include:
Potency & Total THC Calculations
With the federal change moving to a total THC standard, labs must be prepared to quantify multiple cannabinoids with high precision. This is critical to determining legality under both state and federal definitions.
Contaminant Testing Expansion
States are increasingly requiring broad panels for pesticides, heavy metals, residual solvents, microbes, and mycotoxins. These contaminant cut-offs may vary widely, and brands selling across state lines need consistent, accredited testing support.
Finished Product Testing
Many states now require finished product testing for a range of intake forms like edibles, drinks, tinctures, and concentrates. This includes per-serving potency, homogeneity, and stability verification.
How Regulations Are Evolving in Key States in ACT LAB’s Network
As federal and state regulators respond to national policy shifts and mounting public safety concerns, several states have introduced new rules or are actively reconsidering how hemp and hemp-derived cannabinoid products are regulated. Below is a snapshot of how six influential states are handling this evolving regulatory landscape and what hemp operators need to watch.
Ohio: Tightening Controls on Intoxicating Hemp
Ohio is in the midst of significant regulatory reform. Lawmakers have advanced legislation, including Senate Bill 56 and earlier proposals like SB 86, which seeks to crack down on intoxicating hemp products and align state policy with emerging federal limits on total THC. Under these proposals:
- “Intoxicating hemp” containing levels of THC above newly proposed limits would be treated more like regulated cannabis, with sales potentially restricted to licensed dispensaries and subject to testing, labeling, and age-verification requirements.
- The state has also pursued emergency rules and executive actions aimed at banning certain intoxicating hemp products. However, these have been temporarily blocked by court orders, creating a fluid compliance environment.
For cultivators and brands in Ohio, this means closely tracking legislative developments and engaging with regulators to understand how testing requirements, particularly for total THC and minor cannabinoids, will be enforced.
Michigan: Regulated Like Cannabis in Some Contexts
Michigan has taken a more structured approach by placing hemp-derived THC products under the state’s existing marijuana regulatory system. In practice:
- Hemp-derived intoxicants such as delta-8 THC are regulated through the state’s marijuana licensing framework rather than treated as free-floating hemp products.
- This means that businesses wishing to produce, distribute, or sell such intoxicating cannabinoids often must obtain a marijuana license and comply with wholesale and retail testing, packaging, and labeling requirements analogous to recreational cannabis.
For producers, this blending of hemp and marijuana regulation underscores the importance of understanding not just hemp testing requirements but also how state cannabis regulatory bodies may treat certain products.
Pennsylvania: Largely Unregulated But Under Pressure
Pennsylvania’s hemp market has historically followed the federal framework, allowing hemp cultivation and sales of hemp-derived products that meet the 2018 Farm Bill’s 0.3% delta-9 THC limit. However:
- There have been legislative discussions and proposals aimed at banning specific intoxicating cannabinoids like delta-8 THC, reflecting growing concern about unregulated psychoactive products.
- Until further state action is taken, many intoxicating hemp products remain technically legal but largely unregulated, meaning producers should proactively engage in rigorous testing and documentation to protect market trust and prepare for possible future restrictions.
As Pennsylvania lawmakers move closer to adopting an adult-use framework in the state, producers should be prepared for potential tightening of rules around testing panels, labeling, and age-based sale restrictions.
Illinois: Active Local Actions Amid Statewide Policy
Illinois currently allows hemp-derived THC products under its Industrial Hemp Act, and many intoxicating cannabinoids remain legal within state hemp law frameworks. But:
- Local jurisdictions, most notably the City of Chicago. have adopted restrictions on the sale of certain intoxicating hemp products like delta-8 edibles and vapes.
- These local decisions reflect concern about consumer safety, marketing to minors, and the overall impact of unregulated products on public health.
This dual layer of regulation means that even if state law remains permissive, manufacturers and retailers may face municipal restrictions that influence where and how products can be sold.
Florida: Structured Product Limits and Advertising Rules
Florida has responded to regulatory uncertainties by embracing a more structured set of rules for hemp extract products. These changes include:
- Enhanced provisions for advertising, labeling, and marketing compliance were implemented in 2025, designed to align with consumer safety goals and discourage misleading claims.
- Lawmakers have also introduced legislation that would, if passed, place THC limits of 2 mg of delta-9 THC per serving and 20 mg per container, on hemp products.
For brands operating in Florida, this framework highlights the need for proactive potency testing, detailed product labeling, and marketing compliance documentation that meet the state’s evolving standards.
New York: Prohibitions and Regulatory Shifts
New York’s hemp market has been marked by prohibitions on many intoxicating hemp products, particularly delta-8 THC, and ongoing regulatory adjustments:
- The New York Cannabis Control Board has adopted emergency regulations and other measures that ban or sharply restrict the sale and distribution of intoxicating hemp products.
- Enforcement actions in late 2025 have further highlighted the state’s strict stance, including tax penalties and regulatory enforcement against retailers selling products now considered non-compliant under state rules.
Although court challenges are underway in some cases, the current trajectory in New York points to tighter control over which hemp products can be marketed and sold, and a strong emphasis on ensuring testing and labeling compliance with state-imposed standards.
What This Means for Producers
Across these states, the themes are clear:
- Increasing focus on total THC and minor cannabinoids, not just delta-9 THC alone.
- State regulatory divergence, with some states tightening rules and others maintaining current environments, while local jurisdictions enact their own bans or restrictions.
- Greater scrutiny on testing methodologies, labeling, and marketing practices to align with evolving public health priorities.
In this dynamic regulatory environment, producers operating in multiple states, or those planning to expand, must adapt their quality assurance and testing strategies to meet diverse and changing standards. Partnering with a laboratory that tracks both federal and state developments ensures that compliance isn’t just reactive, but strategic, defensible, and future-ready.
Practical Guidance for Hemp Producers
In a fluid regulatory environment, proactive compliance is essential. Here’s what hemp operators should prioritize:
- Stay Current on Federal and State Changes: With the federal definition changing and states updating their own rules, real-time compliance strategies are vital.
- Partner with Knowledgeable Labs: Work with testing partners who actively monitor regulatory shifts, like ACT LAB, to interpret requirements and test efficiently.
- Validate Analytical Methods: Ensure labs use ISO/IEC 17025-accredited methods capable of detecting low-level cannabinoids and contaminants.
- Plan for Interstate Commerce Challenges: Product compliance requirements can differ dramatically across states, and soon, at the federal level as well.
The Role of Reliable Laboratory Testing
In times of regulatory uncertainty, laboratory testing becomes more than a compliance checkbox, it’s an essential risk management tool. Accurate, defensible data protects brands from failed inspections, recalls, and market exits, while building consumer trust through transparent Certificates of Analysis (COAs).
At ACT LAB, our multi-state laboratory network provides standardized methodologies, regulatory guidance, and consultative support to help hemp producers navigate both federal and state requirements with confidence.
Looking Ahead: Agility Is the New Compliance Strategy
The hemp industry is entering a more mature regulatory phase. What began as broad federal legalization has evolved into a more nuanced and challenging framework focused on consumer safety and intoxicating cannabinoids. The brands that thrive will be those that actively monitor regulatory trends, implement adaptable testing protocols, and partner with experienced compliance-focused laboratories.
