Oklahoma's lack of legislative clarity and regulatory definitions surrounding cannabis processing has led to compliance challenges, inconsistent labeling and enforcement difficulties within the industry.

INTRODUCTION

Oklahoma's cannabis industry has experienced unprecedented growth – and obstacles – since medical marijuana was legalized in 2018. With just over 900 active Oklahoma medical marijuana processing licenses,^[1] this evolving sector presents both opportunities and significant regulatory challenges. Unlike cultivators and dispensaries, processors operate in a uniquely complex space, necessitating clear guidelines on manufacturing, safety and compliance. However, Oklahoma's regulatory framework fails to understand and define key industry terms, leading to inconsistent enforcement, compliance confusion and industry uncertainty.

This article examines the gaps in Oklahoma’s cannabis processing laws, clarifies licensing classifications and proposes reforms to promote industry stability as well as consumer safety.

DEFINING PROCESSING AND CLASSIFYING HAZARDOUS AND NONHAZARDOUS LICENSING

The current licensing structure in Oklahoma allows for a broad definition of cannabis processors, leading to variations in compliance requirements. While some processors engage in the direct manufacturing of cannabis products – extracting, refining and infusing raw cannabis into oils, concentrates, edibles and topicals – other business models operate primarily as intermediaries. These processors act as distributors, facilitating and brokering the transfer of cannabis products from cultivators to dispensaries or other licensed businesses without engaging in the actual manufacturing process. Because their role is distinct from traditional processing, their compliance obligations differ, focusing more on inventory tracking, transportation and quality assurance rather than extraction and solvent safety protocols.

Cannabis processing refers to the transformation of raw cannabis flower into a variety of products, including oils, concentrates, edibles and topicals.^[2] The Oklahoma Medical Marijuana Authority (OMMA) defines processing as the distillation, extraction, manufacturing, preparation or production of a medical marijuana product.^[3] However, this definition lacks specificity regarding the different methods and risk factors associated with various processing techniques.

Under Oklahoma law, processing is categorized as either hazardous or nonhazardous, depending on the extraction method used.^[4] Hazardous processing uses volatile solvents, such as butane, propane, CO₂ or ethanol.^[5] These chemicals require strict safety protocols and facility buildout requirements under the Occupational Safety and Health Administration’s (OSHA) Hazard Communication Standard,^[6] including Class 1, Division 1 (C1D1) certification to prevent fire and explosion hazards pursuant to the National Fire Protection Association (NFPA).^[7]

Nonhazardous processing, by contrast, avoids volatile solvents and includes methods such as ice water hash^[8] production, rosin pressing^[9] and the manufacturing of edible products and uninfused prerolls.^[10] Additionally, processors operating under a distribution-only business model would fall under the nonhazardous category. These techniques pose fewer safety risks and are subject to less stringent regulatory oversight. 

KEY PROCESSING TERMS THAT REMAIN UNDEFINED

OMMA's regulations fail to provide clear definitions for several essential terms, creating regulatory uncertainty and enforcement inconsistencies. The absence of standardized terminology leads to misclassification of products, inconsistent testing requirements and compliance difficulties for processors. Below are some of the most critical missing definitions and their potential impacts.

Cannabis Concentrate Variations

OMMA rules define “medical marijuana concentrate” or “concentrate” as:

A substance obtained by separating cannabinoids from any part of the marijuana plant by physical or chemical means, so as to deliver a product with a cannabinoid concentration greater than the raw plant material from which it is derived. Categories of concentrate include water-based medical marijuana concentrate, food-based medical marijuana concentrate, solvent-based concentrate, and heat- or pressure-based medical marijuana concentrate as those terms are defined in the Oklahoma Medical Marijuana and Patient Protection Act.^[11]

However, OMMA regulations do not distinguish between different classifications of concentrates, with examples such as rosin,^[12] resin,^[13] distillate^[14] and hash.^[15] These variations involve distinct extraction and refinement techniques, yet they remain undefined, leading to compliance confusion, inconsistent production and discrepancies in regulatory and testing enforcement. Standardized definitions would clarify and ensure uniform application of regulations.

Concentrates should be specifically defined and classified based on their source material and processing methods. For example, cured resin is derived from dry-cured cannabis,^[16] while live resin is extracted from fresh, frozen-cured cannabis.^[17] Rosin and hash should be classified separately, as hash serves as a precursor to rosin, rather than a final extract. Establishing classifications such as these would provide regulatory clarity, improve enforcement consistency and create a standardized framework for cannabis processing compliance.

Solvent-Based vs. Solventless Extraction

The current rules lack specificity on which solvents are approved, restricted or prohibited. There is also no regulatory framework outlining acceptable residual solvent limits in final products. Without clear solvent guidelines, processors risk noncompliance due to varying interpretations of what constitutes a hazardous or nonhazardous process, potentially leading to public safety implications.

For example, the use of hexane and heptane as solvents in cannabis extraction has raised significant health and safety concerns.^[18] Hexane, a Class II solvent – per the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use^[19] – has been linked to respiratory irritation, dermatitis, liver and kidney failure and neurological disorders, such as Parkinson's disease.^[20] Heptane, while considered less toxic than hexane, is still associated with health hazards, including respiratory irritation and central nervous system effects.^[21] OSHA identified the handling and transfer of flammable solvents like hexane and heptane as potential health hazards in cannabis processing, emphasizing the need for proper safety protocols to prevent employee exposure.^[22]

Given these risks, many in the industry advocate for the use of safer alternatives, which offer effective extraction capabilities with a more favorable safety profile. A defined list of permitted solvents and standardized solvent residue thresholds would clarify compliance and enhance safety and regulatory certainty.

Terpene and Cannabinoid Profiling

Terpenes play a significant role in consumer choice and product differentiation, yet OMMA has not established a clear definition or any requirements for their reporting. Oklahoma mandates potency testing but does not require consistent terpene labeling or profile classifications.

According to Oklahoma law, "terpenoids" are defined as isoprenes that are the aromatic compounds found in cannabis, including but not limited to limonene, myrcene, pinene, linalool, eucalyptol, delta-terpinene, beta-caryophyllene, caryophyllene oxide, nerolidol and phytol.^[23] These naturally occurring hydrocarbons contribute not only to the sensory experience of cannabis but also to its therapeutic effects through a phenomenon known as the entourage effect, where they interact with cannabinoids like THC^[24] and CBD^[25] to enhance or modify their effects.^[26] However, state regulations do not currently mandate terpene-specific testing or labeling, leaving gaps in consumer transparency and standardization. As research into cannabis terpenes expands, their role in therapeutic applications, strain differentiation and product formulation continues to gain industry attention.

Cannabinoid profiling refers to the analysis of a cannabis product’s chemical composition, specifically identifying and quantifying cannabinoids such as THC, CBD and CBG.^{[27] [28]} This profiling helps differentiate between full-spectrum, broad-spectrum and isolate products. Full-spectrum extracts retain a wide range of cannabinoids and terpenes, including trace amounts of THC, promoting the entourage effect, where compounds work synergistically for enhanced therapeutic benefits.^[29] Broad-spectrum extracts also contain multiple cannabinoids and terpenes but undergo further processing to remove THC, making them a preferred choice for consumers seeking cannabis benefits without psychoactive effects.^[30] Isolates, on the other hand, contain a single purified cannabinoid, such as CBD isolate, eliminating all other plant compounds.^[31]

Defining acceptable terpene profiles and cannabinoid classification standards would improve transparency and regulatory enforcement.

Isomerization

Isomerization is a chemical process that alters the molecular structure of cannabinoids, often converting CBD into delta-8 THC^[32] or other minor cannabinoids. No clear standards exist for cannabinoids derived through isomerization, creating significant compliance challenges and uncertainty in product classification, labeling and marketing. Due to the lack of explicit regulatory guidance, processors face uncertainty regarding legality, testing requirements and permissible concentration limits, leading to inconsistencies in enforcement. This regulatory gap also complicates marketing claims as businesses struggle to determine how these cannabinoids should be labeled and whether they fall under the same compliance standards as naturally occurring THC variants. Without clear legal definitions and standardized testing protocols, the industry remains vulnerable to shifting interpretations, inconsistent enforcement and potential legal risks for processors and retailers.

Postprocessing Techniques

Techniques such as winterization (removing fats/lipids), decarboxylation (activating THC/CBD through heat) and nanoemulsification (creating water-soluble THC for edibles) are common industry practices but are not addressed in OMMA’s guidelines. The absence of regulatory oversight for these processes leaves a gap in compliance standards, potentially resulting in inconsistent product quality and safety concerns. A regulatory framework outlining acceptable postprocessing methods and safety protocols is necessary to ensure consumer and business protection.

CONVOLUTED LICENSING AND COMPLIANCE REQUIREMENTS

While licensing requirements differentiate between hazardous and nonhazardous processing, Oklahoma medical marijuana laws fail to define key aspects, such as solvent concentration limits, facility safety requirements and compliance obligations for emerging technologies. Processors must also secure permits beyond standard OMMA licensing, including Oklahoma Bureau of Narcotics and Dangerous Drugs (OBNDD) registration,^[33] Class VIII un-odorized LP Gas Administration (LPG) permit(s) for the use of propane or butane,^[34] Oklahoma Department of Agriculture, Food and Forestry (ODAFF) permits for the purchase and resale of live plants^[35] and cannabis seeds^[36] and Oklahoma State Department of Health (OSDH) food permit for edible cannabis products.^[37]

Cannabis processing facilities must comply with fire safety regulations set by the Oklahoma State Fire Marshal (OSFM),^[38] which has emphasized the need for processors to engage with local government agencies during their facility-planning phase. The fire marshal’s oversight is particularly relevant in unincorporated areas where local jurisdiction agreements may not exist, adding another layer of complexity to compliance obligations. Obtaining a business license and building permit may not suffice; additional permits and adherence to specific safety protocols are often required.^[39] Processors should be strongly encouraged to consult licensed Oklahoma design professionals for facility planning to ensure compliance with the latest state-adopted building and fire codes.

Environmental compliance also plays a critical role in cannabis processing regulations. The Oklahoma Department of Environmental Quality (DEQ) oversees key environmental permits affecting cannabis processors, including air quality, water quality and waste management.^[40] Their regulatory authority includes environmental permitting, compliance monitoring and enforcing state and federal environmental laws.^[41]

Firstly, the DEQ regulates air quality through a dual permitting system comprising construction permits and operating permits.^[42] This system applies to both major and minor sources of air pollution. Cannabis processing facilities may fall under these regulations, depending on their specific operations and emission levels. Secondly, the DEQ oversees water quality and waste management through its Water Quality and Land Protection divisions.^[43] While the general wastewater disposal permit (OKG42T) primarily addresses wastewater from medical marijuana cultivation facilities, it explicitly excludes wastewater from processing facilities.^[44] Therefore, cannabis processors are not authorized to dispose of their wastewater under this general permit. As a result, cannabis processors must seek alternative permits for wastewater disposal (if applicable to their operations) to comply with state and federal environmental regulations.^[45] For instance, discharges to waters of the state or potentially contaminated stormwater generated at processing sites require coverage under a different Oklahoma Pollutant Discharge Elimination System (OPDES) permit. Additionally, discharges to Publicly Owned Treatment Works (POTW) are not covered under this permit and may necessitate applying for coverage under a different permit.

When it comes to the disposal of solid medical marijuana waste, processors are not permitted to obtain their own DEQ-issued solid waste disposal license; instead, they must use OMMA-licensed waste disposal companies to ensure proper cannabis waste management in compliance with state regulations.^[46]

By reforming and establishing a uniform regulatory framework for cannabis processing terms, Oklahoma can create a more consistent and predictable compliance environment. This will not only protect consumer safety but also promote industry growth and regulatory adherence.

REGULATORY GAPS AND COMPLIANCE CHALLENGES

Oklahoma’s cannabis processors face numerous regulatory challenges stemming from legislative gaps, overlapping jurisdictions and financial burdens. Navigating state, federal and municipal requirements presents significant barriers to operational stability and long-term success.

While Oklahoma state law primarily regulates the distance between dispensaries and sensitive locations, municipal regulations further complicate processing compliance, as local governments impose zoning restrictions, additional permitting requirements and operational limitations. Certain municipalities have enacted local buffer zone restrictions specifically for cannabis processing facilities – for example, the city of Purcell requires a 1,000-foot buffer between processing facilities and schools; a 750-foot buffer from places of worship, libraries, museums and childcare centers; and a 200-foot distance from residential zones.^[47] Other cities may have similar restrictions, requiring processors to carefully review local zoning laws before establishing operations.

Financial constraints further hinder processors’ ability to operate properly. Due to federal prohibition, cannabis businesses have limited access to banking services, often requiring them to operate as cash-only entities.^[48] This increases security risks and complicates payroll, tax compliance and vendor payments.^[49] Additionally, IRS Code 280E prohibits cannabis businesses from deducting standard operating expenses, resulting in disproportionately high tax liabilities.^[50] Many processors face effective tax rates of up to 70%, making profitability an ongoing challenge.^[51] Without federal legalization or reclassification, businesses remain restricted from traditional financing and interstate commerce, limiting growth opportunities.

Regulatory inconsistencies exacerbate compliance difficulties. Oklahoma law does not clearly define distinctions between cannabis products and extraction methods, as noted previously, leading to discrepancies in product classification and labeling requirements. This lack of standardization results in enforcement inconsistencies, creating legal uncertainty for businesses (and attorneys) attempting to comply with shifting regulations. Further, laboratory testing inconsistencies pose a serious problem, as processors receive conflicting potency and contaminant test results from different labs, increasing the risk of mislabeling. These major discrepancies undermine regulatory enforcement and heighten the risk of unintentional noncompliance and the risk of product recall. 

LEGISLATIVE SOLUTIONS AND THE PATH FORWARD

Bridging Regulatory Gaps With Targeted Reforms and Unified Regulatory Framework

While defining key industry terms is a crucial first step in resolving regulatory ambiguities, broader reforms are necessary to create a functional and sustainable cannabis processing framework in Oklahoma. The current fragmented regulatory structure, in which multiple agencies impose overlapping and sometimes conflicting requirements on processors, presents one of the most significant challenges to industry stability.

Presently, cannabis processors are subject to regulations from multiple state and municipal agencies, each overseeing different facets of compliance, from product testing and safety standards to environmental and fire safety regulations. However, there is no centralized system ensuring uniformity in enforcement, leading to regulatory inefficiencies, delayed approvals and unnecessary financial strain on businesses. The absence of a coordinated compliance structure not only complicates regulatory adherence but also deters investment and innovation within the industry.

To address these challenges, Oklahoma lawmakers should consider the establishment of an interagency task force – a coordinated body composed of representatives from OMMA, the OBNDD, OSHA, the OSDH, the ODAFF, the OSFM, the DEQ and the LPG (and the Oklahoma Tax Commission and more), as well as industry stakeholders and legal professionals. This task force would be responsible for:

• Standardizing enforcement policies across agencies
• Clarifying jurisdictional authority to eliminate redundant or conflicting regulations
• Creating a unified compliance framework that streamlines licensing, safety and reporting requirements
• Identifying necessary updates to existing laws to reflect evolving industry practices and technology

Oklahoma must establish a single regulatory framework that aligns regulations into a streamlined and enforceable structure, reducing burdens on businesses while ensuring compliance. A unified system would eliminate contradictory regulatory interpretations and create a more predictable compliance environment. A dedicated task force would ensure that Oklahoma’s cannabis regulations evolve proactively rather than reactively, providing greater regulatory stability for businesses and consumers alike.

Defining Key Industry Terms That Remain Undefined

To create a more predictable and enforceable regulatory framework, Oklahoma must define key terms in cannabis processing to eliminate compliance ambiguity and inconsistencies. The lack of clear classifications for concentrates, solvent use and postprocessing techniques leaves processors vulnerable to regulatory uncertainty and inconsistent enforcement. Without standardized terpene labeling, solvent residue limits and cannabinoid classifications, businesses struggle to comply with shifting interpretations of the law, while consumers are left without transparency or enforcement in product labeling. Legislators and regulators must act now to establish precise definitions and uniform standards that provide clarity, promote compliance and foster a stable and sustainable cannabis industry in Oklahoma.

Financial Relief and Incentives

Beyond compliance standardization, Oklahoma lawmakers must address the financial barriers that hinder the growth and sustainability of cannabis processing businesses. The burdens of high tax rates, limited access to banking and significant compliance costs place an undue strain on processors, particularly small and mid-sized operators. To foster industry stability, policymakers should consider a range of economic incentives that ease financial pressure while encouraging regulatory adherence.

One approach is the introduction of tax incentives for compliance upgrades, allowing processors to offset the costs of facility modifications, safety improvements and new equipment necessary to meet evolving regulatory standards. Providing grants for facility enhancements –particularly for small businesses investing in energy efficiency, security measures or quality control infrastructure – would further encourage long-term compliance. Additionally, state-backed loan programs could provide processors with much-needed access to capital, helping businesses finance operational expansion, safety upgrades or technology investments that improve efficiency and compliance.

To create a more equitable tax structure, lawmakers should explore a tiered tax system that scales based on business size and revenue, ensuring that small and mid-sized processors are not disproportionately burdened compared to larger, more established operators. This would help prevent excessive tax liabilities that stifle growth and innovation, allowing smaller businesses to remain competitive in an increasingly regulated market. By implementing these financial relief measures, Oklahoma can create a cannabis processing industry that is not only compliant but also economically sustainable, promoting and sustaining jobs, investments and long-term industry viability.

Industry Collaboration and Legislative Action

While legislative changes are essential, their success hinges on coordinated efforts between regulators, industry stakeholders and legal professionals. Regulatory agencies must work closely with the industry to ensure compliance measures are both enforceable and practical. Ongoing engagement through public comment periods, industry forums and legal advisory panels can help fine-tune regulations before implementation.

The financial burden of compliance also necessitates a structured approach to enforcement. Overly aggressive penalties for minor infractions can discourage investment and drive smaller operators out of business. Regulators should focus on providing clear guidance, offering compliance assistance and implementing graduated penalty structures to ensure fair enforcement.

Additionally, attorneys and compliance specialists must stay ahead of evolving regulations to effectively advise clients. Legal professionals play a critical role in bridging the gap between business operations and regulatory requirements by interpreting new laws, advocating for fair policies and helping businesses navigate compliance challenges. Even with state-level improvements, federal uncertainty remains a barrier to growth. Advocating for federal banking reform, such as the SAFE Banking Act, would help processors access financial services, improving stability and compliance. Additionally, policymakers should push for clear recall procedures to protect processors from liability due to inconsistent testing standards.

CONCLUSION

By addressing these challenges, Oklahoma can create a regulatory framework that not only ensures compliance but also fosters business growth and innovation. Policymakers and legal professionals have a crucial role to play in shaping the future of cannabis processing regulations. Attorneys can advocate for reform by participating in legislative discussions, contributing to policy proposals and ensuring their clients remain informed of evolving compliance requirements. Proactive engagement from the legal community is essential to establishing a fair and sustainable regulatory environment for the cannabis industry in Oklahoma. Policymakers, industry leaders and legal professionals must collaborate to push for meaningful reforms that balance public safety, economic sustainability and regulatory clarity, ensuring Oklahoma remains a leader in the evolving cannabis industry.

[12] Rosin is a solventless cannabis concentrate produced by applying heat and pressure to plant material – such as dried flowers, hash or kief – to extract a resinous sap. This method preserves cannabinoids and terpenes without chemical solvents, making it a preferred option for consumers seeking a clean, full-spectrum extract.

[13] Resin is a sticky, cannabinoid-rich secretion produced by the trichomes of the cannabis plant. It serves as the raw material for many cannabis extracts and can be processed into live resin (extracted from fresh-frozen flower) or cured resin (derived from dried flower). Resin contains a high concentration of cannabinoids and terpenes, making it a key component of many concentrates. See Aitor Sainz Martinez et al., "Extraction Techniques for Bioactive Compounds of Cannabis," Nat. Prod. Rep. 2023. https://bit.ly/3XVPsWy (last visited Feb. 10, 2025).

[14] Distillate is a highly refined cannabis extract produced through distillation, a process that isolates cannabinoids by separating them from other plant compounds based on boiling points. Distillate is often odorless and flavorless, making it a versatile ingredient for edibles, vape cartridges and infused products. However, because the process removes terpenes, some products reintroduce them for enhanced effects. See Lo Friesen, supra note at 12.

[15] Hash is a traditional cannabis concentrate made by collecting and compressing trichomes, the resinous glands that contain cannabinoids and terpenes. Hash can be produced through various methods, including dry sieving, hand-rubbing or ice water extraction (bubble hash), resulting in a dense, resinous product. It is one of the oldest and most widely used cannabis concentrates. See Aitor Sainz Martinez, supra note at 13.

[16] Dry-cured cannabis refers to harvested cannabis plants that have undergone a drying and curing process to remove moisture and enhance flavor and aroma. This involves hanging the plants in a controlled environment to dry, followed by storing the dried buds in airtight containers to cure, allowing for the breakdown of chlorophyll and the development of desired flavors. See “The Ultimate Guide to Drying and Curing Cannabis for the Best Results,” Leafly, https://bit.ly/428p3Hz (last visited Feb. 10, 2025).

[17] Fresh-frozen cannabis refers to cannabis plants that are harvested and immediately frozen to preserve their cannabinoid and terpene profiles. This method skips the traditional drying and curing stages, maintaining the plant's freshness, and is often used in the production of high-quality concentrates like live resin.

[25] The Oklahoma Medical Marijuana Authority does not provide a specific definition for cannabidiol (CBD) in its regulations. However, under Oklahoma law, a "cannabinoid" is defined as "any of the chemical compounds that are active principles of marijuana," which includes CBD. See 63 Okla. Stat. §427.2(4).

[27] Cannabigerol (CBG) is a nonpsychoactive cannabinoid found in the cannabis sativa plant. It is synthesized from its precursor, cannabigerolic acid (CBGA), which also serves as a biosynthetic precursor to other cannabinoids, including cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC). CBG is typically present in low concentrations within the plant. See Benedikt B.

[32] Delta-8 THC (Δ8-tetrahydrocannabinol) is a naturally occurring minor cannabinoid in cannabis, structurally similar to delta-9 THC but with milder psychoactive effects. It is often produced synthetically through the isomerization of CBD due to its low natural concentration in cannabis plants. Delta-8 THC interacts with the CB1 receptors in the endocannabinoid system, producing euphoric and relaxing effects, though it is generally considered less potent than delta-9 THC. See ​​Daniel J.
