Is Delta-9 Legal? A State-by-State Guide

Delta-9 THC, the primary psychoactive compound found in the cannabis plant, has been at the center of discussions regarding its classification and potential health benefits. With various states adopting their own regulations, it's become important for individuals to understand the legal status of Delta-9 THC in their specific region. 

This comprehensive guide aims to shed light on the complex legal framework surrounding Delta-9 THC by providing a detailed, state-by-state breakdown of its current status, the associated regulations, and what you need to know to navigate this intricate terrain. This guide will help you stay informed and make responsible choices within the bounds of the law.

What is Delta-9 THC?

Delta-9 tetrahydrocannabinol, often referred to as Delta-9 THC or simply THC, is one of the most well-known and studied compounds found in the cannabis plant. It is primarily responsible for the psychoactive effects commonly associated with cannabis use. 

Chemically, Delta-9 THC is a cannabinoid, a class of compounds found in cannabis that interact with the body's endocannabinoid system. It is specifically the Delta-9 isomer of THC that produces the characteristic euphoria, altered perception of time, and other effects typically associated with recreational marijuana use.

Delta-9 THC binds to cannabinoid receptors in the brain and central nervous system, leading to a cascade of physiological and psychological responses. This compound's psychoactive properties have made it a focal point of both medical research and legal regulation, as its use can have profound effects on cognitive function and behavior.

The Legal Landscape 

The legal status of Delta-9 THC in the United States is complex and varies significantly from state to state. At the federal level, Delta-9 THC remains classified as a Schedule I controlled substance under the Controlled Substances Act, meaning it is considered illegal. 

However, this legal stance has been challenged and modified in recent years, particularly with the passage of the 2018 Farm Bill. This bill legalized the cultivation and sale of hemp, a variety of cannabis that contains less than 0.3% Delta-9 THC by dry weight. As a result, hemp-derived Delta-9 THC, often known as "industrial hemp," is no longer considered a controlled substance at the federal level.

Nevertheless, the legal landscape becomes considerably more intricate when examining individual state laws. As of 2023, some states have fully legalized Delta-9 THC for recreational use, while others have legalized it exclusively for medical purposes. Some states have implemented strict regulations, permitting only limited medical use or access to hemp-derived CBD products. 

Federal Legal Status of Delta-9 THC

At the federal level in the United States, the legal status of Delta-9 THC is marked by a combination of legislation, agency policies, and ongoing debates. Delta-9 THC is classified as a Schedule I controlled substance under the Controlled Substances Act, which means it is considered illegal. 


This classification is primarily due to its psychoactive properties and potential for abuse. However, there have been significant developments in recent years that have challenged this classification.

The 2018 Farm Bill

One pivotal moment in the evolving legal status of Delta-9 THC came with the passage of the 2018 Farm Bill. This legislation brought about a major shift by distinguishing between hemp and marijuana. Hemp is a variety of cannabis that contains less than 0.3% Delta-9 THC by dry weight and does not produce the same psychoactive effects as marijuana. 

The 2018 Farm Bill effectively legalized the cultivation, production, and sale of hemp and its derivatives, including hemp-derived Delta-9 THC. This legalization at the federal level opened the door for a burgeoning industry in hemp-based products, including CBD (cannabidiol) and other cannabinoids.

DEA's Stance on Delta-9 THC

While the 2018 Farm Bill clarified the legal status of hemp and its derivatives, the Drug Enforcement Administration (DEA) retained regulatory authority over Delta-9 THC. The DEA has maintained a stance that Delta-9 THC derived from marijuana remains a Schedule I controlled substance. 

This has led to ongoing debates and legal challenges, particularly as the hemp and cannabis industries continue to grow. The DEA's position has also raised questions about the legality of Delta-9 THC products that may contain trace amounts of Delta-9 THC derived from marijuana, even if they primarily come from hemp.

The Role of the FDA

The Food and Drug Administration (FDA) plays a significant role in regulating Delta-9 THC products, particularly those marketed for medical purposes. The FDA has approved a synthetic Delta-9 THC product called Marinol for certain medical uses, such as treating nausea and vomiting associated with chemotherapy and stimulating appetite in AIDS patients. 

A State-by-state Guide

The baseline for many of these laws is the 2018 Farm Bill, a federal statute that outlines certain regulations related to hemp. However, states have taken diverse approaches to this legislation, resulting in a classification of laws into three categories: legal, restricted, and banned. Here, we break down the status of hemp Delta-9 THC in various states.

States Where Hemp Delta-9 Is Legal

Hemp-derived Delta-9 THC products enjoy legality in 42 states, along with Puerto Rico and Washington D.C. These states largely align with the Farm Bill, which dictates that Delta-9 THC in hemp must not exceed 0.3% by dry weight. While these states generally adhere to this limit, some have also introduced specific regulations addressing Delta-8 THC, which may pave the way for further legislation concerning hemp Delta-9 THC.


The list of states where hemp Delta-9 is legal includes:

  1. Alabama

  2. Alaska

  3. Arizona

  4. Arkansas

  5. Delaware

  6. Florida

  7. Georgia

  8. Hawaii

States Where Hemp Delta-9 Is Restricted

California stands as the sole state with general "restrictions" on hemp Delta-9. While a few other states have encompassed other forms of THC within the 0.3% limit established by the Farm Bill, they do not currently restrict hemp Delta-9. In California, these restrictions involve rigorous testing requirements, encompassing all forms of THC within the limit, and imposing regulations on aspects such as packaging.

States That Ban Conversions of Cannabinoids

Although not many states explicitly address hemp Delta-9 in their laws, the push to regulate Delta-8 THC has led to additional consequences in several states. Delta-8 products are typically created by chemically converting CBD into Delta-8. Some states have chosen to prohibit this conversion process, indirectly impacting Delta-9 THC as well. Our analysis has shown that nearly two-thirds of hemp Delta-9 products involve similar conversions that fall under the scope of such regulations. 

States in this category are:

  1. Colorado

  2. North Dakota

  3. Washington

States Where Delta-9 Is in Dispute but Still Legal

In some states, the legal status of hemp Delta-9 remains in dispute, often due to the introduction of bills aimed at limiting it or bills intended for Delta-8 THC that could also impact Delta-9. Vermont's situation, for instance, hinges on specific interpretations of the definition of "synthetic" cannabinoids. States in this category include:

  1. Kentucky

  2. Pennsylvania

  3. Vermont

A Deeper Dive Into Hemp Delta-9’s Legality

For our readers to dive into the vast topic of the legality of hemp-derived delta-9 THC around the US, we’ve produced this state-by-state guide.


In Alabama, hemp Delta-9 THC is entirely legal. The state has adopted the Farm Bill's definition of hemp, making hemp Delta-9 THC legal by default in the absence of contradictory laws. This clarity provides a green light for the use and distribution of hemp Delta-9 products within the state.


Alaska legalized industrial hemp with the passage of Senate Bill 6 (SB 6). This legislation not only adopted the Farm Bill's definition but also clarified that adding industrial hemp to food does not render it an "adulterated" product. It's essential to note, however, that Alaska considers other THC variants, such as delta-8, delta-10, and THC-O, as controlled substances.


Arizona's approach to hemp Delta-9 THC is in line with the Farm Bill's language, as affirmed by Senate Bill 1098 (SB 1098). The state has also restricted the sale of hemp products to individuals aged 21 or older. Nevertheless, Arizona classifies delta-8 and other THC variants, except delta-9 as explicitly exempted within the hemp definition, as Schedule I controlled substances.


Arkansas initially legalized industrial hemp in 2017, with House Bill 1640 (HB 1640) providing the most recent update. However, this legislation defines hemp without specifying Delta-9 THC, implying that most Delta-8 products would be illegal. Moreover, HB 1640 explicitly outlaws Delta-8 products, further tightening regulations within the state.


Hemp Delta-9 THC is legal in California, but Assembly Bill 45 (AB 45) has introduced significant clarifications to state laws governing hemp products. Key points established by this legislation include the allowance of adding industrial hemp to various products without constituting "adulteration." Additionally, AB 45 mandates the requirement of a Certificate of Analysis (COA) for all products sold and temporarily bans inhalable products until a tax structure can be implemented. 


Colorado initially legalized hemp, in alignment with the Farm Bill, with the passage of Senate Bill 19-220 (SB 19-220) in 2019. However, a subsequent clarification issued in May 2021 by the Department of Public Health and Environment and the Marijuana Enforcement Division rendered "chemically modifying or converting any naturally-occurring cannabinoids from industrial hemp" non-compliant with the statutory definition of an "industrial hemp product." This clarification effectively makes the majority of hemp Delta-8 and Delta-9 products technically illegal in Colorado.


Connecticut legalized industrial hemp with Senate Bill 893 (SB 893), mirroring the Farm Bill's definitions and requirements. Nevertheless, Senate Bill 1201 (SB 1201), signed into law in 2021, expanded the definition of THC to include all THC variants, such as delta-7, delta-8, and delta-10, in addition to the typical delta-9. While hemp Delta-9 remains legal, other THC products are prohibited until they can be incorporated into the state's recreational marijuana law.


Delaware's Title 3, Chapter 28 aligns with the Farm Bill's definition of hemp, thereby legalizing hemp Delta-9 products in the state. However, Delaware includes all THC variants within its Uniform Controlled Substances Act, effectively rendering delta-8 and similar products illegal.


Florida legalized hemp Delta-9 THC in 2019 with House Bill 333 (HB 333), which defines industrial hemp in accordance with the Farm Bill's guidelines.


In 2019, Georgia passed House Bill 213 (HB 213), legalizing industrial hemp in line with the Farm Bill. Without further clarification, both hemp Delta-9 and Delta-8 are entirely legal in the state.


Hawaii's House Bill 2689 (HB 2689), enacted in 2020, legalized hemp and hemp-derived compounds, adhering to the Farm Bill's framework.


Idaho most recently changed their stance on Delta-9 through House Bill 126 (HB 126) to create rules for their hemp program under the governing state body of the agricultural department.


In Illinois, the Industrial Hemp Act was signed into law in 2018, legalizing industrial hemp. This legislation mirrors the Farm Bill's suggestion of a Delta-9 THC limit, with no upper limit specified in state law. Consequently, hemp Delta-9 THC remains legal in Illinois.


Indiana law aligns with the Farm Bill's definition of hemp. As long as the Delta-9 THC concentration remains below 0.3% by dry weight, the product is deemed legal.


Iowa defines hemp in line with the Farm Bill's guidelines, making hemp Delta-9 THC legal within the state. However, it's crucial to note that delta-8 is not considered legal in Iowa due to the broad definition of tetrahydrocannabinols (THCs) outlined in the state's Controlled Substances Act.


Senate Bill 263 (SB 263) in Kansas defines industrial hemp according to the Farm Bill's specifications. Consequently, hemp Delta-9 is legal, and at the time of writing, Delta-8 and other THCs also fall within the legal framework.


Hemp Delta-9 THC is presently legal in Kentucky, with the state adopting the same definition of hemp as the Farm Bill. However, there was an attempt to ban Delta-8, along with other alternative THCs and intoxicating products made from hemp, as well as the conversion processes relied upon by Delta-8 and hemp Delta-9 companies. While this attempt was blocked, it could be reintroduced in the future. Additionally, Kentucky already considers delta-8 as legal.


House Bill 491 (HB 491) legalized industrial hemp in Louisiana, following the limitations set by the Farm Bill. Consequently, hemp-derived Delta-9 is entirely legal in the state, as long as it remains within the 0.3% THC by dry weight limit.


In Maine, Legislative Document 630 (LD 630) defines industrial hemp in line with the Farm Bill, allowing hemp-derived Delta-9 to be legal within the state.


Maryland's House Bill 698 (HB 698) aligns with the Farm Bill, effectively legalizing hemp and hemp-derived compounds in the state. Consequently, hemp Delta-9 THC is fully legal within Maryland.


In Massachusetts, House Bill 4001 (H4001) legalized industrial hemp, following the same guidelines as the Farm Bill. As a result, hemp Delta-9 THC is legal in the state.


Michigan officially legalized industrial hemp through House Bill 4744 (HB 4744), utilizing the same definitions as those found in the Farm Bill. However, it's worth noting that another bill introduced in the state essentially made Delta-8 illegal by broadening the definition of THC to encompass all THCs. Therefore, it's essential to monitor legislative developments in Michigan.


Minnesota adheres to the Industrial Hemp Development Act, which defines industrial hemp in line with the Farm Bill's provisions. Consequently, hemp Delta-9 THC is legal within the state.


Senate Bill 2725 (SB 2725) legalized hemp in Mississippi, aligning with the Farm Bill's framework. However, Mississippi did not remove THCs in hemp from its controlled substances list. Therefore, Delta-8 and other THC variants are considered illegal in the state.


Missouri's House Bill 2034 (HB 2034), enacted in 2018, legalized industrial hemp by utilizing definitions consistent with the Farm Bill. Thus, hemp Delta-9 THC enjoys full legality within the state.


Montana paved the way for industrial hemp back in 2001 with Senate Bill 261 (SB 261). Although this predates the Farm Bill, Montana incorporated the same definitions and limits. However, subsequent amendments to the Controlled Substances Act in the state have banned Delta-8, Delta-10, and other THC isomers.


In Nebraska, Legislative Bill 657 (LB 657), signed into law in 2019, legalized industrial hemp, adopting the Farm Bill's definitions and limits. As a result, hemp Delta-9 THC is legal in Nebraska.


Nevada's definition of hemp, originally from Senate Bill 305 (SB 305), imposes the 0.3% THC limit prescribed by the Farm Bill. However, this limit encompasses THC isomers, explicitly mentioning Delta-7, Delta-8, and Delta-10. Additionally, these THC variants fall under the purview of the state's Uniform Controlled Substances Act. Consequently, hemp Delta-9 is limited in Nevada, while alternatives are considered illegal.

New Hampshire

In New Hampshire, House Bill 459 (HB 459), signed into law in 2019, defines hemp in line with the Farm Bill. Thus, hemp Delta-9 THC is legal in the state, alongside variants like Delta-8 and Delta-10.

New Jersey

New Jersey legalized hemp through the Hemp Farming Act, defining it in the same manner as the Farm Bill. As a result, hemp Delta-9 THC is legal in the state, as long as it complies with the 0.3% Delta-9 THC by dry weight limit.

New Mexico

New Mexico legalized hemp in line with the Farm Bill using the Hemp Manufacturing Act. Consequently, hemp Delta-9 THC is legal in the state, adhering to the typical limit.

New York

New York's industrial hemp legislation, introduced in March 2020, follows the same definitions as the Farm Bill. This framework initially allowed for hemp Delta-9 THC by default. However, in November 2021, regulations clarified that Delta-8 is not legal in the state.

North Carolina

North Carolina's Senate Bill 352 (SB 352) removed cannabinoids in hemp from the state's Controlled Substances Act, in accordance with the Farm Bill's definition. This action effectively legalized hemp Delta-9 THC and other cannabinoids within the state.

North Dakota

North Dakota allows for the possibility of legal hemp Delta-9 THC. However, amendments to the original law explicitly include all THCs within the Farm Bill limit and also ban the conversion processes used to make Delta-8 and most delta-9 products from CBD. Consequently, while legal, it becomes more challenging to navigate in North Dakota.


Ohio's Senate Bill 57 (SB 57) legalized hemp in the state, aligning with the Farm Bill's definition. This makes hemp Delta-9 THC, along with other THC variants in hemp, legal in Ohio.


House Bill 2913 (HB 2913) legalized industrial hemp in Oklahoma, adhering to the language of the Farm Bill. As a result, hemp Delta-9, Delta-8, and other THC variants are all legal within the state.


Oregon's House Bill 3000 (HB 3000) introduced more complex rules surrounding hemp, aimed at addressing intoxicating hemp products. The legislation redefined "adult use cannabis item" to include hemp-derived cannabinoids that exceed a specific threshold, initially set at more than 0.5 mg of THCs. In essence, hemp Delta-9 is allowed but subject to regulation by the Oregon Liquor and Cannabis Commission (OLCC).


Senate Bill 335 (SB 335) legalized industrial hemp in Pennsylvania, following the limits suggested by the Farm Bill. As it stands, hemp Delta-9 THC is legal in the state. However, lawmakers intend to introduce rules to address delta-8, which could potentially impact hemp Delta-9 as well if limitations on conversions are included.

Puerto Rico

Puerto Rico's hemp program adopts the definitions and limits of the Farm Bill, making hemp Delta-9 THC entirely legal within the territory.

Rhode Island

Rhode Island defines hemp in the same manner as the Farm Bill, legalizing hemp Delta-9 THC in the state. However, other THC variants fall under the classification of controlled substances.

South Carolina

South Carolina's law utilizes the federally-defined THC limit for hemp and mirrors the Farm Bill's language. Consequently, hemp Delta-9 THC is entirely legal in the state. Nonetheless, Attorney General Alan Wilson opposes delta-8 and highlights concerns with the Farm Bill's wording.

South Dakota

House Bill 1191 (HB 1191), signed into law in 2019 in South Dakota, follows the language of the Farm Bill. This allows for the legality of hemp Delta-9 THC, Delta-8, and other variants, despite the state's generally firm stance on cannabis.


Senate Bill 357 (SB 357) legalized hemp in Tennessee, utilizing the definitions found in the Farm Bill. As a result, hemp Delta-9 THC, Delta-8, and other cannabinoids are legal in the state, provided they adhere to these definitions.


Texas' House Bill 1325 (HB 1325) defines hemp in the same manner as the Farm Bill, making hemp Delta-9 THC legal in the state, provided products meet the 0.3% Delta-9 THC limit. However, there was a notable attempt to ban Delta-8 in Texas, signaling the need to monitor potential changes in the future.


In Utah, the legalization of hemp, primarily guided by HB 58, draws heavily from the definitions laid out in the Farm Bill. Consequently, hemp Delta-9 THC enjoys legal status in the state. However, there are some notable differences in Utah's regulations. Firstly, the rules governing extracts mandate a minimum of 5% CBD by dry weight and prohibit the presence of any other psychoactive substances. Secondly, in alignment with these provisions, Delta-8 is banned under Utah's Controlled Substances Act.


Vermont incorporates Farm Bill limits into its state hemp law, ensuring that hemp Delta-9 THC is legally permitted within the state. However, the legal status of Delta-8 differs in Vermont. It is considered illegal in the state because the conversion processes required to produce high levels of Delta-8 categorize it as "synthetic." While this designation is unlikely to apply to hemp Delta-9, there remains some ambiguity in this regard.


In Virginia, HB 532 outlines the regulations governing industrial hemp, mirroring the Farm Bill's (or other federal) limits for delta-9 THC. As a result, hemp Delta-9 THC is fully legal in the state, alongside other THC variants like Delta-8.


Washington's hemp legislation, SB 5276, legalizes hemp by adopting the definitions established in the Farm Bill. However, the state imposes restrictions on conversions from CBD or hemp, explicitly mentioning conversions to Delta-9 alongside those to Delta-8. Consequently, the majority of hemp Delta-9 products are considered illegal in Washington.

West Virginia

West Virginia's HB 2694 legalized industrial hemp based on the language of the Farm Bill. This comprehensive approach ensures that hemp Delta-9, Delta-8, and other cannabinoids are entirely legal within the state.


According to Wisconsin Statute 94.55, hemp is defined in accordance with the Farm Bill. Furthermore, the state's Uniform Controlled Substances Act was updated to eliminate THCs found in hemp, including Delta-9 and Delta-8, rendering them completely legal in Wisconsin.


Wyoming's HB 171 legalized industrial hemp using language derived from the Farm Bill. As a result, hemp Delta-9, Delta-8, and other cannabinoids in hemp products are legal, provided they adhere to the 0.3% Delta-9 limit.

Washington D.C.

Washington D.C., in the absence of state-specific hemp laws, defaults to federal regulations. Therefore, it is assumed that the Farm Bill's provisions apply, making hemp Delta-9 THC, Delta-8, and other cannabinoids legal within the district.

Pending Legislation and Future Changes

The legality of Delta-9 THC is subject to change as legislation evolves. It's essential to stay updated on pending bills and potential future changes in your state's cannabis laws. Advocates and lawmakers continue to debate and propose modifications to cannabis regulations, which may impact the legal status of Delta-9 THC in various states.
