Cannabis has been a hot topic in recent years, especially as more states move to legalize it for medical and recreational use. But when it comes to cannabis compounds like THCa, things can get a little confusing, especially in states like Minnesota. With laws constantly shifting in the Land of 10,000 Lakes, it can feel like there are more regulations than lakes! This has residents asking themselves, “Is THCa legal in Minnesota?” The answer is simple—yet nuanced.
THCa, or Tetrahydrocannabinolic Acid, is a non-euphoric cannabinoid naturally found in raw cannabis. It’s gaining traction for its potential wellness benefits, but what really sets it apart is its ability to convert into THC when heated—making it a highly sought-after compound. But its legal status isn’t always clear. In this blog, we’ll break down everything you need to know about THCa, its connection to THC, and whether it’s legal in Minnesota. Let’s go, Minnesotans!
What Is THCa?
THCa (Also abbreviated as THCA, THC-a, and THC-A) is a naturally occurring cannabinoid in raw and live cannabis plants and the precursor to THC, the world’s most popular euphoric cannabinoid. It’s present in both marijuana and hemp plant varieties. Unlike its more famous cousin, THC (Delta 9 THC, Delta 9, D9 THC, or D9), THCa doesn’t get you buzzed. That’s because it’s non-euphoric in its raw form.
However, when you heat THCa—through smoking, vaping, or cooking—it undergoes a process called decarboxylation. This natural process converts THCa into THC, the compound responsible for the buzz associated with marijuana flower and what all enthusiasts love.
THCa is often referred to as the precursor to THC. But before it’s heated, THCa offers its own potential benefits, such as supporting relaxation and wellness, without the euphoric effects. This makes it an appealing option for those who want to explore cannabis without the euphoria.
To enjoy THCa’s non-euphoric wellness benefits, many consumers opt for THCa isolate or add THCa flower to cold foods like salads, dressings, or smoothies. However, when exposed to heat—such as when baking edibles—THCa transforms into THC, delivering a euphoric effect perfect for recreational use.
This dual nature has sparked legal debates in states like Arkansas and Georgia. But what about Minnesota? Let’s find out if THCa is legal in MN.
Is THCa Legal in Minnesota?
As of this writing, all hemp-derived THCa products are legal in Minnesota as long as they do not contain more than 0.3% THC and THCa by dry weight. Minnesota doesn’t differentiate between types of THC—including THCa. That means if you have THCa flower, the total THCa and THC content combined must stay under 0.3%. Anything above that? It’s classified as marijuana, not hemp, and falls under marijuana regulations—recreational and medical marijuana are legal in Minnesota for adults 21 and older.
Let’s explore Minnesota cannabis law more and how it affects THCa sales and purchases in the state.
Minnesota Statute 151.72 and the Reclassification of THC Products
Minnesota Statute 151.72 (Titled “Sale of Certain Cannabinoid Products”), amended in 2022, regulates the sale and distribution of hemp-derived cannabinoid products and cannabinoids. The statute was enacted to establish clear guidelines for product safety, consumer protection, and dosage limits in response to the rise of unregulated hemp-derived THC products.
Key provisions of Minnesota Statute 151.72 include:
- THC Limits. Products for consumption must not exceed 0.3% total THC, including THCA, delta-9, and other isomers, or they are classified as marijuana and subject to different regulations. Edible cannabinoid products must contain no more than 5 milligrams of THC per serving and 50 milligrams per package.
- Applies to All THC Forms. The law does not distinguish between different types of THC (e.g., THCA, Delta 8, and Delta 9) and regulates them equally.
- Hemp Definition Compliance. Products must comply with federal hemp definitions, meaning they cannot contain more than 0.3% total THC by dry weight.
- Age Restriction. Only individuals 21 and older can purchase THC products.
- Packaging and Labeling Requirements. Products must have clear labeling and child-resistant packaging. Packaging cannot be marketed toward children.
- Testing and Regulation. Manufacturers must comply with product testing and ingredient disclosure requirements to ensure consumer safety.
Minnesota’s Cannabis Laws: An Overview
Both state and federal regulations shape Minnesota’s cannabis legalization laws. Under state law, hemp products must contain no more than 0.3% “Total THC” by dry weight—we’ll get into what “Total THC” means in a second.
The 2018 Farm Bill legalized hemp plants and hemp-derived products at the federal level as long as they contain no more than 0.3% Delta 9 THC by dry weight. This means that hemp-derived THCa is technically legal under federal law, provided it meets this THC threshold. However, things get tricky when you consider that THCa can convert into THC when heated. This is where Minnesota hemp law and federal hemp law differ.
Minnesota’s “Total THC” Hemp Rule
Minnesota added a stipulation to that 0.3% rule in Statute 151.72. The legality of THCa products depends on their total THC content—including all THC derivatives such as THCa, Delta 8, Delta 10, and more. If the product’s “Total THC” levels exceed 0.3% at the point of sale, it’s considered marijuana in Minnesota, and the product falls under marijuana regulations.
So, for example, if a product contains 0.3% or less THC but includes other THC cannabinoids (like THCa) that push the “Total THC” percentage over the legal limit, it is no longer classified as hemp under state law and is subject to state marijuana laws. So, when it comes to the legality of THCa flower, it’s effectively legal as a marijuana product but illegal as a hemp product.
Minnesota legalized recreational marijuana in August 2023. This means that adults 21 and older can now possess and use cannabis flower products. While recreational marijuana is now legal in Minnesota, the state’s Office of Cannabis Management oversees the licensing and regulation of cannabis products to ensure they meet safety and compliance standards.
Can You Buy THCa in Minnesota?
Yes, you can buy THCa products in Minnesota, but you must purchase them from licensed shops that follow state guidelines. Licensed dispensaries and online platforms like Exhale Wellness are great options for finding high-quality hemp flower and other THCa products.
When shopping for THCa, always check for a Certificate of Analysis (COA). This document verifies the product’s Total THC content and ensures it meets the legal limit of 0.3% by dry weight. At Exhale Wellness, for example, we provide transparent COAs for all our products, making us a trusted source for high-quality, federally legal THCa hemp flower and other Farm Bill-compliant items.
Is THCa Specifically Legal in Minnesota?
The legal status of THCa in Minnesota is nuanced. Minnesota’s laws don’t explicitly mention THCa, but they regulate THC content in hemp and consider THCa as part of that total. This means that THCa products are legal as long as they comply with the 0.3% Total THC limit at the point of sale. However, if the total THCa and THC amount exceeds this limit, the product is classified as marijuana and subject to different regulations.
It’s also worth noting that Minnesota, especially after cannabis legalization, mirrors federal THC standards. So, any THCa product that meets the Farm Bill’s requirements is considered legal hemp. If it doesn’t, it’s considered marijuana.
Potential Legal Risks of Using THCA in Minnesota
While Minnesota law doesn’t consider THCa legal under certain conditions, there are still risks. Mislabeling is a common issue in the cannabis industry, and some products may contain more THC than advertised. This could lead to legal complications if law enforcement tests the product and finds it exceeds the legal THC limit.
Always verify lab reports and purchase from reputable retailers like Exhale Wellness to avoid these risks. Additionally, be aware that law enforcement may test for “Total THC,” not just THC by itself. Always stay informed and compliant.
FAQs About THCa Legality in Minnesota
Is THCa Legal in Minnesota Under State Laws?
Yes, THCa is legal in Minnesota as long as products containing the cannabinoid have a total THCa and THC concentration that is at or lower than 0.3% by dry weight at the time of sale. If this is the case, it is classified as hemp under state law. Any concentration above 0.3% is classified as marijuana and is subject to a different set of laws.
Does the 2018 Farm Bill Affect THCa Legality in Minnesota?
Yes, the Farm Bill legalized hemp-derived THCa at the federal level, and Minnesota follows these guidelines with some modifications. The state expanded the 0.3% THC limit to include other THC-related cannabinoids, such as Delta-8, THCa, and more. Any hemp-derived product sold legally in Minnesota must comply with these rules or be reclassified as marijuana.
How Is THCa Tested for Legal Compliance?
THCa products are tested for “Total THC,” which includes the combined THC content from THCa, other THC isomers, and any other THC in the product. This ensures the product stays within the state’s legal limit of 0.3% “Total THC” for hemp products.
Can You Buy THCa Products Legally in Minnesota?
Yes, you can buy THCa products from licensed retailers like Exhale Wellness if they comply with state and federal laws.
Is THCa Flower Legal in Minnesota?
THCa flower is legal in Minnesota as long as the total THC, THCa, and other related cannabinoid content does not exceed 0.3% by dry weight. Flower that exceeds 0.3% is treated as marijuana. Buy THCa flower in Minnesota only if it meets these expectations.
What Are the Risks of Using THCa Products in Minnesota?
The main risk is mislabeling, which could result in products exceeding the legal THC limit. This could result in potential legal issues. Always check COAs and buy from trusted sources to understand your cannabis management needs.
What Is the Difference Between THCa and Delta-9 THC?
THCa is the non-euphoric precursor to THC found in raw cannabis, which converts to Delta-9 THC when heated or decarboxylated. Delta-9 THC is the primary euphoric compound in cannabis, responsible for its iconic elevating effects.
Final Thoughts – Is THCa Legal in Minnesota? [The Groundbreaking Impact of Statute 151.72]
Is THCa legal in Minnesota 2025? The answer is yes. However, there’s more to it. Hemp-derived THCa products must have 0.3% Total THC (this number also includes the amount of THCa, THC, and other THC isomers in the product) by dry weight at the point of sale. If the concentration exceeds 0.3%, the THCa product is considered marijuana and is subject to a different set of state laws.
As Minnesota continues to evolve its cannabis regulations, staying informed is essential to safely enjoy THCa and other cannabis products. If you’re considering purchasing THCa flower, be sure to follow the rules to steer clear of any legal complications.
