Is THCA Flower Legal in Minnesota? 

State law doesn’t consider THCA flower legal hemp. 

Under current law, THCA hemp flower is cannabis in Minnesota. This is because state law requires THCA to be calculated towards the total delta 9 THC content in hemp products. 

The “acceptable hemp THC level” in a hemp product must not exceed 0.3%, with THC including both delta 9 THC and THCA. 

The high levels of THCA in this type of flower make it illegal under state law because Minnesota has a total THC standard (THCA + delta 9 THC) for hemp products. 

This makes the legal status of THCA flower in Minnesota complex as the state recently legalized marijuana. Due to its resemblance to regular cannabis flower, THCA flower is legal to purchase in this state. 

If marketed and sold as hemp, THCA flower is illegal in Minnesota. However, you can purchase it from a licensed marijuana dispensary because it practically falls under cannabis regulations. 

While you can’t purchase THCA hemp flower in Minnesota as hemp, you can buy regular cannabis flower. In August 2023, Minnesota legalized the sale, use, and possession of cannabis for recreational purposes. If you’re 21 and older, you can possess up to 2 ounces of weed within state borders.

What is THCA Flower? 

THCA flower is hemp flower that’s in line with the 2018 Farm Bill but has an almost identical cannabinoid profile to marijuana flower. 

Tetrahydrocannabinolic acid, or THCA, is the main compound in this type of flower, which transforms to delta 9 THC when heated. THCA flower will get you intoxicated just as much as regular cannabis flower. 

Is THCA Legal Federally? 

Hemp-derived THCA is legal under the 2018 Farm Bill. 

According to expert cannabis lawyer Rod Kight, finished hemp products like THCA flower, are legal if their delta 9 THC levels don’t exceed 0.3% by dry weight. Kight states that the concentration of delta 9 THC in the product is the only metric that counts in finished hemp products. This means that the concentration of THCA in the product is not calculated under federal law. 

The only time the THCA levels are taken into account is in pre-harvested hemp, not finished products. So, if the product contains less than 0.3% delta 9 THC — regardless of its THCA levels — it’s legal hemp federally. 

Is THCA a Controlled Substance in Minnesota?

Hemp-derived THCA in a concentration of no more than 0.3% is not a controlled substance in Minnesota. 

The levels of THCA in marketable hemp products must not exceed 0.3% by dry weight. This is because state law includes THCA in the definition of THC. 

Minnesota legalized marijuana for recreational use in 2023, so THCA flower is legal if sold as weed in licensed marijuana dispensaries. If you’re 21 and older, you can buy cannabis flower from a licensed dispensary. 

Can I Order THCA Flower Online in Minnesota? 

Yes, you can order THCA flower in Minnesota online, but from licensed marijuana dispensaries.

Under state law, hemp products with high THCA levels (above 0.3%) can be sold as marijuana products in licensed dispensaries. State law considers hemp products lawful if their total THC concentration (THC + THCA) doesn’t exceed 0.3% by dry weight.
