Minnesota’s Cannabis Overhaul
Minnesota legalized recreational cannabis in August 2023, allowing adults 21+ to possess up to two ounces of marijuana and cultivate plants at home. However, this legalization created new complexity for THCA flower, which sits between hemp and marijuana in legal terms.
What Is THCA?
THCA (tetrahydrocannabinolic acid) is a naturally occurring, non-psychoactive cannabinoid found in raw hemp and cannabis plants. When heated, it converts into Δ9-THC, producing traditional cannabis effects.
Because it’s non-intoxicating until heated, THCA is federally protected under the 2018 Farm Bill when derived from hemp containing ≤ 0.3% Δ9-THC.
Minnesota’s “Total THC” Rule
Minnesota applies a total THC standard to all hemp products.
That means both Δ9-THC and THCA are counted together when determining compliance.
Under this rule:
-
Hemp products must have ≤ 0.3% total THC (Δ9 + THCA).
-
If total THC exceeds that limit, the product is legally considered marijuana, not hemp.
As a result, most THCA flower exceeds this threshold, making it illegal as hemp under state law.
Is THCA Legal in Minnesota?
Yes - but only through licensed cannabis dispensaries.
While hemp-derived THCA flower is not legal for retail sale in Minnesota due to the total THC rule, consumers can legally purchase THCA-rich cannabis flower from state-licensed marijuana dispensaries.
In short:
-
THCA hemp flower → Illegal under state hemp standards.
-
THCA cannabis (dispensary) → Legal for adults 21+.
-
Hemp-derived products with ≤ 0.3% total THC → Still legal under the 2018 Farm Bill.
Federal Protection vs. State Law
Federally, hemp-derived THCA is legal as long as Δ9-THC stays under 0.3%.
Minnesota’s inclusion of THCA in “total THC” calculations means state law is stricter than federal standards.
Consumers should only purchase from licensed or COA-verified hemp brands to ensure compliance.
Scientific Overview
According to Frontiers in Pharmacology, THCA shows potential anti-inflammatory, neuroprotective, and anti-nausea benefits.
Because it’s non-intoxicating in its raw form, it’s often used for natural wellness before activation into THC.
Final Word
THCA is not legal as hemp in Minnesota, but it’s available through licensed recreational and medical dispensaries.
Minnesota’s total THC rule classifies most THCA flower as cannabis, not hemp. Always review COAs and source from trusted, compliant producers.
