is THCA flower legal in Missouri?

Yes, THCA flower is legal in Missouri—but only if it contains no more than 0.3% Delta-9 THC by dry weight, as defined under federal hemp laws. Missouri currently does not regulate total THC, which includes THCA content.

To stay compliant, consumers must verify that THCA products come with a valid Certificate of Analysis (COA) from a third-party lab.

What Is THCA Flower?

THCA (tetrahydrocannabinolic acid) is a non-intoxicating cannabinoid found in raw hemp.

When heated, THCA converts into Delta-9 THC, the primary compound responsible for marijuana’s intoxicating effects.

Although THCA flower resembles traditional cannabis in appearance and potency, it qualifies as legal hemp if its Delta-9 THC content is 0.3% or less by dry weight.

Missouri’s Legal Status on THCA Flower in 2025

In Missouri, THCA flower is legal if it meets federal hemp standards set by the 2018 Farm Bill.

The state’s hemp law, passed in 2019 through Senate Bill 133, aligns with federal definitions and does not enforce a total THC limit on finished hemp products.

As a result, THCA flower is unregulated but legal—if tested and confirmed to contain no more than 0.3% Delta-9 THC.

However, Missouri lawmakers have introduced bills aiming to regulate intoxicating hemp products, including THCA and Delta-8. These proposals are still under review in 2025.

Why a Certificate of Analysis (COA) Is Essential

A COA (Certificate of Analysis) is a third-party lab report that verifies the cannabinoid content of your THCA flower.

To legally possess THCA in Missouri:

• You must confirm that the product contains ≤ 0.3% Delta-9 THC.
• The COA serves as your only legal proof of compliance.

Without a COA, the product could test above the legal limit and be classified as illegal marijuana under Missouri law.

Law enforcement does not accept labeling errors or lack of testing as a defense.

Can You Order THCA Flower Online in Missouri?

Under current law, Missouri follows the federal hemp standard, which means any product containing 0.3% or less Delta-9 THC by dry weight is legal to sell, ship, and possess statewide. That includes THCA flower, as long as it meets that threshold and comes with proper lab verification.

Here’s what matters: a valid Certificate of Analysis (COA). This third-party lab report confirms the product’s cannabinoid profile and ensures it’s compliant under both Missouri and federal law.

Are There Possession Limits for THCA Flower in Missouri?

No, Missouri does not set possession limits for hemp-derived THCA flower

However:

• If the product exceeds 0.3% Delta-9 THC, it is considered marijuana.
• For recreational marijuana, Missouri law allows adults 21 and over to possess up to 3 ounces of cannabis flower.

Therefore, you must ensure your THCA flower is legally classified as hemp to avoid violating possession laws.

How to Buy THCA Flower Safely in Missouri

Follow these best practices to stay legal and safe:

• Buy only from vendors who provide third-party COAs.
• Check that Delta-9 THC levels are ≤ 0.3% on the COA.

Monitor Missouri’s legislative updates, as new laws may soon regulate THCA and similar hemp derivatives.

Final Thoughts: Is THCA Flower Legal in Missouri?
