What Is THCa? And Why It Matters in Mississippi

THCa is the raw, non-psychoactive version of THC found in hemp flower before it is heated.

Once it’s sparked, vaped, or baked, it goes through decarboxylation and transforms into the THC that gets you high.

Here’s where it gets tricky. That heat-triggered switch puts THCa in a legal gray zone, especially in states like Mississippi. With THCa law related questions popping up more than ever, it’s now one of the most watched cannabinoids in the hemp space.

Is THCa Legal in Mississippi Right Now? THCa Mississippi Law (With 2025 Update)

Mississippi follows the 2018 Farm Bill, which allows hemp products with 0.3 percent or less delta 9 THC.

That means hemp-derived THCa is technically legal under federal law. But state law paints a different picture.

Mississippi THCa Law After the 2025 Attorney General Update

In July 2025, Mississippi’s Attorney General Lynn Fitch shared a legal opinion that changed everything.

According to her statement, all consumable hemp products must be either FDA-approved or sold through the state’s medical cannabis program.

This includes flower, vapes, edibles, and oils that contain THCa.

So even if your product follows the federal hemp rules, you can’t legally sell or use it in Mississippi unless it’s part of the medical program.

That makes the THCa Mississippi law a lot more restrictive than many other states.

What Happened to HB 1502?

In 2025, lawmakers introduced House Bill 1502. It aimed to set rules for intoxicating hemp products, including how THCa flower could be tested and sold. But the bill failed to pass.

That means there’s still no clear retail path for compliant hemp THCa in Mississippi.

THCa Mississippi Federal Law vs State Law

Under federal THCa law in Mississippi, THCa flower is legal if it comes from hemp and contains 0.3% or less delta 9 THC before any heat is applied. That’s what the 2018 Farm Bill says.

But at the state level, things shift. Mississippi looks at total THC, including how much THCa could turn into THC when heated. That makes many hemp products a legal risk.

Most agencies now use the “total THC” metric, which turns THCa in Mississippi into a gray area. Enforcement is still unclear, but there’s definitely risk for sellers and buyers.

It’s always smart to double-check how your state interprets hemp law — because legality on paper doesn’t always match reality.

Can You Buy THCa in Mississippi?

Whether or not you can legally buy THCa in Mississippi comes down to who you are and how you're using it. The rules are different for medical patients and the general public.

Buying THCa in Mississippi as a Medical Patient

If you're part of the Mississippi medical cannabis program, you can access marijuana-derived THCa through licensed dispensaries. But it’s not automatic. You’ll need a valid medical card and a recommendation from a certified physician.

Once approved, you can legally buy products that contain THCa as part of your treatment.

Buying THCa in Mississippi as a General Consumer

For everyone else, the answer is not so clear. There’s no legal way to buy THCa flower in Mississippi from a local shop unless you’re a medical patient.

Some people order hemp-derived THCa from out-of-state websites. It’s shipped under federal guidelines, but the risk is still there, especially if the product gets flagged or tested.

Where to Buy THCa Flower Online in Mississippi?

Local shops in Mississippi can’t sell THCa flower unless it’s through the medical program.

But that hasn’t stopped online brands from shipping federally compliant hemp flower across state lines.
