What is THCa and Why It Matters in South Dakota

THCa is the raw form of THC found in the hemp plant.

In this state it is important to note that THCa South Dakota products are non intoxicating until they are heated.

That is why you can have flower rich in THCa that still falls under the federal 2018 Farm Bill limit of 0.3% Delta 9 THC.

Farmers grow high THCa flower to meet these rules while offering strong effects. The catch is simple: once you light it, THCa changes into THC.

So is THCa legal in South Dakota at this moment The short answer Yes. THCa is legal in South Dakota only for the reason that it is not clearly banned. 

Natural THCa is not chemically modified so it is not directly covered by HB 1125.

The challenge comes when THCa is smoked or vaped because it turns into THC. That is where enforcement becomes risky.

On the federal level the 2018 Farm Bill allows hemp products if Delta 9 THC stays below 0.3%.

THCa itself is not listed as a controlled substance. But South Dakota THCa law takes a stricter approach than federal rules. 

The broad language of HB 1125 could be used against products high in THCa. Legal experts generally call it a gray area that leans toward restricted.

In July 2024, HB 1125 went into effect. This law banned hemp cannabinoids made through chemical conversion, such as Delta 8, Delta 10, and THC O.

The bill never directly named THCa, but because THCa converts into THC when heated, the broad wording creates risk.
