The Difference Between THC and THCA

THC vs. THCA: What’s the Difference (and Why THCA Products Can Still Get You High)

Summary

Seen THCA on labels and wondered if it's just THC in disguise? You're not far off.

THC and THCA are chemically connected, but they don’t act the same until heat gets involved. While THCA itself isn’t intoxicating, most products labeled as "THCA flower" or "THCA pre-rolls" are intended to be heated, converting THCA into THC during smoking or vaping.

What Is THCA?

THCA (tetrahydrocannabinolic acid) is a raw, natural form of THC found in freshly harvested cannabis. On its own, it’s not psychoactive.

But when you apply heat, by smoking, vaping, or baking, THCA converts into Delta-9 THC, which is psychoactive. This process is called decarboxylation.

Think of THCA as the ingredient. Heat is the recipe that turns it into THC.

So, Why Are THCA Products Legal?

Under the 2018 Farm Bill, hemp-derived products are federally legal as long as they contain less than 0.3% Delta-9 THC by dry weight.

Because THCA doesn’t count toward that limit until it’s heated, many brands legally sell THCA flower, pre-rolls, and concentrates. Once you apply heat, THCA converts to Delta-9 THC, giving you all the effects of traditional cannabis.

It’s a legal loophole. And it works.

What Is THC?

THC (Delta-9-tetrahydrocannabinol) is the well-known compound that produces the classic cannabis “high.” It interacts with the body’s endocannabinoid system—especially the CB1 receptors in the brain—to produce reported effects like:

  • Euphoria
  • Altered perception
  • Relaxation or stimulation
  • Increased appetite

You’ll only feel these effects if THC is active, which is why raw cannabis (rich in THCA) doesn’t get you high until you add heat.

Why It Matters for You

If you're buying THCA products—like flower or pre-rolls—you’re essentially buying traditional cannabis in a legally compliant form. The second you light it, THCA becomes THC.

If you're using raw cannabis or cold tinctures with THCA, you won’t feel high unless you heat it.

And if you want a predictable, already-active experience, stick with edibles, beverages, or vapes made with Delta-9 THC.
