THC vs. THCA: What’s the Real Difference? (And Why It Barely Matters)


THC vs THCA

If you’ve been browsing cannabis products online, you’ve probably seen THCA and THC used interchangeably—but are they really different? Here’s the truth: THCA and THC are practically the same thing, and understanding the subtle difference between them can unlock powerful (and legal) benefits—especially when you shop at THCA by Mail.

In this blog, we break down THCA vs. THC, show why they produce the same effects after heating, and explain why THCA is a legal, shippable alternative to Delta-9 THC. Plus, we’ll show you how to get the strongest THCA flower, pre-rolls, and diamonds delivered straight to your door from our online store.


What Is the Difference Between THC vs THCA?

  • THCA (Tetrahydrocannabinolic Acid) is the raw, non-psychoactive cannabinoid found in fresh cannabis.

  • THC (Delta-9-Tetrahydrocannabinol) is the psychoactive version that gives you that familiar cannabis high.

Here’s the catch: when THCA is heated—via smoking, vaping, or cooking—it converts into THC. This process is called decarboxylation. So if you’re lighting up THCA flower, you’re actually activating the THC and getting the same effects as traditional cannabis.


👉 Bottom line: THCA becomes THC when heated. That means THCA flower = THC flower in effect.


Is THCA Legal? THC and THCA?

Yes—under the 2018 Farm Bill, THCA is federally legal as long as it's hemp-derived and contains less than 0.3% Delta-9 THC by dry weight. That means you can legally order high-potency cannabis products online that look, smell, and feel exactly like THC—but are shipped as hemp.

That’s exactly what we do at THCA by Mail.

We ship premium, lab-tested THCA flower and concentrates across the U.S., so you can enjoy real cannabis without the legal risk.
