How THCA Is Made: A Simple Breakdown

If you’re looking into THCA products and wondering how this cannabinoid is made, you’re not alone. At Tosi, we’re all about helping you understand what goes into our products—so here’s a simple, straightforward guide to how THCA comes to life in the cannabis plant.

What Is THCA?

THCA stands for tetrahydrocannabinolic acid. It’s a natural compound found in raw, unheated cannabis. Think of it as THC’s raw form. Unlike THC, THCA doesn’t get you high—at least not until it’s heated.

That makes THCA an ideal option for people who want the benefits of cannabis without the psychoactive effects (unless they choose to activate it).

Where Does THCA Come From?

It all starts inside the cannabis plant—specifically in tiny, crystal-like parts of the plant called trichomes. These are found mostly on the flower buds.

Here’s a quick overview of how THCA is made:

  1. The plant first produces CBGA (cannabigerolic acid). It’s sometimes called the "mother of all cannabinoids."

  2. Then, an enzyme called THCA synthase converts CBGA into THCA.

  3. Trichomes hold the THCA—along with terpenes and other cannabinoids.

So in short, THCA is created by the plant naturally as it grows.

How Growers Increase THCA Content

At Tosi, we source flower from cultivators who specialize in high-THCA genetics. Here’s how it’s done:

  • Strain selection: Some strains produce more THCA than others.

  • Harvest timing: Picking at the right time is key.

  • Proper drying and curing: This keeps THCA from turning into THC too early.

Some manufacturers add THCA isolate to flower, but we prefer a natural, full-spectrum product that stays true to the plant.

When Does THCA Become THC?

Here’s the important part: THCA doesn’t turn into THC until it’s heated. This process is called decarboxylation. When you smoke, vape, or cook with cannabis, that heat removes a carboxyl group from the THCA molecule, turning it into Delta-9 THC—the compound that causes the high.

So if you’re just holding a bud of THCA-rich flower or using a product like Tosi’s pre-filled dugout, you’re not getting THC until you actually light it.

What About THCA in Concentrates?

You might also see THCA in products like:

  • THCA diamonds – These are highly purified crystals of THCA.

  • Rosin and live resin – These can contain THCA if they’re not decarbed.

These forms are great for those who want a potent experience and know how to handle concentrates.

Is THCA Legal?

Under the 2018 Farm Bill, hemp-derived products are legal federally as long as they contain less than 0.3% Delta-9 THC by dry weight. Since THCA isn’t psychoactive until heated, it can fall within this legal limit.

That’s why Tosi’s THCA products are 100% federally legal and can be shipped directly to most states. We only ship where it’s allowed, and we stay up-to-date with changing state laws.
