What Is THCA Flower?

Tetrahydrocannabinolic acid (THCA) is a naturally occurring cannabinoid and the acidic form of fan-favorite THC. That’s the easy definition, but what about THCA flower, the most popular form of THCA? What is THCA flower?

THCA flower is hemp-based and contains high levels of THCA. In this raw form, THCA is non-psychoactive, offering effects many say are similar to CBD. But when THCA gets heated, it converts from its acidic form into THC, a process called decarboxylation. While it sounds fancy, decarboxylation simply happens when THCA flower is set ablaze—you know, when you light a delicious, terpy THCA preroll and smoke THCA-infused buds.

How to Use THCA Flower?

If it’s your first time enjoying the classic smoking experience of THCA flower, you might need a little crash course, a quick “how to” guide.

First, make sure you have all the necessary smoking accessories. You’ll need:

  • Herb grinder
  • Rolling papers
  • (or) Pre-rolled cones
  • Rolling tray
  • Ashtray
  • Smoke Buddy (for discreet smoking)

Then, separate the THCA flower from the stem and place the raw, sticky buds into the grinder. Grind the flower and shake the contents out onto a rolling tray. Don’t forget to check your grinder’s kief compartment; that’s where some extra potent flower ends up. From here, craft your own pre-roll or stuff a pre-rolled cone (the optimal choice for those who can’t roll). Finally, smoke away—in a welcomed place, of course.

Frequently Asked Questions

What is THCA?

Tetrahydrocannabinolic acid (THCA) is the chemical precursor to THC. THCA naturally occurs in all cannabis plants and needs to be heated to transform into THC—this process is called decarboxylation. In its raw state, THCA is non-psychoactive. But, once they turn into THC, THCA molecules, like those in THCA flower, deliver all the classic effects of psychotropic THC.

How is THCA flower made?

THCA flower is made through careful cultivation practices that retain the hemp plants’ natural properties. These plants are ripe with THCA, and, if prepared properly, will deliver potent amounts of THCA in your preroll.

What is the difference between THCA and THC?

The difference between THCA and THC is that THCA morphs into THC through a process called decarboxylation. THCA, in its natural state, can be consumed but doesn’t provide any psychoactive effects, like THC. Many adults equate THCA’s effects to those from CBD—relaxing, soothing, and wellness-based.

How do you grow THCA flower?

Hemp can be tricky to grow, let alone cultivate into a smokeable product. You have to develop the hemp plant around all-natural, soil-enriching compounds. Plus, you need to run the raw buds through lab testing to prove purity and potency. All this can be a pretty lofty process for a backyard grower. So, when in doubt, trust the professionals and only buy THCA from respected, reliable brands that publish Certificates of Analysis alongside their products.

How do you smoke THCA flower?

You can smoke THCA flower like any other cannabis buds. First, grind the flower using a herb grinder, empty the grinder on a flat surface like a rolling tray, and craft the ground buds into a preroll with rolling papers, or pack them into a prerolled cone.

What is decarboxylation?
