THCA is the acidic form of tetrahydrocannabinol, the primary psychoactive component of cannabis plants. All cannabinoids exist in an acidic form until they’re activated by a process called decarboxylation, which removes the acidic carboxyl group from the molecule. 

Decarboxylation, also called decarbing, is achieved by heating the flowers. Smoking or vaping hemp or cannabis buds automatically decarbs them. Edibles chefs typically heat raw cannabis in the oven before making infusions for medicated food.

In the form of THCA, the molecule doesn’t produce the same intoxicating effects as regular THC. Instead of making strong bonds with endocannabinoid receptors, THCA produces its effects by interacting with the cytokine interleukin 10 (IL-10) and cyclooxygenase enzymes (COX-1 and COX-2). This means that consumers can get some of THC’s unique benefits without risking uncomfortable sensations like anxiety, paranoia, or couch-lock.

While both THCA and CBD are arguably “non-psychoactive,” CBD is the decarbed form of cannabidiol and can interact with endocannabinoid receptors, especially in the immune system.

THCA vs. CBD: Which One Is Right for You

THCA shares many therapeutic properties with both regular THC and CBD. THCA’s potential benefits include:

• 
  Reducing nausea and vomiting
• Increasing appetite (CBD tends to act as an appetite suppressant.)
• Exhibiting similar neuroprotective qualities as CBD
• Lowering inflammation and pain by inhibiting COX-1 and COX-2 enzymes
• Inhibiting tumor growth
• Combatting metabolic disorders and obesity

Partial decarboxylation also occurs when buds are stored or exposed to light for an extended period. Most dried cannabis flowers will have a mixture of THCA and THC. If you eat raw cannabis buds, you could still experience mild psychoactive sensations. 

However, you can find several products on the market that offer the benefits of THCA without any intoxicating effects. The most common THCA products available are oil or alcohol-based tinctures. You can take either type of tincture directly or mix it into uncooked foods. Alcohol-based tinctures are ideal for adding to beverages.

THCA diamonds are a concentrated crystalline form of THCA that can be up to 99% pure. THCA diamonds are typically odorless and flavorless, and you can use them in much the same way you would with tinctures.

Additionally, breeders are now offering hemp flower with high concentrations of THCA. 

But keep in mind that if you smoke, vape, dab, or cook with any THCA product, you’ll convert the cannabinoid to traditional THC and experience the same psychoactive effects you would get from consuming regular cannabis buds or concentrates.

So, which one is best for you: THCA or CBD? You can take CBD and THCA concurrently, but the ideal ratio depends on your unique circumstances. When in doubt, consult with a licensed 420-friendly physician to find out if THCA, CBD, or a combination of both would be best for you.
