If you're a cannabis consumer or exploring THCa products for the first time, you might be wondering, “Will THCa show up on a drug test?” It’s a valid question, especially if you need to comply with workplace policies or other testing requirements. In this post, we’ll break down what you need to know about THC tests and THCa.

What is THCa?

First, a quick recap. THCa, or tetrahydrocannabinolic acid, is a non-psychoactive cannabinoid found in raw cannabis plants. When exposed to heat, THCa converts into THC—the well-known compound that produces the psychoactive effects commonly associated with cannabis.

While THCa itself doesn’t get you "high," it’s important to note how it interacts with drug tests.

Can THC Drug Tests Detect THCa?

The short answer? Yes, it’s possible for THCa to be detected on a drug test—but not directly.
Most standard drug tests are designed to detect THC and its metabolites, which are byproducts created when THC is processed in the body. What can cause a positive THCa urine test? When THCa is heated (through smoking, vaping, or cooking), it converts to THC. Once that happens, your body will metabolize it as THC, and it can trigger a positive result on a drug screening.

Even if you’re consuming THCa products in raw form (unheated), there's still a small chance that some conversion may occur during storage, processing, or ingestion, potentially leaving trace amounts of THC in your system. While this is less likely, it’s not a risk that can be completely ruled out.

Factors That Impact THC Drug Test Results


If you’re using THCa products, several factors could affect whether it shows up on a THC test:

  • Type of Test: The most common drug tests—like urine tests—are designed to detect THC metabolites. Blood, saliva, and hair tests also focus on THC and its byproducts.
  • Frequency and Amount of Use: Heavier or more frequent use results in more THC metabolites in your system, increasing the chance of detection.
  • Your Metabolism: Everyone processes THC differently. Factors like body fat, hydration, and metabolism can impact how long THC metabolites stay in your system.
  • Product Purity: THCa products may contain trace amounts of THC, depending on their source and manufacturing process. Always check for lab-tested products with detailed cannabinoid breakdowns to understand exactly what you’re consuming.

How to Pass a Drug Test for THC

If you’re concerned about drug tests, the best advice is to avoid using THCa products altogether. While Nova Hemp offers high-quality, lab-tested THCa products, we recommend caution and transparency to ensure you make the right choice for your situation.
For those who choose to consume, here are some tips to minimize risk:

  1. Read Product Labels: Opt for products with third-party lab testing that clearly outline THC and THCa content.
  2. Understand Your Test Window: THC metabolites can linger in your system for days or even weeks, depending on usage and testing methods.
  3. Use in Moderation: Less frequent use means a lower likelihood of detectable levels in your system.


However, it’s essential to keep in mind that no solution guarantees a negative drug test result.

Final Thoughts

At Nova Hemp, we prioritize educating our customers and promoting responsible cannabis use. If you’re subject to drug testing or have concerns about a positive test result, we advise against using our THCa products. While THCa offers exciting possibilities as a non-psychoactive cannabinoid, its potential to trigger a positive drug screening means it’s not the right choice for everyone.

A Guide to CBN: Effects, Benefits, and Products

CBN (cannabinol) is a cannabinoid formed when THC degrades through exposure to oxygen and heat over time. Unlike THC and CBD, CBN occurs naturally in small amounts and is considered non-intoxicating. It interacts with the body's endocannabinoid system through CB1 and CB2 receptors, though with weaker affinity than THC.

Research suggests CBN may offer several benefits: sedative effects that promote sleep (earning it the nickname "sleepy cannabinoid"), pain and inflammation relief through interaction with pain-signaling neurons, and appetite stimulation. CBN products are available as tinctures, gummies, edibles, and capsules.

When starting CBN, begin with low doses and gradually increase. Quality products should be sourced from reputable suppliers, with options ranging from basic CBN tinctures to full-spectrum gummies that combine CBN with other cannabinoids for enhanced effects through the entourage effect.
