Key Takeaways

  • THCA, or tetrahydrocannabinolic acid, is a non-intoxicating component of raw marijuana.
  • On the other hand, THC (tetrahydrocannabinol) causes marijuana’s typical psychoactivity.
  • Depending on the kind of test being used, THCA may appear on a drug test.
  • Non-decarboxylated THCA, which is the raw form, may not be detected by all drug tests.
  • Different places have different laws regarding THCA.
  • There are methods to expedite the elimination of THCA from your system if needed.

What is THCA?

THCA, short for tetrahydrocannabinolic acid, is a naturally occurring cannabinoid that can be found abundantly in both cannabis and hemp plants, particularly when they are in their raw and unheated state. THCA is notable for being a non-intoxicating substance, in contrast to its more well-known counterpart, THC (tetrahydrocannabinol). It’s crucial to emphasize that THCA does not induce the conventional psychoactive “high” commonly associated with THC usage, making it an intriguing component of the cannabis plant.

The key differentiation between THCA and THC lies in their respective properties and effects. THCA serves as the precursor to THC, undergoing a chemical transformation called decarboxylation when exposed to heat. Cannabis’s well-known psychoactive effects result from this process, which also converts THCA into THC. In contrast, THCA, in its raw form, maintains its non-intoxicating nature, offering unique potential benefits without the typical effects associated with THC.

How is THCA Different from THC?

THCA differs significantly from THC in several crucial ways. Above all, THCA is not psychoactive; that is, it does not produce the buzz that is frequently linked to THC use. This difference results from the way THCA interacts specifically with the body’s cannabinoid receptors.

THCA shows a preference for binding to TRP ion channel receptors in the endocannabinoid system, in contrast to THC, which primarily binds to CB1 receptors. One important reason THCA does not exhibit psychoactivity is because of this differential receptor interaction.

The fundamental contrast between THCA and THC lies in their respective functional groups. THCA contains a carboxyl (COOH) functional group, whereas THC features a hydroxyl (OH) functional group. Compounds’ reactivity and other chemical properties are influenced by functional groups in organic chemistry.

The carboxyl group found in THCA does not engage with cannabinoid receptors, specifically CB1 and CB2, which elucidates why THCA does not produce psychoactive effects. On the contrary, THC’s hydroxyl group exhibits a strong affinity for these CB receptors, resulting in the well-documented psychoactive properties of THC.

However, an intriguing aspect of THCA is its propensity to convert into THC when subjected to heat, air, or light. This transformation process, known as decarboxylation, begins shortly after cannabis material is harvested. During the drying and curing stages, a substantial portion of THCA naturally converts into THC. The highest degree of conversion occurs when cannabis is heated, which is why the usage of heated THCA products, such as burning THCA flower, using THCA concentrates, or using heated THCA goodies, can potentially lead to a positive result on a drug test.

In addition, THCA is not treated the same way legally as THC is. According to the 2018 Farm Bill, cannabis containing less than 0.3% THC, commonly referred to as hemp, is considered legal, along with its derivatives. Since THCA naturally occurs in hemp, it is essentially federally legal under this definition.

However, THC has a more complicated legal status. While the Controlled Substances Act categorizes THC as a Schedule I drug, amendments have been made to exempt “tetrahydrocannabinol” derived from hemp. It’s worth noting that both hemp-derived THC and THC from marijuana hemp are chemically identical, adding a layer of complexity to the legal landscape surrounding THC.

In summary, THCA and THC may share a chemical lineage, but their distinct properties, including psychoactivity, receptor interaction, and legal status, set them apart. Comprehending these distinctions is essential for people navigating the cannabis industry, especially with regard to drug testing and legal compliance. 

Does THCA Show Up On a Drug Test?

Yes, depending on the kind of test being used, THCA may appear on a drug test.  However,  the question of whether THCA shows up on a drug test is not a straightforward yes or no due to two key factors. Firstly, THCA is a complex compound with dual characteristics, and secondly, drug tests primarily target THC metabolites rather than THCA.

In its natural form within live cannabis, THCA may not be detectable by drug tests since it is not a THC metabolite. Heat, however, transforms THCA into THC.

THC is metabolized in the liver into two different forms: 11-hydroxy-tetrahydrocannabinol (11-OH-THC), which is then converted into 11-nor-9-carboxy-tetrahydrocannabinol (THC-COOH) by the liver. Drug tests commonly identify THC-COOH in urine.

There is a possibility for THCA to show on a drug test, albeit not fully understood. Given its similarity to THC, THCA might undergo similar metabolic processes in the liver, potentially leading to the presence of THC metabolites in drug tests.

Is It Possible for a Drug Test to Detect Non-Decarboxylated THCA?

The pure, unadulterated form of THCA that is extracted from freshly harvested cannabis is known as non-decarboxylated THCA. The presence or absence of it on a drug test depends on the type of test used. Standard drug tests primarily look for THC metabolites, but more sensitive tests may detect THCA and other cannabis compounds.

Can You Fail a Drug Test If You Take THCA?

Yes, THCA has the potential to cause you to fail a drug test, especially if the test is sensitive to THCA or if you have used products containing THCA in large quantities. We say yes as a precaution. Taking THCA does not guarantee automatic failure on a drug test; the outcome depends on the type of THCA product used. Smoking or using heated THCA products carries a higher risk of failing the test due to the conversion of THCA into THC through heat. It is unknown if the liver converts THCA into detectable THC metabolites, so using THCA raw may be one way to evade detection. 

It is best to be cautious when it comes to job security. It is not worth the risk, even though THCA might or might not result in a failed drug test. To be safe, it’s best to steer clear of hemp products containing “tetrahydrocannabinol.”

How is THCA Detected on a Drug Test?

Numerous techniques, such as urine, blood, and hair tests, can identify THCA on a drug test. These tests can identify THCA metabolites or the presence of THCA itself. It’s essential to know which type of drug test you are taking and how sensitive it is to THCA to gauge the potential for detection.

How Long Does THCA Stay in Your System?

Potency, dosage, frequency of use, body fat, mode of usage, and metabolism are some of the variables that affect how long THCA stays in your system. Frequent use of high-potency THCA products, slow processing, and higher body fat may result in longer detection times.

While there is limited research on how long THCA specifically stays in the system, we can make some inferences based on studies of THC metabolites. An investigation conducted in 2001 discovered that THC-COOH, a metabolite of THC, can be found in serum at 14–49 ng/ml. It typically peaks 1-3 hours after use and remains detectable for up to 74.3 hours.

Depending on the body fluid being tested and the administration route, the duration of THC-COOH detection may change:

  • In saliva, THC-COOH can be detected for up to 48 hours.
  • In the blood, it may remain present for up to 20 hours.
  • In urine, THC-COOH can be detectable for 3-4 days, but in heavy users, it may extend up to 45 days.
  • Hair follicles can retain THC-COOH for as long as 90 days, especially with frequent use.

It’s important to note that these timeframes are typically associated with first-time use, and detection windows may increase with a higher frequency of use. Therefore, it’s crucial to consider these factors when assessing how long THCA or its metabolites might stay in your system for drug testing purposes.

What Drug Tests Can Detect THCA?

Various drug tests can potentially detect THCA, considering the evolving landscape of cannabis use and the need for drug screening. It’s essential to note that marijuana remains illegal in many regions, making its use prohibited.

Here are the types of drug tests that can detect THCA:

1. Urine Tests

  •    These tests are common due to their simplicity, cost-effectiveness, and quick results.
  •    Urine tests come in two varieties: gas chromatography-mass spectrometry (GC-MS) and immunoassays (IA).
  •    IA tests are less sensitive and may produce false positives, while GC-MS tests are more reliable but are expensive and time-using.
  •    Depending on how frequently a urine test is used, the detection window may extend from a few days to more than a month.
  •    A THC level of 50 ng/ml or higher typically results in a positive drug test. Lower THC levels may yield negative results, but a confirmation test with higher sensitivity may be required.

2. Saliva Tests

  •    Saliva tests detect recent drug use, with a detection window of 1-3 days.
  •    Mouthwashes that neutralize saliva can remove drug metabolites from the mouth, though they may be contaminated easily.

3. Blood Tests

  •    THC metabolites remain in the blood for a relatively short period (3-7 days).
  •    Blood tests are less common due to their invasive nature, and THC levels in blood plasma decrease 3-4 hours after use.

4. Tests on Hair Follicles

  •    The longest detection window, up to ninety days, is found in hair follicle tests.
  •    They are ineffective at identifying light or recent cannabis use.

The selection of a drug test could be influenced by variables like the testing conditions and the necessary detection window. Thinking about THCA detection in drug tests requires knowledge of the various testing techniques and their limitations.

Is THCA Legal?

Yes, according to the 2018 Farm Bill, THCA is indeed permitted at the federal level. Nonetheless, this law gives states the authority to create rules governing the cultivation and processing of hemp within their borders. 

Therefore, THCA legality varies from region to region. You should research hemp laws in your state or the state you plan to visit to ensure compliance.

How to Get THCA Out of Your System

To eliminate THCA from your system before a drug test, consider the following methods:

1. Abstain from THCA Products

 The most effective way to prevent THCA detection is to avoid products containing THC-like cannabinoids.

2. Exercise  

 Exercise helps burn extra fat, which releases cannabinoids that have been stored for excretion. Cannabinoids bind to fat molecules.

3. Stay Hydrated

 Drinking plenty of water promotes urination, which facilitates the removal of cannabis metabolites from your system.

4. Eat a Balanced Diet

A balanced diet may help flush out cannabis by slowing down the breakdown of fatty molecules, leading to a gradual decrease in cannabinoid concentration in body fluids.

These methods can aid in expediting the clearance of THCA from your system, but their effectiveness may vary based on individual factors and the timing of the drug test, and there are no guarantees with these methods. To prevent THCA detection, it is important to seek personalized advice from a healthcare professional.
