How Long Does THCA Stay in Your System?

As cannabis products continue to gain acceptance among the general population, many individuals are seeking out compounds such as THCA for their perceived health benefits—without the high. However, although THCA is non-psychoactive, concerns abound regarding how long it stays in the system. 

Recent studies indicate cannabinoid metabolites, such as THCA, could be traced depending on the quantity consumed and an individual’s metabolism. Whether you’re taking a drug test, monitoring your health regimen, or merely interested in how your body processes cannabinoid compounds, understanding THCA’s timeline in the body is key. 

If you’re planning to take an examination for drugs, or you’re looking for information on the effects of THCA, this guide will give you all the information you require.

What’s THCA, and How Does It Work?

It’s a naturally occurring tetrahydrocannabinolic acid compound found in raw cannabis. It’s a non-psychoactive cannabinoid. This means that it does not give you a “high” associated with marijuana. When exposed to temperatures (via smoke, vape, and making food), THCA converts into THC by a process known as decarboxylation.

Although THCA isn’t bound to your brain’s CB1 receptors, it does pose an interesting chemical energy, as drug tests typically don’t discern between THCA and THC. Both are metabolized to the same byproducts within the body. That’s the reason why drinking cannabis raw can result in positive results on tests.

How the Body Processes THCA?

It is important to examine how the body absorbs, processes, and removes THCA to determine the length of time it remains visible.

Absorption

THCA is absorbed into the body via:

  • Ingestion (e.g., raw cannabis, capsules, tinctures)
  • Topical application
  • Sublingual usage (under the tongue)

Vaping or smoking cannabis doesn’t give THCA in its natural form. Instead, the heat transforms it into THC.

Metabolism

THCA undergoes minimal processing within the body. Because of its acidic form, it’s not able to attach to receptors for cannabinoids similar to THC. It is believed that the majority of THCA moves through the system via the bile and urine with minor alteration, until a partial conversion into THC occurs in rare digestive conditions.

Elimination

Being a lipophilic substance, THCA can be stored in fat cells. It could remain in your body for a longer period if you are a person with higher body fat levels or if you regularly consume cannabis.

Does THCA Show Up in Drug Tests?

The majority of the tests for drugs that are commonly used, such as urine and blood tests, saliva tests, and hair tests, do not test for THC directly. Instead, they look for THC components, including THC-COOH.

But it is the case that if THCA gets subjected to heat (through cigarettes, vapor, or cooking), it will transform into THC. After conversion, it can create psychoactive effects, and also be metabolized into detectable substances, making positive results on drug tests possible.

How Long Does THCA Stay in Your System?

The length of THCA in your body depends on many variables, including the type of test you are using. Here’s how:

Urine Test

Urine tests are the most popular method to detect cannabis use because most people are confused and ask, “is THCA detectable in urine?”. THCA compounds may remain inside your urine during the following periods:

  • Occasional user: 1–3 days.
  • Moderate users: 7–10 days.
  • Chronic/heavy users: 30+ days.

Blood Test

The blood tests can identify recent use of cannabis and are commonly utilized in medical or legal contexts. THCA is typically visible in blood for about 1–2 days. However, people who are heavy users could test positive for as long as one week.

Saliva Test

Saliva testing is often utilized for roadside drug tests since it detects use in recent times. THCA is usually detectable in saliva for 24 to 72 hours following consumption.

Hair Test

How long does THC stay in your hair? Hair follicle tests offer the longest detection time because they can detect cannabis use for as long as 90 days. However, they aren’t as popular because they’re costly.

Factors Influencing THCA Detection Time

Many factors influence the length of time THCA remains within your system:

  • Metabolism: Faster metabolisms eliminate cannabinoids quicker.
  • The Body Fat: THCA metabolites are fat-soluble, which means they’re kept in fat and then released slowly.
  • Use Frequency: Occasionally, users remove THCA faster than heavy users.
  • Hydration: Drinking enough water helps eliminate the metabolites.
  • Type of drug test: Hair tests are detected for months, while blood tests are detected for hours.

THC vs THCA Differences for Drug Testing

Knowing the difference between THC and THCA is crucial for anyone who is concerned regarding cannabis or drug testing usage. Let’s look at the differences:

AspectTHC (Tetrahydrocannabinol)THCA (Tetrahydrocannabinolic Acid)
Psychoactive EffectYes, it produces a highNo, non-psychoactive
Metabolic ConversionConverted from THCA when heatedDecarboxylates into THC when heated
Drug Test DetectionYes, detected in most drug testsYes, shows up in drug tests after conversion to THC
Therapeutic BenefitsPain relief, appetite stimulation, etc.Anti-inflammatory, neuroprotective, etc.
Duration in SystemCan stay in the system for 1–30 days, depending on use and body compositionCan remain in the system for days to weeks, depending on metabolism and body fat

THCA false-positive result?

While rare, however, the possibility of the possibility of a THCA fake positive drug test can occur.

  • Certain over-the-counter or prescription medicines can result in an incorrect positive result in a drug test. This includes NSAIDs such as ibuprofen and naproxen, proton pump inhibitors, and Efavirenz. 
  • Studies have proven that passive inhalation of secondhand smoke from a user of THCA can result in positive drug screens, because the inhaled form could be THC due to heating.
  • Foods containing hemp seed oil have been proven to give false-positive results on screening for drugs.

Natural Ways to Detox THCA

If you’re trying to cleanse from THCA, take a look at these suggestions:

  1. Drinking lots of fluids helps your kidneys rid themselves of the toxins.
  2. Physical exercise burns fat and releases stores of THCA in fat cells.
  3. A healthy diet of antioxidants and fiber helps support your body’s natural detoxification processes.
  4. Do not continue using this, as the most effective way to cleanse is to quit drinking cannabis in all its forms.
