THCA is non-psychoactive and does not directly trigger a positive drug test. However, when exposed to heat, it transforms into THC, which can be detected. Drug tests typically screen for THC-COOH, a THC metabolite, meaning that consuming THCA hemp flower products could still result in a failed test. In essence, THCA may appear on a drug test due to its conversion into THC, which is traceable.
What are the benefits of THCA?
THCA is gaining attention for its potential health benefits, with many exploring its use for wellness purposes. One of its most attractive qualities is its non-psychoactive nature, allowing individuals to experience the advantages of the cannabis plant without the associated high. This makes it a popular choice for those seeking the therapeutic aspects of cannabis without psychoactive effects.
Although research on THCA is still in its infancy, early findings suggest it may offer neuroprotective and antioxidant properties. Many users report that THCA helps alleviate discomfort and supports overall wellness. Since THCA does not bind directly to cannabinoid receptors, its effects are typically milder than THC’s but can still be meaningful.
As interest grows, THCA is increasingly seen as a way to harness cannabis's benefits while remaining clear-headed, making it an appealing option for those looking to explore cannabis for wellness without the intoxicating effects.
Does THCA Get You High?
The length of time THCA remains in your system depends on factors such as potency, dosage, and individual metabolism. Once THCA converts to THC-COOH, it can be detected for the following durations:
- Urine: 3-4 days for infrequent users and up to 45 days for frequent users.
- Blood: Up to 20 hours.
- Hair Follicles: Up to 90 days.
- Saliva: Up to 48 hours.
Understanding different types of drug tests
The most widely used drug tests include urine, blood, saliva, and hair tests, each with distinct methods for identifying substances in the body. All primarily target THC, the psychoactive compound found in cannabis.
Urine tests are the most prevalent, designed to detect THC metabolites. They typically identify usage within a few days, but detection windows can be longer for individuals with higher body fat, as THC is stored in fat cells. Blood tests are more precise and usually employed to confirm recent use, as they only detect THC for a short period.
Saliva tests are comparable to blood tests, focusing on detecting recent use, often within the past 24 hours. In contrast, hair tests provide a much longer detection window, capable of identifying drug use for up to 90 days.
However, concerns about fairness and accuracy have been raised with hair tests, as they may disproportionately yield positive results in individuals with darker or thicker hair due to differences in hair composition.

What Drug Tests Can Detect THCA?
Although drug tests do not specifically target THCA, it can still indirectly lead to a positive result under certain circumstances. This happens because THCA converts into THC when exposed to heat. If raw cannabis or THCA-rich products are heated during or before consumption, some THCA may transform into THC.
Once THC enters the body, even in small amounts, it is metabolized into THC-COOH, the compound most drug tests are designed to detect. Factors such as the quantity consumed, the method of consumption, and individual metabolism—especially in those with higher fat content, where THC metabolites tend to accumulate—can increase the likelihood of detection.
However, this scenario is relatively rare and typically requires significant conversion of THCA into THC under specific conditions. The probability of a positive drug test resulting from THCA use depends on variables like dosage, heat exposure, and metabolic rate. For those facing critical drug tests, it’s important to be mindful of these risks.
Common Drug Testing Methods:
- Urine Tests: The most frequently used, as THC metabolites remain detectable for extended periods.
- Saliva Tests: Ideal for identifying recent use, particularly through oral consumption.
- Blood Tests: Less commonly used due to THC's short presence in the bloodstream.
- Hair Follicle Tests: Capable of detecting THC up to 90 days after use, though infrequently administered.
- Breath Tests: Focused on active THC detection and not as effective for identifying THCA.
