How Long Does Delta-8 THC Stay in Your System?

In recent years, delta-8 tetrahydrocannabinol, commonly known as Delta-8 THC, has garnered significant attention after the 2018 Farm Bill made it “technically” legal at the federal level in the United States. Similar to its more famous cousin, Delta-9 THC (the primary psychoactive component in marijuana), Delta-8 THC is a naturally occurring cannabinoid found in hemp plants, but it’s typically present in much lower concentrations than Delta-9. 

As a result of this change in the law, however, Delta-8 is now being marketed as a safe and legal alternative to Delta-9. For people seeking a legal buzz that won’t get them fired from work, this has left them with a slew of questions, such as:

  • What is Delta-8 THC? 
  • Will Delta-8 show up on a drug test? 
  • How long does Delta-8 stay in your system? 

This article will cover detection times, legal status, and common myths you might have heard about this new “legal weed.”

Key Takeaways

Detection Window in UrineOne to three days for infrequent users, up to 30 days or more for regular users
Influencing FactorsUsage frequency, metabolism, test sensitivity, dosage, hydration, body fat
Drug Test SensitivitySome tests may not specifically detect Delta-8, leading to false negatives
Legal ConsiderationsVaries by region; essential to check local laws
Recommended ActionConsult healthcare professionals for personalized advice; abstain from Delta-8 if concerned about drug tests

Understanding Delta-8 THC and Drug Testing

What is Delta-8 THC?

Delta-8 THC is structurally similar to Delta-9 THC, with a slight difference in the placement of a double bond in its molecular structure. This minor difference significantly impacts how it interacts with the body’s endocannabinoid system, resulting in different effects. Understanding this distinction is crucial when considering drug testing, as most standard tests are designed to detect Delta-9 THC and may not always differentiate between the two cannabinoids.

Delta-8 Drug Testing

The presence of Delta-8 THC in urine is a subject of concern for many users, especially those facing drug tests for employment or legal purposes. It’s essential to note that while some drug tests might detect Delta-8 THC, their primary target is usually Delta-9 THC. This can result in false positives or negatives, depending on the sensitivity and specificity of the test.

Factors Influencing Detection Times in Urine

The duration Delta-8 THC remains detectable in urine can vary based on several key factors:

  1. Frequency of Use:
    • Infrequent users may have detectable levels for one to three days.
    • Regular users can expect a longer detection window, potentially up to 30 days or more.
  2. Metabolism:
    • Individual metabolic rates play a significant role. Faster metabolism can lead to shorter detection times.
  3. Test Sensitivity:
    • More sensitive tests can detect lower levels of Delta-8 THC, extending the detection period.
  4. Dosage:
    • Higher doses of Delta-8 THC may result in longer detectability.
  5. Hydration and Body Fat:
    • Proper hydration and lower body fat percentage can aid in quicker metabolism and elimination of Delta-8 THC.

Legal Considerations

The legal status of Delta-8 THC varies widely, depending on your location. It’s imperative to stay informed about the laws in your area, as this will not only impact your consumption choices but also your approach to drug testing scenarios.


Given the complexities surrounding Delta-8 THC and drug testing, our primary recommendation is to seek advice from healthcare professionals, especially if you have concerns about an upcoming drug test. If the outcome of a drug test is critical for you, it may be prudent to abstain from Delta-8 products altogether.

Different Types of Drug Tests for Delta-8 THC

Understanding the various drug testing methods is crucial in comprehending how Delta-8 THC may be detected:

  1. Urine Tests:
    • The most common form of drug testing.
    • Can detect Delta-8 THC for up to 30 days after usage, depending on frequency and dosage.
  2. Blood Tests:
    • Less common for Delta-8 THC detection.
    • Offer a shorter detection window of up to 48 hours after use.
  3. Saliva Tests:
    • Useful for immediate detection but less effective for detecting past use.
    • Similar detection window to blood tests.
  4. Hair Follicle Tests:
    • Have the longest detection window, potentially up to 90 days.
    • Less commonly used due to higher costs and potential for false positives.

Each of these tests has its own sensitivity and detection window, making it vital to understand the specific type of test you may be subjected to.

Myths and Facts About Delta-8 THC Drug Testing

When it comes to Delta-8 THC and drug tests, there are several myths and misconceptions that need addressing:

  • Myth: Delta-8 THC is undetectable in drug tests.
    • Fact: While Delta-8 THC is different from Delta-9 THC, it can still be detected in drug tests, especially if the test is sensitive to THC metabolites.
  • Myth: You can easily fool a drug test if you’ve used Delta-8 THC.
    • Fact: Passing a drug test after using Delta-8 THC is not guaranteed. Factors like metabolism, frequency of use, and the type of test play significant roles.
  • Myth: All drug tests can differentiate between Delta-8 and Delta-9 THC.
    • Fact: Not all tests can clearly distinguish between the different THC compounds. This can sometimes lead to false positives.

Tips for Delta-8 THC Users Facing Drug Tests

For those who use Delta-8 THC and are concerned about drug testing, here are some practical tips:

  1. Understand Your Usage and Its Implications
    • Be aware of how often and how much Delta-8 THC you use. This can help you estimate the detection window in your case.
  2. Consider Your Metabolism and Lifestyle
    • Factors like metabolism, diet, and exercise can influence how quickly Delta-8 THC is metabolized and eliminated from your body.
  3. Stay Informed About Test Types
    • Knowing the type of drug test you will undergo can help you better understand the likelihood of detection.
  4. Legal Considerations and Compliance
    • Always stay up-to-date with the legal status of Delta-8 THC in your area to ensure compliance.
  5. Seek Professional Advice
    • Consult with healthcare professionals for personalized guidance based on your individual situation.


In conclusion, the detection of Delta-8 THC in urine can be influenced by a variety of factors, including the type and sensitivity of the drug test, the user’s metabolic rate, and their usage patterns.
