Will THCV Make You Fail a Drug Test?


  • THCV is a minor cannabinoid found in some strains of cannabis.
  • THCV is not typically tested for in drug tests.
  • THCV is not likely to cause a false positive on a drug test for THC.
  • However, the use of high-THC cannabis products could lead to a positive drug test.

Cannabis smokers in the United States love the new wave of federally legal psychoactive cannabis strains flooding the market. One of the most popular options is THCV (tetrahydrocannabivarin.) The strain offers many benefits, including its positive effects on insulin and blood sugar. 

With that said, can you fail a drug test after using THCV? There’s nothing worse than worrying about failing a drug test. It can destroy your career ambitions and lead you to the wrong side of the law. 

In this article, we’ll look at THCV and whether you can fail a drug test after using it:

What Is THCV?

THCV, short for tetrahydrocannabivarin, is a cannabinoid like delta-8 and CBD. Therefore, it has a unique ability to bind to cannabinoid receptors throughout your body via the endocannabinoid system to affect the way we function and feel during the day. 

However, THCV is a minor cannabinoid, meaning you won’t feel the effects if you consume it in its raw forms, such as raw flower or spectrum hemp. As a result, it’s similar to delta-8 THC. So what is the difference between THC and THCV? They have a lot in common, as you might expect. 

The names are almost identical because they share a similar molecular structure, yet THCV is a minor psychoactive cannabinoid. Although THCV offers weaker effects than THC, there are still many benefits that give THCV its value. 

Can You Fail a Drug Test From THCV?

The short and simple answer is yes, you can fail a drug test after using THCV. Typically, THCV is mixed with other compounds—such as delta-8, delta-9, and delta-10. Therefore, it may trigger a dreaded failed drug test. 

So it’s wise to avoid smoking THCV and using THCV gummies if you have a drug test coming up. Sorry to be the bearer of bad news. 

Still, here are a few things you should know:

  • If you consumed a small amount of THCV over five days ago, you could have a stronger chance of passing the test. 
  • THC-COOH often remains in the body for up to 6 weeks—so a drug test may detect it for up to 6 weeks. However, you may be fine if you used THCV over six weeks ago. 
  • If you’ve consumed moderate to heavy doses of THCV in the past month, you should wait a month before attempting another drug test.

What Factors Can Trigger a Failed Drug Test?

Failing a drug test isn’t always straightforward. There are often many factors that can trigger a failed test. Here are some of the most common reasons for failed drug tests:

1. The Dosage and Strength 

THCV products have different strengths, so you should gauge their strength before consuming THCV, especially if you have an upcoming drug test. The amount of THCV you consume determines how much THC-COOH your body must break down. The more THC-COOH your body creates, the greater chance that you’ll fail a drug test. 

2. The Delivery Method 

How you deliver your THCV can have a massive impact on how it affects a drug test. For example, THCV gummies stay in the body the longest. Although they provide the most prolonged side effects, you should avoid them if you have a drug test shortly. Moreover, THCV vaping and smoking flowers enables your body to break down THCV more easily, which is better if you have an upcoming drug test. 

3. How Often You Use It 

How often you consume THCV cannabis products can determine whether or not you fail a drug test. For example, if you use THCV products daily, you’ll have a higher chance of failing a drug test. However, if you only consume THCV products once weekly, you’ll have less chance of failing a drug test. 

4. Your Body and Physique 

Your body type and physical condition play a significant role in whether you pass or fail a drug test after consuming THCV. Everyone’s body is different; therefore, everybody removes cannabis from their bloodstream at different paces. It’s difficult to determine how fast your body will withdraw THCV without some trial and error. 

How Do THCV Drug Tests Work?

There is no difference between testing for THC and THCV. In both cases, employers, authorities, and other organizations use urine tests to determine whether someone has consumed cannabis. Urine tests don’t look for delta-9 THC automatically, but they look for the presence of THC-COOH—which breaks down THC in your body. 

Although THC-COOH metabolizes delta 9 THC, it also metabolizes all other cannabinoids. So if you’re taking delta-8, delta-9, delta-10, THC-P, and THCV—you risk failing a drug test. However, a drug test doesn’t differentiate between legal forms of THC cannabinoids and illegal forms of THC, so it can affect your employment and future opportunities (even if you consume legal forms of THC.)

If you have an upcoming drug test, you should avoid all cannabis strains and types, even if they’re legal.

Can You Remove THCV From Your System Faster?

Now you understand that you can still test positive for cannabis when using THCV, you probably want to know whether you can remove it from your system faster. In truth, there’s no definite way to flush THCV from your body, but the following methods may come in handy:

  • Drink cranberry juice: Cranberry juice is one of the best natural diuretics; it’s excellent for bladder health. So it’s a superb option for removing THCV faster from your bloodstream, but there’s no certainty that it’ll work quickly. 
  • Drink tonnes of water: Drinking lots of water is a superb way to flush THCV from your system. However, drinking too much water can cause a red flag on your drug test and invalidate it. So be wary of drowning your body in water. 
  • Try zinc: Some cannabis smokers use zinc to remove THC from their bloodstream faster. However, zinc supplements can cause a red flag and invalidate your drug test. 
  • Use weed detox products: There are countless weed detox products on the market. Some weed detox products make bold—often unfounded—claims about removing cannabis from someone’s bloodstream. The industry is barely regulated, so you should be wary before relying on detox products before a drug test. 

Are There Any Differences Between THCV and Delta-9 THC?

You may be wondering how THCV compares to delta-9 THC. There are strong similarities between the two. Here are some examples of similarities and differences:

  • Delta-9 THC has a boiling point of 315 degrees, whereas THCV has a boiling point of 428 degrees. 
  • THCV’s high lasts around half the time as delta-9 THC. So it’s not ideal if you’re looking for a prolonged high. Furthermore, you must consume high THCV doses to feel any psychoactive effects.
  • Delta 9 THC and THCV are homologs of each other. Therefore, their chemical structure is incredibly similar, yet it’s different enough to have their benefits and characteristics. 

Frequently Asked Questions (FAQ)

In Summary

As the cannabis industry grows, THCV will become more popular because of its excellent benefits. That said, it won’t stop you from failing a drug test. If you have an upcoming drug test, you should skip all cannabis products to avoid failing the test. 

It’s the only way to be confident.
