Have you heard about THCV? If you have not, you likely will soon. This cannabinoid is slowly but surely gaining momentum in the cannabis marketplace as a “diet weed” with purported hunger suppressant qualities.

THCV is a unique cannabinoid — a homolog of THC with intoxicating effects in larger doses.

Due to this close relationship with THC, a reasonable question those subject to drug testing may be wondering is: how long does THCV stay in your system?

There are widely accepted consensus on whether or not THCV can cause a positive drug reading.

Anecdotally, some users claim that using THCV will allow you to pass a drug test. However, studies have shown that THCV can be detected in urine samples two weeks after consuming it. 

There is more to this cannabinoid than meets the eye. Read on to find out more!

What is THCV? 

As you may already know, THCV is one of 113 separate phytocannabinoids found in varieties of hemp. 

THCV is a cannabinoid first discovered in the early 1970s and is relatively common in cannabis plants. Though it is not as popular as CBD and THC (yet), we have years of research to support its imminent claim to fame.

THCV was discovered five years later than THC in 1973. However, it has not been until recently that THCV has gained some pretty widespread attention from researchers and cannabis enthusiasts.

There are also a handful of cannabis strains on the market that have high percentages of THCV:

  • Durban Poison originates from Durban, South Africa, with a naturally occurring THCV cannabis concentration nearly 1%. It is reputed for its appetite suppressing and energizing effects.
  • Doug’s Varin, likely the highest THC strain available today, is also rich in THCV, ranging from 3% to 6% THCV.  
  • Pink Boost Goddess is another specialized strain to emerge from THCV’s recent hype. This strain contains 4.24% THCV along with 18.7% THC. 
  • Pineapple Purps, known for its energetic and euphoric effects, has a very high THCV profile, with some lab results measuring the cannabinoid at 4% of the flower’s dry weight. 
  • Jack the Ripper is a strain known to consistently test at 5% THCV or higher, with a THC content that ranges from around 15-25%. 

How does THCV work in the body?

THCV is still somewhat of a mystery, but this is what we know so far…

Like THC, CBD, and other cannabinoids, THCV exerts therapeutic effects through interaction with chemical receptors in nearly every system of the body.

The two primary chemical receptors are called CB1 and CB2, which make up what is known as the Endocannabinoid System (ECS).

This system regulates a wide range of our body’s functions required for optimal health.

CB1 receptors are found throughout the body but are concentrated in the brain and nervous system, while CB2 receptors are more prevalent in the immune system.

THCV acts as an antagonist to CB1 receptors at low doses, meaning it binds to the same receptors like THC but blocks them instead of activating them.

At higher doses, however, THCV activates both the CB1 and CB2 receptors and exhibits effects that more closely resemble THC.

This results in enhanced euphoric and cognitive impact along with the therapeutic value.

Will THCV show up on a drug test?

Since THCV is an analog of THC, they are very closely related. So much so that THCV consumption will likely result in a failed drug test. 

Employers, probations, and most other organizations rely on a urine test to determine whether or not an individual has been using marijuana recently.

THC is the cannabinoid responsible for triggering a positive result, but indirectly. See, urine tests are not looking for the presence of THC in a person’s urine.

Instead, they are looking for THC-COOH, a metabolite that breaks down THC in the body and ends up in the urine.

Although THC-COOH metabolizes delta 9 THC, it also metabolizes all THC cannabinoids.

Therefore, if you take delta 9, THCV, or another THC-based cannabinoid-like delta 8, THC-O, delta 10, or THC-P, you are at risk of failing a drug test, as your body will need to release THC-COOH to process the cannabinoid.

In addition, drug tests often can not differentiate between illegal and legal THC cannabinoids since a positive result is a positive result that can affect your employment, probation, or whatever applies to your reason for being tested.

In terms of saliva, blood, or hair testing, there is not a lot of research available.

However, if you do not want to take a chance, it might be best to avoid cannabis-derived products altogether.

THCV: factors to consider

There are hundreds of different cannabinoids, but most drug tests detect THC, the active ingredient in marijuana.

Various factors will influence the length of time that cannabinoids like THC stays in your system, such as your frequency of use, body mass, gender, metabolism, and hydration.

Again, it is probably best to avoid THCV if you might be subject to drug testing since the risk is just too high of failing.

However, if you already have consumed THCV distillate and have a test coming up, there are some factors to consider that can help determine the potential outcome.

The four main factors that determine how long THCV stays in your system are:

  1. How much THCV you have taken.
  2. How regularly you use THCV.
  3. The method by which you take THCV.
  4. The other cannabinoids and terpenes that you combine with THCV.

If you only had a THCV dosage a couple of days ago, there is a good chance you may be in the clear.

But if you are a daily user who consumes a good amount of THCV, it may take over a month before your test will come back negative.

It is also essential to consider that THCV is not the only federally legal hemp cannabinoid that can result in a failed drug test.

For example, Delta 8 THC, Delta 10 THC, THC-O, and THC-P can all cause the same response. 


The word is getting out about this appetite-curbing, energy-boosting powerhouse, and THCV promises to be one of the cannabis industry’s following major cannabinoids.

Currently, there are few strains and products on the market that contain significant levels of THCV, but thanks to consumer interest, it seems like that might be changing.

Like most minor cannabinoids, THCV research is still underway.

The jury is also out about whether or not it can interfere with a drug test result – that is, if you are someone who gets drug tested for work, probation, or any other reason.

Therefore, it is probably best to avoid THCV products until more definitive research has been done on this cannabinoid.
