Rapid Marijuana Saliva Test Detects Immediate Use within Minutes

A new, rapid test can detect recent marijuana use in the saliva of users within five minutes, according to a new study. Unlike standard drug tests, the test can also distinguish immediate use (within 12 hours) from less recent use.

The new technique, which was tested with 43 users of marijuana (or cannabis) and 43 non-users, features sensors that detect the drug far faster than standard tests. The test’s speed could prove useful in situations such as roadside safety and precautionary self-testing, the study authors say.

With further improvements, the test could one day help meet the need for a fast, accurate, and more time-specific cannabis test as the drug increasingly becomes legalized for both medicinal and recreational purposes.

The testing platform was designed and evaluated in a new study published in the October 20 issue of Science Translational Medicine.

Rapid Testing in the Age of Legalization

Cannabis is one of the most widely consumed psychoactive drugs, with an estimated 43 million users in the U.S. and 200 million users worldwide, according to the 2018 National Survey on Drug Use and Health and the 2021 United Nations World Drug Report .

Although cannabis has been largely prohibited for decades, restrictions on the drug have gradually loosened in recent years in several countries. Advocates have pointed to the drug’s medicinal potential as a treatment for chronic pain, glaucoma, post-traumatic stress disorder, and other conditions.

Meanwhile, federal or state laws that legalize recreational use have appeared in countries such as the Netherlands, Canada, and the U.S. As of 2020, cannabis has been legalized in 18 U.S. states for recreational use and in 36 U.S. states for medicinal use.

Despite the rising tide of legalization, many employers still regularly test for cannabis. The drug can impair a person’s decision-making and ability to concentrate in the short term, so being intoxicated can be dangerous for employees who drive, operate heavy machinery, or perform similar tasks.

However, current tests for cannabis suffer from drawbacks that make them ill-suited for rapid testing in the age of legalization. For example, the “gold-standard” tests work by detecting tetrahydrocannabinol (THC) — the main psychoactive component of cannabis — in blood or urine samples. But these tests are slow and can take several days to process.

THC also often lingers in the bloodstream for weeks in regular users and can still trigger positive test results long after the last use. Public safety officials and employers have difficulty telling whether a person who tested positive has used cannabis very recently (less than 12 hours ago) or sometime in the past few weeks.

“With marijuana becoming more accessible, it is important for public safety to have an objective way to tell whether a person is under its influence,” said Hakho Lee, associate professor at Harvard Medical School and senior author of the new study. “Find[ing] a parallel in roadside alcohol testing, we started to brainstorm a new sensor for on-site THC detection.”

Introducing EPOCH

Lee, Hojeong Yu, a postdoctoral researcher at Harvard Medical school and lead author of the new study, and colleagues designed and built a new rapid cannabis testing system they named EPOCH.

EPOCH uses an optical sensor to detect THC in saliva samples, where the compound’s presence correlates more closely with immediate cannabis use than it does when detected in blood or urine.

The sensor also includes features that allow the test to measure the amount of THC instead of only giving positive or negative results. The whole system can yield results within five minutes and can be docked with commercially available smartphones.

To measure their system’s accuracy, the research team performed a proof-of-concept test with 43 users of either inhaled cannabis or THC-infused jelly and 43 non-users. The scientists gathered and tested saliva samples from the users within 10 minutes of use.

The EPOCH system quickly detected THC in all of the users within five minutes, while the non-users didn’t show any significant differences in THC levels. Results from non-users weren’t affected by smoking cigarettes, drinking coffee, or other variables that might interfere with saliva test results.

Lee’s team continued to track THC levels in the cannabis users after the first test. They discovered that high THC concentrations in the test samples rapidly decreased in the hours after cannabis smoking. After six hours THC levels dropped to below 1 nanogram/milliliter, the detection guideline cutoff recommended by the European Driving Under the Influence of Drug, Alcohol and Medicines project.

“Combined with EPOCH’s speed and simplicity, the oral THC test has the potential to become a practical surveillance tool,” the study authors say.

Lee and Yu emphasize that more research is needed before the test can be deployed. They say further studies are necessary to define how quickly the oral THC concentrations decrease over time and to establish baseline differences between frequent and occasional cannabis users.

The researchers eventually plan to expand their test to detect other types of drugs, such as oxycodone and other synthetic opioids. “Since our device is a platform technology, we could readily detect different targets by switching capture [molecules],” said Lee.

Does CBD Show Up on a Drug Test?

With how popular CBD has gotten in recent years, more and more people incorporate the cannabinoid into their daily routines. But, this increased consumption has led to a lot of concern surrounding CBD and drug tests. Specifically, we all want to know: does CBD show up on a drug test?

To help ease your anxieties, Elevate Holistics is taking a close look into CBD, drug testing, and everything in between. Let’s get started.

Will CBD Oil Lead to a Positive Drug Test?

First and foremost, does CBD show up on drug tests? No: unless you are taking a CBD-specific drug test, employers are not looking to identify CBD consumption. They are looking for illicit substances such as THC, narcotics, or steroids. CBD is federally legal, and it doesn’t impair judgment or motor skills or artificially improve athletic performance, so there’s no reason to test for it.

On the other hand, residual cannabinoids in your CBD oil can lead to a failed drug test, and this is a big deal. A failed drug test can cost you your job and income; it can cause you to lose access to essential resources like education and welfare benefits, child custody, and prescriptions for pain medication.

Unfortunately, this happens because trace amounts of THC can stay in the body for weeks. This will ruin the drug test. As a result, employees who use CBD can accidentally fail a drug test if their product isn’t pure CBD. So, it isn’t the CBD compound itself that’s the problem — it is the residual THC.

How Does THC Get into Cannabis Oil?

Accidentally failing a drug test is costly, but how does it happen? Why is there THC in your CBD product? There aren’t a lot of explanations for that, but the two best reasons are:

Using A Product That Has THC

THC and CBD are from the same source – cannabis. As a result, CBD can contain up to 0.3% THC, and the more CBD you consume, the higher your chances of registering a positive THC drug test. According to Greg Gerdeman, Ph.D., chief science officer at Colorado’s United Cannabis, “If you’re liberal with your hemp CBD oil use, you could hypothetically test positive for THC.”

Product Mislabelling

You could do your due diligence and read the labels but still ingest more THC than you intended to because the label on the product is wrong. A study has shown that 70% of CBD products sold online contain more or less CBD than advertised. Marcel Bonn-Miller, Ph.D., an adjunct assistant professor of Psychology in Psychiatry and the lead author on the study, blames mislabelling on lack of adequate oversight.

“The big problem, with this being something that is not federally legal, is that the needed quality assurance oversight from the Food and Drug Administration is not available. There are currently no standards for producing, testing, or labeling these oils. When companies sell products without any oversite, there is no way to know what is actually in the bottle. It’s crazy to have less oversight and information about a product being widely used for medicinal purposes.”

Consider The Source Of Your CBD

Seeing as THC, not CBD, is the problem, pay attention to the source of CBD as this is an indicator of how much THC it contains. Legally, CBD can have up to 0.3% THC, but there are plenty of THC-free options. THC content depends on the option you choose, and they are:


Full-spectrum CBD oil, also known as “whole plant,” contains the most THC. During the extraction process, manufacturers try to retain the qualities of the hemp it is extracted from; this helps increase the potency of the CBD oil because the cannabinoids and terpenes in the hemp plant are present in the CBD oil. Also, it retains the ‘hempy’ taste and flavor. However, it has a significant caveat: CBD contains up to 0.3% THC and could hold more if the label is inaccurate. It’s best to avoid it if you don’t want to risk failing a drug test.

CBD Isolate

This is the opposite of full-spectrum; the process eliminates everything but the CBD during the extraction. The result is a high purity, flavorless CBD that is also less effective due to a lack of cannabinoids and terpenes. Many people prefer CBD isolate because it has no THC, and vendors who sell edibles sometimes like to use this.


This is a cross between full-spectrum and CBD isolate. The extraction process helps to completely get rid of THC while retaining the cannabinoids and terpenes present in the hemp plant. It offers the best of both worlds.

How Can You Pass A Drug Test For CBD?

As we’ve previously stated, employers and law enforcement are unlikely to carry out a CBD drug test; they have no reason to. However, if you’re worried about testing positive for THC, check out the detoxification guidelines we’ve explained here. They include dieting, exercise, drinking lots of water, and discontinuing use.

How Much CBD Will Make Me Fail A Drug Test?

Again, you may ask, does CBD show up on drug tests? Will it make me fail the test? No, CBD won’t make you fail a drug test; the culprit is THC. A little THC in your CBD won’t show up in a drug test, but if you consistently consume full-spectrum CBD, it could build up in your body and result in a positive test.

The amount of THC in your blood also depends on the amount consumed, the period, your metabolism, and other factors like hydration levels.

How Long Does CBD Stay In Your System?

CBD effects can last between 90 minutes and several hours, but the compound can stick around in your body long after the effects wear off. Your body converts CBD to a byproduct chemically known as CBD-OOH, and this byproduct can remain in your body for several days. Not to worry, though: no employer or law enforcement is testing for CBD-OOH.

How Long is CBD Detectable In Urine?

According to research, CBD has a half-life of two to five days; this means you’ll eliminate half the CBD in your system in that period. We’re not sure how long CBD stays in the body, but THC can last from 3 to 30 days. While employers and law enforcement are unlikely to do a CBD drug test, trace amounts of THC in your CBD oil can turn up a positive test.

How Long Is CBD Detectable In A Hair Follicle Test?

It is rare for employers and law enforcement to test for THC in hair, and for CBD, it is unheard of. However, if the CBD you consume over time contains trace amounts of THC, it can accumulate in your hair and stick around for up to three months.

Delta-8 and Drug Tests: Will You Pass? Or Will You Fail?

One of the most common questions from Eighty Six users is, “Will I fail a drug test on Delta-8 THC?” This is a totally valid question, especially with how recently the minor cannabinoid was legalized and classified as a hemp derivative.

Can you fail a drug test if you’re a Delta-8 user?

For both legal and employment matters, this is an especially important question and one we want to answer fully in our guide today. We’ll help you figure out if you’ll fail a drug test while using Delta-8, how long it stays in your system, and much more. First, let’s find out exactly how drug tests work and why testing for cannabis-derived products is so difficult to understand in the first place.

How Do Drug Tests Work?

Before we talk about Delta-8 THC and drug tests, it’s important to recognize how drug tests actually work, especially when it comes to THC. That starts with understanding how a drug test detects that someone has THC in their system. While employers and legal entities may have you think otherwise, drug tests are not the finely-tuned instruments they’re made out to be.

On the contrary, most labs in the nation are not yet advanced enough to be able to differentiate between the various cannabinoids from hemp or cannabis plants. What drug tests look for, instead, is the chemical signals in the body that THC has metabolized.

Unfortunately, the CBD, Delta-8, and Delta-9 THC that drug tests are actually searching for are almost molecularly identical. This can cause problems for those using CBD and Delta-8, causing a false positive when testing for Delta-9 THC because your body is releasing similar chemicals.

How Is Delta-8 Different from Delta-9?

We’ve explained the differences between Delta-8 and Delta-9 THC in a prior blog, so make sure you check that out before you read further. If you’re unfamiliar, Delta-9 THC, or tetrahydrocannabinol, is the full name of the THC found most abundantly in traditional cannabis products. Delta-8 is a minor cannabinoid that is less potent in comparison, though it is a cannabinoid that can still get you high.

Can Delta-8 THC Make You Fail a Drug Test?

Now, onto the meat and potatoes of the guide — will you fail a drug test on Delta-8 THC? Well, unfortunately, the answer is likely yes. As we’ve mentioned previously, drug tests aren’t perfect, and the room for error is wide. The chance of Delta-8 showing up on any generic drug test is not zero, simply put.

In fact, if you’re taking an at-home test, Delta-8 THC is even more likely to show up. This is because at-home testing is typically the least advanced of all drug tests. These types of tests are not able to differentiate between cannabinoids, which is why you’ll likely pop off hot from even nonintoxicating cannabinoids like CBD, as well.

Whether you’re consuming Delta-9 THC from your local dispensary or Delta-8 online, the cannabinoids metabolize into the same THC metabolites in your body. That means consuming any amount of any THC can cause you to fail a test.

The legal limit is 0.3% Delta-9 THC in a CBD or hemp-derived product. You can, however, be taking more than the recommended daily serving sizes, which means the 0.3% THC has the ability to build up in your system. There is a real possibility that your Delta-8 use will show up on a drug test, depending on how often you consume it.

Yes, you can fail a drug test on Delta-8 THC, but fortunately, there are still options. Keep reading below to see how to pass a drug test even after you’ve consumed Delta-8.

How Long Does Delta-8 Stay in Your System?

While it’s less potent than Delta-9, Delta-8 is still THC, which means it lingers in your body just like any other substance would. Even for first-time users, THC has the potential to stay in your urine for 4 to 8 days. That’s one reason to learn about Delta-8 THC and drug tests before you get started.

Heavy Delta-8 users should expect to stay positive on a drug test for 30 to 60 days — sometimes even longer! This varies from person to person, namely due to other factors that determine how long THC stays in your system. Since THC clings to fat cells, how active you are and your current lifestyle will play a role in how long this cannabinoid will remain in your body. Other variables include cannabis tolerance, length of use, and more.

Can You Pass a Drug Test After Using Delta-8?

Okay, so you’ve taken Delta-8 THC and a drug test is coming up. There’s no need to panic! Delta-8 is a legal, hemp-derived product, but THC showing up on a test is still hard to explain. Luckily, there are a variety of methods out there to help you pass the test.

How you’re going to pass this test will mostly come down to how long you have to prepare. If you know about the date in advance, your chances of passing are much better.

Wait It Out

The first, and most obvious option, is to simply avoid Delta-8 when your drug test date approaches. Depending on your tolerance level and weight, among other things, the THC may stay in your system for upwards of 2 months, so you’ll want to plan around that accordingly if abstinence is going to be your method.

Exercise and Stay Hydrated

Then, there’s the second method of passing a drug test after using Delta-8 THC. Remember when we said THC clings to fat cells? It’s time to work up a sweat! Burning fat, losing weight, and staying hydrated in the weeks or days leading up to your drug test are some ways to increase your pass rate.

The Morning of the Drug Test

The morning of the drug test, make sure you pee when you wake up to clear out the THC metabolites that have built up in your sleep. Drink some diuretics, like coffee or cranberry juice.

A Couple Hours Before the Test

This is the time to take some B12 vitamins before chugging lots and lots of water! Crunch time means getting as hydrated as possible. Now, this may cause the test to be invalid because you’re too hydrated, but this will give you a chance to retake it at a later date. If you’re stressed about not passing a drug test because of Delta-8 THC, this is a golden opportunity to have a little longer to take the test.

Getting Drug Tested as a Delta-8 User

It’s not the end of the world to have Delta-8 in your system and be required to take a drug test. There are always options around failing that test, especially when it comes to this special form of THC. We hope this was informative in answering your questions about Delta-8 THC when it comes to drug testing.
