Smoking or vaping CBD flower is one of the best ways to enjoy the benefits of CBD. Many people who are new to hemp flower, however, wonder if you can fail a drug test from smoking CBD.
Secret Nature products contain less than 0.3% THC, and drug screenings aren’t designed to test for CBD. In this guide, we'll cover all your CBD drug testing questions, and we'll finish by telling you what to expect from CBD drug screening in the future.
Can you fail a drug test for CBD?
The short answer is “no” since drug tests are usually not designed to detect the presence of CBD. Some CBD products contain THC, however, which has the potential to cause a positive drug test reading even when only present in small concentrations. Types of CBD that contain up to 0.3% THC are usually referenced as “full-spectrum” while products with undetectable levels of THC are called “broad-spectrum” or “isolate.”
Is there a drug test for CBD?
If you are being tested for cannabis or marijuana at work or for another reason, it is very unlikely that your employer is testing for CBD. The majority of testing parties are interested if you’re using THC products, not hemp, and the overwhelming majority of cannabis drug tests only test for THC, not CBD.
However, there are some drug tests in existence that test for CBD. These tests aren’t widely used, though, and make up less than 1% of the total cannabis tests used per year.
Can using CBD make you fail a drug test?
There’s always a potential — however slim — that CBD might make you fail a drug test since every CBD product contains some trace amount of THC. That’s the case whether it's full-spectrum CBD with up to 0.3% THC or purified CBD isolate with just a few THC molecules kicking around.
From there, it's all a matter of math. Even if you consumed nothing more than a huge amount of isolate CBD with less than <0.0001% THC, it’s technically possible to test positive for “marijuana.” Full-spectrum CBD products can contain up to 0.3% THC, but it’s still necessary to consume an extraordinary quantity to yield a false positive.
If you were to consume an enormous amount of Secret Nature products (an ounce of flower per day for two weeks for the sake of argument), it's possible enough THC would accumulate in your system to make you fail a drug test. You’re encouraged to fire up your lighter or vape and place a big order.
How much CBD will make me fail a drug test?
No amount of CBD will make you test positive for THC since these substances are clearly distinct from each other on a chemical level. Most CBD products, however, contain trace amounts of THC, making it possible to test positive for cannabis or “marijuana” under certain circumstances.
That’s why third-party lab testing is so important. Secret Nature offers verifiable, third-party lab reports with every batch of products we produce, which you can use to determine the exact amount of THC you’re ingesting in our full-spectrum hemp products.
How long is CBD detectable in urine?
Like most cannabis compounds, CBD is fat-soluble. Water-soluble substances pass through your body quickly, but fat-soluble substances absorb into your fatty tissues where organs like the liver and kidneys process them out slowly.
If drug screenings tested for CBD, it's likely this cannabinoid would remain detectable in your system for around 30 days. That's how long THC stays in your system as well, and approximately 30 days is the standard excretion time for fat-soluble substances.
With the exact percentages of CBD and THC in the product and the THC detection threshold of the test, it’s possible to calculate how much of a particular CBD product you can use before you test positive for THC. Just keep the following in mind if you're worried about failing your drug test due to CBD:
- Cannabinoids only last about 30 days in the body,
- Will 0.3% THC show up on a drug test? CBD products that are verified to have less than 0.3% THC by an independent lab can only make you fail your drug test when you consume them in very high quantities.
Will Hemp Lotion Show Up On A Drug Test?
Just as with other CBD products, the potential to fail a drug test after using a hemp topical certainly exists. To understand how topical and oral CBD might affect drug testing differently, we need to look at the differences between the oral and transdermal CBD administration routes.
When you ingest CBD orally, it passes through your liver before entering your bloodstream. This option provides a full-body effect, but the intensity is limited by your digestive system’s filtration mechanisms, and you can’t pinpoint problem areas.
Topical application of CBD, on the other hand, addresses specific areas without providing a notable system-wide effect. CBD can be formulated into both water-based and oil-based topical products, which has resulted in an extremely diverse cannabidiol topical market.
The major bulk of the cannabinoids you apply topically remain in the area they’re applied. A small percentage enter your bloodstream, but it’s a fact that topical administration delivers far fewer cannabinoids throughout your body than oral ingestion. So, failing a drug test after using a CBD topical is much less likely.
Does Secret Nature provide lab tests?
Reviewing lab reports is the best way to ensure your hemp flower won't make you fail a drug test. At Secret Nature, we provide fully transparent and detailed lab reports from a select group of widely respected, independent cannabis testing facilities.
In addition to testing for each of the major cannabinoids, we also test the terpene profile of each Secret Nature product. Terpenes are almost as important as cannabinoids, and you deserve to know exactly how much myrcene, caryophyllene, and limonene are in your vape cartridge or hemp flower.
Will there be drug tests for CBD?
Given the direction cannabis laws are shifting, it’s extremely unlikely you'll never have to worry about "testing positive" for CBD. Employers will remain free to fire workers for cannabis use for the foreseeable future, but state and federal laws are changing. Even though THC might inevitably prove itself inextricable from CBD, THC already testing isn’t a priority for many employers.
FAQ — CBD drug test
Anything else we can answer about how CBD might impact a drug test?
1. Will CBD ruin a drug test?
If you consider a drug test to be ruined when it shows a positive result for THC, then the chances of CBD “ruining” a drug test are very slim. All CBD products contain trace amounts of THC, and some contain more THC than others. If you’re concerned that testing positive for THC could impact your job, clear your CBD use with the party requesting the test first.
2. Will CBD show on a probation drug test?
CBD is very unlikely to be a problem with your probation court. In some states where recreational cannabis is legal, probation drug tests no longer test for THC, and as a non-intoxicating substance that drug screenings don’t even test for, nobody will care if you use CBD even if you’re a parolee. Using full-spectrum CBD products in states where THC remains illegal, however, could land you in hot water with your probation officer due to the small chance of THC accumulation reaching the designated testing threshold.
3. Can you pass a DOT drug test on CBD oil?
The United States Department of Transportation (DoT) enacted a very strict zero-THC policy for its employees in February 2020. Per this policy, “CBD use is not a legitimate medical explanation for a laboratory-confirmed marijuana positive result.”
As a DOT employee, a positive THC result may still result in termination even if you claim you “only used a CBD product.” Proceed with caution.
4. Will full-spectrum CBD oil make me fail a drug test?
Out of all the different types of CBD, full-spectrum CBD is the most likely to cause a false positive on a drug test for THC. That’s because full-spectrum hemp products might contain up to 0.3% THC, which is allowed by the 2018 Farm Bill.
As you can imagine, consuming enough products containing 0.3% THC can make you fail a drug test. Even though it’s in concentrations so small that a single CBD flower session could never make you high, those tiny amounts of THC can accumulate in your fatty tissues over time to make it seem like you’ve used more THC than you have.
5. Will CBD make me fail a hair drug test?
A hair drug test, also known as a follicle drug test, provides detailed data on the substances you’ve used that goes back much further than urine testing (urinalysis). If THC doesn’t show up in urinalysis since it’s been too long since you’ve used it, this cannabinoid might nonetheless show up in a hair drug test.
If you use a lot of full-spectrum CBD products that contain up to 0.3% THC, it’s certainly possible that this THC might show up in a hair follicle test. One thing follicle tests are great about, though, is determining exact concentrations of substances. So, it should be readily apparent that the amount of THC you consumed was too small to have been from a cannabis product, proving you used hemp instead.
6. Does LabCorp test for CBD?
With hundreds of offices nationwide, LabCorp is one of America’s biggest drug testing providers. LabCorp does offer tests that detect both CBD and THC that are primarily designed to be used in workplace settings.
Testing for CBD is incredibly rare, though, because most employers don’t see any reason to restrict the use of a non-intoxicating substance. With the lines between hemp and cannabis blurring daily, though, making sure your CBD products don’t contain enough THC to get you high is an increasing priority.
7. Can you fail a drug test from CBG?
The cannabinoid CBG (cannabigerol) is not a controlled substance, and to our knowledge, there are no lab tests that specifically detect CBG. Many CBG hemp products, though, are full-spectrum, which means they contain up to 0.3% THC.
As a result, the same potential issues with CBD also apply to CBG. If you consume too many CBG-rich hemp products that also contain trace amounts of THC, you might test positive for THC in urinalysis.
8. Will vaping CBD show up in a drug test?
Vaping CBD is one of the most potent ways to use this cannabinoid, and many CBD vape products contain trace amounts of THC. As a result, it is certainly possible, though very unlikely, that you could fail a drug test for THC after using CBD vape products.
If you want to avoid testing positive for THC, consider using CBD vapes that are advertised as “isolate” or “broad-spectrum.” Without the terpenes present in full-spectrum hemp extract, though, CBD might become less effective.
9. Does CBD show up on a drug test?
Just to be abundantly clear, CBD will never show up on a drug test since tests aren’t calibrated to detect it, but they might detect the trace amounts of THC present in most CBD products. For a false positive for THC to take place, though, you’d need to be a habitual hemp user consuming large quantities of full-spectrum CBD products every day.
