CBD and First Responder Drug Testing

CBD is safe for drug testing. But only if it’s verified 0.000% THC.

Let’s start off by addressing the most important part of this article: Pure CBD does not cause a failed drug test.


Now we have that all cleared up, let’s talk about why the words “pure CBD” are so important for first responders to understand.


CBD is a molecule found in the hemp plant, which is considered a cannabinoid. THC is also a cannabinoid and there are plenty more found in the hemp plant (like CBG, CBN, CBC). Urinalysis drug tests look for the cannabinoid THC and its metabolites. They do not look for CBD. So, if you’re taking CBD isolate which is 0.000% THC then you won’t have to worry about failing a drug test.

Are all CBD products “Pure” CBD?


Pure CBD isolate has to be manufactured to have all the other compounds naturally found in the hemp plant filtered out, leaving behind the CBD molecule and nothing else. No THC, no CBN, and no other terpenes

CBD can be made to contain all of the naturally-occurring ingredients found in the hemp plant. There is a spectrum of compounds that can be found and if you’re taking CBD that’s made from the entire hemp plant, it’s called full spectrum CBD. This is CBD with small amounts of THC in it. The hemp plant naturally produces up to 0.3% THC and that’s now become the legal limit for THC in hemp and CBD products.


So, if you’re taking full spectrum CBD, you’re also taking trace amounts of THC with it and this could lead to a failed drug test. This is why it’s so important to verify if your CBD products have 0.000% THC in them.

How drug testing works

If you work for a public safety agency or really anywhere that requires you to take random drug tests, you may know the process already. But, in case you don’t, this is how it goes:

Preliminary test

First you have to go to a preliminary test. A preliminary test is fast and cheap. You’re called into a drug testing office, it could be a urgent care clinic, or a lab testing facility (like Labcorp or something similar). The tech administering the test has you produce a urine sample that is placed into two containers where they’re labeled and sealed. These containers are then sent off to be tested for all of the substances your agency looks for in your urine. The only equipment this uses is a dipstick. If there are any of the drugs being tested for present in the urine, it will change color.

A typical DOT standard urinalysis (What most public safety agencies use) looks for 11 drugs:

  • Marijuana
  • Cocaine
  • Amphetamine
  • Methamphetamine
  • MDMA
  • MDEA
  • MDA
  • Opiates/Morphine
  • Heroin
  • Codeine
  • Phencyclidine

By “Marijuana” this drug test is referring specifically to THC and its metabolites. The cutoff range for THC to cause a failed drug test is 50 nanograms (1 million nanograms is 1 milligram). CBD is not part of DOT drug testing or any standard drug testing as of 2020.

If any of these drugs come up positive, meaning you’ve failed the preliminary drug test, you won’t know about it yet. Instead, just to be sure this isn’t a false positive, the urine is sent to another laboratory with specialized equipment used to detect and quantify specific amounts of molecules present in your urine. This second test is called a confirmatory test.

Confirmatory Test

A confirmatory test does just that. Since the urinalysis can produce false positives, they use this expensive equipment only when they have a failed preliminary test. This test looks for as little as 15 nanograms of THC in your urine. They’ll use either HPLC (high performance liquid chromotography) or GC-MS (gas spectrometry mass chromatography).HPLC machine used for drug testing CBD for first responders

Big words. But, basically all it means is they use equipment to see exactly what chemicals are in your urine “under a microscope” instead of just looking at a dipstick from your urine. It’s much more scientific and it can prove/disprove your preliminary test.


Any confirmatory test that shows there are drugs present will now officially be called a failed drug test.

The Medical Resource Officer (MRO)

Once you have a failed drug test, your employer still doesn’t get notified. First, the Medical Resource Officer will call you and ask if you have a prescription for the drug you failed on or ask a reason why you may have failed this drug test.

For example: if you test positive for amphetamines but have a prescription for adderall, then they’ll ask you to provide the script and then that’s the end of the matter.

If you cannot provide a valid reason for failing a drug test or show a prescription, then they notify your employer.

It seems complicated but it’s really only a few steps.

1- A cheap dipstick for a preliminary test (that CBD doesn’t show up on)

2- An expensive scientific confirmatory test

3- A phone call asking verifying questions from the MRO

First Responder unions and local lawsa contract for first responders and CBD

So, where does the union and local/state law come into play? Well, first off CBD with < 0.3% THC is legal in all 50 states. This is why you need to be careful in selecting a CBD product.

Just because it’s legal doesn’t mean it won’t cause a failed drug test. Poppy seed bagels are legal but they can cause a failed drug test as well. As a first responder, you have to verify there is 0.000% THC in your CBD products. There are no laws that restrict anyone, let alone first responders, from using hemp products and their extracts which includes CBD.

Your union contract can stipulate whether you’re specifically banned from CBD use. Most contracts just state that marijuana is tested for and that’s it. In these cases, you’re authorized to use CBD since the federal government clearly defines hemp as a different plant than marijuana. CBD cannot legally be made from marijuana, it is only made from hemp unless you’re purchasing it from a dispensary using your medical marijuana card.

Occasionally, we’ve seen where unions or city policies have specified CBD and/or hemp products to be restricted from use. In these cases, it’s very clear that you’re not authorized to consume CBD products unfortunately.

First Responder Drug Testing And CBD: The Bottom Line

In summary, let’s just highlight the important stuff:

  • If you’re taking CBD that has been verified to contain 0.000% THC then you’re safe from failing a drug test. These are called CBD isolate products.
  • Full Spectrum CBD contains up to 0.3% THC and can lead to a failed drug test
  • Full Spectrum is legal and it’s up to you as a first responder to verify you have 0.000% THC in your CBD with lab tests.
  • CBD is not looked for or detectable in your standard urinalysis drug tests.
  • CBD is legal in all 50 states but your union can specifically restrict its use, so check your contract.

a short bio of Jon Vought

CBD is legal for everyone. There are no laws that restrict CBD use on a federal level. However, your union or agency policy can specifically restrict CBD use if it’s in your contract. Most agencies do not specifically restrict CBD, they restrict marijuana.

A standard urinalysis does not look for CBD, it looks for THC and its metabolites. THC is what causes intoxication and its metabolites are what a standard urinalysis detects.

If it can be verified to have 0.000% THC, then yes. Full spectrum CBD is legal but it contains THC (in small amounts) and can lead to a failed drug test.
