CBD Drug Test
CBD Aug 12

It’s summer 2022. The FBI just found dozens of classified documents in Trump’s Mar-a-Lago home, the war in Ukraine is raging, and it’s hot as hell out. But hey, hemp-derived CBD is legal now, so we can get some relief, right?

If you’re interested in trying CBD or have already jumped into the pool of anxiety relief fully clothed, we’ve got some info that might be useful. If you get drug tested on the regular, we’d imagine you’ve asked yourself, “Does CBD show up on a drug test?”. The answer to this is a little more complicated than you think.

While CBD on its own isn’t detected by drug tests, certain hemp-derived CBD products might cause you to fail a drug screening. Let’s get into it.


In short, no. CBD on its own will not show up on a drug test. However, many CBD products contain trace amounts of delta-9-tetrahydrocannabinol (THC), marijuana’s main active ingredient, which is what drug tests for cannabis aim to detect.

This means that in rare cases, using CBD might lead to a positive drug test. It all depends on the product’s quality and composition.


According to a 2020 article, urine drug tests usually target the following substances:

  • alcohol
  • amphetamines
  • benzodiazepines
  • opiates
  • cocaine
  • cannabis

The urine test is the most common test for cannabis. Also known as an “immunoassay test,” urine testing uses antibodies designed to latch on to specific drugs or their metabolites — in this case, the presence of THC and its metabolites. When these metabolites show up they produce a signal that shows the test as “positive”.

Because cannabinoids (THC, CBD, etc) are fat soluble, tests may detect weed for 3 days after a single use and more than 30 days after heavy use.


CBD is derived either from hemp, a specific strain of the Cannabis Sativa plant, or from THC-containing cannabis (aka marijuana). Hemp-derived CBD should contain no more than 0.3% THC, per the Federal Drug Administration (FDA), but product testing reveals it can sometimes exceed this federally legal limit.

To make things more confusing and trivial, the source of CBD isn’t the only factor. Harvesting and refinement methods can also change the chemical makeup of your CBD oil.

CBD extracts are typically broken down in the following categories:

  1. Full Spectrum CBD: Full-spectrum CBD contains several components of the cannabis plant, including trace amounts of tetrahydrocannabinol (THC). Federally legal full-spectrum products will always have less than 0.3 percent THC. In states where cannabis is fully legal, you may also be able to find full-spectrum products with higher THC levels.
    • We believe in the power of the full plant at flowerz™, and full-spectrum has the most powerful effects. Most flowerz products carry up to the federally legal limit of 0.3% THC, alongside delta-8, delta-10, and THCV — all of which can be detected by a drug test. If you want to avoid failing a drug test, stick with CBD isolate and broad-spectrum extracts (the latter is more efficacious).
  2. Broad Spectrum CBD: This type of CBD does not contain THC. It does contain other components of the cannabis plant, though, so it won’t be 100 percent CBD. Consider it the middle child of the three CBD choices.
  3. CBD Isolate: CBD isolate extracts carry only CBD and no other plant compounds. This won’t result in a failed drug test unless the extract wrongfully carries THC without you knowing.


According to Mayo Clinic Info, federal workplace drug testing cut-off values were established to avoid the possibility that trace amounts of THC would trigger a positive test. In other words, passing a drug test doesn’t mean that there isn’t any THC present in your system.

In urine, THC must be present at a concentration of 50 nanograms per milliliter (ng/mL) to trigger a positive test. (A nanogram is approximately one billionth of a gram.) Detection windows vary a lot according to dose and frequency of use.

In general, THC metabolites are detectable in urine for approximately 3 to 15 days after use. But heavier, more frequent cannabis use can lead to longer detection windows — more than 30 days, in some cases.

In Layman’s Terms:

How long does THC stay in your system?
  • Urine Test: 3-30 days (daily consumer)
  • Blood Test: 45-60 days
  • Hair Test: 90-120 days (daily consumer)
  • Saliva Test: 1-7 days (daily consumer)
What factors determine the time window for THC still being in your body?
  • Body Mass (BMI)
  • Metabolism
  • Levels of THC in your body


It’s hard to detox THC from your body. If anyone tells you differently, they’re either lying, misinformed, or trying to sell you a bogus product. CBD, THC, and their metabolites store securely in your fatty tissue. No detox juice, tea, or “special solution” can enter these fat cells and remove them.

When it comes to cannabis, detoxing is a process that can take some time. The more days or even weeks you have to detox the better. Unfortunately, not everyone has ample amounts of time. To help speed up your body’s detoxification process, there are a number of different options, just note that some work better than others.

  1. Natural Cleanse: Most people can complete natural cleanses in 30-60 days. It requires you to change your lifestyle as well as your eating habits to make sure that your body is eliminating the THC that is stored in your system.
  2. Detox Drinks: Same-day detox drinks can be helpful for stimulating your body’s natural detoxification process; however, they can also be helpful in creating a window in which you can test clean. Just be warned, some detox products can strip urine of the indicators that testers are looking for to ensure the samples are genuine.
  3. Detox Kits: A quality detox kit will ensure that THC is absent from your urine sample without stripping it of other indicators. As opposed to same-day detox drinks that will ensure your urine is clean for a few hours, a detox kit will permanently flush your system of traceable THC levels. Generally ranging between five and ten days, detox kits use herbal supplements to assist your body’s natural detoxification process.
  4. Home Remedies: Many home remedies, like ingesting cranberry juice, tea, lemon juice, or apple cider vinegar, don’t detox so much as mask THC in your urine (or blood) so that it doesn’t register as strongly as it would normally.
  5. Synthetic Urine: Red flag. When it comes to synthetic urine, not having THC is the easy part. Labs are so sophisticated at this point that passing off a non-human source is almost impossible.

Googling “THC detox” results in an overwhelming cacophony of detox methods  — everything from adding bleach to your urine sample (don’t do this) to taking large doses of vitamins to drinking copious amounts of liquid for weeks on end. Many of these methods, parroted by non-experts, are not backed by science at all and can be risky for several reasons.


Yes, CBD may yield a positive result on a drug test, but it shouldn’t show up on a routine drug test. Keep in mind that the industry isn’t consistently regulated, and it’s hard to know what you’re getting when you purchase a CBD product. There are certain things you can do to pick the right product and make sure you’re buying CBD that has the lowest amount of THC possible, but there’s no guarantee that the labeling is accurate due to the lack of regulation of CBD products.
