People who use CBD for medical or recreational purposes are concerned about the legality of this wonderful compound. And if you are here, then you want to know if CBD will show up on a drug test, so let’s find out if it will or will not show up on a drug test.

For starters, there are slim chances of a drug test after you get CBD in your system; this is because almost all of the CBD products are categorically supplements.

Talking of the other possibility, conceptually, it will not show up on a drug test. But it is accurate until the CBD you use is from a trusted source and does not contain any THC (tetrahydrocannabinol) trace amounts more than 0.3%. THC is the main active component of marijuana. Your CBD oil is prone to contain THC if it’s mother source is marijuana instead of hemp.

The CBD that comes from hemp, on strict laws, contains less than 0.3% THC; thus, it will not show up on a drug test if you regulate the dosage amount. Theoretically, doses of the CBD can cause THC to amass in your system, and this can show up on a cutting-edge drug test. However, practically, this is not possible, as you’ll have to consume CBD in a very large dose in a very short period.

On the other hand, the CBD coming from marijuana has no check over its THC content and is more likely to show up even on a simple drug test.

So if you want to pass a drug test with CBD in your system, you need to make sure that your CBD comes from clean sources like CBD oil in Florida and has a permissible amount of THC in it, i.e., less than 0.3%.

How much THC will cause a positive drug test?

There are several measures to decide on the positivity of THC in the body system, and all these measures are different for every individual – person or drug. With this uncertainty, it becomes difficult to set up a standard amount of THC that’ll show up on a drug test.

The tests for the presence of THC in the offending amount are run on various biological specimens like blood, urine, saliva, hair follicles, and nails.

Here’s a list of things that may or may not affect the results of a drug test on the CBD in your system:

  • Repetition rate – It’s different for everyone. If someone frequently uses CBD with high THC or intakes marijuana regularly, then the THC can stay in their system from 5 days to 13 days, depending upon the intake quantity. In parallel, for an infrequent user, the half-life of THC in the body is only 1 to 1.5 days, meaning that there won’t be any trace after 4 days of intake.
  • Quantity of CBD with THC traces in consumption.
  • Time of last ingestion – It will also notably affect the test results. As we know, the full life of THC is 4 days in occasional users. If the test is done on the second day of ingestion, then the test will be a hundred percent positive.
  • Any renal disease like kidney disorders or other body malfunctions could also temper the results of a drug test.
  • Urine’s pH will also affect the THC traces in the body. Reason for this is the fact that CBD changes into THC when it comes in contact with acids. So more acidic urine will account for dominant traces of THC in the results.

Although there are several drug tests present in the medical world, testing by urine sample is the most common one because of the ease it poses. Here is some intel that you should have to have the upper hand:

  • As per research, the threshold value of THC in the body for a negative result is 50 nanograms per milliliter [50 ng.mL-1]. That means, if you have more than 50 nanograms of THC in 1 milliliter of your urine, you will screen positive on the drug test. Just so that you know, a nanogram is a billionth of a gram.
  • As per the above information, the THC content varies a lot in the human body. Depending upon the frequency of use, here’s how long it can stay in your body:
  • One-time use – 3 to 4 days.
  • Middle-of-the-road-use – up to 7 days.
  • Long-standing use – from 15 to 30 days.

Other types of drug tests for THC

  • Blood test – They are very much rare for testing CBD or THC in one’s body. The reason being, the THC traces in your CBD stay only for five hours in the bloodstream. These tests are more common to declare someone’s impairment, for example, driving after the intake of CBD with THC infusion.
  • Saliva test – This method of testing for CBD is also an uncommon one. Although the THC trails are only visible for a small window of 72- hours in the oral canal, yet research suggests 4ng/mL as the cutoff for drug tests through the saliva of a person under the influence.
  • Hair test – As futuristic as it sounds, hair testing for tracing THC is a thing. But it is sporadic, and only some private organizations offer it. Surprisingly, THC metabolites stay up to 90 days in human hair.

How to be on the safe side.

You must be wondering if THC is traceable in the body, then what should you use CBD without leaving a trail, well the answer is simple – make sure your product doesn’t have THC.

  • Thoroughly read the description.

Most CBD products that have THC in them mention it clearly that they contain marijuana extracts. Marijuana extracts carry a considerable level of THC, so opt-out of these products. Use CBD products like CBD oil in Florida that have hemp extract instead of marijuana, and the CBD will be intractable.

  • Know your seller.

Always buy from authentic and reliable sellers for your CBD. Please don’t rely on street side sources for your CBD does, as their products may contain THC at high levels. Always prefer buying your CBD from trustworthy sellers who are open about sharing the ingredients in their product. With the right information, you can enjoy your delicious CBD gummies that work for your condition without having to worry about authenticity.

In addition, you should also try to find the legitimacy of your seller. Make sure your seller has third-party certifications about their CBD products. The third-party certifications help the products stand out from the crowd of so many generic and unauthentic CBD products. Third-party lab tests of a CBD product provide one hundred percent impartial results, therefore making them safe to consume.

Bottom line

You don’t need to worry if you are put on a test for CBD in your system, as it will never show up on a drug test. Even though being certain about the whereabouts of your CBD’s sources won’t hurt, as the industry is not under constant government control.

Purchasing CBD with hemp extract and CBD isolates are the only way for you to use CBD anonymously.
