Does CBD Show On A Drug Test?

CBD, a cannabinoid derived from the same plant as maraijuana, has gained a lot of attention recently for its health benefits. However, many people wonder if CBD shows up on drug tests. 

Generally CBD does not show up on drug tests, as it is not a chemical that is typically tested for. But CBD can show up as a false-positive for maraijuana if the CBD you’re taking contains THC. This article will go into detail about how drug tests work, how long CBD stays in your system, and how to ensure CBD doesn’t show up on a drug test.

How Do Drug Tests Work?

Drug testing is done through the examination of a person’s body fluids, such as blood and urine. The test will register the presence of drugs or their metabolites (compounds that are produced when your body breaks down the drug) in these fluids to determine if an individual has recently used any of the drugs being tested for. Drug tests can show what kind of substance was taken, and whether it has been consumed recently. They are commonly used by law enforcement and medical personnel to determine if a person is under the influence of drugs or has consumed them in the recent past.

There are several types of drug tests:

– Urine test, which now offer a newer type of urinalysis that can detect THC-COOH better than older methods

– Saliva based detection using mouth swabs

– Sweat patches on the skin that can be used to measure excreted chemicals

Most drug tests look for THC, more formally known as tetrahydrocannabinol. TCH is most commonly found in marijuana and is responsible for producing the feeling of being high. CBD only contains trace amounts of THC, with most CBD containing none at all. The legal standard in most states is that CBD oil must contain less than 0.03% THC.

Will CBD Show Up On A Drug Test?

CBD is not considered an intoxicating substance because it doesn’t have psychoactive properties (it does not act on the brain and alter your state of mind). Therefore, CBD will not show up in a urine drug screen. This is because drug tests are targeted to look for illegal narcotics such as opiates, amphetamines, and other substances that cause intoxication. Marijuana drug tests are designed to detect the presence of THC, which means a pure CBD product will not produce a positive result. 

CBD products like oil tinctures are considered safe because they contain low amounts of THC (less than 0.03%), but it may still be detectable at higher doses depending on how often someone uses it, their metabolism rate, and the off chance that the batch they of CBD they are taking, is not as pure as the label states.

If you are still concerned about testing positive on a drug test, the best thing to do is abstain from using CBD for a few weeks before the test. If this isn’t possible, breathing clean air and exercising will help reduce CBD levels in your system. The less you have circulating in your bloodstream and lungs, the lower chance there is of testing positive. In addition, stay hydrated as that can flush out toxins more efficiently.

How Long Will CBD Stay In My System?

CBD will stay in your system for about three to five days after your last dosage. But this can vary from person to person, depending on how often they use CBD and the dose. There are reports of some individuals requiring multiple weeks before their system has fully flushed out all the CBD.


CBD does not show up on most drug tests, so typically you don’t have to be worried about getting a false-positive. But if you are feeling concerned, then the best thing to do is fully stop your CBD consumption at least a week prior to when your drug test is scheduled.
