If you take CBD oil, there are measures you can take to try to prevent failing a drug test.
The conclusion is that it’s still theoretically possible for traces of THC metabolites to be present in the stomach acid in the instance where “less-purified CBD productions” are ingested.
CBD oil extracted from hemp is not supposed to have any more than .3 percent of THC. However, it’s not uncommon for sellers to mislabel their products as THC-free hemp when in reality, it’s a low-quality oil extracted from marijuana, which does contain THC.
How to Avoid a Positive CBD Drug Test
Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the cannabis genus. Both marijuana and hemp can be described as cannabis plants; however, it is important to note that they are still two separate plants.
Most CBD products are made from hemp, not marijuana.
A more likely secondhand exposure scenario is a positive marijuana hair test, resulting from direct contact with marijuana paraphernalia or from another person having THC on their hands.
What are the odds that CBD oil users will test positive when subjected to illicit drug screenings, and what can be done to prevent it?
It is difficult to say how much THC needs to be present to cause a positive drug test because this depends on several drug and patient-specific variables, and also the cutoff value for the test.
Despite the widespread use of urine drug tests, there appears to be some inconsistency in the interpretation of test results. Considering the significant consequences a false-positive result can have (such as loss of job or imprisonment), this is somewhat surprising. But it is also something to be aware of, because it may mean that what is considered a pass (a negative result) in some circumstances may be considered a fail (a positive result) in others.
Confirmatory tests (Drug of Abuse Panel tests) use gas chromatography/mass spectrometry to identify specific molecular structures and to quantify the amount of drug or a substance present in the sample. These are more accurate than screening tests, but are also more costly and time-consuming and are usually reserved for situations that have significant legal, academic, forensic, or employment sequelae. These recognize cannabinoids rather than metabolites so should be able to distinguish CBD from THC.
Federal workplace cutoff values for marijuana metabolites are 50 ng/mL for immunoassay screening tests (one ng is a billionth of a gram). In a confirmatory test, a metabolite of marijuana is measured, called delta-9-tetrahydrocannabinol-9-carboxylic acid, and a positive test result is above 15 ng/mL. However, this can vary depending on the variables listed above and should not be relied upon to ensure a drug-free result.
An estimate of the length of time marijuana (THC) is detectable in urine is:
