In theory, CBD is not supposed to show up on drug tests. However, since most CBD products are typically classified as a supplement, there are no regulations regarding safety and purity. As a result, contamination with CBD can occur, and this can reveal itself in a drug test depending on the test’s cut-off level and other factors.
CBD is more likely to show up on a drug test if it’s derived from marijuana rather than hemp. According to law, the latter must contain less than 0.3% THC to be classified as hemp, but regular or daily ingestion of high doses of it can still result in an accumulation of THC.
In most cases, cannabis origination in broad-spectrum CBD is less likely to contain THC contaminants. The reason for this is that THC is absent in broad-spectrum CBD, unlike with full-spectrum CBD, which has all the compounds that occur naturally in the plant. CBD isolate, also known as pure CBD, usually comes from hemp. This means that it doesn’t have traces of THC.
If you’re scheduled for a drug test and want to pass with flying colors, avoid taking CBD. Or, if you take it legally in your state, make sure to declare it. This is because your sample may be contaminated with THC unless you purchase it from a reputable supplier who can guarantee that it’s THC free.
The Amount Of THC That Needs To Be Present To Cause A Positive Drug Test
The truth is that it’s difficult to say just how much THC needs to be present to cause a positive result on a drug test. It depends on several factors, including drug and patient-specific variables and the cut-off value of the test.
The following are some variables that affect the amount of time THC and its metabolites can remain detectable in urine and other kinds of biological samples..
- Presence of other interacting drugs.
- The amount used and the method of ingestion.
- The last time an individual ingested.
- The rate of cannabis use (the half-life known for THC is 1.3 days for individuals who are not frequent users and 5 to 13 days for those who are)
Several other factors can also affect a drug test result, such as urine concentration, urine PH, body mass, and medical issues like liver or kidney disease.
Drug testing may require various biological samples, like urine, blood, hair, or saliva. However, urine drug testing is the most common method, especially when it comes to workplace testing. This is because it isn’t invasive, and samples are usually easy to collect.
Drug tests look for the parent drug or at least one of its metabolites, and in some cases, both. Concentrations of drugs in the urine are typically higher than in the blood and remain present for more extended periods. This also applies to states that have medical cannabis. So if you think a drug test is coming up for you, it’s ideal you stop taking your CBD for some time before, to avoid any unwanted hasse.
