Does CBD Show Up On A Drug Test?

Navigating CBD and Drug Tests:

In the midst of cannabidiol’s (CBD) widespread popularity, there remains a considerable amount of confusion, particularly concerning whether it registers on a drug test.

Both CBD and delta-9 tetrahydrocannabinol (THC) are cannabinoids, representing active constituents derived from the cannabis sativa plant. Despite this shared origin, the psychoactive effects associated with THC, leading to a “high,” are absent in CBD, as it does not induce intoxicating effects.

Given that both cannabinoids hail from the same plant, questions arise about whether THC and CBD would both appear on a drug test. Continue reading to delve into the mechanics of cannabis drug tests and explore what research indicates about the potential for CBD use to yield positive results.

Understanding Cannabis Drug Tests:

Cannabis drug tests primarily focus on detecting THC, not CBD. According to Dr. Kelly Johnson-Arbor, a triple-board certified medical toxicologist and co-medical director of the National Capital Poison Center in Washington, D.C., various types of drug tests can identify the presence of cannabis in the human body.

One prevalent method is the immunoassay, wherein a patient’s urine or other bodily fluids like blood are analyzed for chemicals resembling the active metabolite or breakdown product of THC. Dr. Johnson-Arbor clarifies that the immunoassay doesn’t directly test for the presence of THC and doesn’t offer insights into the level of impairment or the quantity of THC exposure.

While immunoassays are cost-effective, readily available, and yield quick results, their susceptibility to false positives and false negatives categorizes them as presumptive screening tests. Confirmatory testing, often employing mass spectrometry, is a subsequent step in many organizations. Mass spectrometry, considered the gold standard for drug testing, relies on advanced techniques to detect compounds based on their unique chemical structures. This method is usually combined with other sophisticated approaches. However, mass spectrometry is more costly, time-consuming, requires highly trained personnel, and may have results delayed for days or weeks.

THC, being fat-soluble, can be detected in drug tests for up to three days after a single use and over 30 days after heavy use. Chronic THC use may lead to its accumulation in fatty tissues, gradually releasing into the bloodstream over time.

Determining the Threshold for a Positive THC Result:

There is no standardized THC level applicable to all drug tests. Dr. Johnson-Arbor notes that different laboratory test manufacturers may establish varying cutoff levels for positive THC results. The initial immunoassay test typically sets the cutoff level for THC at 50 nanograms per milliliter of urine. This figure represents the concentration of THC metabolites in urine but doesn’t precisely reflect the actual THC quantity used by the individual undergoing testing.

Concerns About CBD and Drug Tests:

The potential for diamond cbd oil to appear on a drug test is contingent upon the THC content in the CBD product consumed, a factor that may be more prevalent than commonly assumed.

Dr. Johnson-Arbor emphasizes that CBD products lack robust regulation and may harbor undesired contaminants, including THC or other illicit substances. A 2017 study analyzing 48 CBD products revealed that less than one-third accurately labeled their CBD concentration, with 21% containing THC[1]. Another study examining 67 CBD-containing food products in Germany found 25% had THC levels exceeding the lowest observable adverse effect level (LOAEL) of 2.5 milligrams per day.

Regular users of CBD products should be vigilant, recognizing the potential presence of problematic ingredients. While CBD itself may not induce a “high” or trigger a positive drug test, products with higher THC levels than claimed by the manufacturer can pose issues.

Does the Type of CBD Matter?

CBD is sourced from either hemp, a specific strain of the cannabis sativa plant, or THC-containing cannabis. Hemp-derived CBD should adhere to the FDA-mandated limit of 0.3% THC, but testing has shown occasional deviations from this legal threshold. A 2021 study examining hemp-derived CBD users found detectable THC levels in urine samples four weeks after discontinuation, challenging the assumption that hemp-derived products ensure exemption from drug testing concerns[2].

Dr. Johnson-Arbor underscores that any positive THC result, even if caused by contaminated CBD products, can have serious legal ramifications due to federal cannabis illegality. However, broad-spectrum CBD and CBD isolate products are less likely to be tainted with detectable THC, thanks to specific extraction methods designed to remove THC, along with other terpenes and cannabinoids in the case of CBD isolate.

Ensuring a THC-Free CBD Product:

Unfortunately, consumers face challenges in determining the THC content of a specific CBD product due to the industry’s limited regulation.

“As the CBD industry lacks comprehensive regulation, there is no foolproof method to ascertain whether a particular CBD product contains THC or not,” cautions Dr. Johnson-Arbor. While some manufacturers provide test results asserting the absence of THC, these outcomes often represent a single batch of CBD. They don’t necessarily reflect the composition of every product sold by the company over time.

Ensuring CBD Product Safety:

It’s crucial to prioritize products that come with a Certificate of Analysis (COA), providing a comprehensive breakdown of the compounds present in a CBD product. Typically available on the company’s website or upon request, a COA is essential for transparency. The absence of a COA should raise concerns, suggesting either a lack of testing by the company or a reluctance to share test results with consumers.

In essence, it’s possible for CBD to result in a positive drug test. While there are measures one can take to assess a product’s THC content, the accuracy of labeling remains uncertain due to the limited regulation of CBD products. Always exercise caution and verify the credibility of CBD products to minimize the risk of unexpected outcomes on drug tests.
