However, heavy use can be detected up to 2 weeks after use and chronic use up to 30 days or 1 month later. Although urine tests can detect minute concentrations, they are not reliable for determining use volume, or whether your drug use was a one time experience or for an extended period of time. As mentioned above, CBD will not trigger a positive drug test.

- In June of 2018, Mark Pennington received troubling news from his ex-girlfriend, with whom he shared custody of their 2-year-old son.
- A drug test had returned positive for THC, the intoxicating compound in marijuana; evidently their son had been exposed to it, presumably in Mr. Pennington’s presence.
- It is important to note that hemp CBD vs THC are very different from each other, andCBD dosageis dependent on whether you are considering takingCBD for anxietyand depression.
- She had taken a hair follicle from the boy, she said, and had it analyzed at a lab.

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 , this is somewhat surprising.
The following are some reasons why CBD can test positive for THC in a drug test. The increasing consumption of CBD products has created a challenge when testing employees for drug use in the workplace. Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products.
This means that contamination of the CBD with THC may and does occur, and this may show up on a drug test, depending on the cutoff level of the test and other factors listed below. Blood testing is considered to be invasive and is therefore the least common form of testing for THC. The tests are further limited because the compound leaves the bloodstream relatively quickly after use when compared with saliva, urine, and hair testing. Blood tests for THC are usually accurate for 24 to 72 hours after use but can detect THC for up to 7 days depending on an individual’s blood renewal system. On the other hand, these tests are accurate and are unlikely to produce a false-positive as is the case with saliva testing and urine analysis.
While both cannabis and hemp produce CBD, the products derived from hemp and cannabis are entirely different. Although less than 0.3% of THC is legal, different types of drug tests still vary in their thresholds for detecting THC. For example, the traditional urine drug test detects THC content when the amount of THC is above 50 ng/mL. Most CBD products are hemp-derived; hemp-derived CBD contains less than 0.3% of THC, which is federally legal, while marijuana-derived CBD contains 0.3% or more THC. However, there have been cases where CBD oil users have failed a drug test due to positive THC results.
In a confirmatory test, a metabolite of marijuana is measured, called delta-9-tetrahydrocannabinol-9-carboxylic acid, CBD gummies 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. However, because most CBD products are classified as a supplement, it is not regulated for safety and purity.
But it is also something to be aware of, because it may mean that what is considered a pass in some circumstances may be considered a fail in others. Federal workplace cutoff values for marijuana metabolites are 50 ng/mL for immunoassay screening tests .
Just last year, a medically reviewed study found that a cannabinoid known as CBN, often called CBD’s "cousin," can trigger a false positive in lab tests for marijuana use—even in small doses. Urine drug tests, also called urinalysis, check urine for THC metabolites. More complex job positions often use more multifaceted drug screening methods.
It is unlikely that a blood test will be used to detect marijuana or CBD use. Urine testing can detect THC concentrations between 2 and 5 days after use.
