Will CBD make me test positive on a drug test?

CBD has become quite the buzz word and for good reason: it has shown to reduce pain, nausea, inflammation, spasms, intestinal contractions, artery blockage and more all without causing a high.

Now that cannabidiol (CBD) has become as much of a household name, some of the patients who experiment with this alternative medicine have concerns about whether it will cause them to fail a drug test. They are worried that their use of the non-intoxicating cannabis derivative will bring them trouble with their place of employment or disqualify them from any number of benefits in which the federal government must sign off. 

However, since there are many types of cannabis-derived CBD products on the market made from the same plant as THC (everyone’s favorite recreational cannabinoid) and hemp-derived products with extremely low THC levels, many people are left wondering if CBD will show up on a workplace drug test. while pure CBD will unlikely show on your drug test , full spectrum CBD usually contain a trace amount of THC that is less than 0.3%.

Drug tests weren't designed to detect CBD.


Drug screens are only searching for one specific cannabinoid when trying to determine whether the subject has been using marijuana, and that is THC.There are many reasons an employer might require drug screening – safety, legal protection, improved productivity, or even federal mandates – but the ultimate goal is to determine impairment, not a medical regimen. Therefore, most drug screens are not designed to detect CBD, a non-psychoactive cannabinoid derived from either hemp or cannabis plants.

Rather, most employers use either a 5-panel or 10-panel drug screen, both of which test for THC-COOH (what THC turns in to after the body metabolizes it). In addition to THC, the 5-panel drug screen tests for cocaine, opiates, PCP, and amphetamines/methamphetamines while the 10-panel screen also tests for barbiturates, propoxyphene, benzodiazepines, methadone, and propoxyphene. Though the 10-panel test contains more recreational drugs, it also contains more pharmaceutical drugs which have become a growing epidemic over the last few decades.

High Doses of CBD Could Trigger a Positive

Because hemp products can legally contain up to .3 percent THC, regularly consuming high doses of CBD products can trigger a positive result. 


Though tests are being developed to detect CBD metabolites, most employers don’t really care about it, they just want to know if you get high.

Medical Employers and Drug test Professionals Want to Know What Cannabinoids are in Your System

Though an employer’s reason for drug testing is to determine your ability to remain safe and productive at work, a medical professional has a whole different reason: to determine what medications to give you to keep you safe. Non-disclosure of cannabis consumption could alter the effectiveness of sedatives and other pain medications.

Because cannabis and anesthesia are both depressants, mixing the two could make for a dangerous mid-surgery interaction. Though surgeons recommend avoiding cannabis consumption prior to surgery to avoid a miscalculation in anesthesia, some medical professionals will conduct a pre-surgery drug screening to ensure all chemicals and medications floating around in the body be identified prior to putting you under.

Employers and Drug test

Unlike other substances including alcohol, THC can remain in your system for about 30 days. Based on each individual metabolism body weight and BMI (body mass index), your test results may vary

Your body can store cannabinoids like THC and CBD in the fatty cells . The greater the patient weight the longer THC can stay in your body . A small amount of THC though non intoxicating can be stored in your body fat cells and produce a positive drug test . 

Employees can appeal drug test results and ask for a second test for confirmation. Confirmatory testing will look into the concentration of THC instead of just a positive or negative . Also employees are encouraged to use the certificate of analysis that show a trace amount of THC and let your employer know that you are using CBD product that has a small amount of THC .
