Drug tests are commonly given amongst employers to ensure their employees are not under the influence of illegal, and in some cases, prescription drugs. Although drug tests can only detect past drug usage, employers use them as an indication of an employee’s ability to perform. They may only be given at the start of employment or periodically. Typically, urine drug testing (UDT) is used by employers because it is cheaper to use and the results appear much quicker than other forms of drug testing. However, drug screenings can also be completed by testing blood, sweat, saliva, and hair.

Drug Test For THC, Not CBD

In most states, drug tests screen for THC usage, the psychoactive compound in marijuana that produces the “high” sensation. They do by using antibodies that react to specific amounts of the compound and its primary metabolite, the substance that helps THC metabolize in the body. If the antibodies detect this amount or higher of THC and its metabolite, then the screening will come back with positive results.

Because THC and CBD are both types of cannabinoids, many people who use CBD hemp oils are concerned that CBD will show up on a drug test. However, CBD is a different compound and reacts with varying metabolites in the body. Drug screenings are not designed to detect CBD because it is a non-psychoactive drug and consequently does not impair users’ mental state. Therefore, drug tests designed to identify THC usage will not detect normal CBD usage.

The Caveat With Full Spectrum CBD Oils

There is one caveat, though. Some preliminary drug screenings may test positive for marijuana use if an individual uses too much CBD. Since marijuana and hemp plants (where CBD is derived from) are both types of cannabis plants, they share common compounds. It is possible that non-THC metabolites found in CBD oil may cause a reaction in a drug screening’s antibodies because they are so similar to THC metabolites, mainly since most CBD products contain trace amounts (less than 1 percent) of THC. This could result in a “false positive,” and another drug test would have to be taken to confirm. The results of the new drug test should come back negative for THC, which means the CBD user will be cleared.

Overall, drug tests do not screen for CBD, so users should not worry about usage affecting their results. However, if you are at all worried about the trace amounts of THC found in most CBD hemp oils coming back on a drug screen, then it is best to avoid taking CBD for a few days before your test.
