Even though many people are increasingly using medical marijuana and other cannabis-based products to treat depression, sclerosis, epilepsy, anxiety, and a host of other symptoms, many work places will not accept people who test positive in a drug screening. This means that many of those who take medical marijuana might be out of luck when it comes to these sorts of tests, but how will those taking cannabidiol (CBD) products be affected?
Marijuana is commonly detected in the bloodstream through a urine test where immunoassay and antibodies are used to pick up on THC’s main metabolite, 11-nor-delta9-caboxy-THC (THC-COOH). It is recorded as a positive if the urine same has at least 50 ng/mL of THC-COOH. If it is under that level, a GC/MS (Gas Chromatography/Mass Spectrometry) test is executed to test for positive levels if there is at least 15 ng/mL of THC-COOH.
Luckily, the drug screening that test for THC-COOH shouldn’t normally react to non-psychoactive cannabinoids such as CBD. Those who take an incredibly high amount of CBD products or hemp oil everyday could result in a “false positive” because other non-THC chemicals might be detected by the immunoassay, though the much more accurate GC/MS test should always result in a negative.
The vast majority of high-quality CBD-rich hemp oils contain very little THC. In fact, THC levels of hemp oil are usually 400% to 600% less than that of marijuana. However, someone who ingests 1000-2000 mg of hemp oil a day could be consuming 3-6 mg of THC, which would detect as positive in 11%-23% of drug screening tests. Someone only taking 3-5 servings of hemp oil a day would only have 0.5mg of THC in their body, which would result positive in less than 1% of drug screenings.
Consumers should be aware of the THC levels in their products and know that more high-quality products will have less THC levels than other lower-quality brands. Those who consume only high-quality oils and don’t take an excessive amount of it per day should have nothing to worry about when it comes to drug screenings.
