Recent research has shown that CBN makes it harder to pass a drug test. The researchers from the University of Utah discovered that CBN may react with THC-detecting tests.
A false-positive result requires a concentration at least five times the THC cutoff level. This means that a typical THC test with a cutoff of 50 ng/mL can detect 250 ng/mL of CBN in your urine, provided you are using a pure CBN product that does not contain THC. On the other hand, even 100 ng/mL may be enough to fail a drug test if your CBN product contains trace amounts of THC.
