THC delta-8 may show up on a regular drug test. Because it's chemically similar to THC delta-9, it can test positive for cannabis drugs, even if you don't consume “normal” cannabis products. If you know that you will be tested for cannabis, it's best to avoid products with delta-8 altogether. THC delta 8 can show up on a drug test because it has many characteristics similar to those of THC delta 9.However, if you don't pass a standard urine drug test, you can ask your employer to retest you, this time using gas chromatography and mass spectrometry.
This test will yield more accurate results because it specifically looks for the unique metabolites of THC delta 9.Unfortunately, the CBD, Delta-8 and Delta-9 that pharmacological tests seek are almost identical from a molecular point of view. This can cause problems for those who consume CBD and Delta-8, and cause a false positive for Delta-9 THC tests, as the body releases similar chemicals. Heavy Delta 8 users should be prepared to falsely test for drugs for 30 to 60 days, sometimes even longer. Some experts report that heavy users of delta-8 THC products may have their metabolites in their urine for 30 to 60 days.
Even after the perceptible effects of delta 8 THC have worn off, its “trail” remains in these places and can be detected during a drug test.
