Reviewed for accuracy by licensed clinical professionals.
Delta-8 THC metabolizes to the same compounds as delta-9 THC, meaning standard marijuana drug tests WILL detect it.
Detection
Urine: 3-30 days depending on frequency. Same as regular THC. Blood: 2-3 days. Hair: up to 90 days. Standard THC immunoassay panels cannot distinguish delta-8 from delta-9.
The legal trap
Delta-8 is legal in some states but triggers positive THC results on all standard drug tests. Confirmatory GC/MS testing may distinguish them, but many employers accept the initial positive.
