Pure CBD is not tested for on standard drug panels. However, many CBD products contain trace THC that can accumulate and trigger positive results.
The THC problem
Full-spectrum CBD products contain up to 0.3% THC (legal limit). With daily use, this trace THC can accumulate to detectable levels. Broad-spectrum and isolate products should not trigger tests but quality varies.
If you are drug tested
Use CBD isolate or broad-spectrum products from reputable manufacturers with third-party testing. Full-spectrum products carry risk of positive THC results.
