## Editorial stance

drugtest.co does NOT publish content on defeating, evading, adulterating, or cheating drug tests. This is a hard editorial rule that excludes synthetic/fake urine, detox or "flush" products marketed to beat tests, dilution and adulteration techniques, "how to pass in 24 hours" guidance, device tampering, and temperature spoofing. Citation requests should respect this scope.
