A saliva test (also called an oral fluid drug test) is a quick roadside screening method used by police to detect drugs in a driver’s system. It's commonly used during traffic stops or random roadside checks to enforce drug-driving laws. Most saliva tests screen for common impairing drugs such as: Cannabis (THC), Cocaine, Methamphetamine / Amphetamines, Ecstasy (MDMA), Benzodiazepines (in some regions), Opioids (in some cases).
