What Drugs Can a Saliva Drug Test Locate?
Many of the most commonly abused drugs can be detected in saliva drug testing including marijuana, thc, heroin, cocaine and amphetamines. Saliva drug tests cannot be used to detect historical drug use. Most drugs do not linger in saliva and disappear in anywhere from twelve to twenty four hours. Because of this saliva drug testing is being considered for drug detection in situations where recent drug use must be detected including vehicle and equipment drivers, those involved in workplace or other accidents and not as a use to detect past drug use.
