 Shin, et al., reported in 2008 that salivary detection of ethanol and three of its metabolites (methanol, ethylene glycol, and diethylene glycol) had “relatively high sensitivity and specificity” and that such testing facilitates rapid diagnosis of alcohol intoxication.A 2002 study demonstrated that there was good agreement between saliva and breath ethanol analysis, and that chromatographic saliva ethanol assay is “specific…[and] shows good accuracy and precision.” In 2011 Vindenes, et al., investigated the viability of drug abuse monitoring using saliva, comparing this method to urine drug detection.Researchers found that several drug metabolites were detected more frequently in saliva than in urine; this was true for 6-monoacetylmorphine, amphetamine, methamphetamine, and N-desmethyldiazepam.
