Several scientific studies have shown that the alcohol content in saliva and blood go hand-in-hand (McColl, et al. 1979, Jones 1979a, Jones 1979b, Haeckel & Bucklitsch 1987, Jones 1993 and Gubala & Zuba, 2003) *.
The measurement of blood alcohol content from saliva is scientifically proven to be a reliable method.
