Editing Blood alcohol content (section)

===By training===
If individuals are asked to estimate their BAC, then given accurate feedback via a breathalyzer, and this procedure is repeated a number of times during a drinking session, studies show that these individuals can learn to discriminate their BAC, to within a mean error of 9&nbsp;mg/100 mL (0.009% BAC).<ref>{{cite journal |last1=Huber |first1=H |last2=Karlin |first2=R |last3=Nathan |first3=P E |title=Blood alcohol level discrimination by nonalcoholics.
