Abstract

A series of research studies was conducted to determine if there would be changes in the handwriting of 35 men and women after they had been drinking. Handwriting samples were taken before the participants had consumed any alcohol and again after the drinking period had ended. Deterioration in the handwriting was charted. Based on this study, the handwriting could not be used in any way to measure accurately the blood alcohol concentration of a writer. The results of the handwriting comparisons are discussed.
