In this study, the reproducibility of blood alcohol concentration (BAC) - time profile for the same individuals were investigated. Five Korean males were made to drink 55.5 g of ethyl alcohol (neglecting body weight) in the form of undiluted Soju (22% v/v), Korean popular liquor, within 30 min and each drinking sessions were performed for five times. Two kind of side dishes, a sliced raw fish and a sweet and sour pork, were served alternately along with alcohol. The peak BAC reaching time, the maximum BAC and the reduction rate of BAC of an individual varied greatly even though the dose and drinking time interval were not changed. Also, the food taken along with alcohol varies the shape of BAC - time profile. From the repetitive drinking sessions we can know that the BAC - time profile of an individual is not a reproducible one even though the dose, kind of liquer, drinking time and food were maintained constantly. It means that any assumption of blood alcohol concentration of an individual at a previous time stage based on the alcohol dose can not be justified because of large fluctuation of BAC-time profile of an individual.
