Introduction

Commercial establishments where alcoholic beverages are served (e.g., bars, restaurants) and social hosts who serve alcohol in non-commercial settings may find themselves potentially liable for damage, injury, and/or death caused by alcohol-related accidents involving individuals they have served. Critical issues addressed by toxicologists often involve interpretation and/or estimation of blood alcohol concentration (BAC) levels, associated clinical effects, and degrees of intoxication.

This white paper outlines how toxicologists help resolve questions regarding liability in the alleged over-service of patrons or guests that has led to damage, injury, and/or death.

Clinical Effects of Alcohol

Alcohol consumption affects mental, cognitive, and other physical functions in a dose-related manner (e.g., more consumption is associated with greater effects). Toxicologists combine BACs with observed behavior to determine associated levels of impairment/intoxication.

It is generally accepted by toxicologists that the degree of physical and mental impairment from alcohol correlates with BAC. In general, higher BACs produce increased impairment and greater degrees of intoxication. For example, the typical effects of a 0.02% (or 0.02...
