Which of the following factors does NOT influence blood alcohol content?

Blood alcohol content (BAC) is a measure that quantifies the amount of alcohol present in a person's bloodstream, and several physiological and behavioral factors influence its level. Your weight plays a significant role; as a general principle, the more someone weighs, the more water content is in their body, which can dilute the alcohol consumed, generally leading to a lower BAC. The amount of alcohol consumed is a direct determinant of BAC, as more alcohol in the bloodstream typically results in a higher BAC. Similarly, how quickly alcohol is consumed can affect BAC levels because rapid consumption does not allow the body sufficient time to metabolize the alcohol, leading to an increased concentration.

Height does not have a significant impact on BAC calculations. Instead, it is primarily an indirect factor, as it often correlates with body weight. Therefore, while weight is critical in understanding BAC due to its effects on body water content, height alone does not directly affect how alcohol is processed in the bloodstream, making it the factor that does not influence BAC levels.
