We examined the effects of providing drinks with half the alcohol level on alcohol consumption and blood alcohol concentration (BAC) of 4 patrons of a private club. Alcohol consumption was measured by observers and level of impairment was determined from breath samples obtained by digitalized ALERT (Alcohol Level Evaluation Road Tester) breath testing devices. An alternating treatments design was employed to compare the sessions during which people drank mixed drinks with their usual alcohol concentration with sessions during which they drank mixed drinks with half the alcohol concentration that cost half as much as the regular drinks. All 4 participants consumed less alcohol during sessions when they received drinks with the lower alcohol content. BAC was also less on all but two sessions during the low alcohol condition.
我们研究了为一家私人俱乐部的4名顾客提供酒精含量减半的饮品对酒精摄入量和血液酒精浓度（BAC）的影响。酒精摄入量由观察者测量，损伤程度通过数字化ALERT（酒精水平评估道路测试仪）呼气测试设备采集的呼气样本确定。采用交替治疗设计，比较人们饮用常规酒精浓度混合饮品的时段与饮用酒精浓度减半且价格仅为常规饮品一半的混合饮品的时段。所有4名参与者在饮用酒精含量较低的饮品时，饮酒量都有所减少。在低酒精含量情况下，除了两个时段外，血液酒精浓度也较低。
