实验1中8名只喝可乐的人（平均咖啡因摄入量= 157±74 mg/天）和实验2中16名同时喝可乐和咖啡的人（平均咖啡因摄入量= 1079 ± 201 mg/天）进行了6次独立的双盲每周试验。每项试验开始时都有一个随机交叉采样期，一天是不含咖啡因的可乐，一天是含咖啡因（33毫克/8盎司）的可乐。在随后的1天或2天的测试期间，参与者可以无限制地同时使用2种可乐。可靠的咖啡因自我管理发生在实验1中的8名参与者中的2名和实验2中的16名参与者中的4名。在实验2中，当参与者只接受安慰剂可乐时，自我报告的嗜睡，疲劳和头痛更高，但不是实验1。通过可乐自我摄入咖啡因既发生在咖啡因的主要来源是可乐的人中，也发生在咖啡因的主要来源是咖啡的人中。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Eight exclusive cola drinkers in Experiment 1 (mean caffeine intake= 157±74 mg/day) and 16 drinkers of both cola and coffee in Experiment 2 (mean caffeine intake= ₅79\+ 201 mg/day) underwent 6 independent, double-blind weekly trials. Each trial began with a randomized cross-over sampling period of 1 day of access to noncaffeinated cola and 1 day of access to caffeinated (33 mg/8 oz) cola. During the subsequent 1-or 2-day test period, participants had unlimited concurrent access to the 2 colas. Reliable caffeine self-administration occurred in 2 of 8 participants in Experiment 1 and in 4 of 16 participants in Experiment 2. Self-reported drowsiness, fatigue, and headache were higher when participants received only placebo colas in Experiment 2, but not Experiment 1. Caffeine self-administration via cola occurs both among people whose primary source of caffeine is cola and among those whose primary source of caffeine is coffee.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
