Two experiments were conducted to examine whether using e-cigarettes with occasional use of regular cigarettes prevented relapse after extinction. In Experiment 1 (ABAC with a multiple-baseline design), six short-term smokers who wanted to stop smoking were asked to use e-cigarettes and were allowed to smoke 20 % of the usual number of regular cigarettes per day during the partial reinforcement period. Experiment 1 demonstrated that using e-cigarettes reduced the amount of smoking even after extinction. In Experiment 2 (ABAB design), which involved a single long-time smoker and partial reinforcement, the participant was unable to maintain low rates of smoking after the experiment. However, the excessive smoking (regular cigarettes > 15 per day) observed before the experiment was prevented. This study suggested that a partial reinforcement procedure (occasionally smoking cigarettes) prevented relapse after extinction without hardship in some smokers.

进行了两项实验，以检查偶尔使用电子烟并偶尔使用普通香烟是否可以防止灭绝后复发。在实验 1（多基线设计的 ABAC）中，6 名想要戒烟的短期吸烟者被要求使用电子烟，并在部分强化期间允许每天吸 20% 的普通香烟数量时期。实验 1 表明，即使在灭绝后，使用电子烟也能减少吸烟量。在涉及单个长期吸烟者和部分强化的实验 2（ABAB 设计）中，参与者在实验后无法保持低吸烟率。然而，在实验前观察到的过度吸烟（普通香烟 > 每天 15 支）被阻止了。
