The lesson is that if you're trying to quit, whether using an over-the-counter method or a prescribed medication, follow the directions and your chance of success will increase.

　　从以上事例中，我们可以认识到：如果你正在试图戒烟，无论是使用非处方的或者医师给出的治疗方式，只要你遵照各项说明，那么你成功的机会就会大大增加。

　　But following directions with e-cigarettes may be moot. Lerman says she doesn't have any e-cigarette stories because none of her clients has mentioned that method of trying to quit.

　　但是就算你谨遵说明使用电子香烟，它的戒烟效果依然有待商榷。勒曼说她手上没有任何关于电子香烟的案例，因为在她所指导的戒烟者中，没有一个人向她提起过用电子香烟去戒烟的事情。
