Close to the beginning, when the doctor came over to check the kid after "Tony" showed him why he didn't want to go to the Overlook, she and Wendy are sitting in the living room and she starts to smoke a cigarette. One scene, they show Wendy as she's talking and then it switches to the doctor. About 10 seconds later, they show Wendy and almost half the cigarette is burned. The next time they show her, not long after, the cigarette is almost gone.
