Cognitive and Affective Mechanisms Underlying an Olfactory Approach to Modify Cigarette Craving

Each participant in the pleasant odor condition will sniff an odor that they rated as the most intense out of a sample of odors rated to be pleasant. If this odor is the same as their self-reported preferred e-cigarette flavor, we will choose the next most intense odor out of the odors rated to be pleasant. Odors are generic and commercially available in supermarkets such as vanilla, coconut, and chocolate. Importantly, the investigators are not testing the specific odors, rather the participant's idiosyncratic response to a menu of odors. In other words, the key is that each participant in the experimental condition receives the odor that they like the best, regardless of which one it is.

Each participant in the odor blank condition will sniff a neutral olfactory cue (odor blank). This involves a container with no added scent. This serves as the control condition.
