Figure 1.

Concept map displaying 12 e-cigarette user-identified clusters and statements describing a specific action/reaction if the only e-liquid flavors available for purchase in the U.S. were tobacco only flavor, menthol only flavor, or unflavored (and no other flavors). Numbered points on the map that are closer to one another represent statements of more similar content whereas points on the map that are further apart represent statements of less similar content. Greater number of layers in clusters indicate higher mean ratings of statements within each cluster based on the rating task.
