Figure 4. Electronic nicotine delivery systems Google searches by select predictors for tobacco control and smoking social norms, 2014.

Figure 4

Panels (a, c, e, and g) compared all ENDS searches in 2014 by state according to the smoking prevalence, social unacceptability of smoking,(20) cigarette excise tax, and clean indoor air grade –as detailed in the text. Searches were measured using the mean relative search volumes (100=highest search proportion, 50=50% of the highest search proportion for all Google searches on ENDS) for all of 2014. Panels (b, d, f, and h) replicate the same analyses but using the proportion of all ENDS searches that included terms indicative of vaping (e.g., “best vaping cigarettes”) by state as the outcome.
