Outcome measures
Primary outcome
Correlation coëfficiënt of liking of e-liquid flavors by smelling versus liking of e-liquid flavors by vaping, for smokers as well as for non-smokers
Secondary outcome
Liking, intensity, familiarity, and irritation (average and correlation coëfficiënt between smelling and vaping) for smokers as well as for non-smokers
Background summary
Research on e-liquid flavors could be performed through smelling or tasting ('vaping') experiments. The main objective of the Smell-e study is to determine if liking through smelling is comparable to liking through vaping, for smokers as well as for non-smokers. If this is the case, we may be albe to assess liking of e-liquid flavors in future research by performing smelling experiments only.
Study objective
If there is a correlation between liking by smelling and liking by vaping, future experiments on e-liquid flavors would require smelling experiments only.
