Summary

Despite the explosive popularity of sweet flavored electronic cigarettes, there is little empirical evidence regarding how "sweet" flavors interact with different levels of nicotine to reduce its perceived bitterness and harshness, and thereby increase its appeal and additive potential. This study will serve to fill this knowledge gap through empirical psychophysical data that will determine the association between sweet flavor and nicotine and its link to the acceptance and rejection of vaped nicotine.
