Introduction: regulating e-cigarettes in the face of uncertainty

Abstract

This chapter introduces the theme of the book. In this context, it looks at the variety of approaches taken by regulators around the globe with respect to e-cigarettes, as well as at the science that stands behind specific regulatory choices. It also delimits the scope of the book and clarifies terminological nuances. Against this background, the chapter summarizes and critically assesses the findings of the individual authors relating to: (i) the factors that influence the particular paths taken in different jurisdictions; (ii) general features of an optimal regulatory model for e-cigarettes; and (iii) constraints imposed by international and European rules on regulators in this policy space. The chapter also offers some general observations as to the possible future directions of e-cigarette regulation.
