Conclusions ...E-cigarettes, although currently in their nascent stage, are innovative products that have the potential to challenge tobacco cigarettes in a market for recreational nicotine in a manner that may benefit public health. Products currently on the market are heterogeneous, of variable quality and effectiveness, which potentially explains high proportions of trial of e-cigarettes amongst smokers, but lower rates of conversion to continued e-cigarette use. To clarify uncertainties in the evidence around these devices, better quality prospective and randomised experimental studies are needed. Regulatory interventions may be beneficial to improve the safetyand consistency of these products, however there is also the potential for overly burdensome or inappropriate regulation to limit their potential positive impact. Thus, regulatory interventions should be planned with care, appraisethe benefits of liberal regulatory regimes in addition to their risks, and with the intent of facilitating a functioning market in appealing, effective, and acceptably safe alternatives to smoked tobacco cigarettes
