The Royal Australian and New Zealand College of Psychiatrists' (RANZCP) 2018 position statement supports increased, regulated availability of e-cigarettes (ECs) as a harm-reduction measure and recommends further research into their use. Aligned with this recommendation, we aimed to critically evaluate the RANZCP's stance on this issue through a literature review focused on the areas identified in the position statement as requiring further investigation: (1) the adverse health effects attributable to ECs; (2) use of ECs for smoking cessation (particularly for people living with severe mental illness); and (3) EC-associated risks for nicotine naïve young people. We identified and summarised evidence of harm attributable to ECs that is particularly relevant to young people through direct adverse health sequelae, onset of nicotine dependence and increased risk of combustible cigarette (CC) use. A small number of studies suggest ECs can be used for harm-reduction purposes in people diagnosed with nicotine dependence and severe mental illness. However, these results must be considered alongside robust evidence supporting the effectiveness of existing pharmacological interventions for smoking cessation in people with severe mental illness. The position statement is in urgent need of review in line with the available evidence.
