RESUMO
There is little scientific knowledge about e-cigarette use in South Africa. This study aimed to describe the risk factors and perceptions of selected Johannesburg-based users of e-cigarettes. A self-administered questionnaire was used to collect data from a convenient sample of 188 participants, of which 160 were males and 28 females. The survey results showed that participants used e-cigarettes at home (n = 28/ 14.8%), work (n = 76/ 40.4%), tertiary institutions (n = 50/ 26.5%) and in their vehicles (n = 24/ 12.7%), while (n = 96/ 51%) used the product in the presence of children. 57 participants (30.3%) started using e-cigarettes as a smoking cessation strategy, while 46 (24.4%) used it to manage smoking cravings. Most participants believed that e-cigarettes are addictive (n = 156/ 82.9%) and unhealthy (n = 139/ 73.9%). This study highlights the need and opportunity to improve public health action in the prevention and management of risks posed by e-cigarette products to users and non-users.
