The Tobacco Control Data Initiative (TCDI) is implemented by Development Gateway, an international non-profit, in partnership with the Research Unit on the Economics of Excisable Products (REEP), based at the University of Cape Town. The TCDI is funded by the Bill & Melinda Gates Fundation. Its goal is to provide Sub-Saharan African governments with country-specific data for tobacco control policy design and implementation. The South African E-Cigarette Survey (SAES) was conducted in 2022 as a project of the TCDI. SAES 2022 was a telephone survey that collected data on the use by adults in urban South Africa of electronic nicotine and non-nicotine delivery systems (ENDS) and heated tobacco products (collectively defined as “e-cigarettes”), as well as traditional cigarettes. The aim was to estimate e-cigarette use prevalence and provide a demographic profile of e-cigarette users in South Africa, as well as to analyse the relationship between e-cigarette use and cigarette use in the country (particularly sequence of use for the two products).

Version 1: Edited, anonymised data for non-commercial use
The survey collected data on e-cigarette use prevalence in South Africa and demographic information on e-cigarette users in the country. It also collected data on the relationship between e-cigarette use and the use of traditional cigarettes, including sequence of use for the two products.
The data was collectected from households in urban areas in South Africa
The lowest level of geographic aggregation in the data is Province
The universe for the survey was adults (18+) in households in urban areas in South Africa.

Data Collection Notes
SAES 2022 was a telephone survey
The survey instrument was a single CATI-based questionnaire, with different routing and modules depending on the type of respondent being interviewed:
1) e-cigarette users who were routed to a long-form section of the questionnaire which collected demographic and usage data.
2) users of traditional cigarettes, who were also routed to a long-form section of the questionnaire (up to a maximum of 700 respondents)
3) users of traditional cigarettes were routed to a short-form version of the questionnaire (once the quota of 700 respondents was filled) to provide only demographic data
4) non-smokers (users of neither e-cigarettes nor traditional cigarettes) who were also routed to a short-form questionnaire that collected only demographic data.
The questionnaire was changed between the Pilot Survey and Survey Phase 1, and again between Phase 1 and Phase 2. The changes are documented in the South African E-Cigarette Survey 2022 User Manual.
