The Tobacco & E-Cigarette Survey Among Malaysian Adolescent (TECMA) 2016 is a nationally representative study which has been carried out to obtain the latest information on tobacco and e-cigarette/vape usage among Malaysian adolescents as there is no national study on this subject. The objectives of this study were to determine e-cigarette/vape usage, to assess student related knowledge and behaviour towards e-cigarette/vape usage and to determine the prevalence of dual users (tobacco and e-cigarette/vape users) among Malaysian adolescents. A two-stage stratified cluster sampling design was used for this survey to produce a nationally representative data. The target population were school going adolescents. A total of 14,833 students from 138 schools from 15 states were selected. A self-administered questionnaire was used as a tool for this survey.
