The use of electronic cigarettes, commonly known as vaping, has exploded in popularity worldwide and in Malaysia over the past decade. Driven by factors like high conventional tobacco cigarette smoking rates, vaping has emerged as an alternative nicotine delivery system for many smokers looking to quit or reduce harm. However, the meteoric rise of vaping has also raised mounting concerns around uptake by youth and adolescents, as well as potential health effects from long-term use.
