This report explores consumer e-liquid preferences, choices and behaviours based on our consumer survey conducted in December 2018. As the respondents were members of the Consumer Advocates for Smoke-free Alternatives Association (CASAA), we believe most respondents were interested in the vaping sector and would potentially have higher levels of consumption. Similar studies were also carried out in 2016 and 2017, with many questions remaining the same. This enables us to track and analyse the development of consumer tastes and preferences over a three-year period. The report also explores the demographics of low-, medium- and high-strength nicotine users, and their preferences and behaviours.
