The swift evolution of the e-cigarette market, the diversity of available devices and e-liquids, and the lack of consistent regulation around these products means that limited data are available on the possible health effects of using e-cigarettes.
British American Tobacco is undertaking research into a number of areas, including:
how the main categories of device perform under different conditions of use, and how users use e-cigarettes
the constituents of the aerosol, including the likelihood of thermal breakdown of the constituents of the formulation
developing procedures for assessing the effects on the human body of inhalation of the constituents of the aerosol.
