Considerably reduced toxicant levels in heated tobacco prototype compared to cigarettes

Bristol, February 28th 2019 – New research* suggests that toxicants of notable public health interest are substantially reduced in the aerosol from our heated tobacco product (HTP) prototype, compared to smoke from a standard reference cigarette. HTPs generate a nicotine-containing aerosol with a tobacco taste through the heating of tobacco via an electrical device. The…
