Tobacco Advisory Group, Royal College of Physicians. Nicotine without smoke: Tobacco harm reduction. London, RCP, 2016.

It shows that, for all the potential risks involved, harm reduction has huge potential to prevent death and disability from tobacco use, and to hasten our progress to a tobacco-free society.
