He is the perfect storm of a card-carrying “public health” person who is harmful to both public health science and the public’s health: terrible at scientific/analytic reasoning, and freely promotes junk science; believes that top-down authority, particularly promoting prohibition, is the defining characteristic of public health; will make any sciencey claim that seems to support his political positions, regardless of the lack of scientific support; displays no apparent humanitarian concern despite working in a field that can only be justified by such; is the worst kind of gadfly (parachuting in to topic areas he clearly knows nothing about and making sweeping declarations as if he is an expert); and does not even seem to display much more scientific expertise on tobacco, the subject he has been working on for decades.
