IQOS is the most popular heated tobacco product (HTP) worldwide, marketed by the world’s largest transnational tobacco company, Philip Morris International (PMI).1 HTPs comprise two components: an electronic battery-powered device, which does the heating, and a cigarette-like stick, which contains the tobacco. These components are sold separately and often under separate brand names. For example, tobacco sticks for IQOS are called ‘HEETS’, ‘TEREA’ and ‘LEVIA’.2
