To the Editor We read with great interest the Research Letter in a recent issue of JAMA Internal Medicine by Auer et al1 showing the presence of volatile organic compounds, polycyclic aromatic hydrocarbons, and carbon monoxide in the emissions of a tobacco heating product (THP) recently marketed by Philip Morris International (PMI).
These findings differ significantly from those presented by PMI as well as by PMI’s competitors,2-4 and Auer et al1 argue that this information should come from independent research rather than from manufacturers.
