    We thank Tobacco Control for the opportunity to respond to the comment above. Our study was obviously not looking into the harms of secondhand aerosol from e-cigarettes (SHA). Our paper departs from previous compelling research on the harms of SHA and assesses the prevalence and duration of such exposure among e-cigarette non-users, i.e., bystanders who are potentially exposed to the aerosols emitted by e-cigarette users.

    Firstly, it is clear that we conducted the study on the basis of knowledge that bystanders were involuntarily exposed to potentially hazardous SHA in many places. We have clearly mentioned the growing evidence that supports our assertion about the potential harms of SHA in the Introduction and Discussion sections of the paper. SHA contains many toxicants, including nicotine, particulate matter and carcinogens (e.g., volatile organic compounds, polycyclic aromatic hydrocarbons, formaldehyde, acetaldehyde and tobacco specific nitrosamines-TSNAs). As mentioned, this evidence comes from previous scientific research (please, foresee the references 11 to 14 of our paper). Of special interest, fine particulate matter (PM2.5) concentration increased during e-cigarette use sessions with human volunteers in settings such as a room[1–3], during vapers’ conventions[4,5], and in vape shops and their neighbouring businesses[6]. Some TSNAs, such as N-nitrosonornicotine and nicotine-derived nitrosamine ketone, which are carcinogenic[7], hav...

    I wish to express my dismay with the clear and obvious intention to promote an agenda of fear. One might ask why you are not looking to see whether there actually are any harms from second hand aerosol as the study clearly acts upon a preface that this is the case. I would point you to the CDC's own testing of the air quality found here. Something smells a lot less like science and a lot more like virtue signalling funded by an agenda eager to skip the important part of knowing what you're dealing with before searching for potential victims.
