Vapour particles evaporate within seconds of exhaling, according to a 2018 study produced by four organisations including blu’s parent company fontem ventures , published in the nicotine & tobacco research journal. For e-cigarettes, the study found that even in a room with no ventilation, the liquid aerosol droplets evaporated so quickly that the particle concentration in the air returned to background levels within seconds. In contrast, for conventional cigarettes, the particle concentration in the room only returned to background levels after 30-45 minutes. Dr grant o’connell, corporate affairs manager at fontem ventures and senior author of the study, said: “this data adds to the growing body of evidence that vaping indoors is unlikely to pose an air quality issue. In general, vaping indoors is often regarded as safer than regular cigarettes – but what about the impact on our air quality? how does smoking and vaping compare? here we explore the possible consequences of first-hand vaping, in addition to the broader impact on air quality for those nearby. Is Vaping Allowed Indoors? Most countries leave it open for families and establishments to decide the answer to the question: is vaping allowed indoors? as such, it is a
