Composition of heat-not-burn product emissions

QuackGuru: See Composition of heat-not-burn product emissions.

---

The '''composition''' of the '''emissions''' generated from '''heat-not-burn products''' are generally lower than that found in [[tobacco smoke|cigarette smoke]].<ref name=PieperMallock2018/> This is due to the comparatively low temperatures, the filter systems, and physical design.<ref name=PieperMallock2018/> The composition of what is produced is complex.<ref name=DautzenbergDautzenberg2018/> The main [[toxicant]]s found in the emissions of cigarette smoke (i.e., [[tar (tobacco residue)|tar]], [[nicotine]], [[carbonyl group#Carbonyl compounds|carbonyl compound]]s, and [[nitrosamine]]s) are also found in the emissions of these products in varying concentrations.<ref name=KaurMuthumalage2018/> There is a lack of agreement on the composition of the emissions in the documented literature, as of 2018. These products, however, still pose health risks.<ref name=PieperMallock2018/> Lower levels of harmful emissions has been shown, but lowering the risk to the smoker who transitions to using them has not been shown, as of 2018.<ref name=DautzenbergDautzenberg2018/> As a result of the various types of [[heat-not-burn product]]s, the characteristics and effects for each type will be different.

== Introduction ==

[[Heat-not-burn product|Heat-not-burn tobacco products]] are electronic devices that heat processed tobacco to supposedly deliver an aerosol with fewer toxicants than in cigarette smoke.<ref name=SimonaviciusMcNeill2018/> Commercially available heat-not-burn tobacco systems like glo (produced by [[British American Tobacco]] (BAT)) or [[heat-not-burn product#IQOS|IQOS]] ([[Philip Morris International]] (PMI)) include a charger, a holder and tobacco sticks, plugs or capsules.<ref name=SimonaviciusMcNeill2018/> Inserted into the holder, tobacco sticks are heated with an electronically controlled heating element.<ref name=SimonaviciusMcNeill2018/> Other products, like iFuse from BAT or Ploom Tech from [[Japan Tobacco]] (JT), produce aerosol from a non-tobacco source and pass it through a tobacco plug to absorb flavor and nicotine.<ref name=SimonaviciusMcNeill2018/> Heat-not-burn tobacco products aim for a niche between combustible tobacco smoking and [[electronic cigarettes]] that aerosolize nicotine suspended in humectants.<ref name=SimonaviciusMcNeill2018/>

Since the 1960s heat-not-burn tobacco products were in development by tobacco companies.<ref name=EliasDutra2018></ref> Safer heated tobacco products that deliver nicotine but limit emissions of [[tar (tobacco residue)|tar]] or [[carbon monoxide]] (CO) is a half-century old idea, which had been unsuccessfully market-tested since 1988, first as Premier by the [[R. J. Reynolds Tobacco Company|RJ Reynolds Tobacco Company]] (RJR) and later as Eclipse (RJR) and Accord (PMI).<ref name=SimonaviciusMcNeill2018/> As of 2018, various heat-not-burn products were reintroduced to the market.<ref name=StaalvandeNobelen2018></ref> Japan, where manufacturers have marketed several heat-not-burn brands since 2014, has been the focal national test market, with the intention of developing global marketing strategies.<ref name=ShiCaputi2017></ref> According to a 2018 report, the launching of the latest incarnation of heat-not-burn tobacco products is a reiteration of similar efforts in the past to use similar products to undermine [[tobacco control]], particularly efforts that present the tobacco industry as a [[harm reduction]] partner.<ref name=BialousGlantz2018></ref>

As of 2018, of the current heat-not-burn tobacco products, IQOS was launched in several cities in Japan, Italy and Switzerland in 2014, iFuse was released in Romania in 2015 and glo and Ploom Tech were introduced to Japanese cities in 2016.<ref name=SimonaviciusMcNeill2018/> Due to regulations restricting the sale of nicotine-containing e-cigarettes, Japan was a fertile market for heat-not-burn tobacco producers, suggesting that the products have potential 'for explosive global growth'.<ref name=SimonaviciusMcNeill2018/> By 2017, IQOS was available in 30 countries and was being considered by [[Food and Drug Administration|United States Food and Drug Administration]] for a [[modified risk tobacco product|reduced-risk product]] approval, and the UK was one of the first countries to assign a separate taxation category for heat-not-burn tobacco products.<ref name=SimonaviciusMcNeill2018></ref>
