We assessed levels of 37 toxicants in aerosol emissions from conventional waterpipe heated with different charcoals and also with a heat management device (HMD), from the IQOS heated tobacco product (HTP), and the ‘OOKA’ electronic waterpipe. We also utilised literature data on toxicant yields in 3R4F reference cigarette smoke. When taking use patterns into account, toxicant yields were substantially lower in conventional waterpipe aerosol compared with cigarette smoke. Toxicant yields in electronic waterpipe aerosol were substantially lower than those in conventional waterpipe aerosol, both on a per session basis and when taking typical use patterns into account. Numerous toxicants in conventional waterpipe aerosol were absent in electronic waterpipe aerosol. In summary, during typical use conventional waterpipe emits fewer, and lower levels of, a number of toxicants relative to combustible cigarette smoke. In addition, electronically heating shisha further reduces toxicant levels, and many toxicants are absent in OOKA electronic waterpipe aerosol. These findings have important implications concerning toxicant exposure among waterpipe users, and for understanding how to potentially reduce health risks associated with waterpipe use.

A scoping review of behavioural studies on heated tobacco products / Ian M. Fearon (2024)

While this electrical heating causes the formation of an inhalable aerosol which contains nicotine, the aerosol from HTPs contains significantly fewer and lower levels of the harmful and potentially harmful chemicals found in cigarette smoke. As a result, HTP use potentially conveys reduced risks to health compared to cigarette smoking. While this relative reduction in individual health risk is becoming clearer, what is less certain is the impact of HTPs on overall population‑level health, taking into account both the potential positive impact on adult smokers who completely switch to using HTPs and any unintended impacts such as use by tobacco non‑users and particularly by youth. The aim of this scoping review was to collate and evaluate the published scientific evidence to date, with a cut‑off of 1 January 2024, investigating the impact of HTPs on population‑level health. This evaluation suggests that HTP use is almost exclusively observed among those with a history of cigarette smoking, and there is a growing body of evidence for the ability of HTPs to provide support for adult smokers to transition away from cigarette smoking, in the absence of any significant “gateway” into tobacco use initiation. Many studies have reported a significant degree of dual use of cigarettes and HTPs, and efforts to assess the reasons for such patterns of use, whether these provide overall exposure reductions, and whether dual use acts as a bridge towards a complete transition away from cigarette smoking, requires further investigation. In addition, correction of the widespread and increasing misperceptions of HTPs among adult smokers is recommended to promote HTP uptake as a potentially less harmful alternative to smoking in this population.

Tobacco-free nicotine pouches and their potential contribution to tobacco harm reduction / Erika Grandolfo (2024)  

Public Titre : Tobacco-free nicotine pouches and their potential contribution to tobacco harm reduction : a scoping review Type de document : document électronique Auteurs : Erika Grandolfo, Auteur ; Henry Ogden, Auteur ; Ian M. Fearon, Auteur Editeur : Springer Nature Année de publication : 2024 Collection : Cureus, ISSN 2168-8184 num. 16(2) Importance : p. 1-27 Présentation : ill., graph.; tab. Langues : Anglais (eng) Catégories : [TABAC] étude [TABAC] prévention:stratégie:réduction du risque [TABAC] sevrage tabagique Mots-clés : Pouche de nicotine Index. décimale : TA 5.8 Réduction des risques Résumé : Tobacco harm reduction (THR) refers to strategies designed to reduce the health risks associated with tobacco smoking but may involve continued use of nicotine and/or tobacco. Next-generation products (NGPs) are a THR alternative as they do not burn tobacco or produce smoke and deliver nicotine and have fewer and substantially lower levels of harmful chemicals compared to cigarettes. Tobacco‑free nicotine pouches (TFNPs) are an emerging category of nicotine‑containing oral products that do not combust or contain tobacco leaf. Similar to Swedish snus, TFNPs are placed between a user’s lip and gum, and nicotine is absorbed through the oral mucosa rather than being inhaled. The aim of this scoping review was to systematically collate and evaluate published scientific evidence (cut‑off of 31 May 2023) identified from bibliometric databases investigating the potential of TFNPs to contribute to THR. Overall, studies examining chemical constituents indicated that the use of TFNPs may result in lower exposure to toxicants than other tobacco or nicotine-containing products, both combustible and non‑combustible. This reduction in toxicant exposure has been demonstrated by multiple human biomarker studies and in vitro toxicological assessments to translate to harm reduction potential in smokers switching to TFNPs. However, further study is warranted. At present, there is some evidence from human behavioral research that TFNPs can support either transitioning away from smoking or reducing cigarette consumption. Furthermore, TFNP use appears very much limited to current users of traditional tobacco products, and youth uptake has been limited. In conclusion, the findings of this review indicate that TFNPs have the potential to support THR efforts and may help inform evidence‑based regulation.
