2017年12月，路透社發表了前員工指控PMI為獲得美國FDA產品核准而進行的[[臨床試驗]]中存在不法行為的相關證詞和文件，這份調查提到，PMI 正積極進行遊說，試圖阻撓或削減[[烟草控制框架公约|世界衛生組織菸草控制框架公約]]（FCTC）下制定的條款，此舉與公司聲稱支持無燃燒煙霧的未來的理念背道而馳。<ref name=":9">{{Cite news|last=Olivier|first=Wurlod|date=2017-07-15|title=Une enquête de Reuters fait tousser Philip Morris|language=fr|work=Tribune de Genève|url=https://www.tdg.ch/economie/entreprises/enquete-reuters-tousser-philip-morris/story/20777852|issn=1010-2248|accessdate=2023-09-19|archive-date=2021-12-13|archive-url=https://web.archive.org/web/20211213091608/https://www.tdg.ch/economie/entreprises/enquete-reuters-tousser-philip-morris/story/20777852|dead-url=no}}</ref><ref>{{Cite news|title=Scientists describe problems in Philip Morris e-cigarette experiments|language=en|work=Reuters|url=http://www.reuters.com/investigates/special-report/tobacco-iqos-science/|access-date=2021-12-05|archive-date=2022-10-01|archive-url=https://web.archive.org/web/20221001061519/https://www.reuters.com/investigates/special-report/tobacco-iqos-science/|dead-url=no}}</ref>

2020年的文獻回顾建議，應針對IQOS對於吸菸者健康的影響進行更進一步的研究，因為現有科學文獻有關該主題的探討非常有限。部份第三方毒性研究的結果也與PMI的結果互相牴觸。<ref>{{Cite web|date=2018-08-30|title=Two more peer reviewed papers find that PMI's own data shows IQOS is more dangerous than PMI claims, likely as bad as cigarettes|url=https://tobacco.ucsf.edu/two-more-peer-reviewed-papers-find-pmi%27s-own-data-shows-iqos-more-dangerous-pmi-claims-likely-bad-cigarettes|access-date=2021-12-05|website=Center for Tobacco Control Research and Education|language=en|archive-date=2022-09-28|archive-url=https://web.archive.org/web/20220928095456/https://tobacco.ucsf.edu/two-more-peer-reviewed-papers-find-pmi%27s-own-data-shows-iqos-more-dangerous-pmi-claims-likely-bad-cigarettes|dead-url=yes}}</ref><ref>{{Cite journal|last=Glantz|first=Stanton A.|date=2018-08-21|title=PMI's own in vivo clinical data on biomarkers of potential harm in Americans show that IQOS is not detectably different from conventional cigarettes|journal=Tobacco Control|volume=27|issue=Suppl 1|pages=s9–s12|doi=10.1136/tobaccocontrol-2018-054413|issn=1468-3318|pmc=6202159|pmid=30131374}}</ref><ref name="未命名-20251117145617"/>

2018年10月，比利時癌症基金會根據先前就IOQS發表的獨立研究提出了建議，該基金會表示「 不應把IQOS當成戒菸的解決方案 」，同时進一步指出「如果菸草巨擘是為了補足傳統式燃燒紙菸銷售額減少的缺口，才投入這個創新市場，那麼它只是替自己找了個留住既有成癮消費者以確保能持續獲利的解套方案。」。<ref name=":10">{{Cite web|title=IQOS : aussi nocif que la cigarette|url=https://www.cancer.be/nouvelles/iqos-aussi-nocif-que-la-cigarette|access-date=2021-12-05|website=www.cancer.be|language=fr|archive-date=2022-09-30|archive-url=https://web.archive.org/web/20220930120402/https://www.cancer.be/nouvelles/iqos-aussi-nocif-que-la-cigarette|dead-url=no}}</ref>

2020年7月，[[世界卫生组织|WHO]] 世界衛生組織針對加熱菸草產品（HTP）及美國FDA有關IQOS的決定發表了聲明，重申加熱菸草產品（HTP）雖能減少有害化學物質接觸，但並不會因此使它們變得毫無健康危害，也不能解讀為能降低對人體健康的風險。事實上，有些有害物質在加熱菸草產品（HTP）氣霧中的含量反而高於傳統燃燒式紙菸的煙霧，而且，加熱菸草產品（HTP）氣霧中也存在著一些傳統燃燒式紙菸菸霧中不存在的毒素。有鑑於接觸於這些物質下對人體健康的影響尚不可知，宣稱相較於傳統燃燒式紙菸，加熱菸草產品（HTP）能減少人體接觸有害化學物質的說法可能具有誤導性。<ref name=":8"/>

[[巴斯大學]]的TobaccoTactics 網站寫道：「很少證據顯示IQOS能作為有效戒除傳統燃燒式紙菸的工具。」。[[荷蘭國家公共衛生及環境研究院|荷蘭國家公共衛生與環境研究所]]則表示：「IQOS會對人體產生危害，但可能相較於傳統燃燒式紙菸少。」。<ref>{{Cite web|title=PMI's IQOS: Use, "Switching" and "Quitting" - TobaccoTactics|url=https://tobaccotactics.org/wiki/iqos-use/|access-date=2021-12-05|website=tobaccotactics.org|language=en|archive-date=2022-01-29|archive-url=https://web.archive.org/web/20220129021557/https://tobaccotactics.org/wiki/iqos-use/|dead-url=no}}</ref><ref>{{Cite web|title=Addictive nicotine and harmful substances also present in heated tobacco|url=https://www.rivm.nl/en/news/addictive-nicotine-and-harmful-substances-also-present-in-heated-tobacco|access-date=2021-12-05|website=www.rivm.nl|archive-date=2022-10-06|archive-url=https://web.archive.org/web/20221006110130/http://www.rivm.nl/en/news/addictive-nicotine-and-harmful-substances-also-present-in-heated-tobacco|dead-url=no}}</ref>

針對R.J.Reynolds所提出的專利侵權訴訟案，[[美国国际贸易委员会|美國國際貿易委員會]]認定IQOS侵犯了原告的兩項專利，因此在 2021 年 9 月裁定 PM USA 及其商業夥伴 Altria 禁止將 IQOS 裝置進口到美國甚或是進行銷售。對此，PM USA宣佈將對該貿易機構的決定提出上訴。<ref>{{Cite web|last=Lucas|first=Amelia|date=2021-09-30|title=Philip Morris, Altria banned from importing or selling Iqos tobacco device in the U.S.|url=https://www.cnbc.com/2021/09/30/philip-morris-altria-banned-from-selling-iqos-tobacco-device-in-the-us.html|access-date=2021-12-05|website=CNBC|language=en|archive-date=2022-09-30|archive-url=https://web.archive.org/web/20220930120402/https://www.cnbc.com/2021/09/30/philip-morris-altria-banned-from-selling-iqos-tobacco-device-in-the-us.html|dead-url=no}}</ref><ref>{{Cite news|last=Maloney|first=Jennifer|date=2021-09-30|title=U.S. Trade Body Rules Against Import of IQOS Heat-Not-Burn Tobacco Devices|language=en-US|work=Wall Street Journal|url=https://www.wsj.com/articles/u-s-trade-body-rules-against-import-of-iqos-heat-not-burn-tobacco-devices-11632966156|issn=0099-9660|accessdate=2023-09-19|archive-date=2022-10-01|archive-url=https://web.archive.org/web/20221001112424/https://www.wsj.com/articles/u-s-trade-body-rules-against-import-of-iqos-heat-not-burn-tobacco-devices-11632966156|dead-url=no}}</ref><ref name="未命名_2-20251117145617">{{Cite web |url=https://tobaccoreporter.com/2024/04/01/turning-up-the-heat-4/ |title=Turning Up the Heat |website=Tobacco Reporter |date=2024-04-01}}</ref>2024年2月，PMI与英美烟草公司（BAT）达成无金钱赔偿的和解协议，结束了双方就加热烟草产品和电子烟产品展开的的专利侵权诉讼案<ref name="未命名_2-20251117145617"/>。
