Puff Topography and Sensory Effects Across IQOS Device Generations

29. juli 2026 opdateret af: American University of Beirut Medical Center

Puff Topography and Sensory Effects Across IQOS Device Generations: A Randomized Crossover Study

The goal of this clinical trial is to learn how people use two generations of IQOS heated tobacco devices and how each device affects their smoking behavior and sensory experience.

The main questions it aims to answer are:

  • Do participants puff differently when using the newer IQOS Iluma i compared to the older IQOS 2.4?
  • Does the flavor of the tobacco stick (preferred flavor vs. standard tobacco flavor) affect puffing behavior or sensory experience?
  • What are the differences in throat hit, mouthfeel, and satisfaction between the two devices?

Participants will:

  • Attend 2 laboratory visits at the American University of Beirut
  • Use both the IQOS Iluma i and IQOS 2.4 devices during each visit
  • Have their puffing behavior recorded automatically during device use
  • Provide a breath sample before and after each use session
  • Complete short questionnaires about how each device felt and their urge to smoke

Detaljeret beskrivelse

Heated tobacco products (HTPs) such as IQOS have evolved across generations, with newer models using induction-based heating rather than a ceramic blade. Nicotine yields have declined across generations, raising the possibility that sensory characteristics have been modified to maintain product appeal. Current emissions assessments rely on standardized machine-puffing regimens derived from cigarette testing, which may not reflect real-world IQOS user behavior. This study will characterize puff topography (volume, duration, flow rate, inter-puff interval, number of puffs) in 50 exclusive IQOS users during ad-libitum use of the IQOS Iluma i and IQOS 2.4 under preferred and standardized (Amber) flavor conditions. A randomized crossover design with two visits will be used, with device order within each visit randomized using a Williams design. Secondary outcomes include chemosensory ratings (mouthfeel, ease of draw, throat hit), and subjective effects (satisfaction, pleasantness, taste, urges). Data will inform device-specific puffing regimens for use in future emissions assessments.
