For our second ever Open Science event, we decided to focus on one of the biggest problems with cigarettes: burning. It's the burning, or combustion, of tobacco that creates cigarette smoke and generates high levels of harmful chemicals. By heating instead of burning tobacco, we can avoid creating smoke and thus many of those harmful chemicals, and the levels of those chemicals that are present may be significantly reduced. This Open Science webinar will walk you through some of our most fundamental research on the aerosol of our leading heated tobacco product (HTP).

     

Cigarette smoke vs HTP aerosol

Many people believe that cigarette smoke and heated tobacco aerosol are the same, but they are not. In fact they are very different. Both fall under the category of aerosols, but how they are formed and what they're made of set them far apart from each other. Reducing and controlling the temperature is the key to avoid burning the tobacco, and thus to avoid creating smoke. Check out the information on this page and watch the webinar to learn more about the differences between cigarette smoke and heated tobacco aerosol.

Webinar and presentations

We hosted a webinar on September 15th, 2020, where our scientists walked the audience through our research on this topic in detail. Dr. Gizelle Baker, Director Global Scientific Engagement, hosted three sessions, each with a live Q&A. Here are our five presenters and their topics: 

  

What are the differences between smoke and aerosol?
Presented by Dr. Markus Nordlund, Lead Scientific & Medical Affairs

 

Why is the absence of combustion so important?
Presented by Dr. Tom McGrath, Global Head of Professional Channels

  

What do we know about the chemistry of IQOS aerosol?
Presented by Mark Bentley, Manager Project Management & Knowledge Integration

  

What is the impact of IQOS aerosol on indoor air?
Presented by Dr. Catherine Goujon, Manager Chemistry Research

 

What do we know from independent studies?
Presented by Dr. Maurice Smith, Senior Scientific Advisor

 

Reports: our research on HTP aerosol

Our scientists have studied the aerosol of our leading heated tobacco product in depth, comparing it against cigarette smoke at each step along the way. Those findings have been published in two reports already available on PMI Science.
