I've heard about a new e-cigarette product. What is it and is it safe?

The new electronic cigarette is called the IQOS, which stands for "innovative quotient" and was developed by Philip Morris International (PMI). It is designed to heat tobacco instead of burning it like traditional cigarettes, so that users get the nicotine they need without all the harmful chemicals. PMI claims that this technology makes the IQOS safer than regular cigarettes because it reduces exposure to toxins, but some experts disagree. They say there are still concerns about how much nicotine users will get from the device, as well as the potential risks associated with inhaling aerosolized propylene glycol and glycerin.
