Important information about IQOS


Information that you should know about IQOS:

  • Cigarette smoking causes serious diseases and is addictive. Without question, the best decision any smoker can make is to quit tobacco and nicotine use altogether.
  • Minors should not use tobacco or nicotine in any form.
  • PMI’s smoke-free products are for adults who would otherwise continue to smoke or use other nicotine products.
  • We do not offer PMI’s smoke-free products to people who have never used tobacco or nicotine products or who have quit using tobacco and nicotine products. Our smoke-free products are not alternatives to quitting and are not designed as cessation aids.
  • PMI’s smoke-free products are not risk free and contain nicotine, which is addictive. Switching to a smoke-free product is, however, a better choice than continuing to smoke.
  • We support our adult smoke-free product users in their journey to full conversion through education and guidance.
  • For consumers to experience the benefits of smoke-free products, they must switch completely and abandon smoking permanently.
  • We inform consumers of all relevant safety information about our smoke-free products.

    Tobacco and Nicotine

  • Tobacco sticks used with IQOS contain nicotine, which is addictive.
  • IQOS is not risk-free. The best way to reduce tobacco- and nicotine-related health risks is to quit tobacco and nicotine use altogether.
  • Some users of nicotine-containing products may experience abdominal pain, chest pain, choking sensation, cough, difficulty breathing, dizziness, dry mouth, dry throat, gingivitis, headache, malaise, nasal stuffiness, nausea, mouth irritation, palpitations, throat irritation, and vomiting.
  • Nicotine-containing products should not be used by people who have or are at risk of heart disease, are diabetic, are epileptic, or are experiencing seizures.
  • Nicotine-containing products should not be used during pregnancy or while breast-feeding. If you are pregnant, breast-feeding, or think you may be pregnant, you should quit tobacco and nicotine use altogether.
  • Stopping smoking or switching to IQOS and its respective tobacco sticks, or other nicotine-containing products may require the adjustment of the dosing of certain medicines (e.g. theophylline, clozapine, ropinirole).
  • If you have questions about whether you should use IQOS given an existing health condition, consult a health care professional.

  • Use of tobacco sticks

  • Only use:
  • IQOS 3 DUO or earlier generation devices with tobacco sticks designed to be used with it.
    Never use IQOS devices with a cigarette or similar products. Doing so may cause injury.
  • Do not modify tobacco sticks in any way or add any substance to them. Doing so may result in injury.

  • Prior to use of a product, users should read the full Safety Warnings & Instructions, which contain important safety information about the use of the product.

    Battery Degradation

    IQOS devices, including holders, contain a lithium-ion battery. The lithium-ion battery in the devices is a consumable component that degrades with usage and age. This is a natural process common to all rechargeable lithium-ion batteries. As the battery ages, the active ingredients inside the battery become less capable of retaining energy, resulting in a permanent decrease in maximum battery capacity and usable energy. In addition, the active ingredients become less effective in delivering energy, resulting in a decrease of the battery’s ability to provide sufficient power for electronic device components to operate. As a result, where relevant, the duration of experience may appear to be shorter, the number of puffs or experiences with one full charge may appear to be fewer, the second consecutive use might be shorter or missing.

    The battery is a chemical system that requires certain temperature ranges during charge and discharge to work optimally and minimize battery capacity degradation over its lifetime. Although your device has a specific operating range within which the device will function, operating at the extreme ends of this range will degrade your battery faster. Your device comes with customized software to control the charging parameters in order to maximize the life of your device. These algorithms can support the longevity of your battery life, but they can still never fully mitigate the normal aging mechanisms of lithium batteries. High and low temperature operation of your device will accelerate the natural degradation of your battery. Even if you do not use your device the batteries contain chemical systems which can still degrade over time. In order to slow the battery degradation process, we recommend charging your device within the recommended temperature zone, not keeping it discharged for long periods of time and using the charging cables and power adaptors that come together with the device as per the user guides.

    You will find consumer communication around the website that come from the following sources:

    Studies* showed that the satisfaction of those who switched completely to IQOS is comparable to those who continued to smoke cigarettes.
    * Source: 3 month clinical studies conducted in US and Japan with 160 adult smokers each under real conditions (ambulatory).


    IQOS leaves significantly less stains on your teeth* than cigarettes. Important information:  If teeth are already stained, switching to IQOS will not reverse the colour of those stains.
    * Source: non-clinical laboratory study conducted in Switzerland with human teeth and the most widely used dental composites. Contrary to real world conditions, teeth were not exposed to other staining substances such as coffee, tea or wine, which may influence the results.


    Smokers who switched to IQOS say that there is less unpleasant feeling and aftertaste left in their mouth compared to after finishing smoking a cigarette*
    * Source: Online survey conducted by third-party research agencies in 2015, 2016 and 2017 among 3.344 IQOS users in Japan, Switzerland, Italy, Romania and Russia.


    IQOS has no negative impact on indoor air quality.*
    *Source: PMI study conducted under ISO standards simulating real-world scenarios and based on threshold limits established by existing air quality guidelines.


    Switching completely to IQOS presents less risk to your health than continuing to smoke. IQOS emits 95% less harmful chemicals compared to cigarettes.*
    * ”95% less” represents the average reductions in levels of a range of harmful chemicals (excluding nicotine) compared to the smoke of a reference cigarette. It does not necessarily equal a 95% reduction in risk. See Important Information on IQOS.com


    IQOS has extensive and robust clinical evidence* showing that using IQOS presents less risk to your health than continuing to smoke.
    * Source: Based on the totality of evidence available for IQOS in comparison with continuing to smoke.
