Tobacco and Nicotine

  • Tobacco units used with IQOSTM devices, 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 tobacco units, 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 units

  • Only use IQOS 3 DUOTM or earlier generation devices with tobacco units. Never use IQOS devices with a cigarette or similar products. Doing so may cause injury.
  • Do not modify tobacco units in any way or add any substance to themDoing so may result in injury.

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.
