Important information about IQOS

PMI offers a variety of quality, scientifically substantiated smoke-free products that are better choices than continued smoking.

Our vision is that our smoke-free products will one day replace cigarettes.

  • 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.
  • 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 an alternative to quitting and are not designed for that purpose.
  • Minors should not use tobacco or nicotine in any form.
