Secondhand Smoke and Cystic Fibrosis (CF)

Secondhand smoke is what you breathe in when you are around a smoker. It’s the smoke from the burning end of a cigarette, vape pen, cigar, pipe, or a smoker’s mouth. Smoke has many poisons and irritants. It hurts everyone, but it hurts babies and young children more. This is because they breathe faster, so they’re breathing in even more poisons than adults. Children can’t leave a room when the air is smoky. They depend on us to make sure they have clean air. Secondhand smoke is very dangerous for children with CF.

What Is Secondhand Smoke

  • Secondhand smoke contains:
  • Carcinogens - These are chemicals that cause cancer. Secondhand smoke contains at least 69 carcinogens.

  • Oxidants - These hurt the heart and blood vessels.

Problems With Secondhand Smoke and CF

  • It can reduce lung function and make breathing harder.
  • It can make them have more lung and sinus bacterial infections.
