Vaping-Related Lung Illness: Updates


Colorado is one of multiple states investigating severe lung illness associated with vaping. While this investigation is ongoing and the definitive cause remains uncertain, people should consider not using vaping products.

What we know

  • While we can’t pinpoint the specific cause of these serious lung illnesses, we do know vaping products are poorly regulated and may contain or generate chemicals that are unsafe, potentially making people sick. 
  • No consistent vaping product, substance, or additive has been identified in all cases, nor has any single product or substance been conclusively linked to lung illness in patients. 
  • Vaping products contain more than just harmless water vapor. They are marketed as a “safe” alternative to smoking, but the long-term health effects of vaping are still unknown. If you're vaping to quit smoking, consult your doctor or call the Colorado QuitLine (1-800-QUIT-NOW) to get free FDA-approved treatments. 
  • Colorado currently has the highest nicotine vaping rates in the nation among teens.
  • With the large number of cases of lung illness we’re seeing nationally, it’s clear there are dangers associated with vaping.
