- The CDC is investigating 193 potential cases of severe lung disease linked to e-cigarette products (vaping), reported between June 28 and August 20.
- The CDC is working with 22 states to investigate the cause and to determine whether any specific products are implicated. The investigation began in Wisconsin and Illinois.
- The FDA has joined the investigation, encouraging physicians and the public to submit details of any unexpected tobacco- or e-cigarette-related health problems or product concerns to the FDA safety portal for tobacco products.
Why this matters
- If vaping turns out to be the cause, the FDA may take action to remove products from the market or control who can buy e-cigarettes.
- Infectious disease has been ruled out as the principal cause.
- One death has been reported.
- The CDC refers to the condition as "a cluster of pulmonary illnesses possibly related to vaping."
- In many cases, the pulmonary disease begins gradually, with breathing difficulty, shortness of breath, and/or chest pain, before worsening that requires hospitalization.
- Some patients report mild to moderate gastrointestinal illness with vomiting, diarrhea, and fatigue.
- Many patients report recent use of tetrahydrocannabinol-containing products, but no individual product has been implicated across all cases.
- Although the cause is unknown, all reported cases involve vaping.
