CDC, the U.S. Food and Drug Administration (FDA), state and local health departments, and other clinical and public health partners are investigating a multistate outbreak of lung injury associated with use of e-cigarette, or vaping, products.

What CDC Recommends

  • While this investigation is ongoing, CDC recommends that you consider refraining from using e-cigarette, or vaping, products, particularly those containing THC.
  • If you are an adult who used e-cigarettes containing nicotine to quit cigarette smoking, do not return to smoking cigarettes. 
  • If you have recently used an e-cigarette or vaping product and you have symptoms like those reported in the outbreak, see a healthcare provider. 
  • Regardless of the ongoing investigation: 
    • Anyone who uses e-cigarette, or vaping, products should not buy these products (e.g., e-cigarette or vaping products with THC or CBD oils) from informal sources (e.g., friends, family members) or "off the street," and should not modify or add any substances to these products that are not intended by the manufacturer. 
    • Youth and young adults should not use e-cigarette, or vaping, products. 
    • Adults who do not currently use tobacco products should not start using e-cigarette, or vaping, products. 
    • THC use has been associated with a wide range of health effects, particularly with prolonged heavy use. The best way to avoid potentially harmful effects is to not use THC, including through e-cigarette, or vaping, products. Persons with marijuana use disorder should seek evidence-based treatment by a health care provider.
