Health Advisory: Severe Lung Injury Associated with Electronic Cigarette Product Use or Vaping
- MDHHS and Local Health Departments are investigating an outbreak of lung injury associated with electronic cigarette use, or vaping.
- Patients with e-cigarette, or vaping, product use-associated lung injury (EVALI) have been reported in every state, including Michigan.
- Most EVALI cases in Michigan and nationwide reported vaping THC (tetrahydrocannabinol) alone or in combination with nicotine.
- Laboratory data support previous findings that vitamin E acetate is closely associated with EVALI. Vitamin E acetate was identified in the bronchoalveolar lavage (BAL) fluid from a sample of EVALI patients but not in the BAL fluid from a healthy comparison group.
- FDA updated their information about vaping product testing on February. 12, 2020. Notably, 60.6% of the samples directly linked to confirmed or probable patients reported to CDC were found to contain THC, of which 50% were found to contain vitamin E acetate.
- While it appears that vitamin E acetate is associated with EVALI, there are many different substances and product sources that are being investigated, and there may be more than one cause.
- Michigan is working with the Centers for Disease Control and Prevention (CDC) and the federal Food and Drug Administration (FDA) on this investigation.
