THC Vaping Deaths: Latest Data and Key Facts
Public health agencies have documented hundreds of severe lung injury cases and dozens of deaths linked to vaping THC products, with the most notable surge occurring during the 2019 outbreak of e cigarette, or vaping, product use associated lung injury, known as EVALI.
