UC Davis Study Finds Disposable Vapes Contain Toxic Metals Exceeding Cigarette Levels

A series of studies from the University of California, Davis have revealed that disposable vapes, particularly popular but unauthorized brands like ELF Bar, Esco Bar, and Flum Pebble, contain toxic metals such as lead, nickel, and antimony at levels exceeding those found in traditional cigarettes. One key finding is that the lead exposure from just one day of vaping can be equivalent to smoking 19 packs of cigarettes, raising significant health concerns, especially for teenagers and young adults who frequently use these products. These metals originate from leaded bronze components and degraded heating coils in the devices, which leach into the e-liquid and are inhaled directly into the lungs, increasing risks of cancer, neurological damage, respiratory disease, and heart problems. The studies emphasize that these disposable vapes are often unregulated and illegal, yet remain widely accessible, highlighting a public health crisis intensified by flavored products targeting youth. Experts warn that while vaping is sometimes promoted as a less harmful alternative to combustible tobacco, these findings challenge that notion for disposable devices, underscoring the urgent need for stricter enforcement and regulation. The health impacts also extend beyond cancer risk, with toxic metals potentially linked to mental health issues and gastrointestinal problems.
