Vaping flavors and devices both appear to affect gene activity linked to disease
Coverage of a 2026 study reporting that e-cigarette flavoring and device type are each associated with changes in gene-expression patterns connected to disease risk.
A team of researchers examined how different e-cigarette flavors and device configurations correlate with shifts in gene-expression patterns in users. The reporting summarizes the authors' conclusion that both the chemical flavoring profile and the hardware (coil, power, aerosol output) appear to be independent variables — not just nicotine concentration.
