Metabolic capacity of pod-type ENDS aerosol exposed SAEC determined by MTS assay. After 24 h, the metabolic activity of SAEC exposed to JUUL Virginia Tobacco 5% aerosols was not significantly reduced at either of the puff fractions (1–50) and (101–150) (A). However, repeated exposure of 7 days elicited a significant reduction (*, p < 0.05) in cellular viability of 25% at 101–150 puffs as compared to the negative control (B).
