Cytotoxic effect of e-liquids on HMEEC-1 cells according to CCK-8 analysis. (A) We assessed cell viability following exposure to tobacco-flavored e-liquid, menthol-flavored e-liquid, solvent (PG:VG = 5:5), and nicotine at different concentrations. (B) The IC50 values for each type of solution were 3.02 ± 0.16%, 1.62 ± 0.01%, 4.50 ± 0.14% and 0.07 ± 0.01 mg/mL, respectively, and these concentrations were used for further analysis (p < 0.05).
