Absolute changes over time in systolic blood pressure (SBP) (A), diastolic blood pressure (DBP) (B), and heart rate (HR) (C) after acute nicotine-vaping (nicotine-session) (red triangles), acute nicotine-free-vaping (nicotine-free-session) (black squares), and acute sham-vaping (stop-session) (blue dots). In comparison to acute sham-vaping, acute nicotine-vaping increased SBP, DBP, and HR for 40, 30, and 60 min postexposure, respectively. In comparison to acute nicotine-free-vaping, acute nicotine-vaping increased SBP, DBP, and HR for 30, 30, and 60 min postexposure, respectively. The red asterisks represent significant P values from the comparison of acute nicotine-vaping vs. acute sham-vaping, the black asterisks represent significant P values from the comparison of acute nicotine-free-vaping vs. acute sham-vaping, and the gold asterisks represent significant P values from the comparison of acute nicotine- and nicotine-free-vaping. A mixed-effects linear model analysis was performed with experimental sessions and time points as fixed effects and baseline (BSL) values as random effects (random intercept model). *P < 0.05, **P < 0.01, ***P < 0.001. Data represent the mean ± SE.
