Simulated Behavior Modes for Exclusive Cigarette and E-Cigarette Use, 2000–2019. After model calibration, simulations predict approximately exponential decline in established cigarette use (solid blue line), and exponential increase in established e-cigarette use (dot-dashed red line), between 2000 and 2019 [57]. No policy is implemented in this simulation. Note the different y-axis scales for each line
