Policy Simulations of Predicted E-Cigarette Initiation Rates under Ideal Case versus Practical Limitations. The ideal case (solid blue line) is contrasted with policies with time delays in implementation, alone (dot-dashed red line), with uncertain approval for removing e-liquid flavor bans (dotted green line), with reduced budget for informational campaigns promoting e-cigarettes as a less harmful alternative (dot-dashed cyan line), and with both uncertain approval and reduced budget (solid orange line)
