Predicted E-Cigarette Initiation Rates under Different Lengths of Approval Delay. The default delay in the model is 2 years for each policy (referring to a 2-year delay in revoking existing e-liquid flavor bans; and a 1-year delay in approving an informational campaign followed by a 1-year delay in approving the budget for the campaign), which proceed in parallel. The default 2-year delay (solid blue line) is shown in comparison with scenarios in which each of these delays is halved (dashed red line) or doubled (dotted pink line)
