Notes: All models include quarter and year fixed effects. Individual and county level variables are also included (see notes under Table 3) and the same reference categories apply as in Table 3. Column 4 does not include 1,000 observations from Arizona and 662 observations from states that do not have a maximum fine for possessing 10 grams. The sample size decreases by 1,791 observations in Columns 5–7 because enforcement data are limited to jurisdictions with UCR Coverage Indicator scores >=70. Standard errors clustered at the state-level in all models. Statistical significance using a two-tailed test is indicated as follows:

significant at 10%;

^**

significant at 5%;

significant at 1%.
