Of these, 29 percent were drug positive compared to the 14 percent who were drugpositive <strong>and</strong> indicated “No” (p < .01).Additionally, since the nighttime results are quite similar, whether summarized <strong>by</strong> oral fluidresults or blood results, we are presenting these tables on contact with the criminal justice systembased on nighttime blood results in Appendix A.Table 60.
