"Using the above model of evaluation it can be seen that the DrugWipe 5 delivers the best results for sensitivity (91%) whilst also performing very highly in terms of specificity (95%). However the margins of error (95% confidence interval) displayed in Figure 43 show that this value could vary between 78-97%, this margin of error would seem to be due to the size of the study population (135 tests performed) since the device was only tested in Finland. The strong results for this device probably reflect largely on the device?s high performing individual amphetamines test in a country with a relatively high prevalence for amphetamines. However, this overall sensitivity is still higher than the individual sensitivity of the amphetamines test for DrugWipe 5 (87%) indicating that the device was successful in screening for other drugs. Both DrugTest 5000 and Rapid STAT also performed strongly in this evaluation both for sensitivity (85% and 82% respectively) and specificity (86% and 88% respectively), which is a reflection of their generally relatively good performance for each individual substance test. The sensitivity error margins are also somewhat narrower for these two devices that were tested on a greater number of subjects (220 and 342 tests performed respectively). The OrAlert device also performs at a high level of sensitivity (81%) in this evaluation, however the specificity is somewhat lower at 70% - which is the lowest score for any of the devices. The sensitivities of the other four devices included in the study range between 64% and 32%, which are quite low values. The specificities are, however, very high, or excellent, at between 93% and 100%. The relatively large error bars for the Oratect III device and BIOSENS can be attributed to the number of successful evaluations (58 and 25 respectively)."

If lawmakers are truly concerned about substance abuse among welfare recipients, there are more effective options than drug testing. Most states already have requirements for people on TANF to participate in substance abuse treatment programs if that’s identified as a barrier to their employment. “The sponsors [of drug testing bills] often don’t know what the state actually already does,” Schott said. “If that’s your goal, then why don’t you look at what you’ve got, maybe put some funding into making those programs available, maybe allow participation and treatment to count toward work requirements.”
