Many of the Detox drinks are just diluting your sample which on its own is a fail. If you get it just right it might work but it's no gurentee. The test is looking at your creatine levels which will not be high if you drank a lot before. So in theory with vitamin B to color the sample and creatine supplements you might me able to do the old dilution trick. Pr-employment tests are not as sensitive as probation tests.
Don't give the beginning or end of the stream the concentrations of THC are higher here. But unless someone watches you pee this is no problem. If you did stop for a while green tea is a good way to burn off the THC.
