I took the test when i got charged for DUID, i did a feild test as well a urine test,i found out after that they can tell if u put water in it, (which i did put a little) that being can they tell how much water was added then minus it accordingly to find out the proper results? or will it mess up the results all together? I no drugs will still be present but does a urine test show possitive/negative, or is it accurate to say how much of a drug is in my system? and they cant tell exactly when the drugs were taken because they would show up in my system for atleast 3-4 days if not more.. right? and if they cant use my urine due to me putting water in it, are there consequences?
