When i got tested they could see exactly what i took so they will see that what was in your system is not what you were being accused of taking. BUT without valid prescriptions for the medications it doesnt really matter, youre still abusing substances to them and for all they know you took it from someone else and they may investigate further. When I say they i mean your job will report you and the attorney general with investigate extensively into your documentation, pyxis record, mar, etc. Like they said dont talk to anyone, get a lawyer. That way maybe you can save yourself from getting any criminal charges.
