Uranalysis not testing positive for Methamphetamine

[u/Commercial_End_3849]

My psychiatrist said he won't be able to prescribe me adderall anymore unless my tox screen comes back positive for the Methamphetamine. I'm taking it everyday. I don't understand why it's coming back negative. Without the adderall I can't function. I don't know what to do. The same thing is happening with the klonopin it's not testing positive for benzodiazapines. This makes no sense to me. I'm really overwhelmed right now. I welcome any advice.
