DUID
Providing defense and clarity on drugs/medications as conclusive evidence
DWI
Identifying conditions with symptoms indistinguishable from those induced by alcohol and/or drugs
Refusal
Explaining suspect's Refusal to Submit Samples of Breath involving mental health or medical conditions
Impairment Consultants, LLC delivers expert evaluation and testimony in DWI, Refusal, and DUID cases. Led by Brett J. Murphy, APN, PMHNP-BC, we review case discovery, clinical test results, and medical history to identify whether medical or mental health conditions may explain signs that appear to mimic impairment. Our goal: to provide clarity, context, and defensible analysis for legal teams.
