No. A positive drug test shows that a drug or its metabolite was detected according to the testing method and applicable cutoff, but it does not by itself establish drug misuse or a substance use disorder. Depending on the specimen and substance involved, the result may also be insufficient to determine the amount used, exact time of use, or degree of impairment. Interpretation should consider the specimen type, collection timing, testing method, prescription history, clinical findings, and broader pattern of substance use.
Relevant information may include prescribed medications, dosage and refill history, treating-provider records, toxicology findings, emergency visits, reported patterns or routes of use, withdrawal symptoms, and treatment for substance-related problems. Prescription drug misuse generally includes taking medication in a dose, frequency, duration, or manner other than directed, using someone else’s prescription, or using a medication for a purpose other than prescribed.
Different specimen types provide different information about drug exposure. Urine generally has a longer detection window than oral fluid for many drugs, while oral fluid often reflects more recent exposure. Blood testing may be useful for acute or quantitative toxicology questions, while hair can provide information about exposure over a longer period but has different limitations concerning timing and interpretation. The meaning of any result depends on the substance, specimen type, collection timing, cutoff concentration, pattern of use, and analytical method, and no single result automatically establishes impairment.
No. Physical dependence, tolerance, and withdrawal can develop with repeated use of certain medications, including medications taken as prescribed, and do not by themselves establish misuse, addiction, or a substance use disorder. The broader clinical history may help distinguish physiological adaptation from a pattern involving impaired control, compulsive use, or continued use despite harmful consequences.

Testify in Court
Presents specialized findings and opinions clearly to judges, juries, arbitrators, or other decision-makers.
Separate toxicology or medical expertise may be appropriate when the central issues involve acute opioid toxicity, respiratory depression, naloxone administration, co-intoxicants, fentanyl concentrations, overdose treatment, or whether fentanyl caused or contributed to an injury or death. A response to naloxone may support the presence of opioid toxicity, but it does not identify fentanyl as the specific opioid responsible. Cases centered on a longer-term pattern of compulsive or problematic substance use may instead involve addiction medicine or other substance use disorder expertise.
