Hair Analysis for Drugs of Abuse: Plausibility of Interpretation

Hair analysis for drugs of abuse was increasingly recognized in various fields such as employment screening, forensic science, and clinical diagnostics. It provided valuable information for evaluating chronic drug use, poisoning, and exposure to pollutants. Hair's unique properties allowed for retrospective investigation, even detecting single doses with ultrasensitive methods. However, the complexity of hair growth and drug incorporation, along with variations in laboratory practices, posed challenges. Accurate interpretation required understanding these complexities and considering case-specific circumstances to avoid pitfalls and ensure responsible results.
