Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and other substances by encasing markers in the structure of the developing hair strand. When collected near the scalp, it can offer a detection window for alcohol and other substances of up to three months. This method of collection is easy, somewhat resistant to tampering, and can be transported easily.
A 1.5-inch sample of roughly 200 hair strands (similar to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect quantity for primary testing and verification. With EtG, additional tests, and/or more than 10-panel tests, 150mg of the sample is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is not present, an equivalent quantity of body hair may be used. When discussing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four key phases in the laboratory handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of sample processing in a laboratory system. This step ensures that the sample was securely sealed and sent, assigns it a random LAN (Laboratory Accessioning Number), and completes any further data required outside an electronic custody chain system.
Screening provides an initial rapid assessment for substances of abuse. Screening is cost-efficient for ruling out drug use in most samples, but a positive finding requires further validation for legal admissibility. Samples testing positive in Screening mandate a secondary verification.
If a sample tests positive in Screening, more hair is extracted from the original specimen for the Extraction phase. Here, substances are isolated from hair at lower concentrations than in other methods (such as urine or saliva), hence why hair drug tests are challenging to perform.
Positive results from Screening proceed to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples undergo washing before confirmation as needed. Each laboratory phase from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
