Hair analysis is regarded as an effective instrument for identifying the consumption of drugs and alcohol. Hair offers a chronic timeline of alcohol and drug use by embedding biomarkers within the hair strand fibers as they grow. When obtained near the scalp, hair can offer a detection window of up to approximately 3 months for alcohol and other drugs. Hair collection is easy, somewhat resistant to tampering, and straightforward to transport.
A 1.5-inch portion consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and verification. For EtG, additional screenings, or tests beyond 10 panels, a 150mg sample is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair is not present, an equivalent volume of body hair may be gathered. When mentioning head hair, it refers solely to scalp hair. Body hair pertains to all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test follows four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a sample within a laboratory framework. This step includes ensuring the sample was sealed and sent correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening serves as a preliminary rapid assessment for drug abuse. Although Screening is a cost-efficient method to exclude drug use for most samples, any positive screen must be confirmed to gain court admissibility. Samples shown as presumptively positive in Screening require a secondary confirmation procedure.
Should a sample display presumptive positivity in the Screening phase, more hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are extracted from hair at concentrations significantly lower than those in alternative methods (e.g., urine or oral fluid), which is the reason hair drug screening is the most challenging methodology to execute.
Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab procedure from Accessioning through Confirmation is audited under both the College of American Pathologists (CAP) Hair guidelines and the ISO/IEC 17025 accreditation standards.

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.
