The examination of hair has emerged as an effective means for detecting the consumption of drugs and alcohol. Hair offers a long-term record of substance use by encapsulating biomarkers within the strands as they grow. When the hair is gathered near the scalp, it can reveal substance use for up to roughly a three-month duration. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A sample length of 1.5 inches, comprised of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp, yields approximately 100mg of hair, which is optimal for screening and verification. For tests involving EtG, additional panels, and beyond 10 drug panels, 150mg of hair is suggested. It's recommended to weigh the sample using a jeweler's scale. If scalp hair is not obtainable, the equivalent amount of body hair may be used. When referencing head hair, it pertains exclusively to scalp hair. Body hair covers all other types (such as facial, underarm, etc.).
Process Overview
The key stages in processing a drug test in a laboratory are: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory system. This stage involves confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drug abuse. Though cost-efficient for excluding drug use in most samples, a positive screening must be confirmed for legal admissibility. Samples that screen positive require secondary confirmation.
For samples showing positive indications in the Screening phase, additional hair is taken from the collected sample for the Extraction process. During this phase, drug components are isolated from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening exceptionally challenging.
Confirmation of a positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as potentially positive undergo necessary washing before confirmation. Every step of the laboratory process from Accessioning through Confirmation is verified in accordance with both the CAP (College of American Pathologists) Hair designation 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.
