Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair serves as a long-term record for alcohol and other substances by capturing biomarkers within the fibers of the developing hair. When collected close to the scalp, a hair sample can offer up to about a 3-month window for identifying alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.
An ideal hair sample for screening and confirmation involves a 1.5-inch segment of roughly 200 hair strands (approximately the diameter of a #2 pencil) taken near the scalp, providing 100mg of hair. For EtG, additional tests, and/or panels beyond 10, a sample of 150mg is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be used. Head hair references scalp hair exclusively, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
Four key steps make up the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab’s system, ensuring it was properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening is a preliminary check for abuse substances. Although Screening is an economical method to eliminate drug use in most samples, any positive screen must be verified for court admissibility. Samples with presumptive positives in Screening require a secondary confirmation.
Presumptive positives in the Screening phase prompt additional hair extraction from the original sample for preparation for Extraction. Drugs are extracted from hair at much lower concentrations compared to other methods (urine or oral fluid), making hair drug screening the most challenging methodology.
Positive screening confirmations are made through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. From Accessioning through Confirmation, the full lab process is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
