Hair analysis is now considered a potent means for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and substance use by storing biomarkers within the fibers of the growing hair. When a sample is taken near the scalp, it can reveal substance use over a window of nearly 3 months. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch lock comprising roughly 200 hair fibers (comparable in size to a #2 pencil) near the scalp yields 100mg of hair, the preferred amount for both screening and validation. For EtG, additional assessments, or panels exceeding 10, 150mg of hair is advised. It's advisable to measure the specimen using a jeweler's scale. If scalp hair cannot be obtained, a similar volume of body hair can be used. 'Head hair' refers exclusively to scalp hair in this context. 'Body hair' includes all non-scalp hair types, such as facial and axillary.
Process Overview
The lab processing of a drug test comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning means incorporating a sample into a laboratory's system initially. This step ensures the sample was securely sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and fills any missing data entry not available from an electronic chain of custody system.
Screening executes a quick preliminary check for drug presence. Though cost-effective for most samples, any positive screening results must be proven to be valid in legal settings. Presumptively positive samples from Screening need a follow-up confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is taken from the initial specimen for Extraction. During this stage, drugs get extracted from hair at significantly lower concentrations compared to other methods like urine or saliva, highlighting hair drug testing's complexity.
Confirmation for any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. Each step from Accessioning to Confirmation is scrutinized 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.
