Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair offers a long-term record of drug and alcohol consumption by embedding biomarkers within the strands of growing hair. When collected near the scalp, hair samples can indicate drug and alcohol use over an approximate three-month period. Collecting hair is straightforward, resistant to tampering, and easy to send for testing.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (comparable to the diameter of a #2 pencil), yields about 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. It's recommended to assess the specimen's weight using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be taken. When discussing head hair, we mean scalp hair specifically. Body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial intake of a sample into a laboratory’s workflow. This stage involves checking that the sample is sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any necessary data entry not covered by an electronic chain of custody.
Screening provides an initial rapid assessment for drug substances. Although Screening is a cost-efficient method for negating drug presence in most samples, a positive screen requires confirmation to be valid in legal contexts. Samples that produce a presumptive positive in Screening mandate a follow-up confirmation test.
If presumptively positive at Screening, additional hair is extracted from the primary specimen for the Extraction phase. Here, drugs are isolated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug screening particularly challenging.
Positive screening outcomes are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with initial positive results are washed before confirmation if necessary. The end-to-end laboratory procedure from Accessioning to Confirmation undergoes review in line with the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

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. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
