Hair testing has emerged as an effective method for identifying drug and alcohol use. Hair can offer a prolonged history of alcohol and drug use by capturing biomarkers within the strands of hair as it grows. Collected near the scalp, hair can offer a detection window of up to roughly three months for alcohol and drugs. Hair is straightforward to collect, somewhat challenging to tamper with, and simple to transport.
A sample of 1.5 inches, consisting of about 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp, will provide 100mg, which is the ideal size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, it is recommended to use 150mg of the sample. We suggest using a jeweler’s scale for the specimen’s weight. If hair from the scalp is not accessible, a comparable quantity of body hair can be used. When mentioning head hair, it strictly pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four primary steps in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample within the laboratory’s system. This step includes verifying that the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.
Screening entails an initial swift check for drug abuse. While Screening is a cost-effective measure to eliminate drug use from most samples, a positive screen necessitates confirmation to be acceptable in court. Any samples showing presumptive positive results in Screening require a subsequent confirmation.
If a sample shows presumptive positive results during Screening, additional hair is pulled from the original specimen and prepared for Extraction. At this stage, drugs are extracted from hair in much lower amounts than through other means (e.g., urine or oral fluids), making hair drug screening one of the most complex methodologies to perform.
Confirmation of any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are washed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards 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. 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.
