Hair testing is increasingly viewed as an effective instrument for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug intake by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, it can reveal alcohol and drug use for a period of up to about three months. Hair collection is straightforward, somewhat resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches and consisting of approximately 200 hairs (akin to the size of a #2 pencil) near the scalp will yield 100mg, which is the optimal sample for examination and validation. For EtG, additional tests, or tests exceeding ten panels, a specimen weight of 150mg is suggested. It’s advisable to weigh the specimen using a jeweler’s scale. If scalp hair isn’t available, a proportional amount of body hair can be collected. References to head hair specifically mean scalp hair. Meanwhile, body hair refers to all other types (such as facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into the lab’s system. This step includes confirming that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing necessary data entry not included in an electronic chain of custody system.
Screening entails an initial rapid assessment for substances of abuse. While Screening is a budget-friendly method to eliminate drug usage in most samples, a positive result must be confirmed for it to be legally valid. Samples that test presumptive positive during Screening need further confirmation.
If the Screening stage indicates a presumptive positive, more hair is extracted from the original sample and set for Extraction. This step involves removing drugs from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluids), which is why hair drug screening is among the hardest methodologies to execute.
Confirmation for any positive Screening result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation as required. The full laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation 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.
