Hair analysis is recognized as an effective method for detecting drug and alcohol use. Hair can record a lengthy history of substance consumption by capturing biomarkers within the strands of growing hair. When taken close to the scalp, hair may offer up to around a 3-month timeframe for detection of alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and straightforward to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a 150mg sample is advised. It's preferable to weigh the sample using a jeweler’s scale. If scalp hair cannot be accessed, a comparable quantity of body hair can be utilized. Head hair denotes scalp hair exclusively, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with initial processing of a sample into the lab’s system. This step ensures the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary additional data entry missing from an electronic chain of custody system.
Screening entails a quick preliminary check for drug abuse. While Screening is cost-effective for dismissing drug use in most samples, a positive screen must be confirmed for court admissibility. Any samples with a presumptive positive in Screening require follow-up confirmation.
Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the sample for the Extraction phase. Drugs are isolated from the hair at a much lower concentration than in other methods (such as urine or oral fluid), making hair drug screening among the most complex methods to conduct.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed prior to confirmation if necessary. The entire lab process from Accessioning to Confirmation is evaluated following both the CAP (College of American Pathologists) Hair standards 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.
