Hair samples have emerged as a robust method for identifying alcohol and drug usage. Hair retains an extended record of substance intake by embedding biomarkers within the strands. When taken from near the scalp, hair can offer a detection period of around 3 months for alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
A 1.5-inch segment comprising roughly 200 hair strands (approximately the size of a #2 pencil) from the scalp provides 100mg of hair, the optimal quantity for screening and validation. For EtG, additional testing, and panels exceeding 10, a 150mg sample is advisable. We suggest using a jeweler’s scale for measurement. If head hair is inaccessible, an equivalent volume of body hair may be utilized. "Head hair" refers exclusively to scalp hair, whereas "body hair" refers to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug tests encompasses four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initial integration of a sample into the lab’s framework. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry if not handled by an electronic chain of custody system.
Screening involves a preliminary evaluation for drugs of abuse. While Screening efficiently excludes drug use in most samples, a positive result necessitates confirmation for legal admissibility. Samples showing presumptive positives in Screening require further confirmation.
Should a sample yield a presumptive positive during Screening, additional hair is extracted from the primary sample for the Extraction stage. Here, drugs are drawn from hair at far lower concentrations than other mediums (e.g., urine or oral fluid), establishing hair drug screening as the most challenging technique.
Confirmation of any positive screen result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly referred to as "hair follicle tests", the examination actually targets the hair strand rather than the follicle under the scalp.

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.
