Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair retains a long-standing record of alcohol and drug use by embedding biomarkers within the strands as they grow. When samples are taken close to the scalp, hair can provide approximately a 3-month timeframe for detecting alcohol and drugs. Hair is easy to collect, relatively tamper-proof, and straightforward to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the ideal quantity for analysis and verification. For EtG, additional tests, and/or beyond 10-panel tests, a sample of 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen accurately. If head hair is not an option, a similar volume of body hair can be used. When mentioning head hair, it specifically denotes scalp hair only. Body hair includes all other hair varieties (facial, axillary, etc.).
Process Overview
The primary steps in the lab handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the sample's initial integration into a lab’s system. This step involves confirming the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry absent from the electronic chain of custody system.
Screening comprises a preliminary drug abuse check. While Screening is an economical means to rule out drug presence in most samples, any positive result requires confirmation for legal acceptability. Samples showing presumptive positive results in Screening necessitate follow-up confirmation.
For presumptive positives in Screening, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are retrieved from hair at significantly lower concentrations than in other approaches (e.g., urine or oral fluid), making hair drug testing the most complex to execute.
Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as necessary. The entire procedure from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair protocol and the 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.
