Hair analysis is widely recognized as an effective method for identifying drug and alcohol consumption. The fibers of the hair strand capture biomarkers, providing a long-term record of substance use. Collected near the scalp, hair can offer a detection timeframe of up to three months for alcohol and drugs. Collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch hair sample, approximately 200 strands (around the size of a #2 pencil) closest to the scalp, yields 100mg of hair, the optimal sample for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to weigh the specimen using a jeweler’s scale. If scalp hair is unattainable, a corresponding quantity of body hair can be collected. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The lab process for drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent in an electronic chain of custody system.
Screening conducts an initial evaluation for substance use. Though cost-efficient for excluding drug usage in most cases, a positive screen requires confirmation to be legally valid. Samples presumptively positive in Screening must undergo secondary confirmation.
If positive in the Screening phase, further hair is extracted from the original specimen for Extraction. This stage removes drugs from the hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Positive screening results go through Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are washed before confirmation as necessary. The complete process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 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.
