Hair drug testing is now widely recognized as a potent method for detecting drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the strands as they grow. When collected near the scalp, this method offers approximately a 90-day detection period for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to send.
A hair sample measuring 1.5 inches with around 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg—ideal for both screening and confirmation. For tests such as EtG, add-ons, and those beyond 10 panels, a 150mg sample is suggested. It's advisable to weigh the hair on a jeweler's scale. If scalp hair isn't available, an equal quantity of body hair can be used. When we refer to head hair, it means scalp hair specifically. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of drug testing encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial entry of a sample into a lab's system. This step ensures the sample is sealed and shipped accurately, assigns a random Laboratory Accessioning Number (LAN), and completes any data entry absent from an electronic chain of custody system.
Screening acts as a preliminary assessment for drug abuse. Though Screening efficiently rules out drug use for most samples, a confirmed result is necessary for legal admissibility. Thus, presumptive positive findings in Screening require additional confirmation.
Should a sample register positive during Screening, extra hair from the primary sample is set aside for Extraction. Here, drugs are separated from hair at a notably lower concentration compared to methods like urine or oral fluid, highlighting the intricacy of hair drug screening.
Positive screening findings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples deemed positive are cleansed as appropriate. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:

Note: While often called "hair follicle tests," the analysis is performed on the hair strand itself, not the follicle beneath 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.
