Hair analysis has emerged as an effective method for identifying drug and alcohol usage. Hair captures a comprehensive timeline of substance use by embedding biomarkers within the fibers of the growing hair. When taken close to the scalp, it offers a detection period of up to around 90 days for drugs and alcohol. Hair is easy to gather, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches, consisting of roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional tests, or panels exceeding 10, a quantity of 150mg is advised. It is suggested to measure the specimen with a jeweler’s scale. If scalp hair is not available, an equivalent portion of body hair may be used. References to head hair pertain exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The key steps in the lab handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the sample’s introductory processing into a laboratory system. This step involves confirming that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody.
Screening is a preliminary evaluation for signs of drug abuse. Although Screening is an economical method to eliminate drug usage for most samples, any positive results require confirmation to be legally valid. Samples that are tentatively positive during Screening need a confirming test.
For presumptively positive samples in the Screening phase, more hair is extracted from the initial specimen and prepared for Extraction. In this step, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underscoring why hair drug screening is the most complex to execute.
Verification of any positive Screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if required. The entire laboratory process, from Accessioning to Verification, is evaluated under the CAP (College of American Pathologists) Hair designation in addition to ISO / IEC 17025 accreditation.

Limitations:
Note: Although occasionally termed "hair follicle tests", the evaluation actually examines the hair strand and not 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.
