Recently, hair follicle drug tests have become a more common method for drug screening. Various employers, judicial systems, and substance abuse professionals now prefer them over traditional urine tests. Designed for zero-tolerance drug policies, these tests are implemented by employers, courts, and for individuals on probation. Hair tests predominantly benefit from an extended detection window for up to 90 days, ensuring a reliable and cheat-resistant observable collection, although urine tests are preferred for recent drug use in the last 5 days.

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. Collected closely to the scalp, hair can reveal a detection period of up to roughly three months for alcohol and other substances. Hair is straightforward to collect, challenging to tamper with, and simple to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation tests. For EtG analyses, add-ons, or tests exceeding 10 panels, 150mg of the specimen is suggested. It is advisable to use a jeweler’s scale to weigh the specimen. If scalp hair is absent, a similar quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial hair, axillary hair, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary entry of a sample into a laboratory system. This step includes ensuring the sample was sealed and transported correctly, allotting a random LAN (Laboratory Accessioning Number), and completing any additional data entry not furnished by an electronic chain of custody system.
Screening comprises an initial rapid assessment for substances of abuse. While screening is an economical approach to exclude drug use in most samples, a positive screen must be validated to be valid in a legal setting. Samples that are initially positive in screening necessitate a subsequent confirmation.
If a sample is initially positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at much lower concentrations compared to other methods (for instance, urine or oral fluid), which is why hair drug screening is considered the most complex methodology.
Confirmation of any positive screening outcome is accomplished through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positivity undergo washing prior to confirmation if needed. The entire laboratory process from Accessioning to Confirmation is scrutinized 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. 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.
