Over the years, there's been a growing preference for hair follicle drug tests in drug screenings. Courts, employers, and Substance Abuse professionals often opt for hair testing over the conventional urine tests. Zero-tolerance employers and probation systems rely on them because of their longer detection period—up to 90 days—and collection integrity, making manipulation almost impossible. Nonetheless, for recent usage detection within five days, urine tests remain superior.

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a chronological record of exposure to alcohol and drugs by capturing biomarkers in the growing hair fibers. When collected near the scalp, hair can offer an approximate 3-month detection window for both alcohol and drugs. Hair collection is straightforward, tampering is challenging, and shipping is hassle-free.
A 1.5-inch section comprising around 200 hair strands (about the same diameter as a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample size for screening and verification. For EtG, additional tests, and evaluations exceeding 10 panels, a 150mg sample is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a comparable quantity of body hair might be substituted. “Head hair†denotes scalp hair specifically. “Body hair†applies to all other types (facial, axillary, etc.).
Process Overview
The four fundamental stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial steps of integrating a specimen into a laboratory system. This phase ensures the sample was properly sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and completes any extra data entry missing from an electronic chain of custody documentation.
Screening entails a quick preliminary check for substance abuse. Screening offers a cost-effective mechanism to identify drug usage across many samples; however, a positive result requires confirmation to be accepted in a legal setting. Samples suspected of being positive during Screening must undergo secondary confirmation.
If a sample is suspected of being positive during Screening, additional hair is retrieved from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), emphasizing why hair drug screening is notably complex.
Confirmed positive screening outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples undergo necessary washing. The comprehensive lab process from Accessioning to Confirmation is reviewed under both CAP (College of American Pathologists) Hair designation and accredited 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.
