Recently, there's been an increasing shift towards hair follicle drug testing as the go-to method. Employers, courts, and Substance Abuse professionals often prefer hair tests over traditional urine analyses. Hair follicle tests are favored by employers enforcing no-drug policies, by courts, and for individuals on probation, due to their extended drug use detection capabilities of up to 90 days and almost unbeatable accuracy. However, for identifying drug use within the past 5 days, urine tests remain more precise.

Hair examinations are increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within the strands of growing hair. When sourced near the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and convenient to transport.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal sample size for both screening and verification. For tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advisable. Using a jeweler's scale is suggested for weighing the sample. If scalp hair isn't present, an equivalent weight of body hair can be gathered. References to head hair specifically denote scalp hair. Body hair encompasses all other types, such as facial and axillary.
Process Overview
The four crucial stages in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary input of a sample into a lab system. This step includes confirming the sample’s proper sealing and shipping, assigning a random LAB (Laboratory Accessioning Number), and completing any remaining data entry absent from an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient approach to dismiss drug usage for most samples, any positive findings necessitate confirmation to be valid in legal settings. Samples showing presumptive positive results in Screening require a follow-up confirmation.
When a sample shows a presumptive positive during Screening, more hair is extracted from the initial sample and prepared for Extraction. At this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening poses the greatest challenge in methodology.
Confirmation of any positive Screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with tentative positive results are cleansed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 criteria.

Limitations:
Note: Despite commonly being termed as "hair follicle tests", the analysis pertains to the hair strand itself, not the subscalp follicle

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.
