Recently, hair follicle drug testing has increasingly become a standard method for substance testing. Employers, courts, and Substance Abuse experts are opting for hair drug tests over traditional urine ones. Hair tests are popular among employers with zero drug tolerance, courts, and probation programs because they detect drug use over up to 90 days, are hard to evade, and use observed collections. However, urine tests remain the most accurate for detecting substances used within the last five days.

Hair testing is increasingly regarded as a potent method for detecting drug and alcohol usage. It offers a prolonged record of substances by capturing biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, the hair can reveal a detection window up to roughly 3 months for alcohol and drug usage. Hair is easy to gather, relatively tough to tamper with, and straightforward to dispatch.
A 1.5-inch segment containing approximately 200 strands of hair (similar in size to a #2 pencil) nearest to the scalp yields 100mg, ideal for screening and confirmation. For EtG, additional panels, and/or tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't an option, an equivalent amount of body hair can be collected. Note that head hair pertains solely to scalp hair, whereas body hair covers all other types (face, axillary, etc.).
Process Overview
The laboratory processing of hair drug testing involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the first step, where a sample is processed into the lab’s system, confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry in the absence of an electronic chain of custody system.
Screening provides an initial fast assessment for substances of abuse. While it's cost-efficient to eliminate drug usage in most samples, a positive screen necessitates confirmation to be legally valid. Samples that are presumptively positive in Screening require secondary confirmation.
In the event of a presumptive positive during Screening, more hair is extracted from the original sample and prepped for Extraction. Here, drugs are extracted from hair at a notably lower concentration compared to other testing methods (e.g., urine or oral fluid), which is why hair drug testing is one of the most challenging methodologies to execute.
Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive are washed as part of the preparation for confirmation as needed. The complete laboratory processing from Accessioning through Confirmation is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

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.
