Recently, the preference for conducting drug tests has increasingly shifted to hair follicle analysis. Numerous employers, judicial systems, and substance abuse experts are opting for this method over standard urine tests. Organizations with strict anti-drug policies, courts, and those on probation often use hair follicle tests. The main advantage lies in its extended detection window, which reaches up to 90 days and involves a witnessing collection process that's virtually foolproof. Despite this, for detecting drug use within the past five days, urine tests remain the benchmark for accuracy.

The emergence of hair testing has positioned it as an effective method for identifying drug and alcohol consumption. Hair acts as a chronological record of alcohol and other drug usage by encapsulating biomarkers within the strands of hair that are growing. When gathered near the scalp, hair offers up to a three-month window of detection for alcohol and other substances. It's easy to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch hair sample, approximately 200 strands, similar in size to a #2 pencil, situated closest to the scalp equals 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG testing, add-ons, or screenings exceeding 10 panels, it's suggested to use 150mg of the sample. Using a jeweler’s scale for precision weighing is advocated. If scalp hair can't be obtained, an equivalent portion of body hair can be taken. The term head hair specifically implies scalp hair, while body hair encompasses any other types of hair (like facial or axillary).
Process Overview
The procedure for processing drug test results in a lab comprises four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the first phase, where a sample enters a lab's system. This phase entails confirming the sample’s proper sealing and shipment, the allocation of a random LAN (Laboratory Accessioning Number), and the completion of any missing data not supplied by an e-chain of custody system.
The Screening phase conducts an initial preliminary check for the presence of drugs. Although Screening offers a cost-friendly approach to eliminate drug use in most samples, a positive outcome requires further confirmation for courtroom admissibility. Samples that test presumptively positive during Screening must undergo secondary confirmation.
When a sample is found potentially positive in Screening, additional hair is extracted from the original specimen to prepare for the Extraction phase. In this step, drugs are distilled from hair at a much lower concentration level than in other testing approaches (like urine or oral fluids), making hair drug screening the most complex methodology to execute.
To confirm a positive screening outcome, methods like GC/MS, GC/MS/MS or LC/MS/MS are employed. Any presumptive positive samples undergo washing before the confirmation step if necessary. The entire lab process from Accessioning through Confirmation is carefully scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

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.
