Hair follicle drug tests have become more prevalent in recent times for drug screening. Many employers, court systems, and Substance Abuse experts now prefer this approach over a typical urine test. These tests are utilized by employers enforcing strict drug-free policies, courts, and probation clients. The key advantage is the extended detection window, often up to 90 days, conducted under supervised conditions to minimize the possibility of cheating. For detecting recent drug use within the last 5 days, urine tests remain the best choice.

Assessing drug and alcohol usage through hair testing has emerged as a formidable method. Hair captures long-term data on these substances by embedding biomarkers within the hair shaft as it grows. When taken from near the scalp, hair offers up to an approximately 90-day detection period for substances. Hair is straightforward to gather, challenging to tamper with, and hassle-free to transport.
A 1.5-inch collection of approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp provides 100mg, which is the optimum amount for testing and verification. For tests like EtG, and additions beyond 10 panels, 150mg is preferable. Measuring the sample with a jeweler’s scale is advisable. If head hair is inaccessible, body hair in an equivalent volume can be utilized. "Head hair" implies only scalp hair, while "body hair" encompasses all other types (like facial, axillary, etc.).
Process Review
The crucial steps entailed in laboratory examination for drug test outcomes include Accessioning, Screening, Extraction, and Verification.
Accessioning denotes the preliminary handling of a sample into the lab’s inventory. It involves ensuring the sample was properly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number) randomly, and finalizing any residual data entry absent from an electronic custody chain.
Screening consists of an initial prompt inspection for banned substances. Although it's an economical way to exclude drug usage for most samples, a positive result necessitates confirmation for court submission. Any sample indicating a presumptive positive during Screening needs a subsequent confirmation.
For samples showing presumptive positives in Screening, more hair is sourced from the original collection for the Extraction phase. In this step, drugs are extracted at a decidedly lower concentration than through other methods (e.g., urine or saliva), making hair drug screening the most intricate technique.
Verification of a positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo washing before confirmation if required. The complete lab procedure from Accessioning to Verification adheres to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.

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.
