However, objective interpretation of hair drug concentrations remains challenging due to significant inter\u2010study variability, even for identical compounds. This study included hair analysis results upon the prosecutor's request over six years in the Grenoble Forensic Laboratory in France. Hair analysis was performed using liquid chromatography coupled with tandem mass spectrometry (LC\u2013MS\/MS) on Sciex\u00ae 5500QT and Waters\u00ae TQ\u2010XS mass spectrometers, following the French Society of Analytical Toxicology (SFTA) guidelines. Hair proficiency quality testing ensured reproductive results. This compendium describes 38 cases with hair analysis, including child's exposure and chemical abuse involving both children and the elderly. The study population predominantly involved female victims (84.2%), aged 5\u2009months to 90\u2009years. At least one substance was detected in hair in 26 cases. In twelve cases, hair analyses supplemented blood or urine testing. Substances identified were cocaine, THC, and levamisole in child exposure cases; alprazolam, diazepam, loprazolam, and tiapride in chemical abuse; and mainly MDMA, cocaine, paroxetine, and THC in other cases. This compendium contributes valuable data to the literature, enhancing the interpretation of hair drug concentrations across a broad spectrum of cases characterized by diverse age ranges, hair characteristics, timeframes, and circumstances. This work provides critical comparative data for interpreting findings in forensic cases.<\/jats:p>","DOI":"10.1111\/1556-4029.70330","type":"journal-article","created":{"date-parts":[[2026,4,17]],"date-time":"2026-04-17T04:09:15Z","timestamp":1776398955000},"page":"1767-1782","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Insights from a six\u2010year hair drug analysis compendium in drug\u2010facilitated crimes involving vulnerable population cases"],"prefix":"10.1111","volume":"71","author":[{"given":"Amandine","family":"Fort","sequence":"first","affiliation":[{"name":"Clinique de M\u00e9decine L\u00e9gale CHU Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Coralie","family":"Boudin","sequence":"additional","affiliation":[{"name":"D\u00e9partement de M\u00e9decine L\u00e9gale Universit\u00e9 Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00e9l\u00e8ne","family":"Eysseric\u2010Guerin","sequence":"additional","affiliation":[{"name":"D\u00e9partement de M\u00e9decine L\u00e9gale Universit\u00e9 Grenoble Alpes  Grenoble France"},{"name":"Laboratoire de Pharmacologie, Pharmacog\u00e9n\u00e9tique et Toxicologie CHU Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginie","family":"Scolan","sequence":"additional","affiliation":[{"name":"Clinique de M\u00e9decine L\u00e9gale CHU Grenoble Alpes  Grenoble France"},{"name":"D\u00e9partement de M\u00e9decine L\u00e9gale Universit\u00e9 Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Paysant","sequence":"additional","affiliation":[{"name":"Clinique de M\u00e9decine L\u00e9gale CHU Grenoble Alpes  Grenoble France"},{"name":"D\u00e9partement de M\u00e9decine L\u00e9gale Universit\u00e9 Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clo\u00e9","family":"Scherpereel","sequence":"additional","affiliation":[{"name":"Clinique de M\u00e9decine L\u00e9gale CHU Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00e9lissa","family":"Revet","sequence":"additional","affiliation":[{"name":"Clinique de M\u00e9decine L\u00e9gale CHU Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7oise","family":"Stanke\u2010Labesque","sequence":"additional","affiliation":[{"name":"Laboratoire de Pharmacologie, Pharmacog\u00e9n\u00e9tique et Toxicologie CHU Grenoble Alpes  Grenoble France"},{"name":"Inserm 1300\u2010 HP2, CHU Grenoble Alpes, University Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Th\u00e9o","family":"Willeman","sequence":"additional","affiliation":[{"name":"Clinique de M\u00e9decine L\u00e9gale CHU Grenoble Alpes  Grenoble France"},{"name":"Laboratoire de Pharmacologie, Pharmacog\u00e9n\u00e9tique et Toxicologie CHU Grenoble Alpes  Grenoble France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,16]]},"reference":[{"key":"e_1_2_10_2_1","volume-title":"Drug\u2010facilitated crimes \u2013 2022 investigations","author":"Chaouachi L","year":"2024"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.legalmed.2023.102297"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11419\u2010025\u201000723\u20106"},{"key":"e_1_2_10_5_1","volume-title":"What are the causes of accidental poisoning in children, and how can they be prevented?
