| Popis: | In this study, forensic cases involving the use of Gamma Hydroxy Butyric acid (GHB) from the second half of 1999 through the second half of 2001 in The Netherlands (blood >5 mg/l and urine >10 mg/l) are described. GHB was analysed by GC–MS after lactone formation and using GHB-d6 as internal standard. The results are divided into three groups: cases of chemical submission, cases of driving under the influence and cases of unknown causes of death. GHB was found in six cases of possible chemical submission. In these cases, relatively low concentrations of GHB were found. The results show that in cases of chemical submission, urine should be analyzed, because GHB is present longer in urine than in blood. The police should collect the samples in containers that do not contain citrate as anticoagulant. Especially at low levels of GHB, the formation of GHB in these tubes hampers an interpretation of the results. GHB was found in 13 cases of driving under the influence. In contrast to the cases of chemical submission, high concentrations of GHB were found, corresponding with observations of extreme sleepiness or temporary loss of consciousness. GHB was found in 16 cases of unexplained death: the measured range of GHB concentrations in blood might correspond to effects such as drowsiness, but not to serious toxicity of GHB. In 4 of these 16 cases, the role of GHB could be excluded. In the remaining cases, the role of GHB remains unclear; more research into “background” concentrations of GHB in post-mortem material is required. The incidence of the use of GHB in The Netherlands cannot be derived from these toxicological data. As GHB is not routinely found during systematical toxicological analyses, these data may seriously underestimate the use of GHB. Therefore, information from the police to the forensic institute is essential. |
