Gamma-hydroxybutyric acid (GHB) is a naturally occurring analog of gamma-aminobutyric acid (GABA) that has been used in research and clinical medicine for many years. GHB was used clinically as an anesthetic in the 1960s but was withdrawn due to side effects that included seizures and coma. GHB has been implicated in a number of crime types; most notably in drug-facilitated sexual assault. GHB is abused by three main groups of users: Body builders who use the substance believing that it stimulated the release of growth hormone; sexual predators who covertly administer the drug for its sedative and amnesic effects and club-goers (rave parties) who take the drug for its euphoric effects. The short-lived hypnotic effects, relative safety and widespread availability of the drug have made it particularly well suited to this role. The drug has an addictive potential if used for long term. The primary effects of GHB use are those of a CNS depressant and therefore range from relaxation, to euphoria, confusion, amnesia, hallucinations, and coma. Despite the increased regulation, GHB remains widely available through the Internet where one can easily purchase the necessary reagents as well as recipes for home production. There are reports of patients being unresponsive to painful stimuli and cases of oral self-mutilations linked to the abuse of GHB, though quiet rare. Such cases should remind odontologists that intra-oral lesions may be the result of self-mutilation either due to mental illness or altered states caused by the use of prescription or non-prescription drugs.

Background: Naphthalene is an aromatic hydrocarbon that potentially produces methemoglobinaemia but rarely causes hemolysis, especially in children with underlying glucose-6-phosphate dehydrogenase deficiency. Although ingestion of a single moth ball by an older child may not be life threatening, it can be fatal if ingested by a toddler.
Case Presentation: A 2-year-old Singhalese boy developed acute severe hemolysis and methemoglobinaemia following ingestion of a mothball.

Exhaled breath offers an interesting matrix of low invasive sampling of potentially relevant information about the organism's metabolism in the form of volatile organic compounds (VOC). The VOC can be exhaled by the ructus (Islam et al., 2023) or passed the blood-lung barrier for expiration through the lungs.

Introduction: Novel Psychoactive Substance (NPS) use is increasingly prevalent and is often associated with severe acute recreational drug toxicity (ARDT). 258 UK deaths were attributed to NPS use in 2021. Confirmatory testing which identifies NPS is limited by expense and timeliness.

The problem of finding a suitable biomarker to widen the detection window of γ-hydroxybutyric acid (GHB) intake remains a challenge in forensic toxicology. Based on previously published results, the present study deals with the evaluation of a fatty acid ester of GHB (4-palmitoyloxy butyrate (GHB-Pal)) in whole blood as a potential biomarker to extend the detection window of GHB use e.g.
