Pragst F, Niebel A, Thurmann D, Dullin M, Eichberg S, Mörlein F, Hartwig S. Is there a relationship between abuse of alcohol and illicit drugs seen in hair results? Drug Test Anal 2024. [PMID: 38686500 DOI: 10.1002/dta.3702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/09/2024] [Accepted: 04/10/2024] [Indexed: 05/02/2024]
Abstract
Combined use of alcohol and illicit drugs is a serious health and social problem. In this study, it was examined, whether a relationship between alcohol and drug abuse can be ascertained by comparison of alcohol marker and drug concentrations in hair. In the frame of a social support system for families with parental abuse of illicit drugs, hair samples were analyzed between 2011 and 2022 for methadone, heroin (6-acetylmorphine), cocaine, amphetamine, ecstasy (MDMA), cannabinoids (THC), and the alcohol markers ethyl glucuronide (EtG) and ethyl palmitate (EtPa). For 1314 hair samples from adolescent and adult family members, the hair results show a prevalence of combined occasional or regular drug use and social or abusive alcohol use of 41%-60% except heroin (35%). The drug concentrations were statistically compared in the three categories of abstinence or moderate drinking, social drinking, and alcohol abuse. For the most frequently detected drug cocaine (n = 703), a significant increase of the concentrations with rising alcohol consumption was found. The frequent detection of cocaethylene proved the preferred simultaneous intake of both substances. For THC (n = 489), no significant difference between the alcohol consumer groups was seen. Concerning the less frequently detected methadone (n = 89), 6-acetylmorphine (n = 92), amphetamine (n = 123), and MDMA (n = 105), no clear trend between drug and alcohol marker results was determined. It is concluded that the evaluation of hair results is an appropriate way to study the extent of combined drug-alcohol consumption and complements other studies based on acquisition of consumption data by interview or questionnaire.

Neurotoxicology 2023; 95:136-143. [PMID: 36736785 DOI: 10.1016/j.neuro.2023.01.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023]
Abstract
Combined diazepam-ethanol poisoning is common in forensic toxicology. Both diazepam and ethanol can inhibit the central nervous system via the γ-aminobutyric acid (GABA) ligand gated chloride ion channel, GABAA Receptor (GABAAR). As the common target of diazepam and ethanol, whether GABAAR is the key target of their combined action remains unclear. This study aimed to explore their interaction based on the synergistic mechanisms between diazepam and ethanol targeting the GABAAR. Four models were built in silico based on the crystal structure of GABAAR. Molecular dynamic processes of the four models were simulated by the GPU-accelerated pmemd.cuda program in the Amber18 package. Results showed that ethanol inclined to combine the adjacent GABA or diazepam sites, minimized fluctuations of the root-mean-square deviation (RMSD) in the molecular dynamic process of GABA or diazepam binding the GABAAR, and increased the release of binding energy of GABA or diazepam binding the GABAAR. Results also showed that diazepam had less effect on the RMSD fluctuation or the binding energy release of GABA binding GABAAR. The formation of complex of diazepam and GABAAR could minimize the RMSD fluctuation and increase binding energy release of ethanol binding GABAAR. Thus, ethanol, bridging GABA and diazepam, could strengthen the complex of GABA binding the GABAAR, as well as the complex of diazepam binding the GABAAR. However, whether diazepam binds GABAAR or not, it cannot affect GABA binding the GABAAR; and yet the complex of diazepam and GABAAR can stabilize the complex of ethanol and GABAAR.

Abstract
The recreational use of a drug such as 3,4-methylenedioxymethamphetamine (MDMA), also known as "ecstasy," may be associated with significant side effects. Although liver failure with ecstasy is rare, the use of the drug should be investigated in all patients with severe hepatitis of unknown origin. Early diagnosis and intervention can prevent patients from ending up in liver transplantation. Here, we present a case of a 27-year-old female who developed acute liver injury secondary to recreational intoxication with ecstasy.

[PMID: 34554408 PMCID: PMC8639540 DOI: 10.1007/s12640-021-00416-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 09/07/2021] [Accepted: 09/11/2021] [Indexed: 11/10/2022]
Abstract
Although MDMA (ecstasy) is a relatively safe recreational drug and is currently considered for therapeutic use for the treatment of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), recreational MDMA use occasionally elicits hyperthermia and hyponatremia, sometimes with a fatal outcome. Specific risk factors for both adverse effects are profuse sweating while vigorously dancing under unfavorable conditions such as high ambient temperatures and insufficient fluid suppletion which result in dehydration. Concomitant use of MDMA and alcohol is highly prevalent, but adds to the existing risk, because alcohol facilitates the emergence of MDMA-induced adverse events, like hyperthermia, dehydration, and hyponatremia. Because of potential health-related consequences of concomitant use of MDMA and alcohol, it is important to identify the mechanisms of the interactions between alcohol and MDMA. This review summarizes the main drivers of MDMA-induced hyperthermia, dehydration, and hyponatremia and the role of concomitant alcohol use. It is shown that alcohol use has a profound negative impact by its interaction with most of these drivers, including poikilothermia, exposure to high ambient temperatures, heavy exercise (vigorous dancing), vasoconstriction, dehydration, and delayed initiation of sweating and diuresis. It is concluded that recreational and clinical MDMA-users should refrain from concomitant drinking of alcoholic beverages to reduce the risk for adverse health incidents when using MDMA.

Abstract
Preclinical and clinical studies indicate that 3,4-methylenedioxymethamphetamine (MDMA; 'ecstasy'), in addition to having abuse potential, may elicit acute and persistent abnormalities of varying severity at the central level. Importantly, neurotoxic effects of MDMA have been demonstrated in experimental animals. Accordingly, central toxicity induced by MDMA may pose a serious harm for health, since MDMA is among the substances that are used for recreational purposes by young and adult people. This review provides a concise overview of recent findings from preclinical and clinical studies that evaluated the central effects of MDMA, and the mechanisms involved in the neurotoxicity induced by this amphetamine-related drug.
