While the usage of illicit drugs in itself carries significant health risks and associated toxicities, drugs that are adulterated to give them volume, alter their psychogenic properties, and make them cheaper to produce are to be considered even more dangerous. Cocaine is one of them, and it is now most commonly being adulterated with levamisole. We report a case of a 37-year-old female with the chief complaint of painful skin lesions and wounds on both of her upper and lower extremities for three weeks duration...

Although planarians are established model organisms in developmental biology and regeneration studies, in the last forty years or so, they have caught the attention of pharmacologists, especially to study the pharmacology of drugs of abuse. This review covers the following topics: some fundamentals of the history of animal models and planarians in biomedical research; an abbreviated story of systematic pharmacology research using planarians as a model organism; an example of how planarians are contributing to the search for compounds against acute cocaine toxicity; an analysis of the number of papers on planarians and pharmacological topics from 1900-2016; some perspectives on pharmacology in developmental and regeneration studies, arguing in favor of the planarian model as a leading subject for this interdisciplinary area of research, and finally some concluding thoughts...

It is a grand challenge to develop a truly effective medication for treatment of cocaine overdose. The current available, practical emergence treatment for cocaine overdose includes administration of a benzodiazepine anticonvulsant agent (e.g. diazepam) and/or physical cooling with an aim to relieve the symptoms. The inherent difficulties of antagonizing physiological effects of drugs in the central nervous system have led to exploring protein-based pharmacokinetic approaches using biologics like vaccines, monoclonal antibodies, and enzymes...

Local anesthetics are commonly used medicines in clinical settings. They are used for pain management during minor interventional treatments, and for postoperative care after major surgeries. Cocaine is the well-known origin of local anesthetics, and the drug and related derivatives have long history of clinical usage for more than several centuries. Although illegal use of cocaine and its abuse are social problem in some countries, other local anesthetics are safely and effectively used in clinics and hospitals all over the world...

BACKGROUND: Cocaine use disorder (CUD) is a complex health condition, especially when it is accompanied by comorbid psychiatric disorders (dual diagnosis). Dual diagnosis is associated with difficulties in the stratification and treatment of patients. One of the major challenges in clinical practice of addiction psychiatry is the lack of objective biological markers that indicate the degree of consumption, severity of addiction, level of toxicity and response to treatment in patients with CUD...

Illicit drugs have been identified as emerging aquatic pollutants because of their widespread presence in freshwaters and potential toxicity towards aquatic organisms. Among illicit drug residues, cocaine (COC) and its main metabolites, namely benzoylecgonine (BE) and ecgonine methyl ester (EME), are commonly detected in freshwaters worldwide at concentration that can induce diverse adverse effects to non-target organisms. However, the information of toxicity and mechanisms of action (MoA) of these drugs, mainly of COC metabolites, to aquatic species is still fragmentary and inadequate...

Neuropsychiatric disorders caused by toxic substances pose a great diagnostic challenge due to the large variety of changes caused in the central and peripheral nervous system. The pathogenetic mechanisms at work are multifaceted and partly not solved. In human drug abusers (cannabis, opiates, cocaine, amphetamines, methamphetamine and "designer drugs"), a broad spectrum of central nervous system alterations are observed including infarction, intracerebral and subarachnoidal hemorrhage, hypoxic-ischemic leukoencephalopathy, infections, neuronal loss, specific astroglial and microglial reaction patterns, and vascular changes, including the endothelial cell as well as the basal lamina...

A great diversification of drugs of abuse has been observed in recent years, both in the populations using them and in the types of drugs. Although dependency and psychiatric disorders associated with the abuse of these substances is well known, somatic complications, uro-nephrotoxicity in particular, are less recognized. We propose here an overview of the products used by drugs abusers in France, through the analysis of the national pharmaco-epidemiological study Observation des produits psychotropes illicites ou détournés de leur utilisation médicamenteuse (OPPIDUM)...

In 1924, the Therapeutic Research Committee of the American Medical Association appointed a special committee to investigate deaths following the administration of local anesthetics. The Committee for the Study of Toxic Effects of Local Anesthetics found procaine, although a safer clinical alternative to cocaine, was capable of causing death when large doses were injected into tissues and advised that it should be used with caution. This article describes a collaboration beginning in 1928 between Dr John Lundy of the Mayo Clinic and Dr Robert Isenberger of the University of Kansas, which arose from a controversy surrounding systemic adverse reactions to procaine...

Butyrylcholinesterase (BChE) is an enzyme with broad substrate and ligand specificities and may function as a generalized bioscavenger by binding and/or hydrolyzing various xenobiotic agents and toxicants, many of which target the central and peripheral nervous systems. Variants of BChE were rationally designed to increase the enzyme's ability to hydrolyze the psychoactive enantiomer of cocaine. These variants were cloned, and then expressed using the magnICON transient expression system in plants and their enzymatic properties were investigated...

BACKGROUND: Use of new psychoactive substances (NPS) has increased over the last decade. During this period, variability of both clinical presentations and chemical compositions of these compounds has increased. Synthetic cannabinoids (SCs) are the most commonly used NPS and there are more than 100 documented unique molecules in this class. "Black Mamba", often associated to ADB-FUBINACA, is the most commonly used SC in Colorado. It has been linked to kidney injury, myocardial toxicity, seizures, and death...

Our study aimed to evaluate crack cocaine effects in different life stages of the marine mussel Perna perna. For this purpose, fertilization rate, embryo-larval development, lysosomal membrane stability and DNA strand breaks were assessed. Effect concentrations in gametes and in larval development were found after 1h (IC50=23.53mg·L(-1)) and 48h (IC50=16.31mg·L(-1)), respectively. The highest tested concentration showing no acute toxicity (NOEC) was 10mg·L(-1), while the lowest observed effect concentration (LOEC) was 20mg·L(-1)...

Cocaine use is increasing around the world and its purity is frequently altered through dilution, substitution, contamination, and adulteration. Sugars, talc, starch, and carbonates represent the principal diluents of cocaine, while phenacetin, levamisole, caffeine, and lidocaine are its major adulterants in Europe. Levamisole is used because it is an odorless powder, with physical properties similar to cocaine, and it has reasonable cost and availability, being widely used in veterinary medicine. For this study, we analyzed 88 cocaine samples...

Cadmium (Cd) is a naturally occurring trace metal that is widely considered to be highly toxic to aquatic organisms and a significant health hazard to humans (Amzal et al., 2009; Bernhoft 2013; Burger, 2008; Satarug et al., 2009). The zebrafish (Danio rerio) has been used as a model organism for toxicological studies with Cd (Banni et al., 2011; Blechinger et al., 2007; Chow et al., 2009; Chow et al., 2008; Favorito et al., 2011; Kusch et al., 2007; Matz et al., 2007; Wang and Gallagher, 2013). We asked what the lasting longitudinal effects would be from short early developmental Cd exposure (between 24 and 96h post-fertilization) in a range that larvae might experience living atop typical Cd-containing surface sediments (0, 0...

Myocardial infarction commonly occurs due to rupture of atherosclerotic plaque in the coronary arteries and is manifested on coronary angiography. Myocardial infarction with angiographically normal coronary arteries can occur due to hypercoagulable state, coronary spasm, embolism, arteritis, congenital condition and drugs. Illicit drugs such as cocaine, amphetamines and marijuana are known to cause myocardial infarction. Of the many medications that are associated with cardiovascular toxicity, chemotherapeutic agents form a large group with both acute and delayed cardiotoxicity...

BACKGROUND: Powdery drugs such as cocaine and heroin are frequently adulterated or diluted predominantly to obtain more doses and to increase the drug dealer's profits, but also to enhance, to modify or to oppose drug effects. The aim of this report is to provide an overview of the recent scientific literature on medicines as well as on new psychoactive substances, used as cutting agents (i.e. pharmacologically active adulterants) and on the related adverse health effects on consumers, possibly due to the synergistic effect of the adulterants laced with substances of abuse...

Toxic leukoencephalopathy represents a process of structural alteration of the white matter. It is caused by substance abuse including drugs such as heroin, cocaine, toluene and ethanol. We reported the clinical, radiological and autopsy findings of a rare case of toxic leukoencephalopathy following chronic methamphetamine (MA) usage. A 34-year-old man with a 3-year history of MA abuse experienced progressive sluggish state, limb weakness, inability to stand and eating disorders, followed by rapid progression to coma and death...

Bath salts, or synthetic cathinones, have cocaine-like or amphetamine-like properties and induce psychoactive effects via their capacity to modulate serotonin (5-HT) and dopamine (DA). Structurally distinct synthetic cathinones are continuously being generated to skirt existing drug laws. One example of these modified compounds is cathinone phthalimide (CP), which has already appeared on the global market. The lack of toxicological studies on the effects of CP on monoaminergic systems led to the development of the present study in order to generate an acute toxicity profile for CP, and to clarify whether it primarily affects both dopamine and serotonin, like the synthetic cathinones mephedrone and methylone, or primarily affects dopamine, like 3, 4-methylenedioxypyrovalerone (MDPV)...

INTRODUCTION: Foetal abuse is that intentional or negligent act that causes a harmful effect to the foetus. It is a type of abuse difficult to diagnose and handle. Some indicators of suspicion are the absence of gestational control, the maternal consumption of toxic substances, or the problematic maternal social environment. OBJECTIVE: To analyse the cases of foetal abuse registered in Catalonia between 2011 and 2014 to identify the risk profile. METHODS: A cross-sectional descriptive study was conducted on a sample of 222 cases of prenatal abuse registered in Catalonia between 2011 and 2014...
