Methamphetamine abuse is on the rise, particularly by women of childbearing age. This article describes the history and effects of methamphetamine use. The authors examine the ways exposure to the manufacture of this drug affects clients and social workers in the course of their work. Because children are frequently found at the scene of a manufacturing laboratory, the child welfare system ofte...

Drug abuse is a public health and social problem. A number of studies have reported that drug addiction is associated with microRNAs (miRNAs). By comparing the expression of miRNAs in the serum exosomes of methamphetamine-dependent and ketamine-dependent rats, the aim of the present study was to provide insights into the miRNA-mediated associations between the two groups. Published results on c...

Abuse of the powerfully addictive psychostimulant, methamphetamine, occurs worldwide. Recent studies have suggested that methamphetamine-induced dopaminergic neurotoxicity is related to oxidative stress. In response to nerve activation, the mitochondrial respiratory chain is rapidly activated. The enhancement of mitochondrial respiratory chain activation may induce oxidative stress in the brain...

Chronic methamphetamine abuse commonly leads to psychosis, with positive and cognitive symptoms that are similar to those of schizophrenia. Methamphetamine induced psychosis (MAP) can persist and diagnoses of MAP often change to a diagnosis of schizophrenia over time. Studies in schizophrenia have found much evidence of cortical GABAergic dysfunction. Methamphetamine psychosis is a well studied...

The blood brain barrier (BBB) is a highly dynamic interface between the central nervous system (CNS) and periphery. The BBB is comprised of a number of components and is part of the larger neuro(glio)vascular unit. Current literature suggests that psychostimulant drugs of abuse alter the function of the BBB which likely contributes to the neurotoxicities associated with these drugs. In both pre...

This project evaluated two behavioral therapies for substance abuse and concomitant sexual risk behaviors applied to primarily stimulant-abusing gay and bisexual men in Los Angeles. One hundred twenty-eight participants were randomly assigned to 16 weeks of a gay-specific cognitive-behavioral therapy (GCBT, n = 64) or to a gay-specific social support therapy (GSST; n = 64), with follow-up evalu...

Both lobeline and lobelane attenuate methamphetamine self-administration in rats by decreasing methamphetamine-induced dopamine release via interaction with the vesicular monoamine transporter-2 (VMAT2). A novel derivative of nor-lobelane, cis-2,5-di-(2phenethyl)-pyrrolidine hydrochloride (UKCP-110) and its trans-isomers, (2R,5R)-trans-di-(2phenethyl)-pyrrolidine hydrochloride (UKCP-111) and (2...

recent studies on rodents showed successful treatment outcomes for cocaine dependence by using buprenorphine and naltrexone without the risk of dependence on them. such findings could provide a new hope on treatment of cocaine, methamphetamine or other stimulants dependence. the idea of using these medicines was formed once dr. nora volkow (director of nation institute for drug abuse) based on ...

BACKGROUND Methamphetamine is a psychomotor stimulant with abuse liability and a substrate for catecholamine uptake transporters. Acute methamphetamine elevates extracellular dopamine, which in the midbrain can activate D2 autoreceptors to increase a G-protein gated inwardly rectifying potassium (GIRK) conductance that inhibits dopamine neuron firing. These studies examined the neurophysiologic...

Estimation of illicit drug use on a community level by wastewater-based epidemiology (WBE) is both an objective and reliable way to establish near real-time results. Wastewater samples were collected at eleven timepoints in Reykjavik from 2017 2020. The commonly abused drugs Iceland (amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA), cocaine, cannabis) was estimated. Solid ...
