BACKGROUND Chronic methamphetamine abuse can lead to multiple health hazards. In particular, the substance is associated with devastating effects on oral health including symptoms such as rampant caries, gingiva inflammation, and xerostomia, whereby the term "Meth Mouth" occurs in the current literature. However, "Meth Mouth" pathology is primarily described on the basis of individual cases or ...
INTRODUCTION Methamphetamine is a powerful psychostimulant that causes significant neurological impairments with long-lasting effects and has provoked serious international concerns about public health. Denial of drug abuse and drug craving are two important factors that make the diagnosis and treatment extremely challenging. Here, we present a novel and rapid noninvasive method with potential ...
Sigma (σ) receptors have recently been identified as potential targets for the development of novel therapeutics aimed at mitigating the effects of methamphetamine. Particularly, σ receptors are believed to mitigate some of the neurotoxic effects of methamphetamine through modulation of dopamine, dopamine transporters and body temperature. Furthermore, recent evidence suggests that targeting σ ...
This study was conducted to better understand the distribution characteristics of methamphetamine and amphetamine in urine and hair specimens collected from alleged methamphetamine users in the local population. It is anticipated that the data hereby obtained will be helpful to the interpretation of the time and pattern of drug use. Eight alleged methamphetamine-using arrestees from Keelung Pol...

BACKGROUND Substance use has been associated with high-risk sexual behavior among men who have sex with men (MSM) both in the U.S. and around the world. Recent efforts by local organizations in San Francisco have specifically targeted methamphetamine use in this population. METHODS We tracked methamphetamine and other substance use among men who have sex with men (MSM) in San Francisco from 2...
We compare antemortem whole-blood to postmortem peripheral blood concentrations of methamphetamine and its metabolite amphetamine in three medical examiner cases. Antemortem specimens, initially screened positive for methamphetamine by ELISA, were subsequently confirmed, together with the postmortem specimens, by GC-MS analysis following solid-phase extraction. Methamphetamine peripheral blood ...
Methamphetamine use has increasingly become linked with sexual risk behaviors among men have sex with men (MSM). Yet, the majority of research has been done with methamphetamine dependent MSM or with samples in which addiction to the substance was not evaluated. Furthermore, research with methamphetamine-using MSM in the Southern U.S. is lacking. In this study, focus groups and in-depth intervi...
1. (14)C-labelled amphetamine and methamphetamine were injected into rats cannulated at the bile duct under thiopentone anaesthesia and the output of their metabolites in urine and bile was determined. 2. With amphetamine, 69% of the (14)C was excreted in the urine and 16% in the bile in 24h. The main metabolite in bile was the glucuronide of 4-hydroxyamphetamine. The output of unchanged amphet...
Little research exists on effective strategies to prevent methamphetamine production, distribution, sales, use, and harm. As a result, prevention practitioners (especially at the local level) have little guidance in selecting potentially effective strategies. This article presents a general causal model of methamphetamine use and harms that reflects the available findings from either research s...
