Methamphetamine dependence has grown into an epidemic in the United States. An estimated 10.4 million people aged 12 years or older have tried methamphetamine.1 While the prevalence of methamphetamine use has remained constant in recent years, severity of use is increasing. The number of methamphetamine users in the past month meeting criteria for amphetamine abuse or dependence during the past...

a b s t r a c tintroduction: craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. in this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. methods: first a series of visual cues which could induce craving was identified by 5 discussion sessions b...

OBJECTIVE The objective of this study was to determine the risk of lifetime and current methamphetamine-induced psychosis in patients with methamphetamine dependence. The association between psychiatric co-morbidity and methamphetamine-induced psychosis was also studied. METHODS This was a cross-sectional study conducted concurrently at a teaching hospital and a drug rehabilitation center in ...

Methamphetamine (MA) is a potent psychostimulant drug whose abuse has become a global epidemic in recent years. Firstly, this review article briefly discusses the epidemiology and clinical pharmacology of methamphetamine dependence. Secondly, the article reviews relevant animal literature modeling methamphetamine dependence and discusses possible mechanisms of methamphetamine-induced neurotoxic...

Glutathione S-transferases (GSTs; EC: 2.5.1.18) are ubiquitous multifunctional enzymes, which play a key role in cellular detoxification. Functional genetic polymorphisms in genes encoding GSTM1 (a member of GST class mu; OMIM: 138350), and GSTT1 (a member of GST class theta; OMIM: 600436) have been well defined. The functional null alleles of GSTM1 and GSTT1 represent deletions of GSTM1 and GS...

We investigated the differential influence of family dysfunction on alcohol and methamphetamine dependence in Japan using the Addiction Severity Index (ASI), a useful instrument that multilaterally measures the severity of substance dependence. The participants in this study were 321 male patients with alcohol dependence and 68 male patients with methamphetamine dependence. We conducted semi-st...

AIM To investigate the safety and efficacy of once-daily supervised oral administration of sustained-release dexamphetamine in people dependent on methamphetamine. DESIGN Randomized, double-blind, placebo-controlled trial. PARTICIPANTS Forty-nine methamphetamine-dependent drug users from Drug and Alcohol Services South Australia (DASSA) clinics. INTERVENTION Participants were assigned ran...

The ability of drugs of abuse to cause dependence can be viewed as a form of neural plasticity. Recently, we have demonstrated that tumor necrosis factor-α (TNF-α) increases dopamine uptake and inhibits methamphetamine-induced dependence. Moreover, we have identified a novel molecule 'shati' in the nucleus accumbens of mice treated with methamphetamine using the PCR-select cDNA subtraction meth...

OBJECTIVE The authors examined the separate and combined effects of methamphetamine dependence and HIV infection on brain morphology. METHOD Morphometric measures obtained from magnetic resonance imaging of methamphetamine-dependent and/or HIV-positive participants and their appropriate age- and education-matched comparison groups were analyzed. Main effects of age, HIV infection, methampheta...
