Amphetamine use and psychiatric admissions: a 10-year perspective.

Australas Psychiatry 2021 May 19:10398562211014227. Epub 2021 May 19.

Sydney Medical School, Northern Clinical School, University of Sydney, North Ryde, NSW, Australia.

Objective: We aimed to (i) describe the 10-year trend in admissions associated with amphetamine use, (ii) describe the distinguishing characteristics of people with an amphetamine-related diagnosis (ARD) and (iii) examine predictors of repeated admissions among people with an ARD.

Method: We conducted a retrospective cohort study. We (i) counted the number of admissions with an ARD and evaluated any trends, and using univariate and multivariate tests, (ii) compared those who had an ARD with those who did not and (iii) compared those with an ARD who had one, two to four, and five or more admissions.

Methamphetamine use and technology-mediated psychosocial interventions: A mini-review.

Addict Behav 2021 Oct 23;121:106881. Epub 2021 Feb 23.

Turning Point, Eastern Health, 110 Church St., Richmond, VIC 3121, Australia; Monash Alfred Psychiatry Research Centre, Central Clinical School, Faculty of Medicine, Nursing and Health Sciences, Monash University, Melbourne, VIC 3004, Australia. Electronic address:

Engagement with face-to-face psychosocial interventions is often compromised in people using methamphetamine (MA), in the context of high rates of polysubstance use, mental health disorders, cognitive impairment and geographic isolation. Technology-mediated interventions offer flexible ways of engaging with treatment and are readily accessible. This mini-review evaluates evidence from eight studies for the effectiveness of telephone, mHealth (text-messaging and apps) and computer-based interventions for MA use. Read More

Methamphetamine seeking after prolonged abstinence is associated with activated projections from anterior intralaminar nucleus of thalamus to dorsolateral striatum in female rats.

Pharmacol Biochem Behav 2021 01 11;200:173087. Epub 2020 Dec 11.

Department of Psychology, University of Maryland College Park, College Park, MD 20742, United States of America. Electronic address:

Methamphetamine (Meth) seeking progressively increases after cessation from drug self-administration (incubation of Meth craving). We have previously shown that both dorsomedial and dorsolateral striatum (DMS and DLS) play critical roles in this incubation in male rats. Moreover, our recent anatomical tracing study examined afferent projections into DMS and demonstrated a novel role of projections from anterior intralaminar nucleus of thalamus (AIT) to DMS in incubation of Meth craving in male rats.

Vaccine development against methamphetamine drug addiction.

Expert Rev Vaccines 2020 12 10;19(12):1105-1114. Epub 2020 Dec 10.

Institute for Health and Sport, Victoria University , Melbourne, VIC, Australia.

Introduction: There are currently no effective treatments for Methamphetamine (METH) addiction and psychotherapy remains the sole treatment option. The development of immunopharmacotherapies for the treatment of drug addiction, overdose, and relapse management appears to be promising alternative and a significant body of information has been generated using various vaccine development strategies. Herein, we present an update on the developments toward anti-METH vaccines and their study outcomes in preclinical and clinical studies. Read More

Int J Mol Sci 2020 Nov 23;21(22). Epub 2020 Nov 23.

College of Pharmacy, Keimyung University, Daegu 42601, Korea.

Methamphetamine (MA) use disorder is a chronic neuropsychiatric disease characterized by recurrent binge episodes, intervals of abstinence, and relapses to MA use. Therefore, identification of the key genes and pathways involved is important for improving the diagnosis and treatment of this disorder. In this study, high-throughput RNA sequencing was performed to find the key genes and examine the comparability of gene expression between whisker follicles and the striatum of rats following MA self-administration.

Substance use disorders and chronic itch.

J Am Acad Dermatol 2021 Jan 3;84(1):148-155. Epub 2020 Sep 3.

Dr Phillip Frost Department of Dermatology and Miami Itch Center, University of Miami, Miami, Florida. Electronic address:

Chronic pruritus is one dermatologic manifestation of an underlying substance use disorder. Recent literature has uncovered similarities between the general neurologic mechanisms of addiction and chronic itch, largely involving activation of the dopaminergic reward circuits within the brain and imbalances between mu and kappa opioid receptor activation. It is likely that the use of specific drugs, like central nervous system stimulants and opioids, results in further activation and imbalances within these pathways, perpetuating both addiction and pruritus simultaneously.

Sustained attention and vigilance deficits associated with HIV and a history of methamphetamine dependence.

Drug Alcohol Depend 2020 10 22;215:108245. Epub 2020 Aug 22.

Department of Psychiatry, University of California San Diego, 9500 Gilman Drive MC 0804, La Jolla, CA, 92093-0804, United States; VA Center of Excellence for Stress and Mental Health, Veterans Administration San Diego HealthCare System, 3350 La Jolla Village Drive, San Diego, CA, 92161, United States.

Background: Human immunodeficiency virus (HIV)-associated neurocognitive disorders persist in the era of antiretroviral therapy. One factor that is elevated among persons with HIV (PWH) and independently associated with neurocognitive impairment is methamphetamine dependence (METH). Such dependence may further increase cognitive impairment among PWH, by delaying HIV diagnosis (and thus, antiretroviral therapy initiation), which has been posited to account for persistent cognitive impairment among PWH, despite subsequent treatment-related viral load suppression (VLS; <50 copies of the virus per milliliter in plasma or cerebrospinal fluid).

AMPed-up adolescents: The role of age in the abuse of amphetamines and its consequences on cognition and prefrontal cortex development.

Pharmacol Biochem Behav 2020 11 20;198:173016. Epub 2020 Aug 20.

Department of Psychology, University of Illinois at Urbana-Champaign, USA; Neuroscience Program, University of Illinois at Urbana-Champaign, USA; Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign, USA. Electronic address:

Adolescent use of amphetamine and its closely related, methylated version methamphetamine, is alarmingly high in those who use drugs for nonmedical purposes. This raises serious concerns about the potential for this drug use to have a long-lasting, detrimental impact on the normal development of the brain and behavior that is ongoing during adolescence. In this review, we explore recent findings from both human and laboratory animal studies that investigate the consequences of amphetamine and methamphetamine exposure during this stage of life.
