Andrew Johansen, Lisa M McFadden
BACKGROUND: Methamphetamine (METH) is an addictive substance that is used in both males and females. Few preclinical studies have focused on understanding sex-differences in the neurochemical consequences of contingent METH. The purpose of the current study was to investigate potential sex-differences in the neurochemical consequences of METH self-administration. METHODS: Male and female adult rats were given extended access to METH or saline self-administration for 7d...

Repeated exposure to stress during childhood is associated with increased risk for neuropsychiatric illness, substance use disorders and other behavioral problems in adulthood. However, it is not clear how chronic childhood stress can lead to emergence of such a wide range of symptoms and disorders in later life. One possible explanation lies in stress-induced disruption to the development of specific brain regions associated with executive function and reward processing, deficits in which are common to the disorders promoted by childhood stress...

It is widely accepted that alcohol and other drug consumption is profoundly gendered. Just where this gendering is occurring, however, remains the subject of debate. We contend that one important and overlooked site where the gendering of substance consumption and addiction is taking place is through AOD research itself: in particular, through the addiction screening and diagnostic tools designed to measure and track substance consumption and problems within populations. These tools establish key criteria and set numerical threshold scores for the identification of problems...

BACKGROUND: Deliberate self-harm (DSH) causes important concern in prison inmates as it worsens morbidity and increases the risk for suicide. The aim of the present study is to investigate the prevalence and correlates of DSH in a large sample of male prisoners. METHODS: A cross-sectional study evaluated male prisoners aged 18+ years. Current and lifetime psychiatric diagnoses were assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders - DSM-IV Axis I and Axis II Disorders and with the Addiction Severity Index-Expanded Version...

BACKGROUND: As part of an ongoing initiative by the Malaysian government to implement alternative approaches to involuntary detention of people who use drugs, the National Anti-Drug Agency has created new voluntary drug treatment programs known as Cure and Care (C&C) Centers that provide free access to addiction treatment services, including methadone maintenance therapy, integrated with social and health services. OBJECTIVES:   We evaluated early treatment outcomes and client satisfaction among patients accessing C&C treatment and ancillary services at Malaysia's second C&C Center located in Kota Bharu, Kelantan...

Despite having disproportionately high rates of substance use disorder and co-occurring health and mental health issues compared to the general population, transgender individuals experience significant barriers to accessing and engaging in addiction treatment programs. Inpatient addiction treatment centers were originally designed to treat substance-dependent heterosexual cisgender populations and, as such, feature gender-segregated housing, bathrooms, and treatment sessions. The heteronormative structural and programmatic barriers, combined with exposures to stigmatic and prejudicial attitudes, may dissuade transgender populations from benefiting from the addiction treatment they so direly need...

Impulsive-compulsive disorders in Parkinson's disease patients have been described as behavioural or substance addictions including pathological gambling or compulsive medication use of dopamine replacement therapy. A substantial gap remains in the understanding of these disorders. We previously demonstrated that the rewarding effect of the D2/D3 agonist pramipexole was enhanced after repeated exposure to L-dopa and alpha-synuclein mediated dopaminergic nigral loss with specific transcriptional signatures suggesting a key involvement of the glutamatergic pathway...

The current narrative describing the national opioid epidemic as the result of overprescribing opioid pain medicines fails to capture the full dimensions of problem and leads to inadequate and even confounding solutions. Overlooked is the fact that polysubstance use is nearly ubiquitous among overdose deaths, demonstrating that the opioid overdose death problem is bigger than opioids. The foundation of the nation's opioid overdose crisis - and the totality of the nation's drug epidemic - is widespread recreational pharmacology, the use of drugs for fun or "self-medication...

Limited human studies have directly tested the dissociation between wanting and liking with human substance users, a core tenet of the Incentive Sensitisation Theory (IST). The aim of this study is to test the dissociation between wanting and liking in humans across two commonly used licit substances, alcohol and caffeine. The STRAP-R (Sensitivity To Reinforcement of Addictive and other Primary Rewards) questionnaire was administered to 285 alcohol users (mean age=33.30, SD= 8.83) and 134 coffee users (mean age=33...

The last thirty years have been very prosperous in the field of liver transplantation (LT), with great advances in organ conservation, surgical techniques, peri-operative management and long-term immunosuppression, resulting in improved patient and graft survival rates as well as quality of life. However, substance addiction after LT, namely alcohol and tobacco, results in short term morbidity together with medium and long-term mortality. The main consequences can be vascular (increased risk of hepatic artery thrombosis in smokers), hepatic (recurrent alcoholic cirrhosis in alcohol relapsers) and oncological (increased risk of malignancy in patients consuming tobacco and/or alcohol after LT)...

While guidelines advise integrated treatment of patients with substance use disorder (SUD) and posttraumatic stress disorder (PTSD), recent studies and reviews find no convincing evidence of different outcomes following treatment between non-trauma focused integrated programs and SUD treatment alone. In this study, we analyzed whether SUD patients with higher levels of PTSD symptoms receiving standard, non-integrated SUD treatment (N=145) differed in outcomes compared to patients with lower levels of PTSD symptoms (N=152)...

BACKGROUND: Compulsive buying disorder (CBD) is a condition characterized by excessive preoccupations, impulses, and behaviors regarding buying, resulting in serious psychological, social, and financial problems. Even though it has not been included in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, "behavioral addictions" section, CBD is a hot topic in current clinical psychiatry, because of its relevant prevalence (at least 5% in adult populations) and severe effect on quality of life...

The link between early initiation and problematic use has been observed for substance use disorders; however, this link has not been as clearly established for Internet gaming disorder (IGD). Available studies indicate that individuals who initiate Internet use at younger ages exhibit an increased risk for general Internet addiction. Prior research also suggests unique cognitive processes in online gaming, such that an individual's overall sense of self-worth can become contingent upon self-esteem derived from the gaming environment...

OBJECTIVES: The objectives of this study are to describe marijuana use in Canada and explore factors associated with problematic use. METHODS: Data from the 2010-2012 circulations of the Canadian Alcohol and Drug Use Monitoring Survey were used to create three logistic regression models for the purposes of identifying and comparing factors associated with the degree of marijuana use, as determined via the WHO Alcohol, Smoking and Substance Abuse Involvement Screening Test (non-problematic, problematic) and European Monitoring Centre for Drugs and Drug Addiction (experiential, recent, current) methods...

Substance abuse and addiction are worldwide concerns. In China, populated with over 1.3 billion people, emerging studies show a steady increase in substance abuse and substance-related problems. Some of the major challenges include a lack of an effective evaluation platform to determine the health status of substance-addicted subjects. It is known that the intestinal microbiota is associated to the occurrence and development of human diseases. However, the changes of bacterial diversity of intestinal microbiota in substance-addicted subjects have not been clearly characterized...

OBJECTIVE: Over the past 5 years, a shift to the use of novel psychoactive substances (NPS) has been observed among opioid users. The aim of this study was to assess the potential reasons for NPS use among treatment-seeking patients receiving opiate substitution therapy. METHOD: A structured questionnaire was filled out by a sample of 198 opiate dependent patients of Hungary's National Institute of Psychiatry and Addiction. This questionnaire assessed demographics, treatment characteristics, lifetime substance use, potential reasons for NPS use, negative life events (Life Events Scale), and psychiatric symptoms (Brief Symptom Inventory)...

Although each state in the United States legally authorizes involuntary civil commitment on the grounds of severe mental illness, a considerable number do not have comparable laws to mandate drug addiction treatment. This discrepancy is due, in part, to differing ethical positions regarding whether a substance use disorder diagnosis provides sufficient justification to suspend individual liberty rights. This article chronicles some of the legal and ethical thinking on the subject and applies them to a social work-specific context...

BACKGROUND: Policymakers frequently mandate that employers or insurers provide insurance benefits deemed to be critical to individuals' well-being. However, in the presence of private market imperfections, mandates that increase demand for a service can lead to price increases for that service, without necessarily affecting the quantity being supplied. We test this idea empirically by looking at mental health parity mandates. OBJECTIVE: This study evaluated whether implementation of parity laws was associated with changes in mental health provider wages...
