Importance: Stimulant use disorder is common, affecting between 0.3% and 1.1% of the population, and costs more than $85 billion per year globally. There are no licensed treatments to date. Several lines of evidence implicate the dopamine system in the pathogenesis of substance use disorder. Therefore, understanding the nature of dopamine dysfunction seen in stimulant users has the potential to aid the development of new therapeutics. Objective: To comprehensively review the in vivo imaging evidence for dopaminergic alterations in stimulant (cocaine, amphetamine, or methamphetamine) abuse or dependence...

BACKGROUND: Strategies are needed to identify youth developing schizophrenia. The present study aimed to determine whether adolescents treated for substance misuse were at elevated risk to develop schizophrenia, whether this risk has changed since the late 1960s, and whether substance misuse in adolescence predicted poorer outcomes through adulthood. METHOD: In a Swedish city, since the mid-1960s there has been only one clinic for adolescent substance misuse. Three samples from this clinic were studied: 1992 individuals treated from 1968 to 1971 followed to age 50 years; 1576 treated from 1980 to 1984 followed to age 35 years; and 180 treated in 2004 followed to age 22 years...

BACKGROUND: Substance use and affective disorders frequently co-occur, but the role of affective dysregulation in addiction is often overlooked. There is evidence shows that substance - dependent individuals have more problems in regulating their emotions. OBJECTIVES: This study compared two commonly used emotional regulation strategies, cognitive reappraisal and suppression, in opioids and methamphetamine dependents. MATERIALS AND METHODS: One hundred forty men with substance dependence (70 Opioids, 70 Methamphetamine) were selected by accessible sampling, and they responded to Emotion Regulation Questionnaire (Gross & John) and Clinical drug addiction profile (CDAP) questionnaire...

BACKGROUND: Individuals who use methamphetamine chronically exhibit emotional and dopaminergic neurochemical deficits. Although the amygdala has an important role in emotion processing and receives dopaminergic innervation, little is known about how dopamine transmission in this region contributes to emotion regulation. This investigation aimed to evaluate emotion regulation in subjects who met DSM-IV criteria for methamphetamine dependence, and to test for a relationship between self-reports of difficulty in emotion regulation and D2-type dopamine receptor availability in the amygdala...

Drug craving is an important motivational phenomenon among addicted individuals, and successful management of craving is essential to both the initiation and maintenance of abstinence. Although craving in response to drug cues is common in drug-dependent individuals, it is not universal. At the present time, it is not known why approximately 20-30% of all addicted persons fail to report appreciable craving in laboratory-based cue reactivity studies. This study examined the possibility that alexithymia, a personality attribute characterized by a difficulty identifying and describing emotions, may contribute to the impoverished cue-elicited craving experienced by some addicts...

BACKGROUND: Amphetamine and methamphetamine use disorders are associated with severe health and social consequences. No pharmacological therapy has been approved for the treatment of these disorders. Psychostimulants can act as maintenance-like therapies for managing substance use among these patients. The aim of this study is to evaluate the literature examining the efficacy and safety of psychostimulant agents for increasing abstinence and treatment retention among patients with amphetamine and methamphetamine use disorders...

BACKGROUND: Impulsivity has been proposed as an important factor in the initiation and maintenance of addiction. Indirect evidence suggests that some methamphetamine users report less impulsivity when they are using methamphetamine compared to when abstaining from drug use, but this hypothesis has not been directly tested. OBJECTIVES/METHODS: In this study, self-reports of impulsivity were obtained from 32 methamphetamine-dependent (DSM-IV) research participants and 41 healthy control subjects, using the Barratt Impulsiveness Scale-11...

Illicit methamphetamine abuse represents a major problem in many countries worldwide, including the United States. Prolonged regular smoking or injection of methamphetamine can cause a psychosis, typically characterized by paranoid delusions and auditory hallucinations and often associated with disturbances in mood. These symptoms may persist long after methamphetamine is discontinued and may prove refractory to antipsychotic medications. The authors describe a patient who developed a typical methamphetamine psychosis that persisted despite months of abstinence from methamphetamine and weeks of treatment with antipsychotic medication but that responded promptly to electroconvulsive therapy (ECT) on two separate occasions: on initial presentation and again a year later when the patient relapsed into methamphetamine abuse and developed psychosis again...

AIMS: Two previous randomized trials found an effect for bupropion in reducing methamphetamine use in the subgroup with lower frequency of methamphetamine use at baseline. This study aimed to replicate these results by comparing bupropion versus placebo in methamphetamine-dependent participants with less than daily methamphetamine use at baseline. METHODS: Methamphetamine-dependent volunteers reporting methamphetamine use on ≤29 of past 30 days were randomized to bupropion 150 mg twice daily (n = 41) or placebo (n = 43) and out-patient counseling for 12 weeks...

Craving for addictive drugs may predict relapse in abstinent addicts. To assess relationships between craving and use, we examined changes in craving for methamphetamine (MA) in a sample of 865 outpatients in a multisite 16-week MA-treatment study. Craving was assessed on a 0-100 scale, and MA use was assessed by self-report and confirmed by urinalysis. We hypothesized that the magnitude of craving would decline (decay) with increased time of abstinence, and that decay would be greater for more frequent MA users, and greater for intravenous (IV) users and smokers as compared to those who used MA intranasally...

BACKGROUND: This paper reports data from a study designed to determine the impact of an 8-week exercise program on depression and anxiety symptoms among newly abstinent methamphetamine (MA)-dependent individuals in residential treatment. METHODS: One hundred thirty-five MA-dependent individuals, newly enrolled in residential treatment, were randomly assigned to receive either a 3-times-per-week, 60-minute structured exercise program for 8 weeks (24 sessions) or an equivalent number of health education sessions...

AIMS: Withdrawal symptoms have been linked to a propensity for relapse to drug abuse. Inasmuch as this association applies to methamphetamine (MA) abuse, an understanding of the course of MA withdrawal symptoms may help to direct treatment for MA dependence. Previous studies of symptoms manifested during abstinence from MA have been limited in size and scope. We asked (i) whether debilitating psychological and/or physical symptoms appear during the first several weeks of MA abstinence, (ii) how craving for MA evolves and (iii) whether psychiatric symptoms (e...

OBJECTIVE: People experiencing a first episode of psychosis frequently have co-occurring substance use disorders, usually involving alcohol and cannabis, which put them at risk for prolonged psychosis, psychotic relapse, and other adverse outcomes. Yet few studies of first-episode psychosis have addressed the course of substance use disorders and the response to specialized substance abuse treatments. METHODS: The authors searched MEDLINE, PsycINFO, and other medical databases for English-language articles published between 1990 and 2009...

Psychotic symptoms and syndromes are frequently experienced among individuals who use methamphetamine, with recent estimates of up to approximately 40 % of users affected. Although transient in a large proportion of users, acute symptoms can include agitation, violence, and delusions, and may require management in an inpatient psychiatric or other crisis intervention setting. In a subset of individuals, psychosis can recur and persist and may be difficult to distinguish from a primary psychotic disorder such as schizophrenia...

BACKGROUND: To determine the factors involved in violent behavior in patients with bipolar disorder (BD) and to investigate the relationship between violence and substance use disorder (SUD). METHODS: A sample of 100 male inpatients diagnosed with BD type I who were experiencing a current mood episode participated in the study. Violent behavior was defined as physical aggression against others. All patients were evaluated using the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HDRS), Positive and Negative Syndrome Scale-positive subscale (PANSS-p), Barratt Impulsivity Scale-11 (BIS-11), Buss-Perry Aggression Questionnaire (BPAQ) and Overt Aggression Scale (OAS)...

The National Institute on Drug Abuse Clinical Trials Network launched the Prescription Opioid Addiction Treatment Study (POATS) in response to rising rates of prescription opioid dependence and gaps in understanding the optimal course of treatment for this population. POATS employed a multi-site, two-phase adaptive, sequential treatment design to approximate clinical practice. The study took place at 10 community treatment programs around the United States. Participants included men and women age > or =18 who met Diagnostic and Statistical Manual, 4th Edition criteria for dependence upon prescription opioids, with physiologic features; those with a prominent history of heroin use (according to pre-specified criteria) were excluded...

BACKGROUND: Historically, smoking cessation was thought to negatively impact substance use outcomes among smokers who use other substances. We sought to synthesize recent reports on this association. METHODS: Google Scholar, PubMed, and Cinahl were searched for studies published from 2006 to March 29, 2016 that reported impact of smoking cessation treatment or quitting smoking on substance use or substance use disorder treatment outcomes in the general population and among those in substance abuse treatment...

OBJECTIVE: Attitudes toward marijuana are changing, the prevalence of DSM-IV cannabis use disorder has increased, and DSM-5 modified the cannabis use disorder criteria. Therefore, updated information is needed on the prevalence, demographic characteristics, psychiatric comorbidity, disability, and treatment for DSM-5 cannabis use disorder. METHOD: In 2012-2013, 36,309 participants ≥18 years old were interviewed in the National Epidemiologic Survey on Alcohol and Related Conditions-III...

Both depression and substance use disorders represent major global public health concerns and are often co-occurring. Although there are ongoing discoveries regarding the pathophysiology and treatment of each condition, common mechanisms and effective treatments for co-occurring depression and substance abuse remain elusive. Mindfulness training has been shown recently to benefit both depression and substance use disorders, suggesting that this approach may target common behavioral and neurobiological processes...
