We assessed the prevalence, sociodemographic variables, mental health condition, and type of drug use associated with suicide behaviors among patients with substance use disorders (SUD). Studies in English published from January 1, 1995 to December 31, 2020 were searched on PubMed, Scopus, Cochrane and Web of Science to identify studies on variables associated with suicidal behaviors (ideations and attempts) among patients with SUD. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria: (i) population: patients with SUD; (ii) intervention: suicide behaviors in the past year; (iii) comparator: SUD who had not suicide behaviors; (iv) outcome: suicide ideations or attempts in the last year; and (v) study type: cross-sectional, cohort, and case-control studies...

To date, a limited number of pharmacological agents exist to treat alcohol use disorders (AUDs), and there is growing interest in new therapeutic tools. In this framework, topiramate may represent a useful treatment option, although its use is not yet approved for AUDs. The main focus of this review is to discuss all the existing data supporting the use of topiramate in AUDs, with an emphasis on the most recent and relevant clinical implications. In addition, the profile of the alcoholic patient who may benefit more from the use of topiramate is outlined...

BACKGROUND: Substantial concerns have been raised about the neuropsychiatric safety of the smoking cessation medications varenicline and bupropion. Their efficacy relative to nicotine patch largely relies on indirect comparisons, and there is limited information on safety and efficacy in smokers with psychiatric disorders. We compared the relative neuropsychiatric safety risk and efficacy of varenicline and bupropion with nicotine patch and placebo in smokers with and without psychiatric disorders...

OBJECTIVE: Research has suggested that subanesthetic doses of ketamine may work to improve cocaine-related vulnerabilities and facilitate efforts at behavioral modification. The purpose of this trial was to test whether a single ketamine infusion improved treatment outcomes in cocaine-dependent adults engaged in mindfulness-based relapse prevention. METHODS: Fifty-five cocaine-dependent individuals were randomly assigned to receive a 40-minute intravenous infusion of ketamine (0...

The opioid epidemic has increased hospital admissions for serious infections related to opioid abuse. Our findings demonstrate that addiction medicine consultation is associated with increased treatment for opioid use disorder (OUD), greater likelihood of completing antimicrobial therapy, and reduced readmission rates among patients with OUD and serious infections requiring hospitalization.

Opioid use disorder is characterised by the persistent use of opioids despite the adverse consequences of its use. The disorder is associated with a range of mental and general medical comorbid disorders, and with increased mortality. Although genetics are important in opioid use disorder, younger age, male sex, and lower educational attainment level and income, increase the risk of opioid use disorder, as do certain psychiatric disorders (eg, other substance use disorders and mood disorders). The medications for opioid use disorder, which include methadone, buprenorphine, and extended-release naltrexone, significantly improve opioid use disorder outcomes...

OBJECTIVE: The current meta-analysis synthesizes previous findings on the effect of gabapentin on alcohol withdrawal and craving. DATA SOURCES: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, a search for relevant English-language literature published between January 1999 and February 2019 was conducted using PubMed and Google Scholar with the keywords alcohol use disorder, alcohol dependence, alcohol withdrawals, alcohol craving, "gabapentin in alcohol use, consumption," and "gabapentin in alcohol withdrawals...

BACKGROUND: Benzodiazepines are used to treat alcohol withdrawal (AW) but cause cognitive impairment, sedation, and ataxia, and interact with alcohol. Nonbenzodiazepine anticonvulsants are promising and possibly safer alternatives for the treatment of AW. OBJECTIVE: To compare follow-up measures of Epworth Sleepiness Scale (ESS), Penn Alcohol Craving Scale (PACS), ataxia rating, and Clinical Institute Withdrawal Assessment for Alcohol revised (CIWA-Ar) symptoms between alcohol-dependent individuals randomized to treatment with gabapentin or chlordiazepoxide...

Alcohol misuse is the fifth leading risk factor for premature death and disability worldwide. Fewer than 10% of afflicted Americans receive pharmacological treatment for alcohol use disorder. Gabapentin is a calcium channel GABAergic modulator that is widely used for pain. Studies showing reduced drinking and decreased craving and alcohol-related disturbances in sleep and affect in the months following alcohol cessation suggest therapeutic potential for alcohol use disorder. Areas covered: Human laboratory and clinical studies assessing gabapentin for alcohol use disorder are reviewed...

Gabapentin was compared with phenobarbital for the treatment of alcohol withdrawal in a randomized, open-label, controlled trial in 27 inpatients. There were no significant differences in the proportion of treatment completers between treatment groups or the proportion of patients in each group requiring rescue medication for breakthrough signs and symptoms of alcohol withdrawal. There were no significant treatment differences in withdrawal symptoms or psychological distress, nor were there serious adverse events...

INTRODUCTION: Some anticonvulsants ameliorate signs and symptoms of alcohol withdrawal, but have an unacceptable side effect burden. Among the advantages of using anticonvulsant agents in this capacity is their purported lack of interaction with alcohol that could increase psychomotor deficits, increase cognitive impairment, or increase intoxication. The aim of this study was to evaluate alcohol use and symptom reduction of gabapentin when compared with lorazepam in the treatment of alcohol withdrawal in a double-blinded randomized clinical trial...

STUDY OBJECTIVE: Gabapentin has been proved to be beneficial in promoting abstinence, decreasing alcohol cravings, and improving mood and sleep quality when given at higher doses; however, data are limited regarding the efficacy and safety of using high-dose gabapentin as part of the treatment of alcohol withdrawal syndrome (AWS). The aim of this study was to evaluate the impact of high-dose gabapentin on benzodiazepine requirements, alcohol withdrawal symptoms, and hospital length of stay in patients hospitalized with AWS...

Methamphetamine (MA) use disorder is a serious psychiatric condition for which there are no FDA-approved medications. Naltrexone (NTX) is an opioid receptor antagonist with demonstrated efficacy, albeit moderate, for the treatment of alcoholism and opioid dependence. Preclinical and clinical studies suggest that NTX may be useful for the treatment of MA use disorder. To inform treatment development, we conducted a double-blind, randomized, crossover, placebo-controlled human laboratory study of NTX. Non-treatment-seeking individuals meeting DSM-IV criteria for MA abuse or dependence (n=30) completed two separate 5-day inpatient stays...

OBJECTIVE: To review the literature evaluating gabapentin for alcohol withdrawal and dependence. DATA SOURCES: A literature search of MEDLINE (1966 to end of March 2015) and PubMed was performed using the terms alcohol, gabapentin, withdrawal, and dependence. Additional references were identified from a review of literature citations. STUDY SELECTION AND DATA EXTRACTION: English-language prospective studies evaluating gabapentin for alcohol withdrawal and dependence were evaluated...

Alcohol consumption level and alcohol use disorder (AUD) diagnosis are moderately heritable traits. We conduct genome-wide association studies of these traits using longitudinal Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) scores and AUD diagnoses in a multi-ancestry Million Veteran Program sample (N = 274,424). We identify 18 genome-wide significant loci: 5 associated with both traits, 8 associated with AUDIT-C only, and 5 associated with AUD diagnosis only. Polygenic Risk Scores (PRS) for both traits are associated with alcohol-related disorders in two independent samples...

OBJECTIVE: Although cannabis is an illegal drug, 'medical marijuana programs' (MMPs) have proliferated (e.g., in Canada and several US states), allowing for legal cannabis use for therapeutic purposes. While both health risks and potential therapeutic benefits for cannabis use have been documented, potential public health impacts of MMPs - also vis-à-vis other psychoactive substance use - remain under-explored. METHODS: We briefly reviewed the emerging evidence on MMP participants' health status, and specifically other psychoactive substance use behaviors and outcomes...

Existent profiles of Medical Marijuana Program (MMP) participants indicate common and co-morbid chronic diseases, yet evidence on disability or functioning as well as comparisons with general populations are largely lacking. This study compared health, substance use, and functioning status among formally approved MMP participants with the general adult population in Ontario (Canada). A community-recruited sample (n = 53) of MMP participants was compared to a sub-sample (n = 510) of the representative Centre for Addiction and Mental Health (CAMH) Monitor (2015 cycle) survey of Ontario general population adults (ages 18+) based on identical telephone-based interviews regarding substance use, health, and functioning measures...

Alcohol policy in North America is dominated by moderation and abstinence-based modalities that focus on controlling population-level alcohol consumption and modifying individual consumption patterns to prevent and reduce alcohol-related harms. However, conventional alcohol policies and interventions do not adequately address harms associated with high-risk drinking among individuals experiencing severe alcohol use disorder (AUD) and structural vulnerability such as poverty and homelessness. In this commentary we address this gap in alcohol harm reduction, and highlight the lack of, and distinct need for, alcohol-specific harm reduction for people experiencing structural vulnerability and severe AUD...

BACKGROUND: Extended-release naltrexone (XR-NTX), an opioid antagonist, and sublingual buprenorphine-naloxone (BUP-NX), a partial opioid agonist, are pharmacologically and conceptually distinct interventions to prevent opioid relapse. We aimed to estimate the difference in opioid relapse-free survival between XR-NTX and BUP-NX. METHODS: We initiated this 24 week, open-label, randomised controlled, comparative effectiveness trial at eight US community-based inpatient services and followed up participants as outpatients...
