Aims: Pathological gambling (PG) shares diagnostic features with substance use disorder (SUD), but the neurochemical mechanisms underlying PG are poorly understood. Because dopamine (DA), a neurotransmitter implicated in reward and reinforcement, is probably involved, we used positron emission tomography (PET) to test whether PG is associated with abnormalities in D2 and D3 receptor levels, as observed in SUD.
Design: Case-control study comparing PG to healthy control (HC) subjects.
Setting: Academic research imaging centre.
Participants: Thirteen non-treatment-seeking males meeting DSM-IV criteria for PG, and 12 matched HC (11 of whom completed PET).
Measurements: Two PET scans (one with the D3 receptor preferring agonist [11C]-(+)-propyl-hexahydro-naphtho-oxazin (PHNO) and the other with [11C]raclopride) to assess D(2/3) DA receptor availability, and behavioural measures (self-report q…

Problem gambling and intimate partner violence.
This study examined the prevalence and severity of intimate partner violence (IPV) among 248 problem gamblers (43 women, 205 men) recruited from newspaper advertisements. The main outcome measures used were the Canadian Problem Gambling Index, the Conflicts Tactics Scale-2, the State Trait Anger Expression Inventory-2, the drug and alcohol section of the Addiction Severity Index and the substance use section of the Structured Clinical Interview for the DSM-IV. In this sample, 62.9% of participants reported perpetrating and/or being the victims of IPV in the past year, with 25.4% reporting perpetrating severe IPV. The majority of the sample (64.5%) also had clinically significant anger problems, which was associated with an increased risk of being both the perpetrator and victim of IPV. The presence of a lifetime substance use disorder among participants who had clinically significant ang…

Oral delta-9-tetrahydrocannabinol suppresses cannabis withdrawal symptoms.
Background: This study assessed whether oral administration of delta-9-tetrahydrocannbinol (THC) effectively suppressed cannabis withdrawal in an outpatient environment. The primary aims were to establish the pharmacological specificity of the withdrawal syndrome and to obtain information relevant to determining the potential use of THC to assist in the treatment of cannabis dependence.
Method: Eight adult, daily cannabis users who were not seeking treatment participated in a 40-day, within-subject ABACAD study. Participants administered daily doses of placebo, 30 mg (10 mg/tid), or 90 mg (30 mg/tid) oral THC during three, 5-day periods of abstinence from cannabis use separated by 7-9 periods of smoking cannabis as usual.
Results: Comparison of withdrawal symptoms across conditions indicated that (1) the lower dose of THC reduced withdrawal discomfort, and (2) the higher dose produced ad…

Neuropsychological functioning in adolescent marijuana users: subtle deficits detectable after a month of abstinence.
In adults, studies examining the long-lasting cognitive effects of marijuana use demonstrate subtle deficits in attention, executive function, and memory. Because neuromaturation continues through adolescence, these results cannot necessarily generalize to adolescent marijuana users. The goal of this study was to examine neuropsychological functioning in abstinent marijuana using and demographically similar control adolescents. Data were collected from 65 adolescent marijuana users (n=31, 26% females) and controls (n=34, 26% females) 16-18 years of age. Extensive exclusionary criteria included independent psychiatric, medical, and neurologic disorders. Neuropsychological assessments were conducted after>23 days of monitored abstinence. After controlling for lifetime alcohol use and depressive symptoms, adolescent marijuana users demonstrated slower psychomotor speed (p<.05), and poorer c…

Altered resting-state functional connectivity of the insula in young adults with Internet gaming disorder.
The insula has been implicated in salience processing, craving, and interoception, all of which are critical to the clinical manifestations of drug and behavioral addiction. In this functional magnetic resonance imaging (fMRI) study, we examined resting-state functional connectivity (rsFC) of the insula and its association with Internet gaming characteristics in 74 young adults with Internet gaming disorder (IGD) and 41 age- and gender-matched healthy control subjects (HCs). In comparison with HCs, IGD subjects (IGDs) exhibited enhanced rsFC between the anterior insula and a network of regions including anterior cingulate cortex (ACC), putamen, angular gyrus, and precuneous, which are involved in salience, craving, self-monitoring, and attention. IGDs also demonstrated significantly stronger rsFC between the posterior insula and postcentral gyrus, precentral gyrus, supplemental motor are…

Spirituality-based recovery from drug addiction in the twelve-step fellowship of narcotics anonymous.
Background: Narcotics Anonymous is a worldwide fellowship that employs the Twelve-Step model for members dependent on drugs of abuse. The spiritual orientation of its program of abstinence has not been subjected to empirical study.
Methods: Responses of 527 American Narcotics Anonymous meeting attendees to a structured questionnaire were evaluated for the roles of cognitive and psychosocial aspects of spirituality in their recovery.
Results: Respondents had last used drugs or alcohol on average 6.1 years previously. They were found to be more oriented toward a spiritual than a formally religious orientation than probability samples of the general population. Aspects of membership such as affiliation toward other members and the experience of spiritual awakening were associated with lower rates of drug or alcohol craving, whereas scores on depression were associated with higher craving sc…

Mindful attention reduces neural and self-reported cue-induced craving in smokers.
An emerging body of research suggests that mindfulness-based interventions may be beneficial for smoking cessation and the treatment of other addictive disorders. One way that mindfulness may facilitate smoking cessation is through the reduction of craving to smoking cues. The present work considers whether mindful attention can reduce self-reported and neural markers of cue-induced craving in treatment seeking smokers. Forty-seven (n = 47) meditation-naïve treatment-seeking smokers (12-h abstinent from smoking) viewed and made ratings of smoking and neutral images while undergoing functional magnetic resonance imaging (fMRI). Participants were trained and instructed to view these images passively or with mindful attention. Results indicated that mindful attention reduced self-reported craving to smoking images, and reduced neural activity in a craving-related region of subgenual anterio…

Background and aims: Mood and cognition alterations play a role in the motivation for alcohol-drinking. Lipopolysaccharides are known to stimulate inflammation that was shown to induce mood and cognitive changes in rodents and humans. Enhanced intestinal permeability and elevated blood LPS characterize alcohol-dependent mice. However, no data have been published in non-cirrhotic humans. Our first goal was to test whether intestinal permeability, blood LPS and cytokines are increased in non-cirrhotic alcohol-dependent subjects before withdrawal and if they recover after withdrawal. Our second goal was to test correlations between these biochemical and the behavioral variables to explore the possibility of a role for a gut-brain interaction in the development of alcohol-dependence.
Methods: Forty alcohol-dependent-subjects hospitalized for a 3-week detoxification program were tested at ons…

Predicting dropout in the first 3 months of 12-step residential drug and alcohol treatment in an Australian sample.
Objective: Premature termination from treatment is a major factor associated with poorer drug and alcohol treatment outcomes. The present study investigated client-related baseline predictors of dropout at 3 months from a faith-based 12-step residential drug treatment program.
Method: Data were collected over a period of 14 months from eight residential drug and alcohol treatment programs run by The Australian Salvation Army. The final sample consisted of 618 participants, including 524 men (84.8%) and 94 women (15.2%). Predictor variables of interest were age, gender, primary drug of concern, criminal involvement, psychological distress, drug cravings, self-efficacy to abstain, spirituality, forgiveness of self and others, and life purpose. At 3 months, 264 participants (42.7%) remained in the treatment program, and 354 participants (57.3%) had dropped out.
Results: Binary logistic regr…

Evidence that 'food addiction' is a valid phenotype of obesity.
There is growing evidence of 'food addiction' (FA) in sugar- and fat-bingeing animals. The purpose of this study was to investigate the legitimacy of this disorder in the human condition. It was also our intention to extend the validation of the Yale Food Addiction Scale (YFAS) - the first tool developed to identify individuals with addictive tendencies towards food. Using a sample of obese adults (aged 25-45 years), and a case-control methodology, we focused our assessments on three domains relevant to the characterization of conventional substance-dependence disorders: clinical co-morbidities, psychological risk factors, and abnormal motivation for the addictive substance. Results were strongly supportive of the FA construct and validation of the YFAS. Those who met the diagnostic criteria for FA had a significantly greater co-morbidity with Binge Eating Disorder, depression, and atten…

Background and aims: Gambling disorder (GD) is a behavioral addiction often co-occurring with various mental health concerns, such as problematic pornography use (PPU). The specific impact of the co-occurrence of GD and PPU on treatment outcome remains underexplored. This study aimed to compare the treatment outcomes of individuals actively receiving treatment for GD (n = 172; 3.49% females), distinguishing between those without PPU (n = 146) and those with co-occurring GD and PPU (n = 26).
Methods: Cognitive-behavioral therapy (CBT) was administered in 16 weekly sessions, with assessments of GD severity, impulsivity, emotion regulation, psychopathology, and personality. Dropout, relapses, number of sessions attended, number of relapses, and amount of money spent during relapses were assessed as the main treatment outcomes.
Results: Patients with co-occurring GD and PPU showed greater GD…

Estimated Reductions in Opioid Overdose Deaths With Sustainment of Public Health Interventions in 4 US States.
Importance: In 2021, more than 80 000 US residents died from an opioid overdose. Public health intervention initiatives, such as the Helping to End Addiction Long-term (HEALing) Communities Study (HCS), are being launched with the goal of reducing opioid-related overdose deaths (OODs).
Objective: To estimate the change in the projected number of OODs under different scenarios of the duration of sustainment of interventions, compared with the status quo.
Design, setting, and participants: This decision analytical model simulated the opioid epidemic in the 4 states participating in the HCS (ie, Kentucky, Massachusetts, New York, and Ohio) from 2020 to 2026. Participants were a simulated population transitioning from opioid misuse to opioid use disorder (OUD), overdose, treatment, and relapse. The model was calibrated using 2015 to 2020 data from the National Survey on Drug Use and Health, …

Needs affordance as a key factor in likelihood of problematic social media use: Validation, latent Profile analysis and comparison of TikTok and Facebook problematic use measures.
Despite increasing concerns of maladaptive cognitive responses associated with social media, estimates of its prevalence are lacking in the literature. Further, existing studies have disproportionately focused on Facebook, while ignoring the penetration of TikTok and concerns of associated maladaptive behaviors. This study aims to 1) validate scale measures for problematic Facebook and TikTok use (PFU and PTTU) 2) comparatively assess the underlying cognitive pathways of the PFU and PTTU among a sample of university students, 3) determine the cut-off score of the PTTU assessment scale using Latent Profile Analysis (LPA) and 4) evaluate the contribution of specific criteria in the diagnosis of PTTU. The scales used to assess PFU and PTTU were found to have appropriate psychometric properties. The scores between the PFU and PTTU scales were found to be strongly associated, however, the rel…

Processing incomplete questionnaire data into continuous digital biomarkers for addiction monitoring.
Purpose: eHealth systems allow efficient daily smartphone-based collection of self-reported data on mood, wellbeing, routines, and motivation; however, missing data is frequent. Within addictive disorders, missing data may reflect lack of motivation to stay sober. We hypothesize that qualitative questionnaire data contains valuable information, which after proper handling of missing data becomes more useful for practitioners.
Methods: Anonymized data from daily questionnaires containing 11 questions was collected with an eHealth system for 751 patients with alcohol use disorder (AUD). Two digital continuous biomarkers were composed from 9 wellbeing questions (WeBe-i) and from two questions representing motivation/self-confidence to remain sober (MotSC-i). To investigate possible loss of information in the process of composing the digital biomarkers, performance of neural networks to pred…

Despite decades of research on neurobiological mechanisms of psychostimulant addiction, the only effective treatment for many addicts is contingency management, a behavioral treatment that uses alternative non-drug reward to maintain abstinence. However, when contingency management is discontinued, most addicts relapse to drug use. The brain mechanisms underlying relapse after cessation of contingency management are largely unknown, and, until recently, an animal model of this human condition did not exist. Here we used a novel rat model, in which the availability of a mutually exclusive palatable food maintains prolonged voluntary abstinence from intravenous methamphetamine self-administration, to demonstrate that the activation of monosynaptic glutamatergic projections from anterior insular cortex to central amygdala is critical to relapse after the cessation of contingency management.…

Exercise during early, but not late abstinence, attenuates subsequent relapse vulnerability in a rat model.
Exercise has shown promise as a nonpharmacological intervention for addiction, with evidence suggesting a potential utility for relapse prevention. In humans, exercise as an intervention is typically introduced well after the initiation of abstinence, yet neurobiological data from preclinical studies suggest that it may be more effective if initiated during early abstinence. Here, using rat models, we determined whether the beneficial effects of exercise on relapse vulnerability depends on when exercise is first initiated, during early versus late abstinence. Once rats (n=47) acquired cocaine self-administration, they were given 24-h access to cocaine (1.5 mg/kg per infusion) under a discrete trial procedure (four infusions per hour) for 10 days. The rats then began a 14-day abstinence period in which they had access (2 h per day) to a locked wheel throughout abstinence (sedentary) or an…

Psychological and physiological stress negatively impacts early engagement and retention of opioid-dependent individuals on methadone maintenance.
The present study investigated whether psychological and/or physiological measures of stress would impede induction onto methadone maintenance and predict early (<6 months) discontinuation. Compared with controls, opioid-dependent subjects displayed increased distress on the perceived stress scale (PSS) and post-traumatic stress disorder checklist (PCLC); 60% exhibited abnormal cortisol. Addiction severity index (ASI), drug-use, and stress indices explained between 17 and 37% of the variance in engagement including attendance, opioid abstinence, and methadone stabilization. Participants who discontinued treatment displayed poor engagement, abnormal cortisol, elevated withdrawal symptoms, higher distress, and increased ongoing opioid use versus compliant individuals. Discontinuation was initially related to drug-use severity; however, by 6 months, retention depended primarily upon cortiso…

Protective factors against relapse for practicing nurse anesthetists in recovery from anesthetic opiate dependency.
This qualitative inquiry explored factors that protect recovering anesthetic opioid-dependent nurse anesthetists from relapse after their return to anesthesia practice. Practicing nurse anesthetists in recovery from potent opioids were recruited through online advertising and individually interviewed over the telephone. The interview consisted of open-ended questions that aided description of personal experience of individual factors. Content analysis of the interviews revealed an overarching theme of a commitment to the recovery process, which provided the foundational protective element against relapse. Within this context, two major thematic factors emerged: personal factors and external factors. Personal factors came from within the individual and included such features as removing the obsession to use, self-realization, inner strength, and seeing the future. External factors were ex…

The oxytocin analogue carbetocin prevents emotional impairment and stress-induced reinstatement of opioid-seeking in morphine-abstinent mice.
The main challenge in treating opioid addicts is to maintain abstinence due to the affective consequences associated with withdrawal which may trigger relapse. Emerging evidence suggests a role of the neurohypophysial peptide oxytocin (OT) in the modulation of mood disorders as well as drug addiction. However, its involvement in the emotional consequences of drug abstinence remains unclear. We investigated the effect of 7-day opioid abstinence on the oxytocinergic system and assessed the effect of the OT analogue carbetocin (CBT) on the emotional consequences of opioid abstinence, as well as relapse. Male C57BL/6J mice were treated with a chronic escalating-dose morphine regimen (20-100 mg/kg/day, i.p.). Seven days withdrawal from this administration paradigm induced a decrease of hypothalamic OT levels and a concomitant increase of oxytocin receptor (OTR) binding in the lateral septum a…

Pharmacologically assisted treatment of opioid-dependent youth.
Opioid misuse, abuse, and dependence are global problems whose patterns vary across cultures. In the USA, the non-medical use of prescription opioids has become particularly serious because of its association with addiction and overdose death. Agonist and antagonist medications have been shown to be effective for opioid-dependent adults, and there is a growing body of data that they are also effective for youth. Here, we summarize evidence that detoxification alone results in high rates of treatment dropout and relapse but that the limited but growing data on the extended use of medication-assisted treatment for opioid-dependent youth have been positive. The implementation of medication-assisted treatment as a standard practice is feasible, easily integrated with counseling or psychotherapy, and has potential to greatly improve outcomes. Although concerns about safety and efficacy with y…

According to the World Health Organization, about 2 billion people drink alcohol. Excessive alcohol consumption can result in alcohol addiction, which is one of the most prevalent neuropsychiatric diseases afflicting our society today. Prevention and intervention of alcohol binging in adolescents and treatment of alcoholism are major unmet challenges affecting our health-care system and society alike. Our newly formed German SysMedAlcoholism consortium is using a new systems medicine approach and intends (1) to define individual neurobehavioral risk profiles in adolescents that are predictive of alcohol use disorders later in life and (2) to identify new pharmacological targets and molecules for the treatment of alcoholism. To achieve these goals, we will use omics-information from epigenomics, genetics transcriptomics, neurodynamics, global neurochemical connectomes and neuroimaging (IM…

Genetic deletion of the neurokinin 1 receptor (NK1R) has been shown to decrease the reinforcing properties of opioids, but it is unknown whether pharmacological NK1R blockade has the same effect. Here, we examined the effect of L822429, a rat-specific NK1R antagonist, on the reinforcing properties of heroin in rats on short (1 h: ShA) or long (12 h: LgA) access to intravenous heroin self-administration. ShA produces heroin self-administration rates that are stable over time, whereas LgA leads to an escalation of heroin intake thought to model important dependence-related aspects of addiction. L822429 reduced heroin self-administration and the motivation to consume heroin, measured using a progressive-ratio schedule, in both ShA and LgA rats. L822429 also decreased anxiety-like behavior in both groups, measured on the elevated plus maze, but did not affect mechanical hypersensitivity obse…

Premature ejaculation and other sexual dysfunctions in opiate dependent men receiving methadone substitution treatment.
Background: A significant number of men with opiate misuse have sexual problems. Premature ejaculation (PE) occurs predominantly on discontinuation of the opiate but seems to persist in some cases. The aims of this study were to determine the rates of PE and other sexual dysfunctions in patients maintained on methadone; to determine the time of onset of PE in relation to onset of opiate misuse; and to look at the patients' perception of the effect of heroin and methadone on PE.
Methods: Sixty five men attending a tertiary referral clinic for methadone maintenance treatment were assessed cross-sectionally using a semi-structured questionnaire, clinical interview, review of clinical records and the International Index of Erectile Function (IIEF).
Results: Thirty eight (58.5%) subjects reported a "lifetime" history of PE. Twenty (30.76%) of them reported "current" history of PE. Eleven (16.…

Identification of brain nuclei implicated in cocaine-primed reinstatement of conditioned place preference: a behaviour dissociable from sensitization.
Relapse prevention represents the primary therapeutic challenge in the treatment of drug addiction. As with humans, drug-seeking behaviour can be precipitated in laboratory animals by exposure to a small dose of the drug (prime). The aim of this study was to identify brain nuclei implicated in the cocaine-primed reinstatement of a conditioned place preference (CPP). Thus, a group of mice were conditioned to cocaine, had this place preference extinguished and were then tested for primed reinstatement of the original place preference. There was no correlation between the extent of drug-seeking upon reinstatement and the extent of behavioural sensitization, the extent of original CPP or the extinction profile of mice, suggesting a dissociation of these components of addictive behaviour with a drug-primed reinstatement. Expression of the protein product of the neuronal activity marker c-fos …

Cue-induced alcohol-seeking behaviour is reduced by disrupting the reconsolidation of alcohol-related memories.
Rationale: In humans, the retrieval of memories associated with an alcohol-related experience frequently evokes alcohol-seeking behaviour. The reconsolidation hypothesis states that a consolidated memory could again become labile and susceptible to disruption after memory retrieval.
Objectives: The aim of our study was to examine whether retrieval of alcohol-related memories undergoes a reconsolidation process.
Methods: For this purpose, male Wistar rats were trained to self-administer ethanol in the presence of specific conditioned stimuli. Thereafter, animals were left undisturbed in their home cages for the following 21 days. Memory retrieval was performed in a single 5-min exposure to all alcohol-associated stimuli.
