BACKGROUND: Few effective treatment options exist for cannabis-using youth. This pilot study aimed to test Approach-Avoidance Training to reduce cannabis use with non-treatment-seeking adolescents. METHODS: Eighty cannabis-using non-treatment-seeking adolescents (average age 19) were recruited from San Diego, California and Charleston, South Carolina, and randomized to complete either six sessions of Cannabis Approach-Avoidance Task Training (CAAT-training) designed to reduce automatic approach biases for cannabis cues or CAAT-sham training...

BACKGROUND: Mindfulness-based relapse prevention (MBRP) is a method that combines cognitive behavioral relapse prevention with mindfulness practice. Research shows that MBRP can effectively reduce negative emotions and craving in people with substance use disorders (SUDs). An important part of MBRP is to practice mindfulness meditation to cope with high-risk situations for relapse, such as stimuli and situations associated with drug taking. Virtual reality cue exposure (VRCE) may be a complementary approach to MBRP as it allows for controlled and graded presentations of various high-risk situations with distal and proximal drug cues...

Sex differences in methamphetamine (MA) abuse and consequences of MA have been reported with females showing an increased addiction phenotype and withdrawal symptoms. One mechanism through which these effects might occur is via sex-specific alterations in the hypothalamic-pituitary-adrenal (HPA) axis and its associated brain regions. In this study, mice were administered MA (5 mg/kg) or saline for 10 consecutive days. During early withdrawal, anxiety-like behaviors were assessed in the open field, light/dark box, and elevated plus maze...

Drugs of abuse mediate adaptive mechanisms leading to alterations in the synaptic plasticity that has been shown to underlie addictive behaviors. Glial cells play a critical role in modulation of synaptic strength and are potentially involved in drug addiction. Chronic administration of morphine has been shown to increase glial cell activation; therefore, it is possible that altered neuroplasticity induced by drugs of abuse is in part mediated by the activity of glial cells. We investigated the effect of hippocampal glial inhibition on synaptic plasticity in morphine treated rats...

INTRODUCTION: Little is known about perception of physical pain in schizophrenia (SZ). Some studies have suggested that patients with SZ may have an increased pain threshold, while others have suggested that patients with SZ may suffer from undetected and untreated high physical pain levels. The objectives of this study were (i) to investigate the prevalence of self-reported physical pain in stabilized SZ subjects, and (ii) to determine whether physical pain was associated with psychiatric characteristics and somatic comorbidities (iii) to determine whether antidepressants and benzodiazepine administration were associated with lower self-reported pain...

Ionotropic glutamate receptors (AMPA, NMDA, and kainate receptors) play a central role in excitatory glutamatergic signaling throughout the brain. As a result, functional changes, especially long-lasting forms of plasticity, have the potential to profoundly alter neuronal function and the expression of adaptive and pathological behaviors. Thus, alcohol-related adaptations in ionotropic glutamate receptors are of great interest, since they could promote excessive alcohol consumption, even after long-term abstinence...

OBJECTIVES: The nucleus accumbens (NAc) is known to regulate the motivation and underlie addictive behaviors, and the anterior limb of the internal capsule (ALIC) is involved in several psychiatric disorders. Our study aimed to explore the functions of NAc and ALIC electrophysiologically. METHODS: The local field potentials (LFPs) of the NAc and ALIC were recorded from 7 heroin addicts treated with deep brain stimulation. Correlation analysis was made between LFP powers in various frequency bands and the subjects' neuropsychological test scores; coherence was calculated for the LFPs in NAc and ALIC...

BACKGROUND: Initial administration of ≥60% nitrous oxide (N2O) to rats evokes hypothermia, but after repeated administrations the gas instead evokes hyperthermia. This sign reversal is driven mainly by increased heat production. To determine whether rats will behaviorally oppose or assist the development of hyperthermia, we previously performed thermal gradient testing. Inhalation of N2O at ≥60% causes rats to select cooler ambient temperatures both during initial administrations and during subsequent administrations in which the hyperthermic state exists...

Interventions for drug abuse and other maladaptive habitual behaviors may yield temporary success but are often fragile and relapse is common. This implies that current interventions do not erase or substantially modify the representations that support the underlying addictive behavior-that is, they do not cause true unlearning. One example of an intervention that fails to induce true unlearning comes from Crossley, Ashby, and Maddox (2013, Journal of Experimental Psychology: General), who reported that a sudden shift to random feedback did not cause unlearning of category knowledge obtained through procedural systems, and they also reported results suggesting that this failure is because random feedback is noncontingent on behavior...

In light of expanding legalization of cannabis and swelling debate about the potential risks, particularly for younger users, understanding acute cannabis effects among adolescents and emerging adults is more important than ever. Contemporary models of addiction development identify subjective drug responses as central to the developmental unfolding of drug use disorders. Despite this, surprisingly little is known about cannabis's acute subjective effects in human youths. This research utilized ecological momentary assessment (EMA) in the natural environment to identify the typical situational context of cannabis use among 85 frequent cannabis users, ages 15-24 years (M = 19...

The threat imposed by the use of psychoactive, illicit drugs on human health and the cost of rehabilitation of the affected individuals is nothing less than billions of dollars per year. Of the psychoactive substance abuse drugs are amphetamine and its analogues like methamphetamine. This Viewpoint intends to draw the attention of readers toward the neurological basis of "falling a prey" to methamphetamine. Attention has been paid toward a rapid desensitizing attribute that develops shortly after the repetitive use of drugs belonging to sympathomimetic agents of this group...

Opioid misuse, including the use of heroin and the overprescribing, misuse, and diversion of opioid pain medications, has reached epidemic proportions in the United States. As a result, there has been a dramatic increase in opioid use disorder and associated overdoses and deaths. Addiction is a chronic brain disease with a genetic component that affects motivation, inhibition, and cognition. Patient characteristics associated with successful buprenorphine maintenance treatment include stable or controlled medical or psychiatric comorbidities and a safe, substance-free environment...

Research exploring the relationship between addictions and experiences of bullying suggests that problem behaviors may generally be associated with an increased risk of victimization. The aim of the present study was to examine the role of psychoactive substance use, excessive Internet use, and social support in both traditional offline bullying and online "cyberbullying" victimization in a nationally representative sample of adolescents ( N  = 6237; 51% male; M age  = 16.62 years, SD = 0.95)...

Addictive diseases, including addiction to alcohol pose massive public health costs. Addiction is a chronic relapsing disease, caused by both the direct effects induced by drugs and persistent neuroadaptations at several (molecular, cellular and behavioral) levels. These drug-type specific neuro-adaptations are brought on largely by the reinforcing effects of drugs on the central nervous system and environment, including stress. Results from animal experiments have demonstrated important interactions between alcohol and the stress responsive systems...

The Ottawa Self-Injury Inventory (OSI) is a comprehensive self-report measure of non-suicidal self-injury (NSSI). In an effort to build on past research and further validate the OSI, this study presents a confirmatory factor analysis of the OSI's subscales measuring the functions and addictive features of NSSI using a university sample. Participants were 316 university students aged 17-25 years (84.8% female) who had engaged in NSSI at least once in their lifetime. Consistent with past research, results confirmed the four-factor structure of the Functions items (Internal Emotion Regulation, Social Influence, External Emotion Regulation, Sensation Seeking), as well as the single-factor structure of Addictive Features items...
