BACKGROUND: Mandating a reduction in the nicotine content of cigarettes to a minimally addictive level could dramatically reduce smoking rates in the US. However, little is known about the effects of reduced nicotine content cigarettes in adolescents. METHODS: Following overnight abstinence, adolescent daily smokers (ages 15-19, n = 50) reported on their craving, withdrawal, and positive and negative affect pre- and post- ad lib smoking of one cigarette containing varying nicotine content (15...

The present study investigated the effect of two craving reduction techniques, namely, cognitive defusion and guided imagery, on naturalistic food cravings. These techniques targeted the intrusion and elaboration stages of the craving process, respectively (Kavanagh, Andrade, & May, 2005). Participants underwent a seven-day baseline period followed by a seven-day intervention period, during which they recorded their food cravings as they occurred using online diaries accessed via smartphone. In the intervention period, participants were randomly assigned to one of cognitive defusion, guided imagery or control conditions...

Research reports show increased prevalence of habitual khat chewing among various parts of the community in Ethiopia. Some users experience problems controlling their use; withdrawal symptoms may be adding to difficulties with reducing or ceasing use. We aimed to describe the nature and the time course of any withdrawal syndrome in relation to the cessation of khat use over the first 2 weeks of a quit attempt. Fifty-nine participants between the ages of 18 and 35 and who have already chewed ≥1 bundle of khat in their life with a chewing frequency of ≥3 days per week were recruited from Adama Science and Technology University campus...

Cue reactivity has great potential to advance our understanding of posttraumatic stress disorder (PTSD), substance use disorder (SUD), and PTSD/SUD comorbidity. The present investigation examined distress tolerance (DT) with regard to trauma and substance cue reactivity. Participants included 58 low-income, inner-city adults (49.1% women; Mage = 45.73, SD = 10.00) with substance dependence and at least 4 symptoms of PTSD. A script-driven cue reactivity paradigm was utilized. Four DT measures were administered, including the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath-Holding Task (BH), and Paced Auditory Serial Addition Task (PASAT)...

OBJECTIVES: While exercise significantly reduces craving for cigarettes, the effect of exercise on self-initiation of quit attempts is less known. Therefore, this randomized pilot study explored the effect of starting an exercise program on self-initiated quit attempts, and also the feasibility and acceptability of a novel exercise intervention, high-intensity interval training (HIIT), as compared with a more traditional continuous aerobic (CA) exercise intervention. METHODS: Participants smoked (≥5 cigarettes/d), were aged 18 to 40 years, and wanted to increase their exercise...

REVIEW
MacKenzie R Peltier, Mehmet Sofuoglu
Substance use disorders (SUDs) remain problematic as many individuals are untreated or do not benefit from the currently available interventions. Thus, there is an urgent need to develop novel pharmacological interventions to treat SUDs. Evidence suggests that the female sex hormone, progesterone, attenuates the craving for and the euphoric effects of drugs of abuse. Research to date has demonstrated that progesterone may modulate responses to drugs of abuse and may have utility as a novel treatment for SUDs...

Mobile phone addiction has attracted much attention recently and is showing similarity to other substance use disorders. Because no studies on mobile phone addiction had yet been conducted in Spain, we developed and validated a questionnaire (Cuestionario de Abuso del Teléfono Móvil, ATeMo) to measure mobile phone abuse among young adults in Spanish. The ATeMo questionnaire was designed based on relevant DSM-5 diagnostic criteria and included craving as a diagnostic symptom. Using stratified sampling, the ATeMo questionnaire was administered to 856 students (mean age 21, 62% women)...

Crosstalk between G-protein signaling and glutamatergic transmission within the brain reward circuits is critical for long-term emotional effects (depression and anxiety), cravings, and negative withdrawal symptoms associated with opioid addiction. A previous study showed that Regulator of G-protein signaling 4 (RGS4) may be implicated in opiate action in the nucleus accumbens (NAc). However, the mechanism of the NAc-specific RGS4 actions that induce the behavioral responses to opiates remains largely unknown...

OBJECTIVES: Opioid-treated chronic pain patients may be at risk for prescription opioid misuse due to heightened opioid craving coupled with deficits in attention to naturally rewarding, positive stimuli. Conversely, dispositional mindfulness, which is associated with reduced craving and increased responsiveness to natural rewards, may serve as a protective factor and buffer opioid misuse risk. The current investigation aimed to examine the association between mindfulness and opioid misuse, and to test opioid craving and attention to positive information as mediators of this relationship...

BACKGROUND: Varenicline is an FDA approved medication for the treatment of nicotine dependence. While the efficacy and safety of this medication have been demonstrated, success rates remain low, and efforts to understand mechanisms of efficacy are in progress. A behavioral economics framework is one unique way to examine how demand for a drug changes under different circumstances. Therefore, the current randomized placebo-controlled, cross-over study aimed to examine effects of varenicline on subjective cigarette craving and objective demand for cigarettes measured by a hypothetical behavioral economic task as well as associations between subjective craving and objective demand...

Regulation of food cravings is thought to be critical for modulating eating behavior, yet we do not fully understand the mechanisms by which cognitive control operates in the eating context. The current study combined rTMS and EEG paradigms to examine the causal role of the left dorsolateral prefrontal cortex (dlPFC) in modulating visceral and behavioral responses to high calorie foods, and the mediational mechanisms underlying this relation. 28 right-handed female participants received both active and sham continuous theta burst stimulation (cTBS; a rTMS variant used to decrease cortical activity) targeting the left dlPFC in a counterbalanced order...

Alcohol use disorder generates devastating social, medical and economic burdens, making it a major global health issue. The persistent nature of memories associated with intoxication experiences often induces cravings and triggers relapse in recovering individuals. Despite recent advances, the neural and molecular mechanisms underlying these memories are complex and not well understood. This makes finding effective pharmacological targets challenging. The investigation of persistent alcohol-associated memories in the fruit fly, Drosophila melanogaster , presents a unique opportunity to gain a comprehensive understanding of the memories for ethanol reward at the level of genes, molecules, neurons and circuits...

Depression is one of the most prevalent psychiatric disorders among opioid-dependent individuals. Clinical trials testing selective serotonin reuptake inhibitors among depressed patients on methadone maintenance therapy (MMT) failed to show efficacy, whereas those on tricyclic antidepressants produced mixed results with potential for cardiotoxicity. Desvenlafaxine (DESV) is a SNRI with minimal cardiotoxicity and drug interactions. This study sought to assess feasibility and tolerability of using DESV in depressed patients on MMT...

For nurses, shift work is a necessity, required to provide 24-h continuous care for patients. Research posits that fatigue amongst shift-working nurses is associated with inadequate and poorly timed sleep and also strongly influenced by the timing, quality and quantity of food consumed. The aim of this investigation was to examine differences and similarities in the food choices and eating patterns of nurses exposed to different lengths of time in shift work, as a means of understanding how nurses can adapt their eating patterns to better manage fatigue and sleep loss...

Prevalence of cannabis use is increasing, but many regular users do not develop cannabis use disorder (CUD); thus, CUD risk identification among current users is vital for targeted intervention development. Existing data suggest that high distress intolerance (DI), an individual difference reflective of the ability to tolerate negative affect, may be linked to CUD, but no studies have tested possible neurophysiological mechanisms. Increased motivated attentional processing of cannabis and negative emotional stimuli as indexed by neurophysiology [i...

BACKGROUND: Benzodiazepines are the conventional mainstay to manage alcohol withdrawal; however, patients are subsequently at increased risk for poor sleep, cravings, and return to drinking. Research on alternative pharmacologic agents to facilitate safe alcohol withdrawal is scant. Gabapentin is one medication shown in small studies to reduce the need for benzodiazepines in the setting of alcohol withdrawal. The continuation of gabapentin after alcohol withdrawal appears to be safe during early sobriety and may aid in reducing alcohol-related cravings or returning to alcohol consumption...

Non-invasive electrical stimulation of the brain has recently been extensively investigated to regulate food craving. However, the existing literature is controversial and there are some important questions which need to be addressed about clinical and technical factors contributing to efficacy of this method. A systematic search was performed in reliable scientific databases, and 15 eligible studies were identified. The pooled standardized mean differences for the effects of transcranial direct current stimulation (tDCS) on Visual Analogue Scale, energy intake and food craving questionnaire were -0...

BACKGROUND: Perceived stress and psychological distress are associated with more cigarette craving and withdrawal, higher nicotine dependence, and less success during quit attempts. Low income smokers have disproportionately higher rates of smoking and may be particularly vulnerable to the effects of stress on smoking dependence. The aim of the current study was to assess if lower income smokers have a stronger association between stress and nicotine dependence than higher income smokers...

Rodent studies indicate that ghrelin receptor blockade reduces alcohol consumption. However, no ghrelin receptor blockers have been administered to heavy alcohol drinking individuals. Therefore, we evaluated the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD) and behavioral effects of a novel ghrelin receptor inverse agonist, PF-5190457, when co-administered with alcohol. We tested the effects of PF-5190457 combined with alcohol on locomotor activity, loss-of-righting reflex (a measure of alcohol sedative actions), and on blood PF-5190457 concentrations in rats...
