In the last few years, gamma hydroxybutyric acid (GHB) has been used increasingly as a party drug; this has led to a marked increase in the number of requests for professional help with the treatment of GHB addiction. Pharmaceutical GHB (sodium oxybate, the sodium-salt of GHB), registered for cataplexia in narcolepsy patients, is used off-label to treat the withdrawal symptoms associated with GHB addiction. Pharmaceutical GHB has a high sodium load. In this report we present the cases of two patients who developed symptomatic hypernatremia following treatment with pharmaceutical GHB and who thereafter needed intensive care for the severe withdrawal symptoms that they experienced...

BACKGROUND AND OBJECTIVES: Epidemiological studies consistently find that Asian populations report lower rates of alcohol use disorders (AUD) compared with other racial groups. These differences result from a variety of biological, genetic, and environmental influences, some of which are related to the metabolism of alcohol. We will review several studies of these metabolic factors, including several alcohol clamping studies conducted in our laboratory, that provide further insight into the role of the alcohol metabolizing genes and drinking behavior among Japanese drinkers...

: Midbrain dopamine neuron dysfunction contributes to various psychiatric and neurological diseases including drug addiction and Parkinson's disease. Because of its well-established dopaminotrophic effects, the therapeutic potential of glial cell line-derived neurotrophic factor (GDNF) has been extensively studied in various disorders with disturbed dopamine homeostasis. The outcomes from pre-clinical and clinical studies vary, however, highlighting a need for a better understanding of the physiological role of GDNF on striatal dopaminergic function...

BACKGROUND: Unemployed people with mental health problems often do not use mental health services and therefore do not benefit from available therapies. As unemployed individuals outside the healthcare system are a hard-to-reach group, barriers to and facilitators of mental health service use are poorly understood. The purpose of this study was to identify barriers to and facilitators of help-seeking and service use based on experiences of unemployed people with mental health problems...

Data suggest psychedelics such as psilocybin and lysergic acid diethylamide (LSD) may hold therapeutic potential in the treatment of addictions, including tobacco dependence. This retrospective cross-sectional anonymous online survey characterized 358 individuals (52 females) who reported having quit or reduced smoking after ingesting a psychedelic in a non-laboratory setting ⩾1 year ago. On average, participants smoked 14 cigarettes/day for 8 years, and had five previous quit attempts before their psychedelic experience...

Purpose Several lung cancer risk prediction models have been developed, but none to date have assessed the predictive ability of lung function in a population-based cohort. We sought to develop and internally validate a model incorporating lung function using data from the UK Biobank prospective cohort study. Methods This analysis included 502,321 participants without a previous diagnosis of lung cancer, predominantly between 40 and 70 years of age. We used flexible parametric survival models to estimate the 2-year probability of lung cancer, accounting for the competing risk of death...

Drug addiction implicates both reward learning and homeostatic regulation mechanisms of the brain. This has stimulated 2 partially successful theoretical perspectives on addiction. Many important aspects of addiction, however, remain to be explained within a single, unified framework that integrates the 2 mechanisms. Building upon a recently developed homeostatic reinforcement learning theory, the authors focus on a key transition stage of addiction that is well modeled in animals, escalation of drug use, and propose a computational theory of cocaine addiction where cocaine reinforces behavior due to its rapid homeostatic corrective effect, whereas its chronic use induces slow and long-lasting changes in homeostatic setpoint...

BACKGROUND: Although the efficacy and safety of smoking cessation interventions are well established, their efficacy and safety in patients with cardiovascular disease (CVD) remain unclear. The objective of this study was to evaluate the efficacy and safety of pharmacological and behavioral smoking cessation interventions in CVD patients via a meta-analysis of randomized controlled trials. METHODS AND RESULTS: EMBASE, PsycINFO, MEDLINE, PubMed, and the Cochrane Tobacco Addiction Specialized Register were searched for randomized controlled trials evaluating the efficacy of smoking cessation pharmacotherapies and behavioral therapies in CVD patients...

A disruption of the oxytocin system seems to affect a variety of brain functions including emotions, mood and social behavior possibly underlying severe social deficits and susceptibility for substance use and mental health disorders. Early life adversity, such as insecure attachment in childhood, has been suggested to influence oxytocin tone contributing to a condition of neurobiological vulnerability. Aim of the present study was to investigate oxytocin serum levels in abstinent heroin addicted patients, in comparison with healthy controls, and the possible correlation with co-occurring psychiatric symptoms, aggressiveness and perception of parental neglect...

Sharon E Murphy
Nicotine is the primary addictive agent in tobacco, and P450 2A6 (gene name: CYP2A6) is the primary catalyst of nicotine metabolism. It was proposed more than 20 years ago that individuals who metabolize nicotine poorly would smoke less, either fewer cigarettes per day or less intensely per cigarette, compared to smokers who metabolize nicotine more efficiently. These poor metabolizers would then be less likely to develop lung cancer due to their lower exposure to the many carcinogens delivered with nicotine in each puff of smoke...

REVIEW
Grzegorz Dobrzanski, Małgorzata Kossut
The DREADD (Designer Receptors Exclusively Activated by Designer Drugs) technique is a new chemogenetic approach allowing for selective and remote control of neural activity with a high degree of spatial resolution. Since its discovery in 2007 the DREADD technique was successfully employed into basic research, and together with the optogenetic method provided so far the best tool to influence the activity of the brain circuits and cell populations. The first aim of this review was to concisely describe the technique with regard to such issues like the history of its development, biochemistry as well as modes of the designer receptors delivery and expression...

Zebrafish have become a popular animal model for studying the development of alcohol addiction. Several behavioral paradigms for studying alcohol addiction have been developed for zebrafish, including conditioned place preference, alcohol-induced tolerance, and withdrawal. However, alcohol choice preference tasks have not been established in zebrafish as of yet. The ability of zebrafish to detect alcohol in their environment is required in alcohol choice or preference tasks. To our knowledge, it is currently unknown whether zebrafish are able to detect alcohol in their environment immediately following bath immersion...

Background and aims Internet Gaming Disorder is included in the Diagnostic and statistical manual of mental disorders (5(th) edition) as a disorder that merits further research. The diagnostic criteria are based on those for Substance Use Disorder and Gambling Disorder. Excessive gamblers and persons with Substance Use Disorder show attentional biases towards stimuli related to their addictions. We investigated whether excessive Internet gamers show a similar attentional bias, by using two established experimental paradigms...

Background The theory of work craving defines workaholism as a pathological work addiction which comprises: (a) obsessive-compulsive desire to work, (b) anticipation of self-worth compensatory incentives from working, (c) anticipation of reduction of negative emotions or withdrawal symptoms from working, and (d) neurotic perfectionism. Research has shown that workaholism is associated with adverse health outcomes. However, the antecedents of workaholism and the causal direction of the relationship with health have been largely neglected...
