Introduction: Very Low Nicotine Content (VLNC) cigarettes might be useful as part of a tobacco control strategy, but relatively little is known about their acceptability as substitutes for regular cigarettes. We compared subjective effects and demand for regular cigarettes and Very Low Nicotine Content (VLNC) cigarettes, and estimated cross-price elasticity for VLNC cigarettes, using simulated demand tasks. Methods: 40 New Zealand smokers sampled a VLNC cigarette and completed Cigarette Purchase Tasks to indicate their demand for regular cigarettes and VLNC cigarettes at a range of prices, and a cross-price task indicating how many regular cigarettes and VLNC cigarettes they would purchase at 0...

OBJECTIVE: This study tests whether exposure to state antismoking media campaigns is associated with increased support for comprehensive bans on smoking indoors and cigarette advertising. METHODS: We combine commercially available data on market-level state-sponsored antismoking advertisements with three waves of the Current Population Survey's Tobacco Use Supplement to test the relationship between market-level volume of state antismoking advertising exposure and support for tobacco control policy between 2001 and 2002...

Increased obesity rates, an evolving food supply and the overconsumption of energy dense foods has led to an increase in research exploring addictive eating behaviours. This study aimed to investigate food addiction in a sample of Australian adults using the revised Yale Food Addiction Survey (YFAS) 2.0 tool and how it is associated with dietary intake, personality traits and mental health issues. Australian adults were invited to complete an online survey that collected information including: demographics, dietary intake, depression, anxiety, stress and personality dimensions including impulsivity, sensation seeking, hopelessness and anxiety sensitivity...

OBJECTIVE: The dominant theoretical perspective that guides treatment evaluations in addiction assumes linearity in the relationship between treatment and outcomes, viewing behaviour change as a 'before and after event'. In this study we aim to examine how the direction of the trajectory of the process from addiction to recovery is constructed in personal narratives of active and recovering users. DESIGN: 21 life stories from individuals at different stages of recovery and active use were collected and analysed following the principles of narrative analysis...

The neuropeptide, galanin, is widely expressed in the central and peripheral nervous systems and is involved in a range of different functions including nociception, neurogenesis, hormone release, reproduction, cognitive function and appetite. Given the overlap between galanin expression and reward circuitry in the brain, galanin has been targeted for alcohol use disorder (AUD) and opioid dependency. Furthermore, the galanin-3 receptor (GAL3) specifically regulates emotional states and plays a role in motivation, reward and drug-seeking behaviour...

Learning to associate cues or contexts with potential threats or rewards is adaptive and enhances survival. Both aversive and appetitive memories are therefore powerful drivers of behaviour, but the inappropriate expression of conditioned responding to fear- and drug-related stimuli can develop into anxiety-related and substance abuse disorders respectively. These disorders are associated with abnormally persistent emotional memories and inadequate treatment, often leading to symptom relapse. Studies show that cannabidiol, the main non-psychotomimetic phytocannabinoid found in Cannabis sativa, reduces anxiety via 5-HT1A and (indirect) cannabinoid receptor activation in paradigms assessing innate responses to threat...

The detrimental effects of drug abuse are apparently not limited to individuals but may also impact the vulnerability of their progenies to develop addictive behaviours. Epigenetic signatures, early life experience and environmental factors, converge to influence gene expression patterns in addiction phenotypes and consequently may serve as mediators of behavioural trait transmission between generations. The majority of studies investigating the role of epigenetics in addiction do not consider the influence of social interactions...

REVIEW
Douglas Carroll, Annie T Ginty, Anna C Whittaker, William R Lovallo, Susanne R de Rooij
Recent research shows that blunted cardiovascular and cortisol reactions to acute psychological stress are associated with adverse behavioural and health outcomes: depression, obesity, bulimia, and addictions. These outcomes may reflect suboptimal functioning of the brain's fronto-limbic systems that are needed to regulate motivated behaviour in the face of challenge. In support of this, brain imaging data demonstrate fronto-limbic hypoactivation during acute stress exposure. Those demonstrating blunted reactions also show impairments of motivation, including lower cognitive ability, more rapid cognitive decline, and poorer performance on motivation-dependent tests of lung function...

In Spain, there is a need to improve chronic hepatitis C care among people who inject drugs (PWID). Injecting drug use is an important risk behaviour for hepatitis C virus (HCV) infection. Review of 28 sources of the relevant published literature mapped the size of the addiction-HCV population in Spain. Experts in opioid use disorder (OUD) treatment in Spain completed a consensus to define the population size, HCV prevalence and access or barriers to hepatitis C treatment for PWID populations. In Spain, over 300 000 individuals have a lifetime history of injecting drugs...

Dopaminergic medications used in the treatment of patients with Parkinson's disease are associated with motor and non-motor behavioural side-effects, such as dyskinesias and impulse control disorders also known as behavioural addictions. Levodopa-induced dyskinesias occur in up to 80% of patients with Parkinson's after a few years of chronic treatment. Impulse control disorders, including gambling disorder, binge eating disorder, compulsive sexual behaviour, and compulsive shopping occur in about 17% of patients with Parkinson's disease on dopamine agonists...

Behavioural addictions concern behaviour which generate pleasure (shopping, gambling, sex, etc.). Pathological gambling is the most common behavioural addiction in elderly people. It can be severely harmful causing psychological, financial and family problems and increasing the risk of suicide. Gambling addiction is underestimated in the elderly. Psychological, social and family support is important whatever the age, with treatment aiming to improve the person's quality of life, help them regain control of their gambling or stop altogether...

Psychotropic medicines represent, after alcohol, the second class of substances most susceptible to abuse by elderly people. It can be particularly difficult for caregivers to understand such behaviour as these are prescription-only medicines. This misuse is partly a result of older people tending to trivialise and overrate pharmaceutical drugs, ignoring the potential of non-medicinal methods and psychotherapeutic treatments. The boundaries between prescribed use, overuse, self-medication, excessive use, dependency or addiction to prescription drugs are blurred in older people...

The representations we have of old age are sometimes far from reality. An addiction may be discovered by chance late on, delaying diagnosis and treatment. A desire to change can be encouraged through expression, listening and analysing current behaviour.

Defined as sexually explicit material that elicits erotic thoughts, feelings, and behaviours, internet pornography is a prevalent form of media that may facilitate problematic use and craving for engagement. Research suggests that superordinate cognitions and information processing, such as desire thinking and metacognition, are central to the activation and escalation of craving in addictive behaviours. The current study aimed to contribute to the literature by testing the proposed metacognitive model of desire thinking and craving in a sample of problematic pornography users, while revising the model by incorporating negative affect...

OBJECTIVE: The Yale Food Addiction Scale (YFAS) is the only questionnaire that assesses food addiction (FA) based on substance dependence criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, Text Revision. Following recent updating of addiction criteria, a new DSM-5 version (YFAS 2.0) has been developed. Our study tested the psychometric properties of the French YFAS 2.0 in a nonclinical population. METHOD: We assessed 330 nonclinical participants for FA (French YFAS 2...

BACKGROUND: Understanding why people repeatedly attend Emergency Departments (EDs) for alcohol-related reasons is an important prerequisite to identifying ways of reducing any unnecessary demands on hospital resources. We use Andersen's Behavioural Model of Health Services Use to explore factors that contributed to repeat ED attendances. METHODS: Qualitative interviews were conducted with 30 people who repeatedly attended EDs for alcohol-related reasons (≥10 attendances in the past 12 months)...

Following the recent changes to the diagnostic category for addictive disorders in DSM-5, it is urgent to clarify what constitutes behavioural addiction to have a clear direction for future research and classification. However, in the years following the release of DSM-5, an expanding body of research has increasingly classified engagement in a wide range of common behaviours and leisure activities as possible behavioural addiction. If this expansion does not end, both the relevance and the credibility of the field of addictive disorders might be questioned, which may prompt a dismissive appraisal of the new DSM-5 subcategory for behavioural addiction...

The concept of food addiction is increasingly used in the academic literature and popular media to explain some forms of overweight and obesity. However, there is limited evidence on how this term is understood by and impacts overweight and obese individuals. This qualitative study investigated the views of overweight and obese individuals on food addiction, and its likely impact upon stigma, treatment-seeking, and support for public policies to reduce overeating. Semi-structured interviews were conducted with 23 overweight and obese individuals (Mage = 38, MBMI = 33, 74% female) and analysed thematically...

OBJECTIVE: This study describes the impact of traumatic brain injury (TBI) and hazardous drinking on mental health and behavioural issues among Ontario adolescents. In particular, we assessed the incremental co-occurrence of hazardous drinking with a history of TBI, in comparison to experiencing just one of these conditions. METHODS: A cross-sectional subsample of 3130 Ontario adolescents attending grades 9-12, and aged 10-21 were surveyed in 2013 as a part of the Centre for Addiction and Mental Health's Ontario Student Drug Use and Health Survey...
