The effect of perceived risk on the combined used of alcohol and marijuana: Results from daily surveys
. Gloria Yeomans-Maldonado, M. E. Patrick

Addictive Behaviors Reports (2015). Vol. 2 pp. 33-36

Abstract
Studies looking at the association between perceived risk and simultaneous use of alcohol and marijuana are scarce. The present study has three purposes: (1) to examine the association between alcohol and marijuana use at the daily level, (2) to document how this association varies by the perceived risk of using alcohol and marijuana simultaneously, (3) to test whether the association varies by college attendance. 89 young adults (Mean Age = 18.3 years, SD = 0.5) participated between October 2012 and May 2013. Participants completed a 30-min survey followed by 14 brief daily surveys in each of three waves. Alcohol use on a given day was associated with increased odds of marijuana use that day, especially among young adults with lower perceived risk. For college students, the association between alcohol and marijuana was weaker than for non-students. Alcohol and marijuana use were associated at a daily level, especially among young adults with lower perceived risk and those who were not attending college.

Heavy cannabis use and attentional avoidance of anxiety-related stimuli
T. Wilcockson, . N.E.M. Sanal

Addictive Behaviors Reports (2016). Vol. 3 pp. 38-42

Abstract
Cannabis is now the most widely used illicit substance in the world. Previous research demonstrates that cannabis use is associated with dysfunctional affect regulation and anxiety. Anxiety is characterised by attentional biases in the presence of emotional information. This novel study therefore examined the attentional bias of cannabis users when presented with anxiety-related stimuli. The aim was to establish whether cannabis users respond to anxiety-related stimuli differently to control participants. A dot-probe paradigm was utilised using undergraduate students. Trials contained anxiety-related stimuli and neutral control stimuli. Eye-tracking was used to measure attention for the stimuli. Results indicated that cannabis users demonstrated attentional-avoidance behaviour when presented with anxiety-related stimuli. The findings suggest a difference in processing of emotional information in relation to neutral information between groups. It would appear that cannabis users avoid anxiety provoking stimuli. Such behaviour could potentially have motivational properties that could lead to exacerbating anxiety disorder-type behaviour.

Addictive Behaviors Reports (2015).

Abstract
Smoking and gambling are two significant public health concerns. Little is known about the association of smoking and gambling in adolescents. The current study of high-school adolescents examined: (1) smoking behavior by problem-gambling severity and (2) health-related variables by problem-gambling severity and smoking status. Analyses utilized survey data from 1591 Connecticut high-school students. Adolescents were classified by problem-gambling severity (Low-Risk Gambling [LRG], At-Risk/Problem Gambling [ARPG]) and smoking status (current smoker, non-smoker). Analyses examined the smoking behavior of ARPG versus LRG adolescents as well as the smoking-by-problem-gambling-severity interactions for health and well-being measures (e.g., grades, substance use). Chi-square and logistic regression analyses were used, the latter controlled for gender, race/ethnicity, school grade, and family structure. More adolescents with ARPG than LRG reported regular smoking, heavy smoking, early smoking onset, no smoking quit attempts, and parental approval of smoking. ARPG and LRG adolescents who smoked were more likely to report poor grades, lifetime use of marijuana and other drugs, current heavy alcohol use, current caffeine use, depression, and aggressive behaviors and less likely to report participation in extracurricular activities. The association between not participating in extracurricular activities and smoking was statistically stronger in the LRG compared to the ARPG groups. Post-hoc analyses implicated a range of extracurricular activities including team sports, school clubs, and church activities. Smoking was associated with poorer health-related behaviors in both ARPG and LRG groups. Interventions with adolescents may benefit from targeting both smoking and gambling.

Online-specific fear of missing out and Internet-use expectancies contribute to symptoms of Internet-communication disorder
. Elisa Wegmann, . Ursula Oberst, . Benjamin Stodt, . Matthias Brand

Addictive Behaviors Reports (2017). Vol. 5 pp. 33-42

Abstract
Some of the most frequently used online applications are Facebook, WhatsApp, and Twitter. These applications allow individuals to communicate with other users, to share information or pictures, and to stay in contact with friends all over the world. However, a growing number of users suffer from negative consequences due to their excessive use of these applications, which can be referred to as Internet-communication disorder. The frequent use and easy access of these applications may also trigger the individuals fear of missing out on content when not accessing these applications. Using a sample of 270 participants, a structural equation model was analyzed to investigate the role of psychopathological symptoms and the fear of missing out on expectancies towards Internet-communication applications in the development of symptoms of an Internet-communication disorder. The results suggest that psychopathological symptoms predict higher fear of missing out on the individuals Internet-communication applications and higher expectancies to use these applications as a helpful tool to escape from negative feelings. These specific cognitions mediate the effect of psychopathological symptoms on Internet-communication disorder. Our results are in line with the theoretical model by Brand et al. (2016) as they show how Internet-related cognitive bias mediates the relationship between a persons core characteristics (e.g., psychopathological symptoms) and Internet-communication disorder. However, further studies should investigate the role of the fear of missing out as a specific predisposition, as well as specific cognition in the online context.

Smoke signals: The decline of brand identity predicts reduced smoking behaviour following the introduction of plain packaging
. Hugh Webb, B. M. Jones, . Kathleen McNeill, L. Lim, A. J. Frain, K. J. O'Brien, D. P. Skorich, . Peta Hoffmann, . Tegan Cruwys

Addictive Behaviors Reports (2017).

Abstract
This study tests a social identity based mechanism for the effectiveness of plain tobacco packaging legislation, introduced in Australia in December 2012, to reduce cigarette smoking. 178 Australian smokers rated their sense of identification with fellow smokers of their brand, positive brand stereotypes, quitting behaviours and intentions, and smoking intensity, both before and seven months after the policy change. Mediation analyses showed that smokers, especially those who initially identified strongly with their brand, experienced a significant decrease in their brand identity following the introduction of plain packaging and this was associated with lower smoking behaviours and increased intentions to quit. The findings provide the first quantitative evidence that brand identities may help maintain smoking behaviour, and suggest the role of social-psychological processes in the effectiveness of public health policy.

Ordinary people associate addiction with loss of free will
A. J. Vonasch, C. J. Clark, . Stephan Lau, K. D. Vohs, R. F. Baumeister

Addictive Behaviors Reports (2017).

Abstract
It is widely believed that addiction entails a loss of free will, even though this point is controversial among scholars. There is arguably a downside to this belief, in that addicts who believe they lack the free will to quit an addiction might therefore fail to quit an addiction. A correlational study tested the relationship between belief in free will and addiction. Follow-up studies tested steps of a potential mechanism: 1) people think drugs undermine free will 2) people believe addiction undermines free will more when doing so serves the self 3) disbelief in free will leads people to perceive various temptations as more addictive. People with lower belief in free will were more likely to have a history of addiction to alcohol and other drugs, and also less likely to have successfully quit alcohol. People believe that drugs undermine free will, and they use this belief to self-servingly attribute less free will to their bad actions than to good ones. Low belief in free will also increases perceptions that things are addictive. Addiction is widely seen as loss of free will. The belief can be used in self-serving ways that may undermine peoples efforts to quit.

Addictive Behaviors Reports (2016).

Abstract
Although American Indians/Alaska Natives (AI/ANs) have exhibited high rates of alcohol and drug use disorders, there is a paucity of substance use disorder treatment outcome research. In addition, there exists controversy about whether evidence-based treatments (EBTs) are culturally appropriate given that they were derived mainly by and for non-Hispanic White populations and do not explicitly include aspects of AI/AN culture and worldview. In this pilot study, we collaboratively culturally adapted two EBTs, Motivational Interviewing and Community Reinforcement Approach (MICRA), and evaluated substance use and psychological outcomes at 4- and 8-months post-baseline assessment. In preparation for a larger randomized clinical trial (RCT), eight tribal members (75% male) participated in this pilot treatment study. Measures included substance use, urine screens, self-efficacy, psychological distress, and hopelessness. All participants completed follow-up assessments at 4- and 8-months. Due to small sample size, effect sizes were calculated to evaluate outcomes pre- and post-treatment. Despite high rates of abstinence at baseline, percent days abstinent (PDA) increased at the 8-month time point for the most commonly used substances (alcohol, Hedgess g = 0.59, and marijuana, g = 0.60) and for all substances combined (excluding tobacco, g = 0.56). Improvements in psychological distress (g = − 0.66) and 5 of the 7 Addiction Severity Index domains (range of g = − 0.42 to − 0.98) also emerged. Results suggest that culturally adapted EBTs yield significant improvements in alcohol use, psychological distress, and legal problems among AI/ANs. Future research using RCT methodology is needed to examine efficacy and effectiveness.

The association between at-risk gambling and binge drinking in the general Swedish population
. Kristina Sundqvist, . Ingvar Rosendahl, . Peter Wennberg

Addictive Behaviors Reports (2015). Vol. 2 pp. 49-54

Abstract
While the association between problem gambling and alcohol use disorders has been studied previously, little is known about the association between risk gambling and risk drinking. This study aimed at examining the association between at-risk gambling and binge drinking in the general Swedish population and to test whether this association remained after controlling for demographic factors. The data was part of a larger ongoing survey in the general Swedish population. Respondents (N = 19 530) were recruited through random digit dialing and interviewed about their alcohol habits (binge drinking), at-risk gambling (the Lie/Bet questionnaire) and demographics (gender, age, education, residence size, marital status, labor market status, country of origin and smoking). There was an association between lifetime at-risk gambling and current (12 months) weekly binge drinking for both men (OR = 1.73, CI 95%: 1.27–2.35) and women (OR = 2.27, CI 95%: 1.05–4.90). After controlling for demographics this association no longer remained significant (OR = 1.38, CI 95%, .99–1.90 for men and OR = 1.99, CI 95%: .94–4.66 for women). Age and smoking had the largest impact on this association. At-risk gambling and binge drinking are associated behaviors. However, it seems as if this association may be confounded by demographic variables. We hypothesize that similarities in personality profiles and health aspects could account for an additional part of the association.

Culture and age influences upon gambling and problem gambling
. Mythily Subramaniam, . Edimansyah Abdin, . Shazana Shahwan, J. Vaingankar, . Louisa Picco, C. Browning, S. Thomas, S. Ann Chong

Addictive Behaviors Reports (2015). Vol. 1 pp. 57-63

Abstract
This study aimed to (i) examine the prevalence and types of gambling, (ii) establish prevalence of ‘pathological’ gambling, (iii) explore the correlates of gambling, and (iv) establish psychiatric and physical comorbidity in a sample of older adult gamblers (≥ 60 years) in contrast to younger gamblers in a representative population sample in Singapore. This paper reports the results of a secondary analysis of data from a representative community survey of 6616 participants, of which 2252 had engaged in gambling activities at least once in their lifetime. 48.9% of older adults reported lifetime gambling. Older gamblers were more likely to be males, married or widowed (vs. never married), with pre-primary, primary and secondary education (vs. university), economically inactive (vs. employed) and had personal annual income of SGD $19, 999 and below (vs. SGD $50, 000 and above). Older gamblers had significantly higher rates of betting on horses, playing numbers or betting on lotteries, and playing Mahjong. After adjusting for demographic variables in multiple logistic regression analyses, gamblers aged 60 years and older had significantly lower odds of having pathological gambling than those in the younger age group (OR = 0.4). Older gamblers had significantly higher odds of having diabetes (OR = 3.2), hypertension (OR = 4.9), and any comorbid chronic physical condition assessed in this study. For the majority of older adults, gambling remains a recreational activity that is entertaining and a way of socialization. However, one must remain cognizant of the possible risks for some to develop disordered gambling.

The relative contribution of metacognitions and attentional control to the severity of gambling in problem gamblers
M. Spada, . Adam Roarty

Addictive Behaviors Reports (2015). Vol. 1 pp. 7-11

Abstract
The present study explored the relationship between metacognitions, attentional control, and the severity of gambling in problem gamblers. One hundred and twenty six problem gamblers completed the Depression Anxiety Stress Scales 21, the Meta-Cognitions Questionnaire 30, the Attentional Control Scale, and the Problem Gambling Severity Index. Results revealed that negative affect, four out of five metacognitions factors (positive beliefs about worry, negative beliefs about thoughts concerning danger and uncontrollability, cognitive confidence and beliefs about the need to control thoughts), and all attentional control factors (focusing, shifting and flexible control of thought) were correlated, in the predicted directions, with the severity of gambling. The same metacognitions were also found to be correlated, in the predicted directions, with attention focusing, however only negative beliefs about thoughts concerning danger and uncontrollability and cognitive confidence were found to be correlated with attention shifting and flexible control of thought. A hierarchical regression analysis showed that beliefs about the need to control thoughts were the only predictor of the severity of gambling controlling for negative affect. Overall these findings support the hypotheses and are consistent with the metacognitive model of psychological dysfunction. The implications of these findings are discussed.

Abstract
The prevalence of ADHD among patients with substance use disorder (SUD) is substantial. This study addressed the following research questions: Are early developmental, temperamental and educational problems overrepresented among SUD patients with ADHD compared to SUD patients without ADHD? Do this comorbid group receive early help for their ADHD, and are there signs of self-medicating with illicit central stimulants? An international, multi-centre cross-sectional study was carried out involving seven European countries, with 1205 patients in treatment for SUD. The mean age was 40 years and 27% of the sample was female. All participants were interviewed with the Mini International Neuropsychiatric Interview Plus and the Conners' Adult ADHD Diagnostic Interview for DSM-IV. SUD patients with ADHD (n = 196, 16.3% of the total sample) had a significantly slower infant development than SUD patients without ADHD (n = 1, 009, 83.4%), had greater problems controlling their temperament, and had lower educational attainment. Only 24 (12%) of the current ADHD positive patients had been diagnosed and treated during childhood and/or adolescence. Finally, SUD patients with ADHD were more likely to have central stimulants or cannabis as their primary substance of abuse, whereas alcohol use was more likely to be the primary substance of abuse in SUD patients without ADHD. The results emphasize the importance of early identification of ADHD and targeted interventions in the health and school system, as well as in the addiction field.

Alcohol reduction in the first trimester is unrelated to smoking, patient or pregnancy characteristics

Addictive Behaviors Reports (2017).

Abstract
Studies show alcohol-preferring mice reduce their alcohol intake during pregnancy, this study questions if the same is true for humans. The current investigation compares womens pre-pregnancy and first trimester alcohol consumption, examines if women with problem drinking diminish their alcohol intake during pregnancy, and determines if prenatal alcohol reduction is associated with characteristics of pregnancy, patients or smoking. 126 participants in weeks 1–12 of pregnancy, recruited from Obstetric and Family Practices, completed a survey during their initial prenatal visit including two gender-specific AUDITs (Alcohol Use Disorders Identification Tests) querying current and pre-pregnancy alcohol use. AUDIT-C (AUDIT items 1–3) scores measuring pre-pregnancy and first trimester alcohol consumption were compared, analyzed and tested using general linear model repeated. A p ≤ 0.05 was accepted as significant. Most participants were multiparous, Caucasian high school graduates experiencing nausea and vomiting. Pre-pregnancy alcohol use was significantly (p = 0.019, Fishers exact) higher among women seeing obstetricians. Pre-pregnancy AUDIT-C scores (m (mean) = 2.22, sd (standard deviation) = 2.19) were significantly higher (p < 0.001) than first trimester scores (m = 0.143, sd = 0.532). Among 49 with pre-pregnancy AUDIT-C scores ≥ 3, 45/49 (92%) reduced their alcohol use to zero during the first trimester. Age, race, education, marital status, parity, nausea and vomiting, gestational age and smoking were non-factors in score reduction. Women reported reducing their alcohol consumption during pregnancy, including those screening positive for pre-pregnancy problem drinking. First trimester alcohol reduction cannot be accounted for by smoking, patient or pregnancy characteristics, public health initiatives, psychological factors and hormonal mechanisms may be implicated.

Addictive Behaviors Reports (2016).

Abstract
Energy drinks are popular beverages that can have adverse long-term health effects when consumed by children and adolescents. This study sought to determine if the age of first energy drink use in a U.S. military population is predictive of the maximum number of energy drinks consumed during a single day and/or single occasion (operationally defined as a couple of hours, e.g., a night out, during studying or sport session). Student U.S. naval aviator and naval flight officers who reported past-year use of energy drinks (N = 239) were surveyed to determine various measures of energy drink consumption. Age of first consumption was predictive of the maximum number of energy drinks consumed during a single occasion within the past year. Within this sample, the age range between 13 and 16 years appeared to be a critical period with results indicating that people who began consuming energy drinks during this period were 4.88 times more likely to consume high quantities (four or more) of energy drinks during a single occasion when compared to those who started consuming energy drinks between the ages of 20–23. Likewise, persons who began to consume energy drinks between the ages of 13–16 are 2.48 times more likely to consume high quantities of energy drinks during a single occasion than those who started between the ages of 17–19. There was no difference between 17 and 19 year olds and 20–23 year olds. Age of first use was not correlated to daily average intake or daily maximal intake of energy drinks. A lower age of first energy drink use suggests higher risk of single-occasion heavy episodic consumption in this military population. Researchers should further explore the relationship of early onset energy drink consumption and potential future health risks.

Individual differences in implicit learning abilities and impulsive behavior in the context of Internet addiction and Internet Gaming Disorder under the consideration of gender
. Rayna Sariyska, B. Lachmann, . Sebastian Markett, . Martin Reuter, . Christian Montag

Addictive Behaviors Reports (2017). Vol. 5 pp. 19-28

Abstract
In three consecutive studies, we aimed to investigate the relationship between problematic Internet use (PIU), Internet Gaming Disorder (IGD) and implicit learning abilities, and impulsivity/risk-taking among online video gamers and control participants. In study 1, male visitors, recruited at the “Gamescom” in Cologne (2013), filled in a short version of the Internet Addiction Test (s-IAT), the Online Gaming Addiction Scale (OGAS), and completed an experimental task to assess implicit learning abilities. In study 2, a group of WoW gamers and control participants completed the same set up, in order to replicate the results of study 1. Study 3 used a modified version of the experiment to measure impulsivity/risk-taking in a group of healthy participants. In study 1, results revealed a significant negative correlation between the s-IAT score and the measure of implicit learning among male Gamescom participants. In study 2, the s-IAT and WoW addiction scores were negatively correlated with implicit learning only in male WoW players, which mirrors the results from study 1. In study 3, the OGAS score was positively correlated with the experimental measure of impulsivity/risk-taking. In the current research project, deficient implicit learning was linked to PIU only in male participants with (a tendency towards) IGD. These findings might help to disentangle some opposing results on this relationship, when considering the gender of participants. Furthermore, higher risk-taking tendencies were associated with IGD among healthy participants, thus, suggesting the potential of risk taking as a predictor of IGD in a non-gamer population.

Prospective recovery of cannabis use in a psychotic population: A qualitative analysis
. Shane Rebgetz, . Leanne Hides, D. J. Kavanagh, . Anand Choudhary

Addictive Behaviors Reports (2016). Vol. 4 pp. 31-36

Abstract
There is growing evidence for natural recovery from cannabis use by people with psychosis, but mechanisms underpinning it need further exploration. This study prospectively explored this issue. Twenty-two people with psychosis and cannabis misuse were recruited: 19 provided data for at least one follow-up assessment, and 13 of these (68%) reduced or ceased using cannabis. A semi-structured interview with the latter group explored reasons for initiating the attempt, strategies they employed, and context/s where any relapse occurred. Interpretative phenomenological analysis was used to identify themes. Participants who reduced or ceased cannabis use had fewer negative symptoms at Baseline, and were more likely to only use cannabis. Major reasons for starting an attempt were worsening mental health, relationship and lifestyle difficulties. Effective strategies fell into psychological, relationship, lifestyle and medication themes. Only three participants reported a relapse: triggers involved substance-using peers, relationship difficulties, and problems with negative emotions including ones from past trauma. An encouragingly high rate of maintained reductions in cannabis use was seen. Increased awareness of the benefits across multiple life domains from addressing cannabis use may be critical to the initiation and maintenance of attempts, both to maximise motivation, and avoid over-dependence on improvements in any single domain. Negative symptoms, multiple substance use, dysphoria and pressure from substance-using peers clearly offer additional challenges for control.

Systematic analysis of changes in cannabis use among participants in control conditions of randomised controlled trials
. Shane Rebgetz, . Leanne Hides, D. Kavanagh

Addictive Behaviors Reports (2015). Vol. 1 pp. 76-80

Abstract
Cannabis remains the most used illegal substance across the globe, and negative outcomes and disorders are common. A spotlight therefore falls on reductions in cannabis use in people with cannabis use disorder. Current estimates of unassisted cessation or reduction in cannabis use rely on community surveys, and few studies focus on individuals with disorder. A key interest of services and researchers is to estimate effect size of reductions in consumption among treatment seekers who do not obtain treatment. Effects within waiting list or information-only control conditions of randomised controlled trials offer an opportunity to study this question. This paper examines the extent of reductions in days of cannabis use in the control groups of randomised controlled trials on treatment of cannabis use disorders. A systematic literature search was performed to identify trials that reported days of cannabis use in the previous 30 (or equivalent). Since all but one of the eight identified studies had delayed treatment controls, results could only be summarised across 2–4 months. Average weighted days of use in the previous 30 days fell from 24.5 to 19.9, and a meta-analysis using a random effects model showed an average reduction of 0.442 SD. However, every study had at least one significant methodological issue. While further high-quality data is needed to confirm the observed effects, these results provide a baseline from which researchers and practitioners can estimate the extent of change required to detect effects of cannabis treatments in services or treatment trials.

The impact of Internet-based specific activities on the perceptions of Internet addiction, quality of life, and excessive usage: A cross-sectional study
H. Pontes, . Attila Szabo, M. D. Griffiths

Addictive Behaviors Reports (2015).

Abstract
Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than ‘generalized’ Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (Mage = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

Confirmatory factor analysis of the Spanish version of the Gamblers' Beliefs Questionnaire in a sample of Argentinean gamblers
. Angelina Pilatti, . Marcos Cupani, F. Tuzinkievich, . Walter Winfree

Addictive Behaviors Reports (2016). Vol. 4 pp. 44-50

Abstract
Introduction: Cognitive distortions are related to gambling frequency and gambling severity. Having a culturally sensitive measure to assess cognitive distortions will facilitate the early detection of people who might be at risk of developing problematic gambling behaviors. The Gamblers' Beliefs Questionnaire was translated into Spanish (GBQ-S) but no previous study explored the structure of the GBQ-S in a non-US sample with different levels of gambling involvement. Aim: The present study examined the factor structure of the GBQ-S in a community sample of gamblers from Argentina. It also analyzed the association between cognitive distortions and type of gambling activity and frequency of gambling behaviors and the predictive utility of the GBQ-S on gambling severity. Participants: 508 youth and adults completed the GBQ-S. Results: The CFA showed an overall acceptable fit to the data confirming the proposed two-factor model. Scores of the two GBQ sub-scales were positively and significantly correlated with scores on gambling severity. Cognitive distortions have a significant effect on gambling severity after controlling for frequency of engagement in gambling activities. Luck and perseverance, but not illusion of control, was positively related to gambling severity. Discussion: scores measured by the GBQ-S exhibit adequate psychometric properties for the accurate assessment of cognitive distortions across adults and youth from the general community of Argentina.

People Control Their Addictions : No matter how much the “chronic” brain disease model of addiction indicates otherwise, we know that people can quit addictions – with special reference to harm reduction and mindfulness
S. Peele

Addictive Behaviors Reports (2016).

Abstract
The world, led by the United States, is hell bent on establishing the absence of choice in addiction, as expressed by the defining statement that addiction is a “chronic relapsing brain disease” (my emphasis). The figure most associated with this model, the director of the American National Institute on Drug Abuse, Nora Volkow, claims that addiction vitiates free will through its effects on the brain. In reality, while by no means a simple task, people regularly quit their substance addictions, often by moderating their consumption, usually through mindfulness-mediated processes (Peele, 2007). Ironically, the brain disease models ascendance in the U.S. corresponds with epidemic rises in opiate addiction, both painkillers (Brady et al., 2016) and heroin (CDC, n.d.), as well as heroin, painkiller, and tranquilizer poisoning deaths (Rudd et al., 2016). More to the point, the conceptual and treatment goal of eliminating choice in addiction and recovery is not only futile, but iatrogenic. Indeed, the National Institute on Alcohol Abuse and Alcoholisms epidemiological surveys, while finding natural recovery for both drug and alcohol disorders to be typical, has found a decline in natural recovery rates (Dawson et al., 2005) and a sharp increase in AUDs (Grant et al., 2015).
