Abstract
Objective: This study assessed the initial acceptability of SafeUse, a game-based opioid misuse prevention intervention for delivery via smartphone among adolescents. Evidence-based educational and refusal skills training materials were adapted, and game design elements were applied to clinically and scientifically informed scenarios in which opioids are typically introduced to adolescents using standard product development methods to create the SafeUse prototype. Materials and Methods: In a mixed-methods study, 14 adolescents were assessed on their knowledge and perceptions of opioids before and following 5-7 days of access to SafeUse. Participants provided feedback in focus groups on the acceptability, relevance, and understandability of SafeUse and made suggestions for its improvement. Feedback was coded and summarized as to playability, acceptability, appropriateness, content development, and knowledge transfer. Pre- and post-access quantitative data were analyzed using Wilcoxon matched pairs signed-rank tests. Results: Overall, participants liked SafeUse, its characters, graphics, and approach, finding it more appealing than lectures/reading materials and appropriate for school settings. They moderately to extremely "liked the game," "would like to play more game modules," "liked playing through the decisions," thought the game was realistic/relevant and fun, and they learned new information about opioids. Participants reported increased confidence to refuse opioids and decreased likelihood of accepting opioids from someone they know. Knowledge about opioids increased (P < 0.006), and adolescent perception that prescription drugs are safer than illegal drugs decreased (P < 0.003) after playing SafeUse. Conclusion: Findings suggest that SafeUse is acceptable and likely educational to adolescents and worthy of further development and research.

Abstract
OBJECTIVE The misuse of prescription stimulants among students has been identified as a public health problem. To date, most research has focused on individual-level determinants of stimulant misuse, making research on the socio-cultural context of students' misuse a priority. This study aims to test the applicability of the Theory of Triadic Influence, capturing three influence streams (personal, social and cultural) and three causational levels (ultimate, distal and proximal). METHOD A questionnaire on stimulant misuse was distributed among all bachelor's and master's students from the five Flemish medical faculties. In total, 3159 students participated (48.99% response rate). Data were analyzed using structural equation modeling. RESULTS Multiple personal (i.e., fear of failure, procrastination, self-perceived ADHD, sensation-seeking, academic stress, controllability), social (i.e., living situation, peer endorsement, social norm) and cultural (i.e., competitive study-environment, financial worries, positive and negative expectancies, attitude) factors were identified as risk factors of misuse intention. The strongest ultimate to distal pathway was found between self-perceived ADHD and positive expectancies, meaning that students who believed they have ADHD, although not diagnosed, were more likely to have positive expectancies about stimulants. Moreover, the strongest distal to proximal pathways were found between expectancies and attitudes toward stimulant misuse (i.e., more positive and fewer negative expectancies were associated with more favorable attitudes). Finally, attitudes were most strongly related to misuse intention. CONCLUSIONS The current study shows that the TTI is an important framework to understand the risk factors of stimulant misuse among medical students. This study offers a strong basis for prevention initiatives.

Abstract
Background: Nonmedical use of prescription drugs (NMPUD) has become a critical public health concern. Chinese literature has paid growing attention to NMUPD, but scarce research has focused on females who are sex workers (FSWs), who have a high risk of substance use. The current study aimed to examine NMUPD and its biopsychosocial correlates in Chinese FSWs. Methods: A total of 410 FSWs (mean age = 33.58 years) from Guangxi, China, completed an anonymous, self-administered survey evaluating NMUPD, somatic symptoms, and psychosocial distress. Results: Overall, 46.6% of FSWs reported lifetime NMUPD and 17.6% reported past-3-month NMUPD. The most commonly reported medications that were used nonmedically were analgesics (46.3%, lifetime; 17.6%, past 3 months). A majority of FSWs (69.1%) reported "relieving pain" as the motive of their NMUPD. FSWs reporting NMUPD were more likely to be younger, be unmarried, have higher income, and work in multiple venues/high-paying venues. Somatic symptoms and psychosocial distress were associated with NMUPD in Chinese FSWs. Conclusions: NMUPD was prevalent in Chinese FSWs and was associated with biopsychosocial factors. Critical attention should be paid to NMUPD in FSWs. Future NMUPD prevention intervention among FSWs may benefit from attending to biopsychosocial factors.

Abstract
BACKGROUND Prescription opioid misuse (POM) has become a critical public health issue in the United States (US), with veteran and military population being especially vulnerable to POM. However, limited behavioral interventions have been developed for veterans and military to reduce POM risk due to the lack of an adequate understanding of POM andrelated factors among veterans and military. The current study aims to review and synthesize empirical findings regarding POM and its correlates among US veterans and military. METHODS We conducted a systematic review of 17 empirical studies (16 quantitative studies and one qualitative study) from 1980 to 2019 that reported POM statistics (e.g., prevalence) and examined correlates of POM in veterans and military. RESULTS The prevalence of POM in veterans and military ranged from 6.9%-77.9% varying by study samples, individual POM behaviors, and recalled time periods. Several factors were identified to be associated with POM in veterans and military. These factors included socio-demographic factors (age, race/ethnicity, education, relationship status, and military status), pain-related factors (pain symptoms, severity, interference, and cognitions), other physical factors (e.g., common illness), opioid-medication-related factors (receipt of opioid medications and quantity of opioid medications), behavioral factors (substance use disorder, alcohol use, cigarette use, and other prescription drug use), and psychological factors (psychiatric symptoms and cognitive factors). CONCLUSIONS POM was prevalent in veterans and military and could be potentially influenced by multiple psycho-behavioral factors. Future research guided by a theoretical framework is warranted to examine psycho-behavioral influences on POM and their mechanisms and to inform effective psychosocial POM interventions in veterans and military.

Abstract
Students' use of prescription stimulants to enhance study performance is increasingly under the spotlight. Medical guidelines discourage general practitioners (GPs) from prescribing stimulants to students without a diagnosis; yet a considerable proportion of students acquire them from GPs. Building on Eisenberg's theoretical framework on clinical decision-making and Conrad's sociological concept of biomedical enhancement, this study examined the social context of GPs' off-label prescribing decisions for stimulants, using data from 21 semi-structured interviews, including vignettes, undertaken with Flemish GPs. Results identified two groups of GPs: (1) hard-liners who strictly follow medical guidelines and who would only prescribe in case of an appropriate diagnosis and (2) context-dependent GPs who would prescribe stimulants depending on the patients' symptoms and extent of need. GPs' decisions depend on one-on-one doctor-patient interactions (i.e. the extent of empathy from the doctor and the extent of assertiveness from the patient); the extent to which GPs define concentration problems as medical problems; GPs' interactions with fellow health care workers; as well as GPs' interaction with the wider community. By disentangling these influences, this paper advances both theoretical and practical understanding of the sociological context in which GPs' off-label prescribing behaviour occurs.

Abstract
INTRODUCTION People's motivations for nonmedical use of prescription drugs (NMUPD) are not well studied, particularly in longitudinal representative samples. However, understanding which motivations are most popular and how these change over time for specific groups is important to inform interventions for NMUPD. METHODS The current study examined how young adults' motives for NMUPD changed over young adulthood, using a nationally representative sample of 12,223 young adults in 36 cohorts (1976-2012) as part of the Monitoring the Future study across three biennial waves (waves 1, 2, 3: modal ages 19/20, 21/22, and 23/24 years). We investigated these young adults' motivations for using stimulants, central nervous system depressants, and opioids when controlling for possible cohort effects. We included sex and college attendance as potential moderators. RESULTS Participants commonly reported recreational and self-treatment motivations over time and across drug classes, reporting four to five popular motivations in each drug class. Generalized estimating equations repeated measure analyses revealed relatively stable NMUPD motivations across young adulthood. Participants reported some reductions in experimentation and boredom as motivations for NMUPD and increases in certain self-treatment motivations, depending on prescription drug class. Overall, men were more likely to endorse recreational motivations, whereas women were more likely to endorse self-treatment motivations, though this varied somewhat by prescription drug class. Young adults not enrolled in college courses were more likely to endorse using stimulants nonmedically for different reasons than their peers who were enrolled. CONCLUSIONS NMUPD prevention and treatment efforts tailored to the young adult population should include methods to reduce both self-treatment and recreational use and need to consider prescription drug class, sex, and college attendance.

Abstract
BACKGROUND Attention deficit hyperactivity (ADHD) disorder is a neurodevelopmental disorder characterized by inattention, hyperactivity, disruptive behaviour, and impulsivity. Despite considered typical of children for a long time, the persistence of ADHD symptoms in adulthood gained increasing interest during the last decades. Indeed, its diagnosis, albeit controversial, is rarely carried out even because ADHD is often comorbid with several other psychiatric diosrders, in particular with bipolar disorders (BDs), a condition that complicates the clinical picture, assessment and treatment. AIMS The aim of this paper was to systematically review the scientific literature on the neurobiological, clinical features and current pharmacological management of ADHD comorbid with BDs across the entire lifespan, with a major focus on the adulthood. DISCUSSION The pharmacology of ADHD-BD in adults is still empirical and influenced by the individual experience of the clinicians. Stimulants are endowed of a prompt efficacy and safety, whilst non-stimulants are useful when a substance abuse history is detected, although they require some weeks in order to be fully effective. In any case, an in-depth diagnostic and clinical evaluation of the single individual is mandatory. CONCLUSION The comorbidity of ADHD with BD is still a controversial matter, as it is the notion of adult ADHD as a distinct nosological category. Indeed, some findings highlighted the presence of common neurobiological mechanisms and overlapping clinical features, although disagreement does exist. In any case, while expecting to disentangle this crucial question, a correct management of this comorbidity is essential, which requires the co-administration of mood stabilizers. Further controlled clinical studies in large samples of adult ADHD-BD patients appear extremely urgent in order to better define possible therapeutic guidelines, as well as alternative approaches for this potentially invalidating condition.

Abstract
Objectives: Non-medical use of prescription drugs (NMUPD) has become a threat to public health. In the United States, NMUPD is especially common in young adults (aged 18-25). Self-esteem is a robust psychosocial factor of substance use. The substance use literature also documents that self-esteem is associated with alcohol use through other cognitive factors, such as coping. Given the important role of coping in substance use intervention, it is important to understand how coping alters mechanisms underlying the effects of self-esteem on NMUPD. However, little research has explored mediational mechanisms among self-esteem, coping, and NMUPD. The current study sought to examine a hypothesized mediation model among self-esteem, coping, and NMUPD in college students. Methods: Data were collected online from 1052 undergraduates (aged 18 to 25; 723 females) in a large public university in Virginia. Participants reported their past-three-month NMUPD (i.e. opioids, sedatives, anxiolytics, and stimulants), self-esteem, and coping (13 domains; e.g. active coping and self-blame). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to identify the factorial structure of coping. Structural equation modeling (SEM) was employed for examining the hypothesized mediation model. Results: EFA and CFA identified a two-factor structure of coping (i.e. adaptive coping and maladaptive coping). SEM suggested that adaptive coping together with maladaptive coping completely mediated the relationship between self-esteem and NMUPD. The goodness-of-fit indicators suggest a good model fit (RMSEA = .04; CFI = .95; TLI = .93; WRMR = 1.11). Conclusion: Self-esteem appears to be a protective factor for NMUPD in college students, and its relationship with NMUPD is mediated by two types of coping. Future interventions targetting NMUPD among college students should attend to self-esteem and coping.

Abstract
OBJECTIVE To review all literature on the nonmedical use (NMU) and diversion of prescription stimulants to better understand the characteristics, risk factors, and outcomes of NMU and to review risk-reduction strategies. METHOD We systematically searched PubMed, PsycINFO, and SCOPUS from inception to May 2018 for studies containing empirical data about NMU and diversion of prescription stimulants. Additional references identified by the authors were also assessed for inclusion. RESULTS A total of 111 studies met inclusion criteria. NMU and diversion of stimulants are highly prevalent; self-reported rates among population samples range from 2.1% to 58.7% and from 0.7% to 80.0%, respectively. A variety of terms are used to describe NMU, and most studies have examined college students. Although most NMU is oral, non-oral NMU also occurs. The majority of NMU is associated with no, or minor, medical effects; however, adverse medical outcomes, including death, occur in some individuals, particularly when administered by non-oral routes. Although academic and occupational performance enhancement are the most commonly cited motivations, there is little evidence that academic performance is improved by NMU in individuals without attention-deficit/hyperactivity disorder. CONCLUSION NMU of stimulants is a significant public health problem, especially in college students, but variations in the terms used to describe NMU and inconsistencies in the available data limit a better understanding of this problem. Further research is needed to develop methods to detect NMU, identify individuals at greatest risk, study routes of administration, and devise educational and other interventions to help reduce occurrence of NMU. Colleges should consider including NMU in academic integrity policies.

Abstract
Although some studies have examined the association between prescription opioid misuse and mental health outcomes, few studies have examined the effects of prescription opioid misuse on suicidal behaviors among adolescents. The objective of this study was to examine the association between prescription opioid misuse and suicidal ideation, suicide plan, and suicide attempt among adolescents. Data for this study came from the 2017 Youth Risk Behavior Surveillance System. A sample of 8830 adolescents aged 14-18 years (50.9% female) were analyzed using logistic regression with suicidal ideation, suicide plan, and suicide attempt as outcome variables and prescription opioid misuse as the main explanatory variable. Of the 8830 adolescents, 13.3% ever misused prescription opioids; 17.7% experienced suicidal ideation, 13.3% made a suicide plan, and 6.5% attempted suicide during the past 12 months. In the multivariate logistic regression models, adolescent students who misused prescription opioids were 1.50 times more likely to have experienced suicidal ideation, 1.44 times more likely to have made a suicide plan, and 1.58 times more likely to have attempted suicide during the past 12 months when compared to their counterparts who did not misuse prescription opioids. Other significant predictors of suicidal behaviors include sexual minority, history of sexual assault, traditional bullying and cyberbullying victimization, feeling sad or hopeless, cigarette smoking, and illicit drug use. The findings of the present study demonstrate the harmful effects of prescription opioid misuse and its association with suicidal behaviors among adolescents.

Abstract
Background and aim Nonmedical use of prescription drugs needs particular attention. The aim of this study was to determine the prevalence of prescription-type opioids, methylphenidate and sedative-hypnotics use, and related factors in university students. Methods In this cross-sectional study, 524 students of Hormozgan University of Medical Sciences were selected by multi-stage sampling in 2016. A self-report questionnaire had been used examining substance use, religious beliefs and parental support. The questions about substance use were prepared based on the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test (WHO ASSIST). Religious beliefs were measured by Kendler's general religiosity questionnaire. Parental support was measured by the Persian version of Aneshensel and Sucoff's scale. All of the analysis was performed using Chi-square test, Fisher exact test, independent-samples t-test and binary logistic regression in SPSS 16 software. The level of significance was 0.05. Results The last year prevalence of prescription-type opioids, methylphenidate and sedative-hypnotics use was 16.1%, 3.3%, and 10.3%, respectively. The final model of logistic regression indicated hookah use (OR=2.5), methylphenidate use (OR=4.5), sedative-hypnotics use (OR=2.7), and were associated with students' prescription-type opioids use. The protective factor was familial support (OR=0.97) for prescription-type opioids use. Moreover, sedative-hypnotics use (OR=5.7) and illicit drug use (OR=27.6) were associated with methylphenidate use among students. Conclusions The results of this study showed that the prevalence of nonmedical use of prescription drugs is considerably high among students and is in need of interventions to reduce the prevalence of these drugs in universities.

Abstract
Our goal was to compare and contrast the correlates of academic- and recreation-motivated misuse of prescription stimulants (MPS). Questionnaires were distributed to a probability sample of students attending two universities. We used a series of logistic regression analyses to examine intrapersonal, interpersonal, and environmental correlates of use among academic-motivated users (versus nonacademic-motivated users) and recreation-motivated users (versus nonrecreation-motivated users; N = 257 students with MPS experience). Sensations seeking, older age, academic concern, family perception of MPS, family and faculty endorsement of MPS, perceived prevalence of MPS among friends, and financial stress were unique correlates of recreation-motivated MPS. Inattention, friends’ perception of MPS, friend endorsement of MPS, perception of willingness of health care providers to write prescriptions and negative expectancies were unique correlates of academic-motivated MPS. Variables that were correlates of both motives were race/ethnicity, year in school, avoidance self-efficacy, diversion, positive MPS expectancies, MPS intention, and other substance use. These findings have important prevention and intervention implications.

Abstract
BACKGROUND AND OBJECTIVES Relatively little is known about the neuropsychological profiles of college students who misuse prescription stimulant medications. METHODS Data presented are from college students aged 18-28 years who misused prescription stimulants prescribed for attention-deficit/hyperactivity disorder and controls (no prescription stimulant misuse). Students were assessed neuropsychologically using the self-report Behavioral Rating Inventory of Executive Functioning (BRIEF-A), the Cambridge Automated Neuropsychological Test and Battery (CANTAB), and other tests of cognitive functioning. The analyses included 198 controls (age 20.7 ± 2.6 years) and 100 prescription stimulant misusers (age 20.7 ± 1.7 years). RESULTS On the BRIEF-A, misusers were more likely than controls to endorse greater dysfunction on 8 of 12 measures including Inhibition, Self Monitor, Initiation, Working Memory, and Plan/Organize, when adjusting for race and sex (all p's < .05). Similarly, when dichotomizing the BRIEF-A as abnormal (T score ≥ 65), misusers had more abnormalities on five of nine subscales, as well as all major indices (p's < .05). Misusers also performed worse on several subtests of the CANTAB and standardized cognitive battery (p's < .05). A proxy of prescription stimulant misuse frequency was positively correlated with greater executive dysfunction on the BRIEF-A. DISCUSSION AND CONCLUSIONS These data demonstrate elevated risk for neuropsychological dysfunction among students who misuse prescription stimulants compared to non-misusing peers. The presence of ADHD contributed significantly to these cognitive findings. Students who misuse prescription stimulants should be screened for neuropsychological dysfunction. SCIENTIFIC SIGNIFICANCE These data may better elucidate the neuropsychological profile of college-aged prescription stimulant misusers. (Am J Addict 2017;26:379-387).

Diversion of prescription stimulants among college students: An initial investigation of injunctive norms. Addict Behav 2017; 65:264-268.

Abstract
Nonmedical use of prescription stimulants (NMUPS) is an increasing problem among the college student population. Despite recent increases in stimulant prescriptions, little research has examined diversion of prescription stimulants among college students. The purpose of the current exploratory study was to compare normative beliefs about the frequency and motives of NMUPS among a college student sample. Participants were 121 college students who reported having a current prescription for a prescription stimulant. Participants completed online surveys and reported occasions of diversion behavior along with ratings of perceived approval for NMUPS and associated motives. Participants with a history of diversion were more likely to rate their close friends as more approving of more frequent NMUPS, and more approving of various motives for NMUPS. Perceived approval of NMUPS and NMUPS motives among parents and typical university students was similar across diversion groups, with parents and university students being rated as more approving of NMUPS for educational purposes. These findings extend the use of social norms theory to a new behavior while adding to our understanding how those who divert their medication differ from those who do not. Future studies should seek to establish a causal relationship between perceived approval for NMUPS and diversion behaviors. These findings also suggest that future research should focus on the feasibility and impact of social norms intervention for NMUPS and medication diversion.

Abstract
OBJECTIVE The nonmedical use of stimulants (misuse) in the college setting remains of utmost public health and clinical concern. The objective of this study was to evaluate comprehensively the characteristics of college students who misused stimulants, attending to rates of attention-deficit/hyperactivity disorder (ADHD), other psychopathology, and substance use disorders. METHODS The data presented are from a cross-sectional study of college students who misused prescription stimulant medications (not including cocaine or methamphetamine) and controls (college students without stimulant misuse). Between May 2010 and May 2013, college students were assessed blindly for psychopathology and substance use disorder by way of Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Research Version, Patient Edition (SCID-I/P) and completion of self-report questionnaires. RESULTS The analysis included 198 controls (mean ± SD age = 20.7 ± 2.6 years) and 100 stimulant misusers (20.7 ± 1.7 years). Misusers, when compared to controls, were more likely to endorse alcohol, drug, alcohol + drug, and any substance use disorder (all P values < .01). When a subset of stimulant misusers (n = 58) was examined, 67% had a full or subthreshold prescription stimulant use disorder. Misusers also had higher rates of conduct disorder (10% vs 3%; P = .02) and ADHD (including subthreshold cases; 27% vs 16%; P = .02) in addition to lower Global Assessment of Functioning score (P < .01). Higher rates of misuse of immediate-release—relative to extended-release—stimulants were reported. CONCLUSIONS Our data suggest that, compared to controls, college students who misuse stimulant medications are more likely to have ADHD, conduct disorder, stimulant and other substance use disorder, and overall dysfunction.

A systematic review of the motivations for the non-medical use of prescription drugs in young adults. Drug Alcohol Depend 2016; 162:3-25. [PMID: 26851986 DOI: 10.1016/j.drugalcdep.2016.01.011] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2015] [Revised: 01/12/2016] [Accepted: 01/17/2016] [Indexed: 01/10/2023]
Abstract
BACKGROUND Young adults (18-25) are most at-risk for the non-medical use of prescription drugs (NMUPD). Understanding this population's motivations for use can help inform efforts to reduce NMUPD. Therefore, this systematic review synthesizes the findings from research on young adults' motivations to engage in NMUPD. METHODS Based on PRISMA guidelines, relevant databases were systematically searched for articles that assessed the motivations for NMUPD in young adults and college-aged students. Search strings included a range of prescription drug classes and terms to ensure an exhaustive review. RESULTS The search resulted in identifying 353 potential articles after duplicates were removed, and 37 articles were included in the final qualitative synthesis. Of the final articles, the majority investigated the non-medical use of prescription stimulants in U.S. student populations cross-sectionally. Seven studies, either exclusively or in combination with other medications, researched prescription opioids, and five investigated central nervous system depressants. Only one study investigated motivations over time. CONCLUSION There are many ways in which the current literature can be expanded, including researching other populations and focusing on prescriptions other than stimulants. Using the medications for their prescribed properties and known side effects emerged as a consistent theme. It was also fairly common for young adults to report recreational motives. Issues with measurement and definitions of key terms (e.g., non-medical) would benefit from consistency in future work. Research on motivations should continue and be incorporated into the larger drug use context, as well as existing prevention and intervention strategies.

Abstract
The illicit use of prescription stimulants (IUPS) is a substance use behavior that remains prevalent on college campuses. As theory can guide research and practice, we provide a systematic review of the college-based IUPS epidemiological literature guided by one ecological framework, the theory of triadic influence (TTI). We aim to assess prevalence, elucidate the behavior's multietiological nature, and discuss prevention implications. Peer-reviewed studies were located through key phrase searches (prescription stimulant misuse and college, "prescription stimulant misuse" and "college," illicit use of prescription stimulants in college, and nonmedical prescription stimulant use in college students) in electronic databases (PubMed, PubMed Central, and EBSCO Host) for the period 2000 to 2013. Studies meeting inclusion criteria had their references reviewed for additional eligible literature. Statistically significant correlates of IUPS in the 62 retrieved studies were organized using the three streams of influence and four levels of causation specified in the TTI. Results show that the prevalence of IUPS varies across campuses. Additionally, findings suggest the behavior is multifaceted, as correlates were observed within each stream of influence and level of causation specified by the TTI. We conclude that IUPS is prevalent in, but varies across, colleges and is influenced by intrapersonal and broader social and societal factors. We discuss implications for prevention and directions for future research.

Abstract
This article presents ethnographic data on the use of prescription stimulants for enhancement purposes by university students in New York City. The study shows that students find stimulants a helpful tool in preventing procrastination, particularly in relation to feeling disinterested, overloaded, or insecure. Using stimulants, students seek pleasure in the study situation, for example, to get rid of unpleasant states of mind or intensify an already existing excitement. The article illustrates the notion that enhancement strategies do not only concern productivity in the quantitative sense of bettering results, performances, and opportunities. Students also measure their own success in terms of the qualitative experience of working hard. The article further argues that taking an ethnographic approach facilitates the study of norms in the making, as students experience moral uncertainty-not because they improve study skills and results-but because they enhance the study experience, making work fun. The article thereby seeks to nuance simplistic neoliberal ideas of personhood.

Abstract
AIMS As part of a larger study on prescription drug misuse among young adults active in urban nightlife scenes, we examined participants' motivations for misuse. Prescription painkillers, stimulants and sedatives were the primary substances of interest. METHODS Participants were recruited from nightlife venues in New York using time-space sampling. Subjects completed a mixed-methods assessment at project research offices. The data presented here are from a subsample of 70 qualitative interviews conducted during the baseline assessment. FINDINGS We identified experimentation and a "work hard, play hard" ethos as key motivations for misusing prescription drugs and argue that these motivations are specific, though not necessarily unique, to the participants' social location as young adults. These findings highlight the role of life stage and social context in the misuse of prescription drugs. CONCLUSION Future studies of prescription drug misuse should pay attention to the larger social contexts in which users are embedded and, therefore, make decisions about how and why to misuse. Moving beyond the very broad concepts of "recreation" and "self-medication" presently established in the research, policies targeting young adults may want to tailor intervention efforts based on motivations.

Abstract
This chapter reviews methylphenidate misuse, abuse, dependence, diversion, and malingering associated with its use as a prescription medication for attention-deficit/hyperactivity disorder and the nonmedical use linked to its stimulant effects. Methylphenidate-induced regional elevations in brain dopamine appear to be integral to both efficacy in attention-deficit/hyperactivity disorder and potential for abuse, raising potential concerns for drug safety and prescription drug diversion costs associated with nonmedical use. Regardless, methylphenidate is an important treatment option, and detecting malingering for the purpose of illicit access to methylphenidate for subsequent misuse or diversion is a difficult challenge. Also discussed are the effects of methylphenidate in patients with comorbid substance use disorder and the potential linkage of methylphenidate use with subsequent substance abuse. The current data suggest that methylphenidate misuse and diversion are common health-care problems with a stimulant prescription drug diversion prevalence of approximately 5-10 % of high school students and 5-35 % of college students. The effectiveness and speed of action of methylphenidate are deemed desirable to enhance attention and focus performance for activities such as studying for exams, but methylphenidate is also misused recreationally. These data suggest a need for close screening and therapeutic monitoring of methylphenidate use in the treatment of attention-deficit/hyperactivity disorder.

Abstract
OBJECTIVE To test a theory-driven model of health behavior to predict the illicit use of prescription stimulants (IUPS) among college students. PARTICIPANTS A probability sample of 554 students from one university located in California (response rate=90.52%). METHODS Students completed a paper-based survey developed with guidance from the Theory of Triadic Influence. We first assessed normality of measures and checked for multicollinearity. A single structural equation model of frequency of IUPS in college was then tested using constructs from the theory's three streams of influence (i.e., intrapersonal, social situation/context, and sociocultural environment) and four levels of causation (i.e., ultimate causes, distal influences, proximal predictors, and immediate precursors). RESULTS Approximately 18% of students reported engaging in IUPS during college, with frequency of use ranging from never to 40 or more times per academic term. The model tested had strong fit and the majority of paths specified within and across streams were significant at the p<0.01 level. Additionally, 46% of the variance in IUPS frequency was explained by the tested model. CONCLUSIONS Results suggest the utility of the TTI as an integrative model of health behavior, specifically in predicting IUPS, and provide insight on the need for multifaceted prevention and intervention efforts.

Abstract
RATIONALE Treatment of attention-deficit/hyperactivity disorder (ADHD) has for many years relied on psychostimulants, particularly various formulations of amphetamines and methylphenidate. These are central nervous system stimulants and are scheduled because of their abuse potential. Atomoxetine (atomoxetine hydrochloride; Strattera®) was approved in 2002 for treatment of ADHD, and was the first nonstimulant medication approved for this disorder. It was classified as an unscheduled medication indicating a low potential for abuse. However, the abuse potential of atomoxetine has not been reviewed. OBJECTIVES In this article, we review the evidence regarding abuse potential of atomoxetine, a selective inhibitor of the presynaptic norepinephrine transporter, which is unscheduled/unrestricted in all countries where it is approved. METHODS Results from receptor binding, in vitro electrophysiology, in vivo microdialysis, preclinical behavioral, and human laboratory studies have been reviewed. RESULTS Atomoxetine has no appreciable affinity for, or action at, central receptors through which drugs of abuse typically act, i.e., dopamine transporters, GABA(A) receptors, and opioid μ receptors. In behavioral experiments in rodents, atomoxetine does not increase locomotor activity, and in drug discrimination studies, its profile is similar to that of drugs without abuse potential. Atomoxetine does not serve as a reinforcer in monkey self-administration studies, and human laboratory studies suggest that atomoxetine does not induce subjective effects indicative of abuse. CONCLUSION Neurochemical, preclinical, and early clinical studies predicted and supported a lack of abuse potential of atomoxetine, which is consistent with the clinical trial and postmarketing spontaneous event data in the past 10 years.

Abstract
PURPOSE OF REVIEW The link between attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUDs) continues to be an area of great interest. In this report more recent work exploring the developmental relationship between ADHD and SUDs and associated concurrent disorders is discussed. RECENT FINDINGS Recent work highlights the role of treatment of ADHD in children on subsequent cigarette smoking and SUDs in adolescence and adulthood. Contemporary data suggest that ADHD may be underdiagnosed in SUD populations. Studies in patients with ADHD and SUDs suggest that SUDs treatment needs to be sequenced initially with ADHD treatment quickly thereafter. Recent studies also highlight concerns associated with the misuse and diversion of prescription stimulants in ADHD adolescents and young adults and indicate that extended-release stimulants may reduce the likelihood for abuse. SUMMARY Practitioners are increasingly recognizing the overlap between ADHD and SUDs, and treatment modalities including cognitive behavioral therapy and pharmacotherapy demonstrate mixed results in the treatment of these comorbid disorders. Areas in need of further investigation include the mechanism(s) by which ADHD leads to SUDs, diagnostic criteria associated with ADHD in SUD individuals, and prevention and treatment strategies for these populations.
