Abstract
BACKGROUND AND OBJECTIVES How best to measure the occurrence of adverse events during a randomized clinical trial is an issue that has not been adequately examined in the research literature. Focus of this study was on the examination of the relative frequency of occurrence of adverse events directly recorded during the conduct of the trial compared to an indirect determination of adverse events derived from data collected as part of the trial. METHODS A secondary analysis of nonserious adverse events that occurred in the Maternal Opioid Treatment: Human Experimental Research (MOTHER) Study was undertaken. MOTHER was a randomized clinical trial of methadone versus buprenorphine in 175 opioid-dependent pregnant women. RESULTS The two methods of recording adverse events failed to agree on where differences in the frequency of occurrence of adverse events between the medication conditions might exist. Moreover, indirect assessment indicated all participants had experienced at least one adverse event, yet indirect coverage of adverse events was incomplete. CONCLUSIONS Findings suggest indirect examination of occurrence of adverse events should be cautiously undertaken, because indirect assessment of adverse events makes no distinction between what might be simply typical variation in behavior rather than systematic changes in behavior attributable to study condition, and lacks coverage of the full spectrum of adverse events. SCIENTIFIC SIGNIFICANCE Contemporaneous direct measurement of adverse events likely yield reasonably valid estimates of the rate of occurrence of the adverse events, while indirect measu-rement of adverse events may not be sufficiently reliable.

Abstract
BACKGROUND It is well known that using false identification (ID) is a common method by which underage youth in the United States obtain alcohol. While false ID use is associated with high-risk drinking patterns, its association with alcohol use disorder (AUD), independent of other risk factors, has not been firmly established. METHODS Participants were 1,015 college students recruited from 1 university and assessed annually during their first 4 years of college. Latent variable growth curve modeling was used to identify significant predictors of false ID use and test the hypothesis that false ID use increased the risk for AUD, by increasing the frequency and/or quantity of alcohol use. Several other hypothesized risk factors for AUD were accounted for, including demographics (sex, race, living situation, religiosity, socioeconomic status), individual characteristics (childhood conduct problems, sensation-seeking, age at first drink), high school behaviors (high school drinking frequency, drug use), family factors (parental monitoring, parental alcohol problems), perception of peer drinking norms, and other factors related to false ID use. RESULTS False IDs were used by almost two-thirds (66.1%) of the sample. False ID use frequency was positively associated with baseline quantity and frequency of alcohol use, independent of all other factors tested. False ID use was not directly related to AUD risk, but indirectly predicted increases in AUD risk over time through its association with greater increases in alcohol use frequency over time. Several predictors of false ID use frequency were also identified. CONCLUSIONS False ID use may contribute to AUD risk by facilitating more frequent drinking. If replicated, these findings highlight the potential public health significance of policies that enforce sanctions against false ID use. Students who use false IDs represent an important target population for alcohol prevention activities.

Abstract
OBJECTIVE Until now, the functioning of the hypothalamic-pituitary-adrenal (HPA) axis in children with prenatal methamphetamine exposure (PME) had been unexamined. Previous research indicates that prenatal exposure to stimulant drugs is associated with dose-response alterations in neural growth and connectivity and consequent neurobehavioral deficits. In addition, children of drug-using parents are at an increased risk for exposure to chronic postnatal stress. In this preliminary study, we examined the associations of PME and postnatal environmental stress with cortisol stress reactivity in children with PME. METHOD Participants were 2-year-old children (N = 123; 55.3% male) with PME from a multicenter longitudinal Infant, Development, Environment, and Lifestyle Study. Saliva samples were obtained before and after a stress-inducing separation task. Hierarchical multiple regression analyses examined prenatal drug exposure, methodological and postnatal stress covariates, and interactions between levels of PME and postnatal stress. RESULTS Mild to moderate potential for child physical abuse moderated increased cortisol reactivity in high exposed children with PME. Blunted cortisol reactivity was associated with caregiver's postnatal alcohol use, child's behavioral dysregulation, and the interaction between higher levels of PME and caregiver's psychopathology. CONCLUSIONS Consistent with the known effects of stimulant drugs and chronically stressful environments on the HPA axis and, thus, the toxic stress and allostatic load phenomena, our results imply that elevated PME may be associated with alterations in the programming of the HPA axis reflecting hyperactivity, which under significant and chronic environmental stress then may become hypoactive.

Abstract
AIM This paper describes the goals and current practice of school-based random student drug testing (RSDT) as part of an overall drug prevention strategy, briefly explores the available literature evaluating its effectiveness and discusses the controversies related to RSDT. METHOD The authors describe the rationale for RSDT programs and the prevalence of RSDT and other drug testing programs in schools. Eight major criticisms and controversies in RSDT are discussed, including those related to acceptance of RSDT, program effectiveness, costs, legality and effects of drug testing on students. The limitations of the current literature are explored. FINDINGS Although there is limited empirical evidence to support or refute the efficacy of RSDT in schools, there remains substantial opposition to such programs, which may contribute to the paucity of empirical studies of RSDT. CONCLUSIONS Rigorous long-term evaluations are needed to evaluate the effectiveness of various versions of RSDT programs to prevent drug use and identify students in need of assistance to become and stay drug-free.

Abstract
This study compared patterns of prenatal care among mothers who used methamphetamine (MA) during pregnancy and non-using mothers in the US and New Zealand (NZ), and evaluated associations among maternal drug use, child protective services (CPS) referral, and inadequate prenatal care in both countries. The sample consisted of 182 mothers in the MA-Exposed and 196 in the Comparison groups in the US, and 107 mothers in the MA-Exposed and 112 in the Comparison groups in NZ. Positive toxicology results and/or maternal report of MA use during pregnancy were used to identify MA use. Information about sociodemographics, prenatal care and prenatal substance use was collected by maternal interview. MA-use during pregnancy is associated with lower socioeconomic status, single marital status, and CPS referral in both NZ and the US. Compared to their non-using counterparts, MA-using mothers in the US had significantly higher rates of inadequate prenatal care. No association was found between inadequate care and MA-use in NZ. In the US, inadequate prenatal care was associated with CPS referral, but not in NZ. Referral to CPS for drug use only composed 40 % of all referrals in the US, but only 15 % of referrals in NZ. In our study population, prenatal MA-use and CPS referral eclipse maternal sociodemographics in explanatory power for inadequate prenatal care. The predominant effect of CPS referral in the US is especially interesting, and should encourage further research on whether the US policy of mandatory reporting discourages drug-using mothers from seeking antenatal care.

Abstract
This study tested the hypothesis that college students' substance use problems would predict increases in skipping classes and declining academic performance, and that nonmedical use of prescription stimulants (NPS) for studying would occur in association with this decline. A cohort of 984 students in the College Life Study at a large public university in the US participated in a longitudinal prospective study. Interviewers assessed NPS; Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) cannabis and alcohol use disorders; and frequency of skipping class. Semester grade point average (GPA) was obtained from the university. Control variables were race, sex, family income, high school GPA, and self-reported attention deficit hyperactivity disorder diagnosis. Longitudinal growth curve modeling of four annual data waves estimated the associations among the rates of change of cannabis use disorder, percentage of classes skipped, and semester GPA. The associations between these trajectories and NPS for studying were then evaluated. A second structural model substituted alcohol use disorder for cannabis use disorder. More than one-third (38%) reported NPS for studying at least once by Year 4. Increases in skipping class were associated with both alcohol and cannabis use disorder, which were associated with declining GPA. The hypothesized relationships between these trajectories and NPS for studying were confirmed. These longitudinal findings suggest that escalation of substance use problems during college is related to increases in skipping class and to declining academic performance. NPS for studying is associated with academic difficulties. Although additional research is needed to investigate causal pathways, these results suggest that nonmedical users of prescription stimulants could benefit from a comprehensive drug and alcohol assessment to possibly mitigate future academic declines.

Abstract
OBJECTIVE This study examined the prospective relationship of substance use and mental health problems with risk of discontinuous enrollment in college. METHODS Participants were 1,145 students at a large public university who were interviewed annually for four years beginning at college entry in 2004 (year 1). Discontinuous enrollment was defined as a gap in enrollment of one or more semesters during the first two years (early discontinuity) or the second two years (late discontinuity) versus continuous enrollment throughout all four years. Explanatory variables measured in year 1 were scores on the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory, childhood conduct problems, cannabis use, number of illicit drugs used, and alcohol consumption. In years 3 and 4, participants reported lifetime history of clinically diagnosed attention-deficit hyperactivity disorder, depression, and anxiety, including age at diagnosis. Multinomial logistic regression models were developed to evaluate the association between the independent variables and discontinuous enrollment while holding constant background characteristics. RESULTS Higher BDI scores predicted early discontinuity but not late discontinuity, whereas cannabis and alcohol use predicted only late discontinuity. Receiving a depression diagnosis during college was associated with both early and late discontinuity. Self-reported precollege diagnoses were not related to discontinuous enrollment once background characteristics were taken into account. CONCLUSIONS Students who experience depressive symptoms or seek treatment for depression during college might be at risk of interruptions in their college enrollment. Cannabis use and heavy drinking appear to add to this risk. Students entering college with preexisting psychiatric diagnoses are not necessarily at risk of enrollment interruptions.

Abstract
Substance use disorder is a serious health problem that tends to manifest in late adolescence. Attempting to influence targetable risk and protective factors holds promise for prevention and treatment. Survey data from 1253 college students (48.5% male, 26.9% non-White) were used to investigate the independent and combined effects of two prominent factors, sensation seeking and parental monitoring, on the probability of alcohol and/or cannabis dependence during the first year of college. In multivariate analyses that controlled for high school use, gender, race, mother's education, and importance of religion, retrospective reports by the student of parental behavior during the last year of high school indicated that higher levels of parental monitoring had a direct effect on reducing risk for alcohol dependence during the first year of college, but not on cannabis dependence. High levels of sensation seeking were associated with increased risk for both alcohol and cannabis dependence. No interaction effects were found. The results extend prior findings by highlighting influences of pre-college parental monitoring and sensation seeking on the probability of alcohol and/or cannabis dependence during the first year of college. The findings also suggest that these two factors are useful in identifying college students at high risk for alcohol and/or cannabis dependence.

Abstract
BACKGROUND Methamphetamine (MA) abuse is a worldwide problem. Little is known about the co-morbidity of substance use disorders (SUD) and other psychiatric disorders of mothers who use MA prenatally. The Infant Development, Environment and Lifestyle (IDEAL) Study is a prospective, investigation of prenatal MA use and child outcome in the United States (US) and New Zealand (NZ). This study examined prenatal MA use and the co-morbidity of SUD and psychiatric disorders at 1-month postpartum. METHOD Mothers who used MA (US=127, NZ=97) were compared to a matched comparison group (US=193, NZ=110). The Substance Abuse Subtle Screening Inventory-3 was used to measure the probability of a SUD. The Brief Symptom Inventory (BSI) was used to measure the likelihood of a positive diagnosis of a psychiatric disorder. RESULTS In the US and NZ, MA groups had lower SES, increased single parenting, delayed prenatal care, and increased polydrug use. In the US only, MA mothers had lower income than the comparison group. MA users were 10 times more likely to have a SUD and twice as likely to meet BSI criteria for a diagnosable psychiatric disorder. In NZ, but not the US, MA users were five times more likely to have co-morbidity of both. This disparity may be due to higher quantities of prenatal alcohol use associated with increased psychiatric symptoms. CONCLUSION These findings suggest that addressing both substance abuse and psychiatric disorders in mothers who use MA may be required to effectively treat maternal MA use.

Abstract
OBJECTIVE Few longitudinal studies have examined the relationship between illicit drug use and academic outcomes among college students. This study characterized drug use patterns of a cohort of young adults who were originally enrolled as first-time, first-year college students in a longitudinal study. It evaluated the association between these drug use patterns and continuous enrollment during college, holding constant demographic characteristics, high school grade point average, fraternity/sorority involvement, personality/temperament characteristics, nicotine dependence, and alcohol use disorder. METHOD Participants (n = 1,133; 47% male) were purposively selected from one university and interviewed annually for 4 years, beginning with their first year of college, regardless of continued college attendance. Enrollment data were culled from administrative records. Group-based trajectory analyses characterized 4-year longitudinal drug use patterns. Two grouping variables were derived based on (a) marijuana use frequency and (b) number of illicit drugs used other than marijuana. Seventy-one percent of the sample was continuously enrolled in the home institution during the first 4 years of study. RESULTS Multivariable logistic regression models demonstrated that infrequent, increasing, and chronic/heavy marijuana use patterns were significantly associated with discontinuous enrollment (adjusted odds ratio = 1.66, 1.74, and 1.99, respectively), compared with minimal use, holding constant covariates. In separate models, drug use other than marijuana also was significantly associated with discontinuous enrollment. CONCLUSIONS Marijuana use and other illicit drug use are both associated with a decreased likelihood of continuous enrollment in college, independent of several other possible risk factors. These findings highlight the need for early intervention with illicit drug users to mitigate possible negative academic consequences.

Abstract
BACKGROUND The relationship between serious drug involvement and risk for unemployment is well recognized, but few studies have prospectively examined this relationship among college students. This study used longitudinal data to examine the association between drug use patterns during college and the likelihood of employment post-college, holding constant sociodemographic variables and personality characteristics. Second, we estimate the prevalence of alcohol and other drug use disorders among employed individuals. METHODS Data were derived from the College Life Study. Participants entered college as traditional students and were assessed annually for six years, regardless of continued college attendance. Analyses were restricted to 620 individuals no longer enrolled in school by Year 6. RESULTS Using multinomial regression modeling, persistent drug users (i.e., used illicit drugs (other than marijuana) and/or nonmedical prescription drugs every year they were assessed during the first four years of study) were significantly more likely than non-users to be unemployed vs. employed full-time post-college. Persistent drug users and infrequent marijuana users were also more likely than non-users to be unemployed vs. employed part-time. In Year 6, 13.2% of individuals employed full-time and 23.7% of individuals employed part-time met DSM-IV criteria for drug abuse or dependence during the past year. CONCLUSIONS If confirmed, the results of this study suggest that persistent drug use among academically achieving young adults might increase risk for post-college unemployment. More research is needed to understand the processes underlying this association. Further attention should be directed at managing substance use problems among recent college graduates who have secured employment.

Abstract
AIMS The Maternal Opioid Treatment: Human Experimental Research (MOTHER) project, an eight-site randomized, double-blind, double-dummy, flexible-dosing, parallel-group clinical trial is described. This study is the most current--and single most comprehensive--research effort to investigate the safety and efficacy of maternal and prenatal exposure to methadone and buprenorphine. METHODS The MOTHER study design is outlined, and its basic features are presented. CONCLUSIONS At least seven important lessons have been learned from the MOTHER study: (i) an interdisciplinary focus improves the design and methods of a randomized clinical trial; (ii) multiple sites in a clinical trial present continuing challenges to the investigative team due to variations in recruitment, patient populations and hospital practices that, in turn, differentially impact recruitment rates, treatment compliance and attrition; (iii) study design and protocols must be flexible in order to meet the unforeseen demands of both research and clinical management; (iv) staff turnover needs to be addressed with a proactive focus on both hiring and training; (v) the implementation of a protocol for the treatment of a particular disorder may identify important ancillary clinical issues worthy of investigation; (vi) timely tracking of data in a multi-site trial is both demanding and unforgiving; and (vii) complex multi-site trials pose unanticipated challenges that complicate the choice of statistical methods, thereby placing added demands on investigators to effectively communicate their results.

Abstract
AIMS To examine the relationship of anxiety and depression symptoms with treatment outcomes (treatment discontinuation, rates of ongoing use of illicit drugs and likelihood of preterm delivery) in opioid-dependent pregnant women and describe their use of psychotropic medications. DESIGN AND SETTING Secondary data analysis from a randomized clinical trial of treatment for opioid dependence during pregnancy. PARTICIPANTS A total of 175 opioid-dependent pregnant women, of whom 131 completed treatment. MEASUREMENTS Symptoms of anxiety and depression were captured with the 15-item Mini International Neuropsychiatric Interview (MINI) screen. Use of illicit drugs was measured by urine drug screening. Preterm delivery was defined as delivery prior to 37 weeks' gestation. Self-reported use of concomitant psychotropic medication at any point during the study was recorded. FINDINGS Women reporting only anxiety symptoms at study entry were more likely to discontinue treatment [adjusted odds ratio (OR) = 4.56, 95% confidence interval (CI) : 1.91-13.26, P = 0.012], while those reporting only depression symptoms were less likely to discontinue treatment (adjusted OR = 0.14, 95% CI : 0.20-0.88, P = 0.036) compared to women who reported neither depression nor anxiety symptoms. No statistically significant between-group differences were observed for ongoing illicit drug use or preterm delivery. A majority (61.4%) of women reported use of concomitant psychotropic medication at some point during study participation. CONCLUSIONS Opioid agonist-treated pregnant patients with co-occurring symptoms of anxiety require additional clinical resources to prevent premature discontinuation.

Abstract
AIMS This paper reviews the published literature regarding outcomes following maternal treatment with buprenorphine in five areas: maternal efficacy, fetal effects, neonatal effects, effects on breast milk and longer-term developmental effects. METHODS Within each outcome area, findings are summarized first for the three randomized clinical trials and then for the 44 non-randomized studies (i.e. prospective studies, case reports and series and retrospective chart reviews), only 28 of which involve independent samples. RESULTS Results indicate that maternal treatment with buprenorphine has comparable efficacy to methadone, although difficulties may exist with current buprenorphine induction methods. The available fetal data suggest buprenorphine results in less physiological suppression of fetal heart rate and movements than methadone. Regarding neonatal effects, perhaps the single definitive conclusion is that prenatal buprenorphine treatment results in a clinically significant less severe neonatal abstinence syndrome (NAS) than treatment with methadone. The limited research suggests that, like methadone, buprenorphine is compatible with breastfeeding. Data available thus far suggest that there are no deleterious effects of in utero buprenorphine exposure on infant development. CONCLUSIONS While buprenorphine produces a less severe neonatal abstinence syndrome than methadone, both methadone and buprenorphine are important parts of a complete comprehensive treatment approach for opioid-dependent pregnant women.

Abstract
AIMS To compare the profile of signs of neonatal abstinence syndrome (NAS) in methadone- versus buprenorphine-exposed infants. DESIGN, SETTING AND PARTICIPANTS Secondary analysis of NAS data from a multi-site, double-blind, double-dummy, flexible-dosing, randomized clinical trial. Data from a total of 129 neonates born to opioid-dependent women who had been assigned to receive methadone or buprenorphine treatment during pregnancy were examined. MEASUREMENTS For 10 days after delivery, neonates (methadone = 72, buprenorphine = 57) were assessed regularly using a 19-item modified Finnegan scale. Data from neonates who required pharmacological treatment (methadone = 41, buprenorphine = 27) were included up to the time treatment was initiated. The incidence and mean severity of the total NAS score and each individual sign of NAS were calculated and compared between medication conditions, as was the median time until morphine treatment initiation among treated infants in each condition. FINDINGS Two NAS signs (undisturbed tremors and hyperactive Moro reflex) were observed significantly more frequently in methadone-exposed neonates and three (nasal stuffiness, sneezing, loose stools) were observed more frequently in buprenorphine-exposed neonates. Mean severity scores on the total NAS score and five individual signs (disturbed and undisturbed tremors, hyperactive Moro reflex, excessive irritability, failure to thrive) were significantly higher among methadone-exposed neonates, while sneezing was higher among buprenorphine-exposed neonates. Among treated neonates, methadone-exposed infants required treatment significantly earlier than buprenorphine-exposed infants (36 versus 59 hours postnatal, respectively). CONCLUSIONS The profile of neonatal abstinence syndrome differs in methadone- versus buprenorphine-exposed neonates, with significant differences in incidence, severity and treatment initiation time. Overall, methadone-exposed neonates have a more severe neonatal abstinence syndrome.

Abstract
BACKGROUND Despite the relatively high prevalence of marijuana use among college students, little information exists regarding health outcomes associated with different use patterns or trajectories. METHODS Seven annual personal interviews (years 1-7) were administered to 1253 individuals, beginning in their first year in college. Growth mixture modeling was used to identify trajectories of marijuana, alcohol, and tobacco use frequency during years 1-6. Logistic regression was used to evaluate the relationship between marijuana use trajectories and several year 7 health outcomes, holding constant year 1 health, demographics, and alcohol and tobacco use trajectories. RESULTS Six marijuana use trajectories were identified: non-use (71.5% (wt) of students), low-stable (10.0% (wt)), late-increase (4.7% (wt)), early-decline (4.3% (wt)), college-peak (5.4% (wt)), and chronic (4.2% (wt)). The six marijuana trajectory groups were not significantly different on year 1 health-related variables, but differed on all ten year 7 health outcomes tested, including functional impairment due to injury, illness, or emotional problems; general health rating; psychiatric symptoms; health-related quality of life; and service utilization for physical and mental health problems. Non-users fared significantly better than most of the marijuana-using trajectory groups on every outcome tested. Chronic and late-increase users had the worst health outcomes. CONCLUSIONS Marijuana use patterns change considerably during college and the post-college period. Marijuana-using students appear to be at risk for adverse health outcomes, especially if they increase or sustain a frequent pattern of use.

Abstract
Prevalence and correlates of HIV testing were examined in a sample of 957 unmarried recent college students in the United States. Participants were asked about HIV testing, past-six-months sexual activities, lifetime treatment for sexually transmitted infections (STI), past-year health service utilization, and DSM-IV criteria for alcohol and other drug (AOD) dependence during the 2008-2009 academic year. Two in five (41.9%(wt)) were ever tested for HIV. Holding constant demographics, HIV testing was positively related to AOD dependence, frequency of unprotected sex, number of sex partners, having a physical exam by a medical professional, number of visits to a health provider for physical health problems, and lifetime STI treatment. Women were more likely than men to be tested for HIV despite similar levels of risky sex. Results demonstrate the feasibility of achieving high HIV testing rates in a college population.

Abstract
OBJECTIVE This study examines racial/ethnic differences in the prevalence, patterns, and correlates of co-occurring substance use and mental disorders (COD) among Whites, Blacks, Latinos, and Asians using data from the Collaborative Psychiatric Epidemiology Studies. METHOD We first estimated the prevalence of various combinations of different co-occurring depressive and anxiety disorders among respondents with alcohol, drug, and any substance use (alcohol or drug) disorders in each racial/ethnic group. We then estimated the prevalence of different patterns of onset and different psychosocial correlates among individuals with COD of different racial/ethnic groups. We used weighted linear and logistic regression analysis controlling for key demographics to test the effect of race/ethnicity. Tests of differences between specific racial/ethnic subgroups were only conducted if the overall test of race was significant. RESULTS Rates of COD varied significantly by race/ethnicity. Approximately 8.2% of Whites, 5.4% of Blacks, 5.8% of Latinos, and 2.1% of Asians met criteria for lifetime COD. Whites were more likely than persons in each of the other groups to have lifetime COD. Irrespective of race/ethnicity, most of those with COD reported that symptoms of mental disorders occurred before symptoms of substance use disorders. Only rates of unemployment and history of psychiatric hospitalization among individuals with COD were found to vary significantly by racial/ethnic group. CONCLUSIONS Our findings underscore the need to further examine the factors underlying differences between minority and nonminority individuals with COD as well as how these differences might affect help seeking and utilization of substance abuse and mental health services.

Abstract
BACKGROUND Previous research has suggested important contextual factors that can differentiate problem and nonproblem drinkers. OBJECTIVES To evaluate the strength of the prospective association between social contexts of drinking and subsequent alcohol use disorder and drunk driving 2-3 years later. METHODS The sample consisted of 652 individuals who were originally recruited at college entry, had complete data on at least one social context subscale, met the minimum criteria for Year 1 drinking, and had nonmissing data on at least one of the outcome variables in Years 3 and/or 4. Social contexts of drinking were assessed in Year 1 by using previously validated scales measuring six different situational and motivational contexts in which alcohol is consumed. DSM-IV criteria for alcohol abuse and dependence and drunk driving were assessed annually. RESULTS Holding constant gender, race/ethnicity, and baseline drinking frequency, the frequency of drinking in a context of social facilitation, sex-seeking, or in a motor vehicle during Year 1 was significantly related to a greater likelihood of alcohol abuse, alcohol dependence, and drunk driving in Years 3 and/or 4. Drinking in a context of emotional pain was related to alcohol dependence and drunk driving but not to alcohol abuse. CONCLUSIONS The Social Context of Drinking Scales have utility for identifying students who are at risk for developing alcohol-related problems. SCIENTIFIC SIGNIFICANCE Identifying college students who might develop alcohol dependence requires an assessment of both situational and motivational factors that influence drinking, especially drinking in a motor vehicle.

Abstract
Marijuana is the most prevalent illicit drug used by adolescents and young adults, yet marijuana initiation is rarely studied past adolescence. The present study sought to advance our understanding of parent and peer influences on marijuana exposure opportunity and incident use during college. A sample of 1,253 students was assessed annually for 4 years starting with the summer prior to college entry. More than one-third (38%(wt)) of students had already used marijuana at least once prior to college entry; another 25%(wt) initiated use after starting college. Of the 360 students who did not use marijuana prior to college, 74% were offered marijuana during college; of these individuals, 54% initiated marijuana use. Both low levels of parental monitoring during the last year of high school and a high percentage of marijuana-using peers independently predicted marijuana exposure opportunity during college, holding constant demographics and other factors (AOR = 0.92, 95% CI = 0.88-0.96, p < .001 and AOR = 1.11, 95% CI = 1.08-1.14, p < .001, respectively). Among individuals with exposure opportunity, peer marijuana use (AOR = 1.04, 95% CI = 1.03-1.05, p < .001), but not parental monitoring, was associated with marijuana initiation. Results underscore that peer influences operate well into late adolescence and young adulthood and thus suggest the need for innovative peer-focused prevention strategies. Parental monitoring during high school appears to influence exposure opportunity in college; thus, parents should be encouraged to sustain rule-setting and communication about adolescent activities and friend selection throughout high school.

Abstract
The Western approach to addiction treatment involves a medical or disease orientation to understanding the onset, course, and management of addiction, and a clinical goal of abstinence or very significant reductions in drug use, usually with a combination of behavioral and pharmacological interventions. Even within this Western approach, and despite several consensually accepted features of addiction, a significant mismatch remains between what this culture has come to accept as the nature of the disease and how that same culture continues to treat the disease. This paper discusses the evolution of these Western concepts over the past decade without a corresponding evolution in the nature, duration, or evaluation standards for addiction treatment. (1) Here, we take the position that continuing care and adaptive treatment protocols, combining behavioral therapies, family and social supports, and, where needed, medications show much promise to address the typically chronic, relapsing, and heterogeneous nature of most cases of serious addiction. By extension, methods to evaluate effectiveness of addiction treatment should focus upon the functional status of patients during the course of their treatment instead of post-treatment, as is the evaluation practice used with most other chronic illnesses.

Abstract
INTRODUCTION Light and intermittent patterns of cigarette smoking are prevalent among U.S. college-aged individuals. It is unclear whether intermittent smokers maintain their use over time or are transitioning to daily use or nonuse, and whether they experience more adverse health outcomes than nonsmokers. METHODS This study examined the trajectories of tobacco cigarette smoking, their predictors, and health outcomes among students (N = 1,253) assessed during their first year of college (Y(1)) and annually thereafter (Y(2), Y(3), and Y(4)). RESULTS In Y(1), 3.4% smoked daily and 4.1% exhibited signs of dependence (first cigarette within 30 min of waking). Growth curve modeling identified five distinct smoking trajectories. After stable nonsmokers (71.5%(wt)), the low-stable smoking trajectory was the most common (13.3%(wt)), outnumbering both low-increasing (6.5%(wt)) and high-stable smokers (5.5%(wt)) by 2:1 and high-decreasing smokers (3.2%(wt)) by 4:1. The likelihood of maintaining a low level of smoking over time was inversely related to Y(1) smoking frequency. Few demographic, smoking, and alcohol use characteristics measured in Y(1) distinguished low-increasers from low-stable smokers or high-decreasers from high-stable smokers. By Y(4), high-stable smokers rated their health significantly worse than all others except low-increasers. High-stable smokers had the most Y(4) health problems (i.e., provider visits for health problems and days of illness-related impairment), but only among nonWhites. CONCLUSIONS Many college students smoke, but few smoke daily or are nicotine dependent. Intermittent smoking patterns are often stable throughout college and are associated with adverse health outcomes. Prevention strategies should be designed to mitigate the possible long-term health consequences of light and intermittent smoking.

Abstract
BACKGROUND Non-suicidal self-injury (NSSI) is the deliberate and direct injuring of body tissue without suicidal intent for purposes not socially sanctioned. Few studies have examined the correlates of NSSI among young adults. This study aimed to identify predictors of lifetime and past-year NSSI, and describe motives for NSSI and disclosure of NSSI to others. METHOD Interviews were conducted annually with 1081 students enrolled in the College Life Study, a prospective longitudinal study conducted at a large public mid-Atlantic university. NSSI characteristics were assessed at Year 4. Demographic and predictor variables were assessed during Years 1 to 4. Multivariate logistic regression models were used to identify correlates of lifetime NSSI and predictors of past-year NSSI. RESULTS The prevalence of past-year and lifetime NSSI was 2% and 7% respectively (>70% were female for both lifetime and past-year NSSI). Seven percent of NSSI cases self-injured once, whereas almost half self-injured six or more times. Independent predictors of past-year NSSI were maternal depression, non-heterosexual orientation, affective dysregulation and depression. Independent predictors of lifetime NSSI were depression, non-heterosexual orientation, paternal depression and female sex. One in six participants with NSSI had attempted suicide by young adulthood. The three most commonly reported motives for NSSI were mental distress, coping and situational stressors. Most (89%) told someone about their NSSI, most commonly a friend (68%). CONCLUSIONS This study identified unique predictors of NSSI, which should help to elucidate its etiology and has implications for early identification and interventions.
