Pill-poppers and dopers: a comparison of non-medical prescription drug use and illicit/street drug use among college students

Digital interventions for substance use disorders in young people: rapid review

BACKGROUND

Young people are disproportionately more likely than other age groups to use substances. The rise in substance use and related harms, including overdose, during the Covid-19 pandemic has created a critical need for more innovative and accessible substance use interventions. Digital interventions have shown effectiveness and can provide more engaging, less stigmatizing, and accessible interventions that meet the needs of young people. This review provides an overview of recent literature on the nature of recently published digital interventions for young people in terms of technologies used, substances targeted, intended outcomes and theoretical or therapeutic models employed.

METHODS

Rapid review methodology was used to identify and assess the literature on digital interventions for young people. An initial keyword search was conducted using MEDLINE the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), Health Technology Assessment Database (HTA) and PROSPERO for the years 2015-2020, and later updated to December 2021. Following a title/abstract and full-text screening of articles, and consensus decision on study inclusion, the data extraction process proceeded using an extraction grid developed for the study. Data synthesis relied on an adapted conceptual framework by Stockings, et al. that involved a three-level treatment spectrum for youth substance use (prevention, early intervention, and treatment) for any type of substance.

RESULTS

In total, the review identified 43 articles describing 39 different digital interventions. Most were early interventions (n = 28), followed by prevention interventions (n = 6) and treatment interventions (n = 5). The identified digital technologies included web-based (n = 14), game-based (n = 10), mobile-based (n = 7), and computer-based (n = 5) technologies, and virtual reality (n = 3). Most interventions targeted alcohol use (n = 20) followed by tobacco/nicotine (n = 5), cannabis (n = 2), opioids (n = 2), ketamine (1) and multiple, or any substances (n = 9). Most interventions used a personalized or normative feedback approach and aimed to effect behaviour change as the intended outcome. Interestingly, a harm reduction approach guided only one of the 39 interventions.

CONCLUSIONS

While web-based interventions represented the most common type of technology, more recently developed immersive and interactive technologies such as virtual reality and game-based interventions call for further exploration. Digital interventions focused mainly on alcohol use, reflecting less concern for tobacco, cannabis, co-occurring substance use, and illicit drug use. Specifically, the recent exacerbation in the opioid crisis throughout North American underlines the urgent need for more prevention-oriented digital interventions for opioid use. The uptake of digital interventions among youth also depends on the incorporation of harm reduction approaches.

Birds of a Feather Get High Together: A Reconceptualization of the Social Bond with Latent Class Analysis and a Test with Different Forms of Drug Use

Social bond theory has received significant empirical support in examinations of drug use for decades. However, research utilizing the theory has often been fragmented and has not incorporated all four dimensions of the social bond. Additionally, much of this research has collapsed drug use into categories rather than examining specific forms of drug use. These concerns confuse the theoretical and practical insights that may be derived from such analyses. I utilize Monitoring the Future (2019) data to examine social bonding wholistically as latent classes in line with the concept of the social bond described by Hirschi (1969) and estimate the effect of the classes on specific forms of drug use. I find there are four distinct classes of social bonding among U.S. seniors most clearly differentiated by levels of attachment and commitment. Logistic regression results indicated different classes of social bonding were associated with different forms of drug use. I discuss the theoretical implications of the results and how they can be applied for criminal justice practitioners.

Illicit drug use among college students: The role of social norms and risk perceptions

PURPOSE

To examine the prevalence and correlates of college student use of illicit substances including cocaine, designer drugs, and nonmedical use of prescription stimulants and opioids, and to identify how different drug-related perceptions are related to past year use of these substances.

METHODS

Data were analyzed from a cross-sectional anonymous web-based survey among a sample (n = 1345, 81% female) of students attending a mid-sized liberal arts college in the US. Logistic regression models were estimated to assess the relationships between substance-specific descriptive norms, injunctive norms, perceived availability, risk perceptions and past year use of cocaine, designer drugs, prescription stimulants, and opioids, adjusting for current marijuana use, alcohol dependence, sensation seeking, and sociodemographic factors.

FINDINGS

Past year use of illicit substances ranged from 6% for nonmedical prescription opioids to 21% for nonmedical prescription stimulants. The sociodemographic correlates past year substance use differed by substance type. Descriptive norms (perceptions of peer use) and perceived risk were not consistently related to use of these substances. Current marijuana use was the strongest correlate across substances, and both injunctive norms (perceptions of peer approval) and perceived availability were consistently related to use of each substance.

CONCLUSIONS

Findings suggest that future college student drug prevention efforts should more directly target current marijuana users since they are most at risk of using other illicit substances. Additionally, findings indicate that injunctive norms may be an important consideration for education-focused drug prevention programs. However, findings should be interpreted in light of limitations of the sample, which is predominantly female.

Heavy Drinking and Non-Medical Use of Prescription Drugs among University Students: A 9-Year Follow-Up

Purpose: Investigations suggest non-medical use of prescription drugs (NMUPD) is associated with heavy drinking and polydrug use among university students. Our aim is to determine the prevalence of NMUPD among university students and to analyze its association with alcohol, tobacco, and cannabis use, and to study the role of the age of drinking onset. Methods: Cohort study among university Spanish students (n = 1382). Heavy drinking (HED) and risky consumption (RC) were measured with the Alcohol Use Disorders Identification Test. Questions related to tobacco and cannabis consumption were also formulated. NMUPD refers to sedative, anxiety, or pain medication intake within the last 15 days without medical prescription. All variables were measured at 18, 20, and 27 years. Multilevel logistic regression for repeated measures was used to obtain adjusted OR (odds ratios). We analyzed the results from a gender perspective. Results: Prevalence of NMUPD were higher in students who already partook in NMUPD at the beginning of the study. NMUPD in women at 27 is 3 times higher than at 18, while in men it is twice. Among females, RC (OR = 1.43) and cannabis consumption (OR = 1.33) are risk factors for NMUPD, while later onset of alcohol use (OR = 0.66) constitutes a protective factor. No significant differences were found for males. Conclusions: NMUPD is prevalent among university students. RC and early onset of alcohol use were associated with higher prevalence of NMUPD in females. The prevalence of NMUPD increased with age in both sexes. Strategies for reducing risky drinking and delaying onset of drinking should be provided for university students. Pharmacists and parents should be alerted to the risk of NMUPD.

The impact of a theory-based web-intervention on the intention to use prescription drugs for non-medical purposes among college students: a randomized controlled trial

The non-medical use of prescription drugs (NMUPD) among college students is escalating at an alarming rate. A limited number of studies have utilized a theoretical framework to influence this behavior. To utilize the reasoned-action approach theory to design and evaluate a web-based intervention to influence students' attitudes, perceived norms (PNs), perceived behavioral control (PBC) and intentions toward NMUPD. Using a two-group post-test only controlled trial, students were randomized to view either a general health website or a web-based intervention focused on NMUPD. The intervention was presented in multiple sections to address each component of the reasoned-action approach. Subsequently, respondents completed a web-survey. Independent t-tests were used to compare responses between the two groups. Of 391 respondents, 112 (28.9%) students indicated previous NMUPD. The intervention group had significantly (P = 0.04) more negative attitudes toward NMUPD. No significant differences were found in PNs (P = 0.11), PBC (P = 0.68) or intentions to NMUPD (P = 0.97). The intervention was successful in changing attitudes toward NMUPD. Targeting the intervention toward college students regardless of previous experiences of NMUPD might have led to insufficiency of the intervention to influence intentions. Additional research is needed to improve the intervention dissemination and utilization.

If Everyone Is Doing It, It Must Be Safe: College Students' Development of Attitudes toward Poly-Substance Use

Background: While binge drinking on college campuses has been a topic of concern for decades, especially among fraternity and sorority members, recreational drug use is on the rise and mixing alcohol and drugs is now more of a concern than ever. Objective: Social learning theory was used as a framework for understanding how students develop attitudes regarding the possible risks and rewards of various behaviors such as binge drinking and drug use. Method: This research reports the results of 13 focus group discussions with 63 college students. A thematic approach was used and revealed several themes: participating in college culture, experimenting is expected, ignoring risk-taking, and resisting peer pressure. Findings: Participants felt as if it was expected that college students would experiment with alcohol and drugs, and that it was just "part of going away to college." Students reported ignoring the known risks of mixing alcohol and drugs use despite prior education efforts. Conclusions: The findings of this study suggest that alcohol and drug use on college campuses is, at least in part, driven by a perception of college culture and a poor balancing of the risks and rewards associated with these behaviors.

Disability status and prescription drug misuse among U.S. adults

BACKGROUND

The U.S. is in the midst of a public health crisis related to drug overdose deaths. Largely responsible for the dramatic increase in overdose deaths is the misuse of prescription drugs such as opioids and benzodiazepines. While much research attention has focused on correlates of prescription drug misuse in recent years, notable gaps in the literature remain. The current research addresses one of these gaps by examining the relationship between disability status and prescription drug misuse.

METHOD

We examine data from the 2015 National Survey on Drug use and Health, a leading source of epidemiological data on drug use in the United States that added questions related to disability status to the 2015 survey. The current research assessed the relationship between disability status (i.e. activities of daily living and instrumental activities of daily living) and prescription drug misuse (i.e. opioids and benzodiazepines) among adults.

RESULTS

Findings from multinomial logistic regression analysis showed that a disability related to activities of daily living was correlated with opioid misuse, while a disability associated with instrumental activities of daily living was associated with benzodiazepine misuse and misuse of both. In addition, health related measures had a greater impact on the relationship between disability status and prescription drug misuse than did the social engagement/isolation measures.

CONCLUSION

Findings indicated that disability status is a significant correlate of prescription drug misuse. However, this relationship was largely mediated by measures associated with poor health and social engagement/isolation.

Nonmedical Use of Prescription Drugs among Medical Students and the Relationship With Illicit Drug, Tobacco, and Alcohol Use

Nonmedical use of prescription medications is a growing health problem including not only the opioid painkiller overdose epidemic but also benzodiazepine and stimulants misuse. Medical students express considerable high percentages of prescription drug misuse but also of illicit drug use, with cannabis being the frequently used illicit drug. We report the final results of a cross-sectional study among medical students that examined prevalence and motivation for use and suggest that medical students display similar patterns of misuse, for both licit and illicit drugs, to other students. Furthermore, a correlation was found between illicit drugs use with tranquilizers misuse and between smoking and alcohol misuse with opioids, sleeping drugs, and stimulants use. Considering that substance use during medical school affects students’ personal and professional lives and has potential consequences for their patients, further studies are needed to elucidate the prevalence but also the motivation for that use.

Illict drug use and academia in North Kosovo: Prevalence, patterns, predictors and health-related quality of life

PURPOSE

The purpose of this study were to estimate the prevalence and patterns of illicit drug use in a sample of University students from North Kosovo, to assess factors associated with illicit drug use and to assess health-related quality of life (HRQoL) among students according to illicit drug use.

METHODS

A cross-sectional study was conducted at the Student Public Health Center, where 514 University students were enrolled from April to June 2015 in North Kosovo. Participants completed the general socio-demographic and behavioral questionnaire, Beck Depression Inventory (BDI) and the SF-36 questionnaire for HRQoL assessment. Data on lifetime illicit drug use were self-reported.

RESULTS

As much as 16.0% of students reported ever illicit drug use. The most frequently used drugs were marijuana (9.3%) and bromazepam (7.6%). Factors associated with ever illicit drug use were: being smoker and alcohol user, having chronic diseases and having higher depressive symptoms score. Ever illicit drug users reported all domains of HRQoL as worse.

CONCLUSION

These results could serve as a tool for implementation of preventive strategies and University policies to promote healthy lifestyles and behaviors. Measurement of HRQoL could also be used as indicator of the effect of interventions designed to reduce and/or prevent illicit drug use at institutions of higher education.

Racial/ethnic variation in mental health correlates of substance use among college students

This study investigated mental health indicators, substance use, and their relationships, by race/ethnicity. A probability sample of 1,053 students at two California universities self-reported their frequency of substance use and rated their experience with indicators of mental health. One-way analysis of variance (ANOVA), chi-square tests, and multivariate censored regression models were estimated to examine which indicators of mental health were associated with each substance use form by race/ethnicity. Results from the one-way ANOVA and chi-square tests showed differences in substance use prevalence and mental health by race/ethnicity. For example, students who identified as White demonstrate a higher prevalence for every form of substance use in comparison to the Asian, Latino, and "All other" categories. Results from the regression showed, among Whites, inattention was associated with prescription stimulant misuse, and psychological distress was associated with marijuana use. Among Latinos, inattention was associated with cocaine and prescription stimulant use. Among Asians, psychological distress was associated with tobacco use and the misuse of prescription painkillers. Findings highlight the need to ensure subpopulations receive needed services.

Non-medical use of prescription drugs by young men: impact of potentially traumatic events and of social-environmental stressors

Background: Non-medical use of prescription drugs (NMUPD) is an increasing phenomenon associated with physical and psychological consequences. This study investigated the effects of distinct forms of stress on NMUPD. Methods: Data from 5308 young adult men from the Swiss cohort study on substance use risk factors (C-SURF) were analysed regarding NMUPD of sleeping pills, tranquilizers, opioid analgesics, psychostimulants, and antidepressants. Various forms of stress (discrete, potentially traumatic events, recent and long-lasting social-environmental stressors) during the period preceding the NMUPD assessment were measured. Backward log-binomial regression was performed and risk ratios (RR) were calculated. Results: NMUPD was significantly associated with the cumulative number of potentially traumatic events (e.g. for opioid analgesics, RR = 1.92, p < .001), with problems within the family (e.g. for sleeping pills, RR = 2.45, p < .001), and the peer group (e.g. for tranquilizer use, RR = 2.34, p < .01). Factors describing family functioning in childhood showed very few significant associations. Sexual assault by acquaintances was associated only with use of sleeping pills (RR = 2.91, p p <.01); physical assault by acquaintances was not associated with NMUPD. Physical (e.g. for psychostimulants, RR = 2.01, p < .001) or sexual assaults (e.g. for antidepressants, RR = 4.64, p < .001) perpetrated outside the family context did show associations with several drug categories. Conclusion: NMUPD appears to be more consistently associated with discrete and potentially traumatic events and with recent social-environmental stressors than with long-lasting stressors due to family functioning during childhood and youth. Physical and sexual assaults perpetrated by strangers showed more associations with NMUPD than those perpetrated by a family member.

Profile of female patients seeking in-patient treatment for prescription opioid abuse from a tertiary care drug dependence treatment centre from India

Background & objectives:

There has been a limited focus on prescription drug abuse among women in the country. Choice of psychoactive substance, reasons for initiation and co-occurring disorders have been found to be different among men and women. The current study was aimed at studying the profile of female patients seeking in-patient treatment for prescription drug use over a period of five years at a tertiary care drug dependence treatment centre in India.

Methods:

Case records of all female patients admitted with substance use disorder at a national level drug dependence treatment centre in north India across five years (between January 2008 and December 2012) were reviewed retrospectively to study their socio-demographic and clinical profile. The information was gathered using a semi-structured proforma and detailed case records. Abstinence, relapse and retention rates were calculated.

Results:

Over the five years, 31 female patients were admitted with prescription drug abuse. Of them, 12 (39%) used prescription opioids and 11 (36%) used prescription opioid along with benzodiazepines. Commonest prescription opioid was pentazocine used by 87 per cent of the women. Twenty two (71%) women were introduced to opioid by medical practitioners and commonest reason for introduction was pain (among 48%). Common co-occurring psychiatric diagnoses were depressive disorder (26%), cluster B traits/disorder (19%) and somatoform disorder (13%). Eight women did not complete treatment and left against medical advice. Thirteen women were advised maintenance treatment, and 70 per cent of them were retained for at least six months.

Interpretation & conclusions:

Our findings revealed a link between mental illness, pain and non-medical use of prescription opioids among women. Majority of these women received opioids as a legitimate prescription form physician. Therefore, these legitimate prescribers should be trained for pain management to facilitate proper treatment of pain and to prevent the subsequent misuse of these medicines. Female patients with frequent pain complaints should be assessed for psychopathology while prescribing opioids.

Prescription Drug Misuse Among College Students

Prescription drug misuse (PDM) is a well-documented trend among college students, with a rising prevalence in recent years. Motivations for PDM are an important aspect of the dynamics surrounding this behavior. Using a sample of undergraduate students taken from a large southern university ( N = 841), this study separates users based on their motives into typologies of instrumental, recreational, or mixed motive users and examines the differences between them using a number of social learning, social control, and strain-based risk factors while also comparing them with non-users. The results show that social learning risk factors, specifically those related to the concepts of differential association and differential reinforcement, as well as the use of other drugs, exert the greatest impact on likelihood of PDM between the motivational typologies.

Alcohol Interventions Among Underage Drinkers in the ED: A Randomized Controlled Trial

OBJECTIVES

This study examined the efficacy of emergency department (ED)-based brief interventions (BIs), delivered by a computer or therapist, with and without a post-ED session, on alcohol consumption and consequences over 12 months.

METHODS

Patients (ages 14-20 years) screening positive for risky drinking were randomized to: BI (n = 277), therapist BI (n = 278), or control (n = 281). After the 3-month follow-up, participants were randomized to receive a post-ED BI session or control. Incorporating motivational interviewing, the BIs addressed alcohol consumption and consequences, including driving under the influence (DUI), and alcohol-related injury, as well as other concomitant drug use. The computer BI was an offline, Facebook-styled program.

RESULTS

Among 4389 patients screened, 1054 patients reported risky drinking and 836 were enrolled in the randomized controlled trial. Regression models examined the main effects of the intervention conditions (versus control) and the interaction effects (ED condition × post-ED condition) on primary outcomes. The therapist and computer BIs significantly reduced consumption at 3 months, consequences at 3 and 12 months, and prescription drug use at 12 months; the computer BI reduced the frequency of DUI at 12 months; and the therapist BI reduced the frequency of alcohol-related injury at 12 months. The post-ED session reduced alcohol consequences at 6 months, benefiting those who had not received a BI in the ED.

CONCLUSIONS

A single-session BI, delivered by a computer or therapist in the ED, shows promise for underage drinkers. Findings for the fully automated stand-alone computer BI are particularly appealing given the ease of future implementation.

Motivations for Prescription Drug Misuse among Young Adults: Considering Social and Developmental Contexts

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.

Predicting students' intention to use stimulants for academic performance enhancement

BACKGROUND

The non-medical use of stimulants for academic performance enhancement is becoming a more common practice among college and university students.

OBJECTIVE

The objective of this study is to gain a better understanding of students' intention to use stimulant medication for the purpose of enhancing their academic performance. Based on an extended model of Ajzen's theory of planned behavior, we examined the predictive value of attitude, subjective norm, perceived behavioral control, psychological distress, procrastination, substance use, and alcohol use on students' intention to use stimulants to improve their academic performance.

METHODS

The sample consisted of 3,589 Flemish university and college students (mean age: 21.59, SD: 4.09), who participated anonymously in an online survey conducted in March and April 2013. Structural equation modeling was used to investigate the relationships among the study variables.

RESULTS

Our results indicate that subjective norm is the strongest predictor of students' intention to use stimulant medication, followed by attitude and perceived behavioral control. To a lesser extent, procrastinating tendencies, psychological distress, and substance abuse contribute to students' intention. Conclusions/ Importance: Based on these findings, we provide several recommendations on how to curtail students' intention to use stimulant medication for the purpose of improving their academic performance. In addition, we urge researchers to identify other psychological variables that might be related to students' intention.

Prescription drug misuse and gender

In recent years, prescription drug misuse has become a serious public health issue. A number of studies in this area have identified females to be at an increased risk for prescription drug misuse during adolescence. Guided by Agnew's general strain theory, the current research examined the relationship between prescription drug misuse and gender during adolescence. We used data from the 2010 National Survey on Drug Use and Health, a sample representative of the non-institutionalized population of the United States. Logistic regression models were estimated to examine the relationship between gender, prescription drug misuse, strain, and depression. The findings indicated that females were at an increased for prescription drug misuse. We also found support for general strain theory, as strain and depression were significantly related to prescription drug misuse. In addition, we found evidence that strain was gendered in that elements of general strain theory accounted for the relationship between prescription drug misuse and gender.

Prescription drug misuse and sexual risk behaviors among adolescents and emerging adults

OBJECTIVE

The purpose of this study was to evaluate associations between prescription drug misuse (PDM) and sexual risk behaviors (SRBs) among adolescents and emerging adults.

METHOD

In a hospital emergency department, 2,127 sexually active 14- to 20-year-olds (61% female) reported on past-year alcohol use severity (using the Alcohol Use Disorders Identification Test-consumption [AUDIT-C]), cannabis use, PDM (n = 422), and SRBs (inconsistent condom use, multiple partners, intercourse following alcohol/other drug use).

RESULTS

Bivariately, AUDIT-C score, cannabis use, and PDM of stimulants, opioids, and sedatives were positively associated with each SRB. Because many participants reported PDM for multiple drug classes (i.e., sedatives, stimulants, opioids), participants were categorized as (a) no PDM (n = 1,705), (b) PDM of one class (n = 251), (c) PDM of two classes (n = 90), or (d) PDM of three classes (n = 81). Three hierarchical logistic regression models evaluated the associations of number of classes of PDM with SRBs separately, after accounting for demographics (age, gender, race), AUDIT-C score, and cannabis use. Adding PDM statistically improved each model beyond what was accounted for by demographics, alcohol, and cannabis use. For inconsistent condom use and substance use before sex, PDM of one, two, or three classes was significantly associated with increased odds of these SRBs. PDM of two or three classes was associated with increased odds of reporting multiple partners.

CONCLUSIONS

Findings suggest that PDM, especially poly-PDM, may be a pertinent risk factor for SRBs among youth. Event-based research could further evaluate how PDM, as well as other substance use, is related to SRBs at the event level in order to inform interventions.

Coping and emotion regulation profiles as predictors of nonmedical prescription drug and illicit drug use among high-risk young adults

BACKGROUND

Deficits in the ability to organize, integrate, and modulate emotions, thoughts, and behaviors when dealing with stress have been found to be related to the onset and escalation of substance use among adolescents and young adults. However, limited research has focused on understanding how coping and emotion regulation tendencies might be associated with different patterns of prescription and illicit drug use, particularly among high-risk young adults who may already face additional challenges relative to lower-risk populations.

METHODS

Young adults aged 16-25 years who had misused prescription drugs within the past 90 days were interviewed in Los Angeles and New York. The current study utilized latent profile analysis to empirically derive coping and emotion regulation typologies/profiles that are then used to predict different patterns of substance use (N=560).

RESULTS

Four latent classes/groups were identified: (1) suppressors, (2) others-reliant copers, (3) self-reliant copers and (4) active copers. Distinct patterns of prescription and illicit drug misuse were found among different coping/emotion regulation profiles, including differences in age of initiation of opiates, tranquilizers, and illicit drugs, recent injection drug use, substance use-related problems, and past 90-day use of tranquilizers, heroin, and cocaine. Specifically, suppressors and others-reliant copers evidenced more problematic patterns of substance use compared to active copers.

CONCLUSION

This is among the first studies to show how coping and emotion regulation profiles predict distinct patterns of substance use. Results provide the groundwork for additional investigations that could have significant prevention and clinical implications for substance-using high-risk young adults.

Tweaking and tweeting: exploring Twitter for nonmedical use of a psychostimulant drug (Adderall) among college students

Background

Adderall is the most commonly abused prescription stimulant among college students. Social media provides a real-time avenue for monitoring public health, specifically for this population.

Objective

This study explores discussion of Adderall on Twitter to identify variations in volume around college exam periods, differences across sets of colleges and universities, and commonly mentioned side effects and co-ingested substances.

Methods

Public-facing Twitter status messages containing the term “Adderall” were monitored from November 2011 to May 2012. Tweets were examined for mention of side effects and other commonly abused substances. Tweets from likely students containing GPS data were identified with clusters of nearby colleges and universities for regional comparison.

Results

213,633 tweets from 132,099 unique user accounts mentioned “Adderall.” The number of Adderall tweets peaked during traditional college and university final exam periods. Rates of Adderall tweeters were highest among college and university clusters in the northeast and south regions of the United States. 27,473 (12.9%) mentioned an alternative motive (eg, study aid) in the same tweet. The most common substances mentioned with Adderall were alcohol (4.8%) and stimulants (4.7%), and the most common side effects were sleep deprivation (5.0%) and loss of appetite (2.6%).

Conclusions

Twitter posts confirm the use of Adderall as a study aid among college students. Adderall discussions through social media such as Twitter may contribute to normative behavior regarding its abuse.

Understanding nonprescription and prescription drug misuse in late adolescence/young adulthood

This study explored the extent to which nonprescription and prescription drugs misuse among adolescents/young adults are related to their perception that it is safer than illicit drugs, ease of access, and lower societal stigma. Adolescents/young adults (N = 465; M_age = 18.57, SD = 0.86) completed an online survey about their nonprescription and prescription drug misuse, other substance use, and correlates of use. Perceived risk, societal stigma, and access to nonprescription and prescription drugs were predictive of misuse. Results support program planners working towards targeting perceived risk and societal stigma in reducing misuse and the need to restrict and monitor access to nonprescription and prescription drugs for adolescents/young adults.

Parent and peer influence on recreational use of pain medication: are their influences similar to that of marijuana use?

Parent and peer disapproval were examined as potential predictors of recreational use of over-the-counter (OTC) and prescription pain medication. Risk perception was studied as a potential mediator of the effects of parent and peer disapproval. Four hundred and sixty-five college students (M_age = 18.57, SD = 0.86) were recruited between September 2009 and September 2010. Participants completed an online survey about their recreational medication use, other substance use, and correlates of use. Path analyses showed that predictors of OTC and prescription pain medication recreational use are largely similar to predictors of marijuana use in college students such that risk perception mediated both the effect of parent and peer disapproval on dichotomous misuse, and peer disapproval had a significant direct effect on dichotomous misuse. Prevention interventions for recreational use of pain medication should target risk perception and peer disapproval.

Misuse of prescription and illicit drugs among high-risk young adults in Los Angeles and New York

Background

Prescription drug misuse among young adults is increasingly viewed as a public health concern, yet most research has focused on student populations and excluded high-risk groups. Furthermore, research on populations who report recent prescription drug misuse is limited. This study examined patterns of prescription drug misuse among high-risk young adults in Los Angeles (LA) and New York (NY), which represent different local markets for illicit and prescription drugs.

Design and Methods

Between 2009 and 2011, 596 young adults (16 to 25 years old) who had misused prescription drugs within the past 90 days were interviewed in Los Angeles and New York. Sampling was stratified to enroll three groups of high-risk young adults: injection drug users (IDUs); homeless persons; and polydrug users.

Results

In both sites, lifetime history of receiving a prescription for an opioid, tranquilizer, or stimulant was high and commonly preceded misuse. Moreover, initiation of opioids occurred before heroin and initiation of prescription stimulants happened prior to illicit stimulants. NY participants more frequently misused oxycodone, heroin, and cocaine, and LA participants more frequently misused codeine, marijuana, and methamphetamine. Combining prescription and illicit drugs during drug using events was commonly reported in both sites. Opioids and tranquilizers were used as substitutes for other drugs, e.g., heroin, when these drugs were not available.

Conclusion

Patterns of drug use among high-risk young adults in Los Angeles and New York appear to be linked to differences in local markets in each city for illicit drugs and diverted prescription drugs.

The Co-Ingestion of Nonmedical Prescription Drugs and Alcohol: A Partial Test of Social Learning Theory

Over the last decade, scholars have examined simultaneous polydrug use among illicit drug users; however, the co-ingestion of nonmedical prescription drug (NMPD) use and alcohol has been largely overlooked. Also overlooked have been the incorporation and testing of theoretical explanations for this type of substance use behavior. In the current paper, we test social learning theory as an explanation for NMPD use and the co-ingestion of nonmedical prescription drugs and alcohol on a Midwest university sample using a bivariate probit equation model. Support is found for the influence of differential association, social reinforcement, and definitions of use on the co-ingestion of NMPDs and alcohol.

Non-medical use of prescription drugs in a national sample of college women

Non-medical use of prescription drugs (NMUPD) is one of the fastest growing forms of illicit drug use, with research indicating that college students represent a particularly high risk population. The current study examined demographic characteristics, health/mental health, substance misuse, and rape experiences as potential risk correlates of NMUPD among a national sample of college women (N=2000). Interviews were conducted via telephone using Computer-Assisted Telephone Interviewing technology. NMUPD was assessed by asking if, participants had used a prescription drug non-medically in the past year. NMUPD was endorsed by 7.8% of the sample (n=155). Although incapacitated and drug-alcohol facilitated rape were associated with NMUPD in the initial model, the final multivariable model showed that only lifetime major depression and other forms of substance use/abuse were significantly uniquely associated with an increased likelihood of NMUPD. Implications for primary and secondary prevention and subsequent research are addressed.

Prescription drug misuse among Asian-American adults: results from a national survey

Asians have low levels of substance use compared with other groups in the United States. Given the increase in Asian population, we believe it is important to study substance use in this population. Data from the 2002-2003 National Latino and Asian American Study are examined to address two questions. First, which Asian ethnic subgroup is at greatest risk for prescription drug misuse? Second, is acculturation significantly correlated with prescription drug misuse among Asians? Findings indicate that Filipinos are at the greater risk for prescription drug misuse. Also, Asians who are more acculturated are at greater risk for prescription drug misuse.

The relationship between source of diversion and prescription drug misuse, abuse, and dependence

The current research examines the relationship between how people obtain prescription drugs (source of diversion) and how people misuse prescription drugs (i.e., frequency, abuse, and dependence). We analyzed data from the 2008 National Survey on Drug Use and Health public use file, a sample of 68,736 persons aged 12 and older that is generalizable to the noninstitutionalized population of the United States. A number of regression models were estimated, and findings indicate that source of diversion was significantly correlated to frequency of prescription drug misuse, abuse, and dependence. Given these findings, we believe any attempt to classify prescription drug misusers based on certain characteristics should include source of diversion.

What matters most? Assessing the influence of demographic characteristics, college-specific risk factors, and poly-drug use on nonmedical prescription drug use

OBJECTIVE

Although prior recent research has revealed a significant relationship between the nonmedical use of prescription drugs, demographic characteristics, college-specific risk factors, and other substance use among college students, there remains a need to conduct a comparative analysis on the differential impact these factors may have on predicting nonmedical prescription drug use.

PARTICIPANTS AND METHODS

In 2008 a convenience sample of 599 undergraduate students attending a southeastern university completed a self-report survey measuring substance use behaviors.

RESULTS

Males, Greeks, and freshman were more likely than females, non-Greeks, and upperclassman to use nonmedical prescription drugs in the past year. Multivariate analyses, however, indicate that the excessive use of alcohol and other illicit drugs are more influential than demographic and college-specific risk factors.

CONCLUSION

Poly-drug use was found to be the most significant predictor of the use of nonmedical prescription drugs as compared to demographic and college-specific risk factors.

Nonmedical prescription drug use among US college students at a Midwest university: a partial test of social learning theory

We estimate the prevalence of nonmedical prescription drug (NMPD) use and test social learning theory as an explanation for NMPD use based upon data from a large pilot study. Data were collected from 465 college students at a Midwestern university in the USA using a self-administered questionnaire. The sample was predominantly white (88%), 43% were female and the mean age was 22. Most participants (80%) were not members of social fraternities or sororities. A majority of students did not report NMPD use: 39.4% of respondents reported lifetime NMPD use, 31% reported past-year use, and 14.4% reported past-month use. Multivariate regression results partially supported social learning theory as an explanation for lifetime NMPD use. Limitations and suggestions for future research are suggested.
