Do naloxone access laws affect perceived risk of heroin use? Evidence from national US data

BACKGROUND AND AIMS

Whether expanded access to naloxone reduces perceptions of risk about opioid use has been subject to debate. Our aim was to assess how implementation of naloxone access laws shapes perceived risk of heroin use.

DESIGN

Using data from the restricted-access National Survey on Drug Use and Health, Prescription Drug Abuse Policy System and the US Census, we applied two-way fixed-effects models to determine whether naloxone access laws decreased perceived risk of any heroin use or regular heroin use. We used Bayes factors (BFs) to confirm evidence for null findings.

SETTING

United States.

PARTICIPANTS

A total of 884 800 respondents aged 12 and older from 2004 to 2016.

MEASUREMENTS

A binary indicator of whether a state implemented naloxone access laws was regressed on respondent-perceived risk of (1) any heroin use and (2) regular heroin use. Ratings of perceived risk were assessed on a scale of 1 (none) to 4 (great risk).

FINDINGS

In all instances, the BFs support evidence for the null hypothesis. Across models with three distinct specifications of naloxone access laws, we found no evidence of decreased risk perceptions, as confirmed by BFs ranging from 0.009 to 0.057. Across models of specific vulnerable subgroups, such as people who use opioids (BFs = 0.039-0.225) or young people (BFs = 0.009-0.158), we found no evidence of decreased risk perceptions. Across diverse subpopulations by gender (BFs = 0.011-0.083), socio-economic status (BFs = 0.015-0.168) or race/ethnicity (BFs = 0.016-0.094), we found no evidence of decreased risk perceptions.

CONCLUSIONS

There appears to be no empirical evidence that implementation of naloxone access laws has adversely affected perceptions of risk of heroin in the broader US population or within vulnerable subgroups or diverse subpopulations.

Fentanyl Contamination as a Risk Priority: the Impact of the Fentanyl Epidemic on Club Drug-Using Behaviours

BACKGROUND

Over the last decade, rates of fentanyl-related overdoses have increased substantially across North America, a phenomenon which has widely been described as the "fentanyl epidemic." While research has explored the cultural impact of the fentanyl epidemic on opioid and/or injection drug use, less is known about its impact on other types of drug use. Drawing on two years of ethnographic research with people who use club drugs in Toronto's Electronic Dance Music (EDM) scene, this study looks at how people who use club drugs make sense of and respond to the fentanyl epidemic.

METHODS

Data for the study was collected via participant observation and semi-structured interviews (n = 26).

FINDINGS

The key finding was that fentanyl contamination had become a "risk priority" for the participants. They thereby adjusted their drug-using behaviors to account for this risk. However, by prioritizing fentanyl contamination above everything else, they often overlooked and/or disregarded other forms of harm reduction that they had once practiced (like getting testing kits to test for other adulterants).

CONCLUSION

The findings suggest that the fentanyl epidemic has impacted not only practices of illegal opioid use, but also practices of club drug use. They suggest that the fentanyl epidemic has in some ways facilitated the adoption of risk management, while in other ways undermined it. The findings are interpreted with reference to Rhodes' "risk environment" framework and with particular attention to the need for harm reduction interventions that take into consideration how risk perceptions and behaviors are situation- and context-dependent.

Influences of motivational contexts on prescription drug misuse and related drug problems

Prescription drug misuse has emerged as a significant problem among young adults. While the effects of motivational contexts have been demonstrated for illicit drugs, the role of motivational contexts in prescription drug misuse remains understudied. Using data from 400 young adults recruited via time-space sampling, we examined the role of motivational contexts in the frequency of misuse of three prescription drug types as well as drug-related problems and symptoms of dependency. Both negative and positive motivations to use drugs are associated with increases in prescription drug misuse frequency. Only negative motivations are associated directly with drug problems and drug dependence, as well as indirectly via prescription pain killer misuse. Addressing positive and negative motivational contexts of prescription drug misuse may not only provide a means to reduce misuse and implement harm reduction measures, but may also inform the content of treatment plans for young adults with prescription drug misuse problems.

Perceived risk of methamphetamine among Chinese methamphetamine users

BACKGROUND

Methamphetamine use has grown considerably in China in recent years. Information about perceptions of risk on methamphetamine is important to facilitate health promotion efforts.

METHODS

Using both survey data and qualitative interview data, the authors evaluate the perceived risk of methamphetamine use among Chinese users using a mixed-methods approach. Through Respondent Driven Sampling, the authors recruited a sample of 303 methamphetamine users in Changsha, China.

RESULTS

A majority (59.1%) perceive that infrequent methamphetamine use poses no risk to the user, while 11.2% perceive at least moderate risk for light use. A majority (56.7%) perceived at least moderate risk associated with regular methamphetamine use. Most (82.2%) also perceive methamphetamine to be easily obtainable. A path model indicates that perceived risk shapes intentions to use and expectations of future use, as does perceived availability. Qualitatively, while addiction was the most common risk discussed by users, they differed on whether they perceived the drug addictive. Other concerns raised by interviewees included impaired cognition, mental health problems, physical harm, and social dysfunction.

CONCLUSION

While some users identify significant risks with methamphetamine, others do not perceive its use to be problematic. Collectively, these findings indicate that intervening upon perceptions of risk among Chinese methamphetamine users may be a means to influence intentions to use.

Prescription drug misuse among young adults: looking across youth cultures

INTRODUCTION AND AIMS

Youth cultures play a key role in the social organisation of drug trends among young people; the current prescription drug misuse trend is no different. The authors evaluated whether patterns of prescription drug misuse differed across several youth cultures.

DESIGN AND METHODS

Using field survey methods and time-space sampling during 2011, the authors assessed the patterns and prevalence of prescription drug misuse among young adults who are socially active in various urban youth cultures (n = 1781).

RESULTS

The prevalence of lifetime prescription drug misuse is highest within indie rock scenes (52.5%), electronic dance music scenes (52.1%), lesbian parties (53.8%) and alt scenes (50.9%). Prescription drug misuse was lowest among young adults in hip-hop scenes (25.0%). These findings were upheld in logistic regression analyses that accounted for demographic differences across youth cultures: indie rock scenes (adjusted odds ratio = 2.11), electronic dance music scenes (adjusted odds ratio = 2.20), lesbian parties (adjusted odds ratio = 2.30) and alt scenes (adjusted odds ratio = 2.65) all reported statistically significant (P < 0.05) higher odds of misuse than college bar scenes. Recent prescription drug misuse mirrored patterns for lifetime misuse.

DISCUSSION AND CONCLUSIONS

The differing prevalence of prescription drug misuse across distinct youth cultures suggests that the trend has not diffused equally among young people. The differing prevalence across youth cultures indicates that the most efficacious strategies for youth intervention may be targeted approaches that account for the subculturally rooted differences in attitudes and social norms.

Correlates of concurrent energy drink and alcohol use among socially active adults

BACKGROUND

Research indicates that energy drink consumption and the combined use of energy drinks and alcohol are popular among young adults, although this research has typically focused on college students. Because of the potential for harms associated with this combination, it is critical to understand use among adults in nightlife scenes who may be most at risk for harms associated with combined energy drink and alcohol consumption.

OBJECTIVES

By focusing our sample on individuals in a range of nightlife scenes, we aim to gain a deeper understanding of the demographic factors associated with energy drink use and combined energy drink and alcohol consumption to benefit the targeting of intervention and prevention efforts beyond college campuses.

METHODS

Using a field-based survey in New York City to survey adults active in various nightlife scenes, this study reports on the survey results of 1476 venue patrons at venues in five nightlife scenes in addition to college bar scenes.

RESULTS

Men, younger individuals, Latinos, and sexual minority individuals reported higher prevalence of recent energy drink consumption. Younger individuals, men, and those recruited in gay venues reported higher prevalence of combining alcohol and energy drinks.

CONCLUSION

These findings provide information useful to target education and prevention efforts. They also suggest the need for additional research to understand differences in motivations for use and in the behavioral and alcohol-related outcomes associated with consuming energy drinks and combining them with alcohol.

Sampling and recruitment issues in qualitative drugs research: reflections on the study of club drug users in metro New York

This paper describes the role and implications of sampling and recruitment in qualitative drugs research. To provide further detail of some issues pertaining to sampling in qualitative and ethnographic projects, the author describes recent experiences utilizing theoretical sampling and time-space sampling to study club drug users. The author details practical challenges experienced with the implementation of these sampling methodologies and with the results they produced. Attention is paid to the role that the environmental factors at clubs play in the implementation of sampling methods, issues related to network methods in recruitment, and practical implications of managing team-based recruitment strategies.

Combining Different Substances in the Dance Scene: Enhancing Pleasure, Managing Risk and Timing Effects

Combining mind-altering substances, whether illegal or legal, has provoked calls of alarm and concern among drug researchers for over thirty years. Since then numerous studies have been conducted to trace the different prevalent combinations and emphasize the serious consequences for individuals who use two or more drugs at any given time. Recently, this concern has been heightened as a result of the evidence that polydrug use among young people is increasing, especially among those who attend electronic music dance parties. The aim of this paper is to explore the different drug combinations used by a group of young people who attend raves, clubs and dance parties in the San Francisco Bay Area. Based on in-depth interviews with 300 young people we explore not only the different substances combined, but the meanings given as to why such combinations are chosen. In exploring our respondents' accounts, we hope to highlight both the thinking behind their drug using practices and the range of procedures adopted by young people to enhance the pleasures they hope to achieve in taking different substances, and control any potential problems.

Careers in ecstasy use: do ecstasy users cease of their own accord? Implications for intervention development

Background

Ecstasy (MDMA, 3, 4-methylenodioxymethamphetamine) use is widespread in the Netherlands, with a lifetime prevalence of 4.3%, and two-thirds of dance party visitors being ecstasy users. However, research into Dutch ecstasy use patterns is lacking. In addition, recent studies suggest that ecstasy users cease their use automatically, which implies that interventions would do better to better focus on the promotion of harm reduction strategies than on inducing cessation. The current study addresses this process of ecstasy cessation.

Methods

32 participants from the Dutch dance scene were interviewed, and the results were systematically analysed using NVivo.

Results

Most ecstasy users had started to use out of curiosity. During use, users applied a host of harm reduction strategies, albeit inconsistently and sometimes incorrectly. Most users appeared to cease ecstasy use automatically because of loss of interest or changing life circumstances (e.g. a new job or relationship).

Conclusion

It appears that cessation of ecstasy use is largely determined by environmental variables and not by health concerns. This supports the idea that health promotion resources are better spent in trying to promote consistent and correct application of harm reduction practices than in trying to induce cessation.
