The use of mobile health (mHealth)-based interventions for the prevention of alcohol and other psychoactive substances use is an emerging practice for which new evidence is required. This study evaluated the feasibility and acceptability of a mHealth-based peer mentoring tool for early screening, brief intervention, and referral of students who abuse alcohol and other psychoactive substances. It compared the implementation of a mHealth-delivered intervention to the paper-based practice that is the standard at the University of Nairobi.
A quasi-experimental study using purposive sampling was used to select a cohort of n = 100 (51 experimental, 49 control) first-year student peer mentors on two campuses of the University of Nairobi in Kenya. Data were collected on the mentors' sociodemographic characteristics as well as the feasibility and acceptability of the interventions by way of, the magnitude of reach, feedback to investigators, referral of cases, and perceived ease of use.
The mHealth-based peer mentoring tool scored high with 100% of users rating it as feasible and acceptable. Among the two study cohorts, there were no differences in the acceptability of the peer mentoring intervention. When comparing the feasibility of the peer mentoring practice, actual use of the interventions, and intervention reach, the mHealth-based cohort mentored four mentees for every one mentored by the standard practice cohort.
The mHealth-based peer mentoring tool had high feasibility and acceptability among student peer mentors. The intervention provided evidence for the need to expand the availability of screening services for alcohol and other psychoactive substances use among students in the university and promote the appropriate management practices within and outside the university.

Participant Satisfaction and Acceptability of a Culturally Adapted Brief Intervention to Reduce Unhealthy Alcohol Use Among Latino Immigrant Men
2020
Latino immigrant men are at increased risk for unhealthy alcohol use, yet few interventions have been designed to meet their unique needs. The current study assessed participant satisfaction and acceptability of a culturally adapted brief intervention to reduce unhealthy alcohol use in this population. Adaptations to the brief intervention included delivering it in Spanish by promotores in a community setting. The mixed methods approach included surveys (N = 73) and in-depth interviews (N = 20) with participants in a pilot randomized controlled trial. The study drew on Sekhon’s theoretical framework of acceptability to asses affective attitude, burden, and perceived effectiveness of the intervention, along with satisfaction with the content, setting, and promotor. Participants’ survey responses indicated that they were highly satisfied with the content, setting, and delivery of the brief intervention. In interviews participants noted that the brief intervention helped them reflect on their drinking behaviors, that they perceived promotores to be a trusted source of health information, and that they liked receiving personalized feedback via tablets. Some participants found the feedback did not match their own perceptions of their alcohol use and wanted clearer advice on how to reduce their drinking. Men felt they would benefit from more contact with promotores. These findings suggest that Latino immigrant men in this study were receptive to the culturally adapted brief intervention. Future interventions may be more effective if they include multiple contacts with promotores and more directive guidance on strategies to reduce drinking.

Despite high rates of alcohol abstinence, Alaska Native and American Indian (ANAI) people experience a disproportionate burden of alcohol-related morbidity and mortality. Multiple barriers to treatment exist for this population, including a lack of culturally relevant resources; limited access to or delays in receiving treatment; and privacy concerns. Many ANAI people in the state of Alaska, United States, live in sparsely populated rural areas, where treatment access and privacy concerns regarding peer-support programs may be particularly challenging. In addition, prior research demonstrates that many ANAI people prefer a self-management approach to sobriety, rather than formal treatment. Taken together, these factors suggest a potential role for a culturally adapted smartphone app to support ANAI people interested in changing their behavior regarding alcohol use.
This study was the first phase of a feasibility and acceptability study of a culturally tailored version of an off-the-shelf smartphone app to aid ANAI people in managing or reducing their use of alcohol. The aim of this qualitative needs assessment was to gather insights and preferences from ANAI people and health care providers serving ANAI people to guide feature development, content selection, and cultural adaptation before a pilot test of the smartphone app with ANAI people.
From October 2018 to September 2019, we conducted semistructured interviews with 24 ANAI patients aged ≥21 years and 8 providers in a tribal health care organization in south-central Alaska.
Participants generally endorsed the usefulness of a smartphone app for alcohol self-management. They cited anonymity, 24/7 access, peer support, and patient choice as key attributes of an app. The desired cultural adaptations included ANAI- and land-themed design elements, cultural content (eg, stories from elders), and spiritual resources. Participants considered an app especially useful for rural-dwelling ANAI people, as well as those who lack timely access to treatment services or prefer to work toward managing their alcohol use outside the clinical setting.
This needs assessment identified key features, content, and cultural adaptations that are being implemented in the next phase of the study. In future work, we will determine the extent to which these changes can be accommodated in a commercially available app, the feasibility of implementation, and the acceptability of the culturally adapted version of the app among ANAI users.

Prior efforts to estimate U.S. prevalence of substance use disorders (SUDs) in HIV care have been undermined by caveats common to single-site trials. The current work reports on a cohort of 10,652 HIV-positive adults linked to care at seven sites, with available patient data including geography, demography, and risk factor indices, and with substance-specific SUDs identified via self-report instruments with validated diagnostic thresholds. Generalized estimating equations also tested patient indices as SUD predictors. Findings were: (1) a 48 % SUD prevalence rate (between-site range of 21–71 %), with 20 % of the sample evidencing polysubstance use disorder; (2) substance-specific SUD rates of 31 % for marijuana, 19 % alcohol, 13 % methamphetamine, 11 % cocaine, and 4 % opiate; and (3) emergence of younger age and male gender as robust SUD predictors. Findings suggest high rates at which SUDs occur among patients at these urban HIV care sites, detail substance-specific SUD rates, and identify at-risk patient subgroups.

Differences in Tobacco Product Use Among Past Month Adult Marijuana Users and Nonusers
2016
This study assessed differences in individual tobacco product use between past month marijuana users and nonusers, and trends in overall tobacco use and use of specific tobacco products among marijuana users.
Data were obtained from 378 459 adults participating in the 2003-2012 National Survey on Drug Use and Health, a cross-sectional, household interview survey conducted annually. Data from the most recent 2 years (2011-2012) were used to assess differences in the prevalence of various tobacco products by past month marijuana status. Data from all years were used to assess historical trends in overall tobacco use, and use of cigarettes, cigars, and blunts among marijuana users; trend significance was assessed using orthogonal polynomials.
From 2011-2012, the prevalence of any past month tobacco use among the 9727 past month marijuana users was 68.6% excluding blunts, and 78.3% including blunts (vs. 25.3% for nonusers, P < .0001); 77.3% of past month marijuana users reported past month combusted tobacco use (vs. 23.4% of non-MJ users, P < .0001). By product, 60.1% of past month marijuana users reported past month cigarette use, 42.0% reported past month blunt use, and 20.6% reported past month cigar use. Overall, adjusted trends in past month cigarette use decreased, while trends in past month blunt use increased; cigar use did not change.
Tobacco use is highly prevalent among adult marijuana users and represents an important potential comorbidity of marijuana use. In light of increasing policies legalizing marijuana, it is critical to monitor changes in overall and specific tobacco product use.

BackgroundOpioid overdose is a major and increasing cause of injury and death. There is an urgent need for interventions to reduce overdose events among high-risk persons.MethodsAdults at elevated risk for opioid overdose involving heroin or pharmaceutical opioids who had been cared for in an emergency department (ED) were randomised to overdose education combined with a brief behavioural intervention and take-home naloxone or usual care. Outcomes included: (1) time to first opioid overdose-related event resulting in medical attention or death using competing risks survival analysis; and (2) ED visit and hospitalisation rates, using negative binomial regression and adjusting for time at risk.ResultsDuring the follow-up period, 24% of the 241 participants had at least one overdose event, 85% had one or more ED visits and 55% had at least one hospitalisation, with no significant differences between intervention and comparison groups. The instantaneous risk of an overdose event was not significantly lower for the intervention group (sub-HR: 0.83; 95% CI 0.49 to 1.40).DiscussionThese null findings may be due in part to the severity of the population in terms of housing insecurity (70% impermanently housed), drug use, unemployment and acute healthcare issues. Given the high overdose and healthcare utilisation rates, more intensive interventions, such as direct referral and provision of housing and opioid agonist treatment medications, may be necessary to have a substantial impact on opioid overdoses for this high-acuity population in acute care settings.Trial registration numberNCT0178830; Results.

Abstract
Although Latino immigrant men experience many health disparities, they are underrepresented in research to understand and address disparities. Community Based Participatory Research (CBPR) has been identified to encourage participant engagement and increase representation in health disparities research. The CBPR conceptual model describes how partnership processes and study design impact participant engagement in research. Using this model, we sought to describe how these domains influenced participant engagement in a pilot randomized controlled trial of brief intervention for unhealthy alcohol use (n = 121) among Latino immigrant men. We conducted interviews with a sample of study participants (n = 25) and reviewed logs maintained by ‘promotores’. We identified facilitators of participant engagement, including the relevance of the study topic, alignment with participants’ goals to improve their lives, partnerships with study staff that treated participants respectfully and offered access to resources. Further, men reported that the study time and location were convenient and that they appreciated being compensated for their time. Barriers to participant engagement included survey questions that were difficult to understand and competing demands of work responsibilities. Findings suggest that engaging underserved communities requires culturally responsive and community engagement strategies that promote trust. Future studies should further investigate how CBPR partnership processes can inform intervention research.

Substance use disorders (SUDs) are thought to predict care discontinuity, though magnitude and substance-specific variance of effects are unclear. This report of analytic work undertaken with a multi-regional American cohort of 9153 care enrollees addresses these gaps. Care retention was computed from 24-month post-linkage clinic visit documentation, with SUD cases identified from patient-report screening instruments. Two generalized estimating equations tested binary and hierarchial SUD predictors of retention, and potential effect modification by patient age-group, sex, and care site. Findings demonstrate: (1) detrimental SUD effect, equivalent to a nine percentage-point decrease in retention, with independent effects of age-group and care site; (2) substance-specific effect of marijuana UD associated with lower retention; and (3) age-modification of each effect on care discontinuity, with SUDs serving as a risk factor among 18–29 year-olds and protective factor among 60+ year-olds. Collective findings document patient attributes as influences that place particular subgroups at-risk to discontinue care.

Prison, a missing target to address issues related to drug detoxification and rehabilitation: Nepalese experiences
2013
Purpose - Drug use has numerous consequences on health, the economy, culture and the peace and security of families and communities. Drug users often engage in various criminal activities, including drug dealing, to sustain their drug use. Under Nepalese law, consumption, possession and sale of drugs are illegal, which increases the risk of incarceration for drug users. Design/methodology/approach - Using a phenomenological/qualitative approach, the paper explores how various activities can lead to the arrest of drug users, how they cope without taking drugs in custody and prison and how they plan abstinence after release. Findings - Participants engaged in various categories of criminal activity, including stealing, looting, etc. Most of the drug users were in custody and prison at least once. Drug use relapses led the participants to re-engage in criminal activities including drug dealing. Parents were often overburdened by their sons and daughter's drug use and were worried about their repeated relapses. Finally, some parents negotiated with their sons and daughters to keep them in prison where they would be able to stay without taking drugs and their involvement in crimes and conflicts would decrease. Originality/value - Keeping substance abusers in prison does not appear to be an effective strategy, as many participants relapse after release from prison. However, a prison-based educational and health promotion strategy would be beneficial for drug users to develop knowledge and skills on staying drug-free. However, to date, no effort has been made to provide such services to drug users and develop their coping strategy after release.
