Background

An increase in opioid-related overdoses, notably from potent synthetic opioids like fentanyl, prompted this consideration of characteristics of emergency department (ED) patients with evidence for illicit fentanyl use or exposure, the correlation with intentional opioid misuse, and subsequent ED management.

Methods

A retrospective review was performed of patients presenting to an urban academic medical center ED with evidence for illicit fentanyl use, determined by positive urine drug screens (UDS), from 6/2021 through 11/2021. Participant demographics, comorbidities, ED chief complaint and disposition, and evidence of intentional opioid misuse were considered. Secondary outcomes included provision of buprenorphine/naloxone and/or naloxone kits at discharge, ED recidivism, and six-month mortality. Bivariate comparisons and logistic regression models were performed.

Results

Among 409 unique patients, most were white and male with a mean age of 39.4. Approximately half presented with opioid-related complaints. Evidence of intentional opioid misuse was identified in 72.6 % of patients. Black patients had 79 % lower odds of intentional opioid misuse compared to white patients. Regarding ED management, 28.8 % were discharged with buprenorphine/naloxone and 14.0 % with a naloxone kit. Black patients had 63 % lower odds of receiving buprenorphine/naloxone compared to white patients after controlling for covariates. Nearly 6 % of the study population died within six months of the initial ED visit.

Conclusion

This fentanyl-focused review describes patient characteristics which largely mirror the epidemiology of the current opioid epidemic; however, despite evidence of objective exposure, it also suggests that Black patients may be less likely to use fentanyl intentionally. It also highlights potential disparities related to ED-based opioid misuse patient management.

Introduction

Both electronic cigarette (e-cigarette) and social media use among youth are public health concerns. While the health impacts of extensive social media use and frequent use of e-cigarettes have been discussed independently in the literature, little is known about the relationship between the two. This study aims to examine the potential association between extensive social media use and the frequency of current, e-cigarette use among United States (US) youth.

Methods

Data from the 2022 National Youth Tobacco Survey (NYTS) were analyzed. The sample included 23,655 middle and high school students aged 9–18 years. Frequency of current e-cigarette use was categorized based on past-30 day use (i.e., never/former, 1–9 days, 10–29 days, or 30 days). Social media use was dichotomized into less than 4 hours daily and 4+ hours daily (i.e., extensive use). Multivariable multinomial logistic regression estimated the relationship between social media use and e-cigarette use frequency.

Results

Over one-third (35.8 %) of youth used social media extensively and 8.6 % reported current use of e-cigarettes. Extensive social media use was associated with daily e-cigarette use (OR: 1.94, 95 % CI: 1.48–2.56) but not with other use categories. Older age, female sex, lower grades, current other tobacco use, and family tobacco use were also associated with daily e-cigarette use.

Conclusions

Extensive social media use is associated with daily e-cigarette use among US youth. Public health interventions should consider the influence of social media on tobacco use behaviors and tailor prevention strategies to address this potential modifiable risk factor.

Introduction

From 2019–2021, overdose deaths among youth and young adults ages 10–19 years of age residing in the United States increased by 109 %. We sought to examine the extent to which youth and young adults who have experience with substance use are aware of the harm reduction policies and interventions, including the statewide Good Samaritan Law (GSL), naloxone, and fentanyl test strips, and have access to naloxone and fentanyl test strips.

Methods

From December 2022 to February 2023, we conducted a cross-sectional telephone survey of individuals ages 12–25 years who resided in North Carolina (NC) (N=15,000). We assessed awareness of and access to harm reduction policies and interventions among participants who reported ever using heroin/fentanyl, diverted prescription medication, cocaine, methamphetamine, and hallucinogens (n=539). Logistic regression models were used to identify factors associated with awareness of and access to these policies and interventions.

Results

We found that 81.5 % of the sample of youth and young adults who reported ever use of substances were aware of NC’s GSL, 80.0 % were aware of naloxone, 43.0 % perceived they had access to naloxone, 74.4 % were aware of fentanyl test strips, and 21.9 % perceived they had access to fentanyl test strips. There were individual and community-level characteristics associated with awareness of and perceived access to these harm reduction policies and interventions.

Conclusions

Efforts are needed to improve access to harm reduction interventions among youth and young adults as they are experiencing an increased risk of dying from opioid-involved overdoses.

Purpose

To assess trends in hospitalization for sedative misuse among youth.

Methods

Using a serial cross-sectional design, we computed hospitalization rates for sedative-related suicide attempts, sedative use disorders, and other sedative poisonings within individuals aged 5–24 years in Quebec, Canada. We computed sedative-related hospitalization rates in 2006–2011, 2012–2017, and 2018–2023, and examined differences according to age, sex, polysubstance use, mental health comorbidity, and social vulnerability using rate ratios (RR) and 95 % confidence intervals (CI) comparing the last time period relative to the first.

Results

Sedative-related hospitalization rates more than doubled during the study. Suicide attempts using sedatives increased from 50.5 per 100,000 youth in 2006–2011, to 82.2 in 2012–2017 and 114.4 in 2018–2023 (RR 2.26, 95 % CI 1.63–3.15), while sedative use disorders increased from 13.1 to 21.8 and 60.5 per 100,000 in these same time periods (RR 4.62, 95 % CI 2.54–8.40). Rates increased for 10–24 year-olds and in both sexes, particularly among youth with polysubstance use, anxiety and attention disorders, and social vulnerability.

Discussion

Sedative misuse requiring hospitalization appears to be a growing issue among youth.

Introduction

Opioid overdose mortality rates have surged dramatically in the last decade due largely to fentanyl in the illicit US drug supply. As of June 2024, 38 states, three territories, namely US Virgin Islands, Guam and the Northern Mariana Islands, and the District of Columbia, allow the medical use of cannabis products. However, there remains limited qualitative community-based evidence on the role of cannabis co-use among opioid using and injecting populations. In this study, we present data from people who inject drugs (PWID)’s co-use of cannabis-opioid.

Methods

We conducted 30 one-on-one semi-structured interviews with PWID from July 2021 to April 2022 at two community sites in Los Angeles, CA, near a syringe service program and a methadone clinic. Interviews were recorded and transcribed. We used constructivist grounded theory methods for identifying and comparing the emerging themes that appeared across transcripts to construct a conceptual explanation of how PWID co-used cannabis and opioids. Participant inclusion criteria included injection drug use, opioid and cannabis use, English fluency, and age 18+ years.

Results

PWID described that cannabis co-use assisted in developing patterns of reduced opioid use in a number of ways: 1) maintain opioid cessation and/or adhere to opioid use disorder treatment by managing cessation-specific symptoms, 2) manage symptoms of opioid withdrawal episodically and, 3) decrease opioid use due to low barrier accessibility of cannabis.

Discussion

Participants reported myriad benefits of opioid and cannabis co-use for reducing patterns of opioid use. These findings have two major harm reduction implications for PWID: 1) the distribution of cannabis via low threshold peer programming and interventions can facilitate changes in opioid use patterns and 2) access to cannabis co-use, potentially alongside existing Medication for Opioid Use Disorder, in treatment settings may improve efficacy of uptake and treatment outcomes and goals for individual PWID.

Individuals within the criminal justice system are at greater risk of substance use–related morbidity and mortality and have substantial healthcare needs. In this quasi-experimental study, we assessed utilization patterns of Massachusetts Medicaid Program (MassHealth) services and associated expenditures among drug court probationers compared to a propensity score–matched sample of traditional court probationers. Risk of reoffending, employment status, age, and living arrangement data were used to calculate propensity scores and match probationers between the two court types, producing a final sample of 271 in each court (N=542). Utilization of services and associated expenditures were analyzed using a two-part model to address the skewed distribution of the data and to control for residual differences after matching from the perspective of the payer (i.e., MassHealth). The largest categories of MassHealth spending were prescription pharmaceuticals, hospital inpatient visits, and physician visits. In the unadjusted analysis, drug court probationers exhibited greater MassHealth services utilization and expenditures than traditional court probationers. However, drug courts enrolled more females, more people at higher risk of reoffending, and more people with opioid use disorders. After controlling for differences between the two court types, the difference in MassHealth services utilization and associated expenditures did not reach statistical significance. Drug court probationers were more likely to engage with healthcare services but did not incur significantly greater expenditures than traditional court probationers after controlling for differences between the samples.

Background

Buprenorphine maintenance treatment remains unavailable in most jails in the US. We provide data on a four-day rapid sublingual buprenorphine (SL-B) induction strategy followed by a weekly dose of extended-release injectable buprenorphine (XR-B) with incarcerated individuals with opioid use disorder (OUD) ho were not opioid tolerant.

Methods

Between October 2020 to April 2024, N = 65 individuals with an opioid use disorder in jails participating in a larger randomized, controlled trial received SL-B and XR-B prior to release. Primary outcomes included completing the proposed dose induction and any reported adverse events (AEs).

Results

Sixty-five individuals received SL-B dose induction from our team’s medical staff, 53 (81.5 %) completed the four-day SL-B dose induction and received their first weekly XR‑B injection on day 5. Of the 65 individuals, 10 (15.38 %) participants reported AEs during the dosing period and/or in the week following the dosing period. All but one of the AE’s were rated as mild. One participant experienced a serious adverse event in the week following dose induction. The study medical team determined that this was unlikely to be related to the intervention.

Discussion

Overall, our study findings demonstrate the feasibility of implementing a four-day sublingual dose induction followed by a weekly XR-B injection with incarcerated individuals who are not opioid tolerant. This study provides important data to illustrate a dose induction strategy that might assist in reducing illicit diversion in jails, which is a main barrier to buprenorphine delivery cited by correctional administrators.

Background

A growing evidence base supports the value of peer recovery support specialists (PRSS), particularly due to shared lived experience with participants (recipients of PRSS services). However, little research has examined whether congruence on certain aspects of “peerness” (e.g., demographics, experiences) matters for PRSS-participant relationships.

Methods

Through a pilot study under the NIDA-funded Initiative for Justice and Emerging Adult Populations (JEAP), adults who had recently received PRSS services (N=100) were interviewed. Participants completed a modified version of the Scales for Participant Alliance with Recovery Coach (SPARC), a measure of PRSS-participant relationship quality, and rated themselves as different/similar to their PRSS in several domains using a six-point scale.

Results

Participants had met with their PRSS for a median of 10 sessions over two months. SPARC scores were unrelated to participant demographics or lived experiences. However, better-quality relationships were reported by participants who believed their PRSS was similar to them in relationships with family (p=.004), spirituality/religion (p=.001), age (p<.001), and overall recovery pathway (p<.001). Total SPARC scores were not significantly correlated with perceived PRSS-participant similarities on gender, race/ethnicity, substances of choice, and history of incarceration or substance use treatment.

Discussion

Results from this pilot study suggest that PRSS-participant alignment on past experiences (e.g., prior incarceration, choice of drugs) may not be needed to establish good-quality working relationships. However, similarities on factors related to current life stage (e.g., age, family relationships) and/or recovery process (e.g., overall pathway, spirituality) may be more important. Future research should employ mixed-methods approaches to elucidate these unique findings.

Expanding Medicaid plays a large role in ensuring that people across the United States have access to health care services. Although North Carolina recently moved toward Medicaid expansion, the impact of expansion on overdoses and overdose mortality may vary based on the type of treatment (offering medications for opioid use disorder [MOUD] vs. offering inpatient medically managed withdrawal without linkage to further MOUD treatment or non–MOUD-based treatment) accessed by individuals newly eligible for treatment through expansion. Based on official North Carolina statistics and published peer-reviewed literature, we developed a simulation model that forecasts opioid overdose and mortality under different scenarios for type of treatment accessed (MOUD-based vs. non–MOUD-based) and Medicaid coverage levels. An optimistic scenario assuming 70 % of individuals newly eligible for treatment would enter treatment during the first year of expansion estimated that 332 (Simulation Interval: 246–412) overdose deaths would be averted. A scenario more in line with recent historical trends assuming 38 % of individuals newly eligible for treatment would enter treatment resulted in 213 (Simulation Interval: 157–263) averted overdose deaths. In all scenarios, MOUD-based treatment approaches increased the number of lives saved compared with approaches expanding opioid treatment through non–MOUD-based treatment. Our study emphasized the need to ensure access to MOUD-based treatment for individuals newly covered by the Medicaid expansion.

Background

The prevalence of cannabis use disorder (CUD) is increasing in the US and primary care providers need tools to identify patients with moderate-severe CUD to facilitate treatment. A single-item screen for cannabis (SIS-C) has outstanding discriminative validity for CUD. However, because the prevalence of moderate-severe CUD is typically low, the probability that an average patient who screens positive for daily cannabis has moderate-severe cannabis use disorder is low, making follow-up assessment important.

Methods

This study reports the discriminative validity of a DSM-5 Substance Use Symptom Checklist (“Checklist”) for moderate-severe CUD among 498 primary care patients who reported daily cannabis use on the SIS-C. We evaluated the performance of the Checklist (score 0–11) completed during routine care, compared to ≥4 DSM-5 CUD symptoms (moderate-severe CUD) on the Composite International Diagnostic Interview Substance Abuse Module from a confidential survey (reference standard). We estimated areas under receiver operating curve (AUROC), sensitivities, specificities, and post-test probabilities.

Results

Of 498 eligible patients, 17 % met diagnostic criteria for moderate-severe CUD. The Checklist’s AUROC for moderate-severe CUD was 0.77 (95 % CI: 0.71–0.83), and Checklist scores of 1–2 balanced sensitivity and specificity. Among patients from a population with average prevalence of CUD before screening (~6 % prevalence) and daily use on the SIS-C, a Checklist score of 3 indicated a post-test probability of 82.1 %.

Conclusion

Overall performance of the Checklist was good and the high specificity made it useful for identifying patients likely to have moderate-severe CUD among those at average risk.
