Abstract
Social buffering is the phenomenon in which the presence of an affiliative conspecific mitigates stress responses. We previously demonstrated that social buffering completely ameliorates conditioned fear responses in rats. However, the neuromodulators involved in social buffering are poorly understood. Given that opioids, dopamine, oxytocin and vasopressin play an important role in affiliative behaviour, here, we assessed the effects of the most well-known antagonists, naloxone (opioid receptor antagonist), haloperidol (dopamine D2 receptor antagonist), atosiban (oxytocin receptor antagonist) and SR49059 (vasopressin V1a receptor antagonist), on social buffering. In Experiment 1, fear-conditioned male subjects were intraperitoneally administered one of the four antagonists 25 min prior to exposure to a conditioned stimulus with an unfamiliar non-conditioned rat. Naloxone, but not the other three antagonists, increased freezing and decreased walking and investigation as compared with saline administration. In Experiment 2, identical naloxone administration did not affect locomotor activity, anxiety-like behaviour or freezing in an open-field test. In Experiment 3, after confirming that the same naloxone administration again increased conditioned fear responses, as done in Experiment 1, we measured Fos expression in 16 brain regions. Compared with saline, naloxone increased Fos expression in the paraventricular nucleus of the hypothalamus and decreased Fos expression in the nucleus accumbens shell, anterior cingulate cortex and insular cortex and tended to decrease Fos expression in the nucleus accumbens core. Based on these results, we suggest that naloxone blocks social buffering of conditioned fear responses in male rats.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 123:104253. [PMID: 37995551 DOI: 10.1016/j.drugpo.2023.104253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 10/29/2023] [Accepted: 10/30/2023] [Indexed: 11/25/2023]
Abstract
Naloxone is a medication used to reverse opioid overdose. Alongside its lifesaving effects, it also has a reputation for producing distress, aggression and occasionally violence upon administration. This article analyses how take-home naloxone (THN) training initiatives address naloxone's reputation for producing aggression and conflict, and how new subject positions emerge in the context of this training. While the role of naloxone in producing aggression has been discussed in a range of research, this work emphasises that such conflict is neither inevitable nor even likely because it is contingent on several other issues such as administration practices. Building on this scholarship, we work with Bruno Latour's theorisation of technological 'affordances' to analyse THN as a socially co-produced technology that, rather than either determining or neutrally communicating actions and effects, 'affords' possibilities, capacities and subjects. Analysing data drawn from observations of THN training in Victoria, Australia, and in-depth interviews with training participants, we argue that the issue of conflict upon revival affords a subject position we term the 'angry Narcanned subject'. This subject, we note, has come to hold a powerful position in understandings of naloxone, not least because it tends to accord with stereotypes of antisocial drug users. From here, we argue that a much of THN training is focused on challenging and reframing naloxone's reputation for conflict and questioning related subject positions, especially that of the angry Narcanned subject. We argue that this process of challenging and reframing affords two new subject positions for consumers: the 'capable administrator' and the 'calmer revivee'. We conclude that while THN training affords multiple, potentially positive, subject positions, unless these initiatives are accompanied by broader interventions such as decriminalisation campaigns, they may inadvertently responsibilise people who consume opioids for addressing overdose and erase the role of prohibition, criminalisation and stigmatisation in producing overdose events.

Take-Home Naloxone and risk management from the perspective of people who survived an opioid overdose in Stockholm - An analysis informed by drug, set and setting. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 115:104021. [PMID: 37011507 DOI: 10.1016/j.drugpo.2023.104021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 03/24/2023] [Accepted: 03/27/2023] [Indexed: 04/05/2023]
Abstract
BACKGROUND Take-Home Naloxone (THN) programs were introduced in Sweden in 2018 - a country with one of the highest rates of overdose mortality in the EU and a severe stigmatisation of people who inject drugs. This qualitative study builds on the international research that has expanded a previously narrow and medical focus on overdose deaths. It uses Zinberg's framework to look beyond the role of the "drug" to include the attitudes and personality of the person ("set") and contextual factors ("setting"). This study explores the impacts of THN from the perspective of overdose survivors. METHODS Between November 2021 and May 2022 semi-structured interviews were conducted with 22 opioid overdose survivors, recruited among clients of the Stockholm needle and syringe program. All the participants had been treated with naloxone in an overdose situation. The interviews were processed through thematic analysis using deductive and inductive coding in accordance with the theoretical framework. RESULTS Interviewees included men and women who used different types of drugs. THN has impacted on "drug" in terms of naloxone-induced withdrawal symptoms and peers having to deal with survivors' emotions. Exploring "set" revealed feelings of shame following naloxone revival for the person who overdosed. Despite such reactions, participants retained an overwhelmingly positive attitude towards THN. Participants integrated THN into their risk management practices ("setting") and some acknowledged that THN provided a new way to treat overdoses without necessarily needing to interact with authorities, especially the police. CONCLUSION The THN program has influenced "drug, set and setting" for participants, providing increased safety at drug-intake and transferring overdose management and the burden of care to the community. The lived experience of participants also exposes the limitations of THN indicating that there are additional unmet needs beyond THN programs, particularly in terms of "setting".

Abstract
BACKGROUND Opioid overdose rates have steadily been increasing in the United States (US) creating what is considered an overdose death crisis. The US has a mixture of public health and punitive policies aimed to address opioid use and the overdose crisis, yet little is known about public opinion relating to opioid use and policy support. Understanding the intersection of public opinion about opioid use disorder (OUD) and policy can be useful for developing interventions to address policy responses to overdose deaths. METHODS A national sample of cross-sectional data from the AmeriSpeak survey conducted from 27 February 2020 through 2 March 2020 was analyzed. Measures included attitudes toward OUD and policy beliefs. Latent class analysis, a person-centered approach, was used to identify groups of individuals endorsing similar stigma and policy beliefs. We then examined the relationship between the identified groups (i.e., classes) and key behavioral and demographic factors. RESULTS We identified three distinct groups: (1) "High Stigma/High Punitive Policy", (2) "High Stigma/Mixed Public Health and Punitive Policy", and (3) "Low Stigma/High Public Health Policy". People with higher levels of education had reduced odds of being in the "High Stigma/High Punitive Policy" group. CONCLUSION Public health policies are most effective in addressing OUD. We suggest targeting interventions toward the "High Stigma/Mixed Public Health and Punitive Policy" group since this group already displays some support for public health policies. Broader interventions, such as eliminating stigmatizing messaging in the media and redacting punitive policies, could reduce OUD stigma among all groups.

Assessment of Neurotoxic Effects of Oxycodone and Naloxone in SH-SY5Y Cell Line. Int J Mol Sci 2023; 24:ijms24021424.

Abstract
Opioid drugs have analgesic properties used to treat chronic and post-surgical pain due to descending pain modulation. The use of opioids is often associated with adverse effects or clinical issues. This study aimed to evaluate the toxicity of opioids by exposing the neuroblastoma cell line (SH-SY5Y) to 0, 1, 10, and 100 µM oxycodone and naloxone for 24 h. Analyses were carried out to evaluate cell cytotoxicity, identification of cell death, DNA damage, superoxide dismutase (SOD), glutathione S-transferase (GST), and acetylcholinesterase (AChE) activities, in addition to molecular docking. Oxycodone and naloxone exposure did not alter the SH-SY5Y cell viability. The exposure to 100 µM oxycodone and naloxone significantly increased the cells' DNA damage score compared to the control group. Naloxone exposure significantly inhibited AChE, GST, and SOD activities, while oxycodone did not alter these enzymes' activities. Molecular docking showed that naloxone and oxycodone interact with different amino acids in the studied enzymes, which may explain the differences in enzymatic inhibition. Naloxone altered the antioxidant defenses of SH-SY5Y cells, which may have caused DNA damage 24 h after the exposure. On the other hand, more studies are necessary to explain how oxycodone causes DNA damage.

Abstract
BACKGROUND AND AIMS This qualitative study aimed to explore how the development of tolerance to both the psychoactive and respiratory depressant effects of heroin on re-exposure are experienced by people who use heroin. METHODS Semi-structured one-to-one interviews were conducted with 20 adults who currently or previously used heroin (for at least 6 months), with any type of administration (injected, smoked) and experience of abstinence (at least 2 weeks) and relapse. Topic guides explored the participants understanding of tolerance, their experience of developing tolerance to heroin and of tolerance following relapse. Interviews were audio-recorded and transcribed. Thematic analysis was used to generate salient themes. RESULTS The analysis produced three broad themes: lay understanding of tolerance; tolerating tolerance; and rapid tolerance development following relapse. Tolerance was defined as the body adapting to regular drug use, so that the drug no longer produced the same level of effect. Tolerance was experienced as interacting and co-developing with physical dependence and the symptoms of withdrawal. Indeed, several participants did not differentiate between tolerance and dependence. Most participants did not notice tolerance to respiratory depression. Tolerance levels fluctuated-increasing over periods of regular use and reducing when abstinent. Using more drug was the most common response to increasing tolerance to the desired effects. On re-use following abstinence, tolerance was experienced as developing more quickly in the most recent relapse compared to the first. Tolerance was also perceived to return more quickly with each abstinence-relapse cycle. CONCLUSIONS Qualitative accounts of tolerance report that tolerance returns more quickly with each relapse episode. By elucidating the mechanism(s) involved and potentially discovering how they could be switched on prior to relapse occurring we might be able to develop a beneficial harm reduction treatment for people in abstinence that would protect against overdose occurring on subsequent relapse.

Abstract
Overdose prevention for people who use illicit drugs is essential during the current overdose crisis. Peer support is a process whereby individuals with lived or living experience of a particular phenomenon provide support to others by explicitly drawing on these experiences. This review provides a systematic search and evidence synthesis of peer support within overdose prevention interventions for people who use illicit drugs. A systematic search of six databases (CINAHL, SocINDEX, PsycINFO, MEDLINE, Scopus, and Web of Knowledge) was conducted in November 2020 for papers published in English between 2000 and 2020. Following screening and full-text review, 46 papers met criteria and were included in this review. A thematic analysis approach was used to synthesize themes. Important findings include: the value of peers in creating trusted services; the diversity of peers' roles; the implications of barriers on peer-involved overdose prevention interventions; and the stress and trauma experienced by peers. Peers play a pivotal role in overdose prevention interventions for people who use illicit drugs and are essential to the acceptability and feasibility of such services. However, peers face considerable challenges within their roles, including trauma and burnout. Future interventions must consider how to support and strengthen peer roles in overdose settings.

Abstract
Background: Our aim was to explore emotional reactions to intervening in an overdose event from the perspective of individuals who use opioids (peer responders). In addition, we were interested in the impact this experience may have on peer responders' feelings about helping in an overdose situation in the future. Methods: For this qualitative sub-study of a randomized controlled trial (RCT), data from 61 interviews were analyzed thematically using an inductive approach. Results: Peer responders had diverse emotional reactions to the overdose event. These ranged from a sense of pride and other positive feelings associated with their ability to help to ambivalence about being involved in situations perceived as challenging and burdensome. There were few reports of the overdose event as an exclusively negative experience. Many peer responders perceived it as their duty to use naloxone again if required. However, some had ambivalent feelings toward this responsibility, which may be related to negative experiences with previous intervention efforts. Conclusions: The capacity of people who use opioids to help reduce the harms associated with opioid overdose is experienced as empowering by some. Nonetheless, engaging peer responders in strategies to reduce opioid-related mortality should be coupled with appropriate resources to process their experiences and emotional responses.

Abstract
BACKGROUND Targeted naloxone distribution to potential lay responders increases the timeliness of overdose response and reduces mortality. Little is known, however, about the patterns of decision-making among overdose lay responders. This study explored heuristic decision-making among laypersons equipped with an emergency response smartphone app. METHODS UnityPhilly, a smartphone app that connects lay responders equipped with naloxone to overdose victims, was piloted in Philadelphia from March 2019 to February 2020. Participants used the app to signal overdose alerts to peer app users and emergency medical services, or respond to alerts by arriving at overdose emergency sites. This study utilised in-depth interviews, background information, and app use data from a sample of 18 participants with varying histories of opioid use and levels of app use activity. RESULTS The sample included 8 people who used opioids non-medically in the past 30 days and 10 people reporting no opioid misuse. Three prevailing, not mutually exclusive, heuristics were identified. The heuristic of unconditional signalling ("Always signal for help or backup") was used by 7 people who valued external assistance and used the app as a replacement for a 911 call; this group had the highest number of signalled alerts and on-scene appearances. Nine people, who expressed confidence in their ability to address an overdose themselves, followed a heuristic of conditional signalling ("Rescue, but only signal if necessary"); these participants had the highest frequency of prior naloxone administrations. Eleven participants used the heuristic of conditional responding ("Assess if I can make a difference"), addressing an alert if they carried naloxone, were nearby, or received a signal before dark hours. CONCLUSION The deployment of specific heuristics was influenced by prior naloxone use and situational factors. Success of overdose prevention interventions assisted by digital technologies may depend on the involvement of people with diverse overdose rescue backgrounds.

Abstract
BACKGROUND Take-home naloxone (THN) kits have been designed to provide community members (including people who use drugs, their families and/or significant others) with the necessary resources to address out-of-hospital opioid overdose events. Kits typically include two doses of naloxone. This 'twin-pack' format means that lay responders need information on how to use each dose. Advice given tends to be based on dosage algorithms used by medical personnel. However, little is currently known about how and why people who use drugs, acting as lay responders, decide to administer the second dose contained within single THN kits. The aim of this article is to explore this issue. METHODS Data were generated from a qualitative semi-structured interview study that was embedded within a randomised controlled trial examining the risks and benefits of Overdose Education and Naloxone Distribution (OEND) training in New York City (NYC). Analysis for this article focuses upon the experiences of 22 people who use(d) opioids and who provided repeat naloxone administrations (RNA) during 24 separate overdose events. The framework method of analysis was used to compare the time participants believed had passed between each naloxone dose administered ('subjective response interval') with the 'recommended response interval' (2-4 minutes) given during OEND training. Framework analysis also charted the various reasons and rationale for providing RNA during overdose interventions. RESULTS When participants' subjective response intervals were compared with the recommended response interval for naloxone dosing, three different time periods were reported for the 24 overdose events: i. 'two doses administered in under 2 minutes' (n = 10); ii. 'two doses administered within 2-4 minutes' (n = 7), and iii. 'two doses administered more than 4 minutes apart' (n = 7). A variety of reasons were identified for providing RNA within each of the three categories of response interval. Collectively, reasons for RNA included panic, recognition of urgency, delays in retrieving naloxone kit, perceptions of recipients' responsiveness/non-responsiveness to naloxone, and avoidance of Emergency Response Teams (ERT). CONCLUSION Findings suggest that decision-making processes by people who use opioids regarding how and when to provide RNA are influenced by factors that relate to the emergency event. In addition, the majority of RNA (17/24) occurred outside of the recommended response interval taught during OEND training. These findings are discussed in terms of evidence-based intervention and 'evidence-making intervention' with suggestions for how RNA guidance may be developed and included within future/existing models of OEND training.

Factors associated with withdrawal symptoms and anger among people resuscitated from an opioid overdose by take-home naloxone: Exploratory mixed methods analysis. J Subst Abuse Treat 2020; 117:108099. [PMID: 32811629 DOI: 10.1016/j.jsat.2020.108099] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2020] [Revised: 07/06/2020] [Accepted: 07/25/2020] [Indexed: 01/04/2023]
Abstract
INTRODUCTION Take-home naloxone (THN) is a clinically effective and cost-effective means of reducing opioid overdose fatality. Nonetheless, naloxone administration that successfully saves a person's life can still produce undesirable and harmful effects. AIM To better understand factors associated with two widely reported adverse outcomes following naloxone administration; namely the person resuscitated displays: i. withdrawal symptoms and ii. anger. METHODS A mixed methods study combining a randomized controlled trial of overdose education and naloxone prescribing to people with opioid use disorder and semi-structured qualitative interviews with trial participants who had responded to an overdose whilst in the trial. All data were collected in New York City (2014-2019). A dataset (comprising demographic, pharmacological, situational, interpersonal, and overdose training related variables) was generated by transforming qualitative interview data from 47 overdose events into dichotomous variables and then combining these with quantitative demographic and overdose training related data from the main trial. Associations between variables within the dataset and reports of: i. withdrawal symptoms and ii. anger were explored using chi-squared tests, t-tests, and logistic regressions. RESULTS A multivariate logistic regression found that people who had overdosed were significantly more likely to display anger if the person resuscitating them criticized, berated or chastised them during resuscitation (adjusted OR = 27 [95% CI = 4.0-295]). In contrast, they were significantly less likely to display anger if the person resuscitating them communicated positively with them (OR = 0.10 [95% CI = 0.01-0.78]). Both positive and negative communication styles were independently associated with anger, and communication was associated with 59% of the variance in anger. There was no evidence that people who displayed withdrawal symptoms were more likely to display anger than those not displaying withdrawal symptoms, and neither displaying withdrawal symptoms nor displaying anger were associated with using more drugs after resuscitation. CONCLUSIONS Contrary to common assumptions, withdrawal symptoms and anger following naloxone administration may be unrelated phenomena. Findings are consistent with previous research that has suggested that a lay responder's positive or reassuring communication style may lessen anger post overdose. Implications for improving THN programmes and naloxone administration are discussed.

Jones JD, Campbell AN, Brandt L, Castillo F, Abbott R, Comer SD. Intervention in an opioid overdose event increases interest in treatment among individuals with opioid use disorder. Subst Abus 2020; 42:407-411. [PMID: 32814002 DOI: 10.1080/08897077.2020.1809607] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/06/2023]
Abstract
BACKGROUND This study sought to explore whether intervening in suspected cases of opioid overdose alters interest in treatment for opioid use disorder (OUD). Data were collected as a part of a trial comparing the effects of different overdose education and naloxone distribution (OEND) training curricula on overdose outcomes. Methods: Following OEND training, participants completed four in-person follow-up visits at 1-, 3-, 6- and 12-months. Participants were also regularly contacted to inquire about overdose events they responded to, witnessed, or experienced themselves. Other assessments included the Addiction Severity Index that queries participants' perceived importance of drug treatment on a scale of: 0 (Not at All) to 4 (Extremely). For the current secondary data analysis, treatment importance was assessed at the time points most immediately preceding and following participant intervention in an overdose event using naloxone. Results: The sample reported a mean duration of opioid use of 14.9 (± 11.5) years, with 67% having witnessed an overdose event prior to the study. Of the 321 enrolled, 92 participants used naloxone in response to 166 suspected cases of an opioid overdose. For the entire sample, mean treatment importance did not significantly change throughout the study. Among participants who utilized naloxone, treatment importance increased following the event (Before: 3.03, After: 3.39, p = 0.02). Due to the amount of time between the overdose event and assessment of post-event treatment importance (40.5 days, ±40.2), the current study most likely underestimates this effect. Conclusions: The current study suggests that responding to an overdose event increases interest in OUD treatment. Currently only considered an acute intervention to reduce overdose morbidity and mortality, OEND may have the potential to increase enrollment in medications to treat OUD. However, a prospective investigation needs to determine if the impact of an overdose event could be utilized to increase treatment engagement.
