Brief reportOverdosing among young injection drug users in San Francisco
Introduction
In the 1990s, the street price of heroin in the US decreased while the purity increased National Narcotics Intelligence Consumers Committee (NNICC), 1997, Office of National Drug Control Policy, 1997. The accessibility of heroin and the number of young injection drug users (IDUs) in the US are thought to have increased correspondingly (Office of National Drug Control Policy, 1998). Heroin-related emergency department (ED) visits increased 99% from 1988 to 1995, with more than a third of the visits involving an overdose (National Institute of Drug Abuse, 1995). A 241% increase in heroin/morphine ED episodes occurred in young people from 1995 to 1997 (OAS, 1999).
San Francisco, with 314 admissions per 100,000 people per year, has the highest heroin-related hospitalization rate in the US (Public Statistics Institute, 1997). Drug overdoses in San Francisco account for 31% of preventable deaths and are the leading cause of injury death in the city (San Francisco Department of Public Health and Injury Prevention Center, 1996). In California as a whole, heroin overdose deaths have risen 52% in the last 5 years (Public Statistics Institute, 1997).
Along with the increase in overdoses, the 1990s have seen the rise of harm reduction approaches in public health. In practice, however, harm reduction programs for injectors have usually focused on reducing morbidity and mortality due to HIV. Overdose mortality, though high, has remained a largely unexplored problem in the US. In other countries, overdosing has been identified as the leading cause of death among heroin users, exceeding AIDS Darke et al., 1996, Darke & Zador, 1996, Gossop et al., 1996.
Young IDUs are probably at higher risk of overdose than older injectors (Frischer, Goldberg, et al., 1997) and engage in more high-risk behaviors for HIV infection than older injectors (Fennema, Van Ameijden, et al., 1997). However, no US studies have yet examined overdosing in this population. We report a study of overdosing among young IDUs in San Francisco.

Methods
In September–November 1996, we used “peer-access” interviewers, i.e. young persons who were familiar with drug use and the street scene, to contact and interview persons in San Francisco aged 14–29 who had injected drugs in the previous 6 months. Interviewers were recruited from service organizations for street youth and were trained by us in interviewing techniques.
Study subjects were recruited and interviewed at six needle exchanges and three youth outreach sites. The needle exchanges were
Results
A total of 124 young IDUs were recruited. Most were white (73%) and male (70%) (Table 1). Almost half the subjects reported living on the street, and only 15% had a home, apartment, or room of their own. The median age of subjects was 22, and the median number of years injecting was 4. The majority of subjects had not completed a high school education. Thirty-seven percent reported gay or bisexual behavior.
The drug which the highest proportion of subjects reported injecting in the last 30 days
Discussion
Overdosing is strikingly common among young IDUs. With a median age of 22, after a median of 4 years of injecting, 48% of young injectors in our study had experienced an overdose. Those who had overdosed reported a median of 0.5 overdoses per year of injecting.
A history of overdosing was associated with speedball injection in the prior month, with the borrowing and lending of syringes, and (with P-values of borderline statistical significance) with heroin injection and with gay or bisexual

Opioid agonist therapy trajectories among street entrenched youth in the context of a public health crisis
2020, SSM - Population HealthCitation Excerpt :Youth ages 15 to 24 represent the fastest growing age demographic for hospitalizations due to opioid poisoning in Canada (BC Coroners Service, 2020; Canadian Institute for Health Information, 2016), while in BC, more than 1000 youth ages 10 to 29 have lost their lives to overdose since an official public health emergency was declared in 2016 (BC Coroners Service, 2020; Government of Canada, 2018). Youth who use drugs in the context of street entrenchment (i.e., those experiencing homelessness or without stable housing, frequently in the context of other kinds of overlapping exclusion along axes of race, class, sexual orientation and gender identity) are particularly vulnerable to fatal and non-fatal overdose and a myriad of other harms (Hadland et al., 2014; Kerr et al., 2009; Lyons, Yule, Schiff, Bagley, & Wilens, 2019; Mitra, Wood, Nguyen, Kerr, & DeBeck, 2015; Ochoa, Hahn, Seal, & Moss, 2001; Werb, Kerr, Li, Montaner, & Wood, 2008). Opioid agonist therapy (OAT) is a cornerstone of the public health response to the overdose crisis.

2016, Drug and Alcohol DependenceCitation Excerpt :Substantially more common than fatal overdose (Warner-Smith et al., 2002), non-fatal overdoses are the cause of significant morbidity with a proportion of individuals suffering from hypoxia, aspiration or other negative health outcomes (Britton et al., 2010; Warner-Smith et al., 2002, 2001). The reported prevalence of non-fatal overdoses among illicit drug users has varied significantly based on geography and study population, with estimates ranging between 20% and 70% per lifetime (Darke et al., 1996; Kerr et al., 2007; Kinner et al., 2012; Ochoa et al., 2001; Silva et al., 2013). One important question, which remains insufficiently addressed in the literature, is to what degree non-fatal overdose events are associated with the risk of subsequent fatal overdose.
Correlates of overdose risk perception among illicit opioid users
2016, Drug and Alcohol DependenceCitation Excerpt :Educational components of behavioral interventions may benefit from emphasizing overdose risk associated with opioid analgesics despite the greater knowledge of the dosage and contents and overall perceived safety of prescription drugs compared to illicit substances; indeed, wide variation in the potency of opioid analgesics make understanding strength and dosage extremely important to their safe use (Svendsen et al., 2011; Von Korff et al., 2008). Our finding in regards to age, namely that age is inversely associated with high risk perception, is in accordance with several studies that have identified younger age as an independent risk factor for opioid overdose among people who inject drugs (PWID; Coffin et al., 2007; Kinner et al., 2012; Ochoa et al., 2005, 2001; Seal et al., 2001; Sherman et al., 2007). Although younger opioid users experience higher rates of overdose, those who are older are more likely to die from overdose (Pierce et al., 2015).
The role of social networks and geography on risky injection behaviors of young persons who inject drugs
2015, Drug and Alcohol DependenceCitation Excerpt :Our study of young PWID from both urban and suburban areas of a large metropolitan city reports novel data on the behavioral and geographic characteristics of this population and their injection networks. As in prior studies (Armstrong, 2007; Broz and Ouellet, 2008; Broz et al., 2014; Garfein et al., 1998; Hahn et al., 2010; Neaigus et al., 2006; Ochoa et al., 2001; Prussing et al., 2014; Pugatch et al., 2006), our study showed that young PWID are likely to be non-Hispanic white (71%), even though our recruitment sites were located in urban, predominantly African American and Hispanic neighborhoods. A main finding of our study is that homelessness and residential transience are integral components of HCV and HIV risk, mediated through network size and syringe sharing.
