Background
Injection drug use initiation represents a critical point of public health intervention, as injection increases risk forblood borne infections including Hepatitis C and HIV. In this paper, weexplore pathways to injection initiation among youth (<=30) in the ruralcontext of California’s Central Valley, where rates of injection drug useare among the highest in the nation.
Methods
We draw on semi-structured qualitative interviews with 20 younginjectors to examine drug use histories, including the factors that participants associated with their transition to injection drug use.
Results
The average age was 24.7 years (range: 20–30), 45% were female(n=9), and 30% were Latino (n=6). Participants described a variety ofpathways to injection, culminating in a first injection that involvedeither opioids (n=12) or methamphetamine (n=8). Among the opioid group, the majority used prescription opioids before transitioning to injection, while a smaller number transitioned to opioid injection from non-opioid recreational drug use. Injectors who first used prescription opioidsoften described growing up in affluent suburban areas and transitioned toinjection with peers, owing to a combination of factors related toindividual tolerance, cost, and shifting drug markets. In contrast, methamphetamine initiates grew up in less affluent families withhistories of substance use that exposed them to drugs at an early age. Methamphetamine users transitioned from smoking and snorting toinjection, often with family members or intimate partners, within broadercontexts of social disadvantage and stress.
Conclusions
While much of the focus on young injectors has centered onthe current opioid epidemic, our data suggest a need to consider multiple pathways toward injection initiation of different drugs. Targetedinterventions addressing the unique injection transition contexts of bothopioids and methamphetamine are urgently needed in the Central Valley ofCalifornia.
