What infective risks are associated with opioid abuse?

The association between opioid abuse and certain infective risks is well-documented, primarily due to the behaviors and practices that often accompany substance use. When individuals misuse opioids, particularly through injection, there are significant risks of blood-borne infections, including HIV and Hepatitis C.

HIV (Human Immunodeficiency Virus) is transmitted through the exchange of bodily fluids, and sharing needles or other injection equipment greatly increases this risk among people who inject drugs. Similarly, Hepatitis C, which poses a serious threat to liver health, is also primarily spread through blood contact, and rates of infection rise steeply in populations where injection drug use is prevalent.

Infective endocarditis, a serious infection of the heart lining, can occur when bacteria enter the bloodstream, which can happen through injection techniques or poor hygiene practices associated with drug use. Individuals who inject opioids are at increased risk of this condition due to both the potential introduction of infectious agents through the skin and the likelihood of pre-existing heart conditions in users.

Other options do not align as closely with the specific risks linked to opioid abuse. For instance, while influenza, tuberculosis, and pneumonia are respiratory infections (often linked to general health and immune status), they are not directly associated with the
