The use of which drug is most commonly linked to heroin abuse?

The most commonly linked drug to heroin abuse is prescription opioids due to the way they affect the brain and body. Prescription opioids, such as oxycodone, hydrocodone, and morphine, share a similar pharmacological profile with heroin. They are both classified as opioids and act on the same receptors in the brain, producing euphoria and pain relief.

Individuals who initially use prescription opioids for legitimate medical reasons may develop tolerance and dependence, leading them to seek stronger substances when their prescription runs out or becomes unavailable. This often leads to the abuse of heroin, which is typically cheaper and more accessible on the street.

Understanding this relationship is crucial for recognizing patterns of substance abuse and developing effective interventions for individuals struggling with opioid use disorder. This connection has important implications for public health, especially given the opioid epidemic, where the transition from prescription opioid misuse to heroin use is a significant concern.
