Opioid addiction is a condition in which a person becomes physically and psychologically dependent on opioids, which are highly addictive pain relievers. Opioids can lead to changes in brain chemistry and the development of dependence, and can also increase the risk of overdose and death. Treatment options for opioid addiction may include medication-assisted treatment, behavioral therapies, and support groups. Prevention strategies include avoiding opioid use altogether, seeking non-opioid pain management alternatives, and safe disposal of unused medications. The opioid epidemic has become a major public health crisis, and addressing opioid addiction and misuse remains a critical priority in healthcare.
