Opioid addiction refers to a condition where an individual becomes physically and/or psychologically dependent on opioids, which are drugs derived from the poppy plant. Opioids include prescription painkillers such as morphine, oxycodone, and hydrocodone, as well as illicit substances like heroin. When a person becomes addicted to opioids, they experience intense cravings for the drug, lose control over their use, and continue using despite negative consequences in their life. Opioid addiction can lead to significant health problems, social and legal issues, and can be difficult to treat, requiring professional help and support.
