Opioid dependence is a medical condition characterized by a strong craving for opioids, which are powerful pain-relieving medications. This condition can develop after prolonged use of prescription opioids, such as morphine or oxycodone, or from illicit drugs like heroin. Individuals may find it difficult to stop using these substances despite negative consequences on their health and daily life. Symptoms of opioid dependence include increased tolerance, withdrawal symptoms when not using, and continued use despite problems. Treatment options often involve a combination of medication-assisted treatment and counseling to help individuals manage their dependence and reduce the risk of relapse.
