Opioids are powerful pain relievers that include drugs like codeine, oxycodone, morphine, and heroin. While opioids are used medically to treat pain, dependence and addiction can develop with prolonged use. Withdrawal symptoms like rapid breathing, sweating, and diarrhea appear when use stops. Prolonged opioid use can also lead to complications like lung damage, infections from unsterilized needles, and neurological issues. Babies born to mothers using opioids may experience withdrawal. Treatment options include medication to block opioid effects and long-term therapeutic communities.
