Opiates are substances derived from the opium plant or similar synthetics that are used medicinally as painkillers but also have high potential for abuse. While opiates are useful for medical purposes like pain relief after surgery, recreational use and addiction can lead to dependence and negative health effects. Long-term opiate abuse increases risks of overdose, disease transmission from shared needles, and weakening of the immune system. Though opiates have a long history of medical usage, problems arose when their potency increased without understanding of dangers, leading to widespread abuse and addiction issues today.
