The effects of opioids occur as the substance stimulates the natural opioid receptors in the brain.
There are several forms of opioids, including:
- Prescription opioid painkillers like Vicodin (hydrocodone) and OxyContin (oxycodone)
- Fentanyl and other synthetic opioids
When you ingest opioids, this reduces the amount of pain signals transmitted in your system, leading to an altered perception of pain. In addition to these primary pain-relieving qualities, opioids also cause feelings of euphoria.
