In the short term, opioids can relieve pain and make people feel relaxed and happy. However, opioids can also have harmful effects, including:
- Slowed breathing
Opioid misuse can cause slowed breathing, which can cause hypoxia, a condition that results when too little oxygen reaches the brain. Hypoxia can have short- and long-term psychological and neurological effects, including coma, permanent brain damage, or death. Researchers are also investigating the long-term effects of opioid addiction on the brain, including whether damage can be reversed.
