(Portland, OR) -- People recently released from prisons in Oregon face a risk for opioid overdose ten times greater than the general public. Researchers at OSU, OHSU and PSU studied inmates who were paroled and found the risk of overdose was highest in the first two weeks after release. The risk was highest among women and people with mental health or substances abuse disorder treatment needs. They say the study shows it's important to develop ways to help reduce the risk including providing Narcan which can help reverse the effects of an overdose.
