(Elsevier) A genome-wide association study has identified a new genetic alteration in European-Americans with opioid dependence. The study, published in Biological Psychiatry, included over 3,000 opioid-exposed people. The new findings provide insight into the biological origins of opioid dependence, which has become an epidemic of historical proportions in the US, driven by dangerous use of prescription painkillers and heroin.
