New research from Boston Medical Center found that substance use disorders do not increase the likelihood of dying from COVID-19. Published in Substance Abuse: Research and Treatment, the study showed that the increased risk for severe COVID-19 in people with SUD that has been seen may be the result of co-occurring medical conditions.
