People addicted to any substance are more likely to contract COVID-19. They are also more likely to be hospitalized or die. The new study, from the National Institute on Drug Abuse, funded by the National Institutes of Health, found that people addicted to tobacco or opioids were most likely among those with substance use disorders to develop COVID-19. As for why, it seems that addicted people are more likely to have health conditions that increase their risk for the virus, like hypertension and obesity. Plus, they are more likely to face more socioeconomic risks, like being homeless and using public transportation.
