COVID-19 is causing untold challenges to health care and wider social structures. Among the vulnerable populations are persons who smoke or vape, use opioids, or have a substance use disorder (SUD). Because of direct challenges to respiratory health, those with SUD may be especially susceptible to infection by the virus that causes COVID-19 and associated complications.
Smoking and vaping have harmful effects on the body, including making it harder for the body to fight infections. This includes serious infections like COVID-19.
