immune response provided by nasal mucous membranes is compromised in cigarette smokers, which causes them to be more susceptible to the outcomes of a viral infection, said Ilona Jaspers, deputy director of the Center for Environmental

immune suppression effects in e-cigarette users than in smokers of traditional cigarettes.
