They concluded: “Using a microsimulation mannequin, we discovered that antiretroviral-adherent individuals dwelling with HIV in the United States who smoke cigarettes are 6 to 13 occasions more more likely to die from lung most cancers than from AIDS-associated causes …
“Clinicians caring for PLWH [people living with HIV] ought to supply guideline-based mostly behavioural and pharmacologic remedies for tobacco use.
