Biomarkers of Nicotine and Tobacco Carcinogen Exposure in Socioeconomically Disadvantaged Black Adults Receiving a Brief Smoking Reduction Intervention.

ABSTRACT:

Background

Retrospective reporting of cigarette use can affect the accuracy of outcomes in tobacco treatment trials. The inclusion of objective measures of smoking, such as biomarkers of nicotine and tobacco exposure, is recommended. Most trials examining biomarkers after a behavioral intervention have included predominantly White adults enrolled in cessation, versus reduction, trials. The current study examined biomarkers of nicotine and tobacco exposure within a harm reduction trial in Black adults who smoke (AWS).

Methods

Nontreatment-seeking socioeconomically disadvantaged Black AWS (N = 65) were randomized to a treatment-as-usual control or enhanced care single-session intervention aimed to reduce their smoking. Biospecimens were collected at baseline and 1 month after
