About

This study will test feasibility, in smokers with lung, head & neck, and bladder cancers, that examines the effect of e-cigarette substitution, on measures of smoking-related toxicity and medical outcomes. The aim of the study is to determine the appeal of e-cigarettes compared to regular combustible cigarettes.

Full description

The aim of the study is to determine the appeal of e-cigarettes compared to combustible cigarettes as measured by the degree to which patients succeed in reducing their cigarette consumption over the 9 weeks they are supplied with product, along with their consumption of e-cigarettes. We will measure past use of e-cigarettes and cigarettes at baseline, 3, 6, 9, and 12 weeks. We will also assess the effect of e-cigarette substitution on toxicity by measuring expired carbon monoxide and urine NNAL (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol) , a carcinogenic metabolite of cigarette smoke.
