Comparison of methods for measurement of smoking behavior: mouthpiece-based computerized devices versus direct observation.

ABSTRACT:

Introduction

Understanding factors that influence tobacco use often involves detailed assessment of smoking behavior (i.e., puff topography) via mouthpiece-based, computerized devices. Research suggests that the use of a mouthpiece to evaluate topography may alter natural smoking behavior. This study was designed to compare topography measurement using mouthpiece-based methods (i.e., desktop and portable computerized devices) to methods that do not use a mouthpiece (i.e., direct observation).

Methods

A total of 30 smokers (> or =15 full-flavor or light cigarettes/day) participated in six Latin square-ordered, 2.5-hr experimental sessions that were preceded by at least 8 hr of objectively verified tobacco abstinence (carbon monoxide level < or = 10 ppm). Each session consiste
