Does the Magnitude of Reduction in Cigarettes Per Day Predict Smoking Cessation? A Qualitative Review.

ABSTRACT:

Introduction

Reduction in cigarettes per day (CPD) aided by nicotine replacement therapy (NRT) increases cessation in smokers; however, it is unclear whether this is due to use of NRT or reduction per se. If the latter, a greater magnitude of reduction in CPD should increase the odds of cessation.

Methods

The authors searched PubMed, Cochrane, PsychINFO, http://clinicaltrials.gov and their personal libraries for studies on smoking reduction. Seven of the 76 (9%) identified intervention trials and four of 28 naturalistic studies (14%) reported on the magnitude of reduction in relation to the odds of cessation.

Results

Five of the seven intervention trials and three of the four naturalistic observational (cohort) studies found that increased reduction in CPD was associa
