Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The main goal of this project is to compare two different approaches to reducing levels of nicotine in cigarettes: an immediate reduction in nicotine content in cigarettes to non-addictive levels or a gradual reduction in nicotine content in cigarettes to non-addictive levels. These two approaches will then be contrasted to a group that continues to smoke cigarettes with nicotine content similar to conventional cigarettes.
