Full description

Investigators are doing this study with people who smoke and have chronic obstructive pulmonary disease (COPD). Investigators are trying to find out if e-cigarettes can reduce tobacco-related harm among smokers. Investigators want to know if training on e-cigarette use will help smokers switch to e-cigarettes. If training helps, how much training is needed for people to fully switch from cigarettes to e-cigarettes? This study is an in-lab smoking study and randomized trial. The study takes place at the Main University of Kansas Medical Center (KUMC) campus in Kansas City, Kansas (KS). device. Participants will come to the lab on seven separate days. Between visits, participants will use the study e-cigarette at home. Each time participants come in, participants will fill out surveys about participants tobacco use and use the study product. Investigators will ask participants to switch to the study e-cigarette for 12 weeks during the study.

The study product is an e-cigarette device and is available for sale in the US. Participants will do a few different breathing tests where participants blow into a machine, Investigators will measure participants blood pressure and pulse, and Investigators will do a short walking test. Before three of the visits Investigators will ask participants to not smoke or use an e-cigarette for 12 hours leading up to the visit. During three of the visits, Investigators will ask participants to use the e-cigarette for 30 minutes and take two blood samples. Each visit will last about 2-4 hours. There will be a total of seven visits.
