E-cigs are electronic devices that allow users to inhale nicotine vapor (“vaping”). They are largely unregulated in the United States. This research provided in-depth, longitudinal information, based on real-time reports, which addressed key priorities that may inform regulatory and health agencies, including understanding the relations between vaping and:

1) Nicotine dependence;
2) Changes in rates of smoking conventional cigarettes;
3) Health outcomes such as evidence of exposure to carcinogens, as well as acute and long-term pulmonary health;
4) Attempts to quit smoking and the success of those attempts.

Specifically, UW-CTRI identified and followed over time:

1) 150 participants who exclusively smoke cigarettes.
2) 250 participants who both smoke and vape.

Researchers used smart phones and other tools to collect information on patterns of use of these products, levels of addiction, withdrawal symptoms, success quitting versus relapse, lifestyle factors, carcinogen exposure, and how one group of participants compares to the other over time.

“This research will allow us to examine the public health effects of smoking and vaping during this critical period of emerging policy discussions,” said UW-CTRI Associate Director of Research Dr. Megan Piper, co-principal investigator on the grant with UW-CTRI Director of Clinical Services Dr. Douglas Jorenby.
