Flavored Electronic Nicotine Delivery Systems to Lower Smoking and Exposure to Tobacco Toxicants Among Cigarette Smokers Interested in Quitting, REFLECT Trial

This clinical trial studies whether different flavored electronic nicotine delivery systems (ENDS) help lower smoking and exposure to tobacco toxicants among cigarette smokers interested in reducing their smoking. ENDS are battery-powered electronic devices designed to deliver a nicotine-containing liquid solution for inhalation. They do not burn tobacco. Previous research has shown that ENDS have the potential to lower exposure to potentially toxic substances compared to burned cigarettes as well as lower short-term adverse health outcomes. However, there are many different ENDS products with varying characteristics, including different flavors, and a need remains to understand more how flavors affect ENDS use, the potential reduction in cigarette use, and exposure to toxicants. This trial studies how two different flavors, fruit and tobacco, affect an individual's smoking behavior and ultimately whether flavored ENDS can help lower smoking and exposure to tobacco toxicants among cigarette smokers interested in reducing their smoking.
