Summary
This study is proposing a four condition Electronic Tobacco Marketplace (ETM) study to determine if banning normal nicotine content (NNC) is sufficient for encouraging smokers to switch to potentially less harmful products or if the availability of higher nicotine and/or flavored alternative products (specifically e-cigarettes) are needed to achieve maximal reductions in smoking.
