“From our perspective, use of E-cigarettes should be encouraged as a substitute for conventional cigarettes for cigarette smokers who are unable or unwilling to quit, but are sincerely interested in reducing their risk of tobacco-related illness. E-cigarettes deliver the nicotine desired by inveterate smokers, with only the tiniest traces of carcinogens or other hazardous chemicals. The nicotine used in these products contains the same trace contaminants and trace carcinogens found in the pharmaceutical nicotine-replacement products approved by FDA.”
