Included in a recent editorial, Dr. Michael Katz mentioned that the FDA should monitor electronic cigarettes as a nicotine delivery tool, and that electronic cigarettes should continue to be banned in locations where typical tobacco products are not allowed. “Unfortunately, the evidence on whether e-cigarettes help smokers to quit is contradictory and inconclusive,” Katz wrote. He did say he was willing to support their use if “there were good data indicating that they helped smokers to stop.” Dr. Gilbert Ross, medical and executive director of The American Council on Science and Health, said “allowing e-cigs to compete with cigarettes in the marketplace might decrease smoking-related morbidity and mortality.”

If there were any evidence that electronic cigarettes inhibit, rather than enhance smoking cessation, I too would join Dr. Glantz's camp and oppose electronic cigarettes. But such evidence does not exist. Not a shred of it so far. Not a single study suggests that electronic cigarette use results in lower quit rates than what would occur in the absence of electronic cigarette use among smokers who try these products.
