Some e-cigarette companies are substituting nicotine with more potent, nicotine-mimicking chemicals that evade U.S. Food and Drug Administration (FDA) regulation, recent research shows.
Researchers at Duke and Yale University found that the amount of nicotine-mimicking chemicals, or nicotine analogs, in e-cigarette products may differ from what is on the label. Some product labels do not specify that they contain certain nicotine analogs, while some products contain fewer nicotine analogs than what is shown on the label.
