The level of TD among most U.S. tobacco users was stable over the first three waves of the PATH Study and trends in levels of TD were predominantly unrelated to changes in patterns of continued product use. Stable levels of TD suggest a population at persistent risk of health impacts from tobacco. Wave 1 e-cigarette users, including those maintaining exclusive e-cigarette use experienced increasing levels of TD over time, perhaps due to increases in quantity or frequency of their e-cigarette product use or increasing efficiency of nicotine delivery over time.
