Initiation Sequence of E-Cigarette and Cigarette Smoking among US Adolescents: A National Study.

CONCLUSIONS: Adolescents who report a history of both e-cigarette use and cigarette smoking should be considered at high risk for substance-related problems. Early initiation of e-cigarette use is a signal for other substance use. SCIENTIFIC SIGNIFICANCE: Youth substance use prevention programs and prospective studies must take into account polysubstance use when addressing the relationships between e-cigarette use and cigarette smoking.
