Age of tobacco use initiation and association with current use and nicotine dependence among US middle and high school students, 2014–2016

Abstract

First tobacco use at age ≤13 years is associated with current daily and past 30-day use of non-cigarette tobacco products, and with the development of nicotine dependence among youth ever-users. Proven tobacco prevention interventions that reach early adolescents are important to reduce overall youth tobacco use.
