Even so, significantly less research has examined risk factors for initiating nicotine vaping in early adolescence. This paper addresses this gap in the literature by examining risk factors for initiating nicotine vaping in a sample of middle- and high-school students. In order to do so, we analyze data from the 2019 cohort of the Florida Youth Substance Abuse Survey (FYSAS). We employ multinomial logistic regression and logistic regression to examine potential risk factors for early age of nicotine vaping initiation. Our findings reveal that early age of nicotine vaping initiation is associated with cigarette use, alcohol use, having substance using peers, lifetime incidence of arrest, and lifetime incidence of school suspension. In conclusion, our findings reveal that early age of nicotine vaping initiation is associated with other forms of risky behavior in adolescence (i.e., substance use, misbehavior leading to arrest and/or school suspension). We discuss the implications of these findings for future research.More than half of U.S. states legalized medical or recreational sale and possession of cannabis since the prevalence of cannabis use was last estimated among U.S. military veterans in 2014. To provide updated estimates of the prevalence and correlates of cannabis use, cannabis use disorder (CUD), and medical cannabis card possession in this population, data were analyzed from the 2019-2020 National Health and Resilience in Veterans Study, a nationally representative survey of 4,069 veterans ages 22-99 years who reported on their past-6-month cannabis use, CUD symptoms, and possession of a medical cannabis card. An estimated 11.9% [95% confidence interval (CI) = 10.9-12.9%)] of veterans reported using cannabis, 2.7% (95% CI = 2.3-3.3%) screened positive for CUD, and 1.5% (95% CI = 1.2-2.0%) r
