“…Poly drug use has been linked with a variety of medical, psychological, and psychosocial harms among adolescents (Bohnert et al, 2014;Fallu et al, 2014;Felton et al, 2015;Kelly, Chan, et al, 2015;Kelly, Evans-Whipp, et al, 2015;Peters et al, 2012). The severity of these harms highlights the importance of identifying the factors that contribute to the consumption of multiple substances to inform future prevention programs (Hublet et al, 2015;Marshall, 2014).…”

“…This was deemed a "small but notable proportion" by the authors (p.632). Poly drug use by adolescents has been linked with school non-completion, low academic achievement, psychosocial problems, depressive symptoms, psychological distress, legal problems, interpersonal difficulties, risky sexual practices, and physical health issues (Bohnert et al, 2014;Connell, Gilreath, & Hansen, 2009;Fallu, Brière, & Janosz, 2014;Felton, Kofler, Lopez, Saunders, & Kilpatrick, 2015;Kelly, Chan, Mason, & Williams, 2015;Kelly, Evans-Whipp, et al, 2015;Peters et al, 2012). Poly drug use among adolescents thus represents a significant public health issue, resulting in calls for a more comprehensive and integrated approach to youth prevention programs (Camenga, Klein, & Roy, 2006;Hale, Fitzgerald-Yau, & Viner, 2014;Leatherdale, Hammond, & Ahmed, 2008;Wiefferink et al, 2006).…”

Poly drug use in adolescents represents a significant public health issue, heightening risk for abuse, dependency, and a variety of short-and long-term psychological, psychosocial, and health consequences. However, past studies have typically examined just one or two substances in isolation and there is a lack of research that has comprehensively examined possible predictors of poly drug use in adolescents. To inform the development of comprehensive prevention programs that can simultaneously target multiple substances, the present study sought to identify psychological, environmental, and demographic factors that are most strongly associated with alcohol, tobacco, and cannabis poly drug use. Adolescents aged 15 to 17 years (n=1661; 50.9% male) completed a survey on their use of alcohol, tobacco, and cannabis over the last 30 days. Various psychological, environmental, and demographic factors were also assessed. Weighted multiple-level logistic regression was conducted to assess the factors associated with poly drug use. In total, 20.3% of respondents had used at least one substance, 6.7% reported using two substances, and 3.3% reported using all three substances. The most common combined pattern of use was alcohol and tobacco, followed by alcohol and cannabis. Several factors emerged as significant, with conduct problems, depression, and the school environment accounting for the most variance. Specific psychological and environmental factors appear to be particularly important domains to target in adolescent substance use prevention programs. Early identification of adolescent depression and conduct problems and the development of programs that address these symptoms in youth may be effective approaches to delaying or preventing poly drug use in this population.

“…Polydrug use in adolescence is common; for example, 41% of U.S. 10th graders (μ age = 16) reported concurrent use of tobacco, alcohol, and marijuana in 2010 (Conway, Vullo, Nichter, et al, 2013). Polydrug use is associated with worse health and social outcomes (Fallu, Brière, & Janosz, 2014; Kelly, Evans-Whipp, Smith, et al, 2015) compared to single-substance use, including cognitive deficits (Hanson, Medina, Padula, et al, 2011) and substance-related legal, relational, and work problems in young adulthood (Griffin, Bang, & Botvin, 2010). Moreover, adolescent smokers and polydrug users are more likely to report symptoms of depression.…”

“…Use of a single substance (e.g., alcohol, marijuana, or other drugs) anytime during childhood, adolescence, and emerging adulthood predicts major depressive disorder at age 27, (Brook et al, 2002) and both current and lifetime nicotine dependence are associated with persistent depressive symptoms (Hu, Davies, & Kandel, 2006). Each of these outcomes is linked to enduring physical, social, and mental health problems, the consequences of which are more severe for adolescents who initiate early (Fallu et al, 2014; Taylor, Malone, Ianoco, et al, 2002). Hence, it is important to identify dominant patterns of polydrug use among adolescent smokers to best inform prevention and cessation interventions in this high-risk population.…”

Purpose Adolescent smokers are at increased risk for polydrug use, which is associated with more consequences than use of a single drug. Here we classified subgroups of polydrug use among urban adolescent cigarette-smokers; described the sociodemographic, smoking, and depression correlates; and identified three-year outcomes associated with subgroup membership. Methods Adolescent cigarette smokers (N = 176; Mage = 16.1; 35% male; 27% white) completed surveys assessing drug use, smoking characteristics, demographics, and depressive symptoms at baseline and 12, 24, and 36 months follow-up. Results Almost all participants (96%) reported using, on average, two (SD = 0.97) substances (including other tobacco products) in addition to cigarettes. Latent class analysis revealed two distinct classes of polydrug users. “Limited Range Use” (84%) class members reported current use of other tobacco, alcohol, and marijuana, as did “Extended Range Use” class members (16%) who also reported current use of “harder drugs” (i.e., cocaine/crack, hallucinogens, ecstasy, and misused prescriptions). The classes did not differ on demographics or baseline likelihood of marijuana (χ2 = 0.25; p <0.62) or alcohol use (χ2 = 3.3; p <0.07). At baseline, a larger proportion of Extended Range Use class members reported both smoking the entire cigarette and symptoms of clinical depression. Extended Range Use class membership at baseline predicted higher mean depression scores at 24 and 36 months. Conclusion Adolescent cigarette-smokers who reported extended range use (18%) also reported symptoms of clinical depression at baseline and follow-up. These findings indicate a need for early monitoring of depression symptoms and prevention and cessation interventions targeting this high-risk group.

“…First, Serafini et al ( 8 ) explore the possible role of hopelessness as a mediator in the relationship between early cannabis use and suicidal behaviors, while Little et al ( 9 ) investigate predictors of cannabis cessation within a sample of high-school students. The next article, by Fallu et al ( 10 ), reports the findings of a latent class analysis of adolescent cannabis users, revealing four different use trajectories. The early onset, heavy cannabis and polydrug use group in this study were found to experience the highest level of use-related problems, followed by the late-heavy-polydrug group.…”
