Background: Research characterizing patterns of tobacco and cannabis use by product type and route of administration among youth and young adults (YAs) is limited. Methods: We conducted latent class analysis of tobacco and cannabis use (i.e., cigarettes, electronic nicotine delivery systems (ENDS), cigars, blunts, cannabis vaping, and other cannabis use (without blunting/vaping)) among youth (ages 15-17) and YAs (ages 18-24) who used at least one product in the past 30 days, using data from the Population Assessment of Tobacco and Health Study (Wave 4, 2016-2017). We used multinomial logistic regression models to examine associations between sociodemographic characteristics and use classes. Results: The latent use classes for youth included cigarettes (2.5%), ENDS (2.6%), blunts (2.5%), other cannabis (6.3%), ENDS + cannabis vaping (2.7%), and cigarettes + cigars + other cannabis (1.5%), while the latent use classes for YAs included cigarettes (11.7%), ENDS (3.9%), blunts (5.3%), other cannabis (7.0%), cigarettes + cigars (8.2%), and cigarettes + ENDS + cannabis vaping (4.9%). We compared use classes to never/former use for youth (82.0%) and YAs (59.0%) and found that they differed by each sociodemographic characteristic. For example, non-Hispanic Black YAs had higher odds of cigarettes + cigar use compared to non-Hispanic White YAs, whereas racial/ethnic minority youth and YAs had lower odds of other dual/poly use groups compared to their non-Hispanic White counterparts. Conclusions: We observed differences in use classes by sociodemographic characteristics for youth and YAs. Health professionals must consider tobacco and cannabis use patterns when implementing prevention and cessation interventions. [ABSTRACT FROM AUTHOR]

To examine associations of concern, worry, and stress about discrimination, shootings/violence, and police brutality and exclusive and dual tobacco and cannabis use among young adults. A prospective, racially/ethnically diverse cohort of young adults (n = 1960) living in Los Angeles, California completed a baseline survey in 2020 (age range: 19–23) and a follow-up survey in 2021. Exploratory factor analysis (EFA) was employed on nine variables assessing levels of concern, worry, and stress about societal discrimination, societal shootings/violence, and community police brutality at baseline. Past 30-day tobacco and cannabis use at follow-up was categorized as current exclusive tobacco, exclusive cannabis, and dual tobacco and cannabis (vs never/former) use based on eleven use variables. Multinomial logistic regressions estimated adjusted associations between each factor score (translated to standard deviation units) with exclusive and dual tobacco and cannabis use. The EFA produced four factor scores representing concern/worry/stress (i.e., distress) about community police brutality (F1), distress about societal shootings/violence (F2), and distress about societal discrimination (F3), as well as generalized stress about police brutality, shootings/violence, and discrimination (F4). F1, F2, and F3 were associated with subsequent exclusive current cannabis use, with F1 having the strongest association (OR: 1.35, 95% CI: 1.18–1.55), while only F1 (OR: 1.51, 95% CI: 1.27–1.78) was associated with dual tobacco and cannabis use. None of the factors were associated with exclusive tobacco use. Young adult concern, worry, and/or stress about social problems may increase risk of cannabis use with or without concurrent tobacco use 6–12 months later. • Approximately 14% of young adults used dual tobacco and cannabis. • Distress about most social problems were associated with exclusive cannabis use. • Distress about police brutality was associated with dual tobacco and cannabis use.

Racial/ethnic discrimination (hereafter, discrimination) is associated with use of individual tobacco and cannabis products. However, we know little about how discrimination affects dual/polytobacco and cannabis use and associated use disorders. We used cross-sectional data on adults (18+) from the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (n = 35,744). We defined past-year discrimination as a summary scale (range: 0–24) based on six scenarios. We created a mutually exclusive six-category use variable: noncurrent, individual tobacco and noncannabis, individual tobacco and cannabis, individual cannabis and nontobacco, dual/polytobacco and noncannabis, and dual/polytobacco and cannabis based on past 30-day tobacco use of four products (i.e., cigarettes, electronic nicotine delivery systems, other combustibles (cigars, pipe), smokeless tobacco) and cannabis use. We also examined past-year tobacco use disorder (TUD) and cannabis use disorder (CUD) as a four-level variable: no disorders, TUD only, CUD only, and TUD and CUD. We estimated associations between discrimination and each outcome using adjusted multinomial logistic regression and assessed effect modification by stratifying adjusted models by race/ethnicity (i.e., Hispanic, non-Hispanic (NH) White, NH Black, and another race/ethnicity). Experiencing more discrimination was associated with each outcome but was most strongly associated with dual/polytobacco and cannabis use (OR: 1.13, 95 % CI: 1.07–1.19) and joint TUD and CUD (OR: 1.16, 95 % CI: 1.12–1.20). Models stratified by race/ethnicity showed that discrimination was associated with dual/polytobacco and cannabis only among NH White adults, and with joint TUD and CUD only among NH Black and NH White adults. Discrimination was associated with tobacco and cannabis use outcomes among multiple adult racial/ethnic populations, but associations were more profound for NH White and NH Black adults than adults from other racial/ethnic populations. • Experiencing more discrimination was linked to dual/polytobacco and cannabis use. • Discrimination was also associated with joint tobacco and cannabis use disorders. • For each race/ethnicity, discrimination was linked to at least one use outcome. • Associations with more severe outcomes were stronger for White and Black adults.

Background: It is unknown whether increasing attention to police brutality is a source of stress associated with substance use risk among young people.Methods: A longitudinal racially/ethnically diverse cohort from Los Angeles, California (n = 1797) completed baseline (2017; mean age: 17.9) and follow-up (2020; mean age: 21.2) surveys assessing level of concern, worry, and stress about police brutality (range: 0 'not at all' - 4 'extremely') and past 30-day nicotine, cannabis, alcohol, other drug, and number of substances used (0-19). Regression models, adjusted for demographic characteristics and baseline substance use, evaluated whether changes in distress about police brutality from 2017 to 2020 were associated with substance use in 2020 overall and stratified by race/ethnicity.Results: Distress about police brutality increased between 2017 (mean: 1.59) and 2020 (mean: 2.43) overall. Black/African American and Hispanic/Latino respondents consistently had the highest mean distress levels at both timepoints. In the full sample, each one-unit greater increase in distress about police brutality from 2017 to 2020 was associated with 11% higher odds of cannabis use, 13% higher odds of alcohol use, and 8% higher risk of using an additional substance for the number of substances used outcome. Race/ethnicity-stratified models indicated that greater increases in distress from 2017 to 2020 was associated with substance use among Black/African American, Hispanic, and multiracial respondents in 2020, but not Asian American/Pacific Islander and White respondents.Conclusions: Distress about police brutality may be associated with substance use, particularly among certain racial/ethnic minority young people. Further investigation of whether police brutality affects health in disparity populations is needed. [ABSTRACT FROM AUTHOR]- Published
