Limited research has examined polysubstance use profiles among young adults focusing on the various tobacco products currently available. We examined use patterns of various tobacco products, marijuana, and alcohol using data from the baseline survey of a multiwave longitudinal study of 3418 students aged 18-25 recruited from seven U.S. college campuses. We assessed sociodemographics, individual-level factors (depression; perceptions of harm and addictiveness,), and sociocontextual factors (parental/friend use). We conducted a latent class analysis and multivariable logistic regression to examine correlates of class membership (Abstainers were referent group). Results indicated five classes: Abstainers (26.1% per past 4-month use), Alcohol only users (38.9%), Heavy polytobacco users (7.3%), Light polytobacco users (17.3%), and little cigar and cigarillo (LCC)/hookah/marijuana co-users (10.4%). The most stable was LCC/hookah/marijuana co-users (77.3% classified as such in past 30-day and 4-month timeframes), followed by Heavy polytobacco users (53.2% classified consistently). Relative to Abstainers, Heavy polytobacco users were less likely to be Black and have no friends using alcohol and perceived harm of tobacco and marijuana use lower. Light polytobacco users were older, more likely to have parents using tobacco, and less likely to have friends using tobacco. LCC/hookah/marijuana co-users were older and more likely to have parents using tobacco. Alcohol only users perceived tobacco and marijuana use to be less socially acceptable, were more likely to have parents using alcohol and friends using marijuana, but less likely to have friends using tobacco. These findings may inform substance use prevention and recovery programs by better characterizing polysubstance use patterns.

Objectives. To assess the effects of work requirements for able-bodied adults without dependents in the Supplemental Nutrition Assistance Program (SNAP). Methods. We used changes in waivers of work requirements to assess the impact of requiring work on the number of SNAP participants and benefit levels in 2410 US counties from 2013 to 2017 using 2-way fixed effects models. Results. Adoption of work requirements was followed by reductions of 3.0% in total SNAP participation, 4.5% in SNAP households, and 3.8% in SNAP benefit dollars, after controlling for the unemployment, poverty, and Medicaid expansions. Because able-bodied adults without dependents comprise 8% to 9% of all SNAP participants, our findings indicate that work requirements caused more than one third of able-bodied adults without dependents to lose benefits. Conclusions. Expansions of work requirements caused about 600 000 participants to lose SNAP benefits from 2013 to 2017 and caused a reduction of about $2.5 billion in federal SNAP benefits in 2017. The losses occurred rapidly, beginning a few months after work requirements were imposed. Public Health Implications. SNAP work requirements rapidly reduce caseloads and benefits, reducing food and health access. Effects on participation could be similar for work requirements in Medicaid or other programs.

Objectives With increased alternative tobacco product (ATP) use and lagging public health action, we explored perceptions of ATPs, anti-tobacco messaging, and tobacco regulation among young adults. Methods Semi-structured interviews were conducted with 60 Georgia college students aged 18-25 using: (1) cigarettes, little cigars/cigarillos (LCCs), smokeless tobacco, or e-cigarettes ≥15 days of the past 30; or (2) hookah ≥10 of the past 30 days (due to lower frequency of use). Of 99 participants recruited, 80 consented, and 60 participated. Results Participants were on average 21.01 years old (SD = 2.07), 56.7% women, and 65.0% black; 56.7% reported current use of cigarettes, 43.3% LCCs, 26.7% smokeless tobacco, 45.0% e-cigarettes, and 41.7% hookah. Cigarettes were perceived as most harmful to health and most addictive. E-cigarettes and hookah were generally regarded as lowest risk. Many indicated that ATP risk information was limited or inaccessible and that most anti-tobacco campaigns were irrelevant to ATPs. Participants requested more research and dissemination of evidence regarding ATP risks and need for ATP regulation. Conclusions In light of low risk perceptions regarding ATPs among young adults, research, anti-tobacco campaigns, and regulation must address their known and potential risks.

IMPORTANCE Increased work requirements have been proposed throughout federal safety net programs, including the Supplemental Nutrition Assistance Program (SNAP). Participation in SNAP is associated with reduced food insecurity and improved health. OBJECTIVES To determine whether SNAP work requirements are associated with lower rates of program participation and to examine whether there are racial/ethnic disparities or spillover effects for people with disabilities, who are not intended to be affected by work requirements. DESIGN, SETTING, AND PARTICIPANTS This nationally representative, pooled cross-sectional study examined how changes in SNAP work requirements at state and local levels in the US are associated with changes in food voucher program participation. The study combined information on state and local SNAP work requirements with repeated cross-sections from the 2012 through 2017 American Community Survey (with outcomes covering 2013 to 2017). The analytical approaches were based on difference-indifference and triple-difference methods, after controlling for other economic and social factors. The sample included low-income adults without dependents, stratified by racial/ethnic group and disability status. The study also included parents who would otherwise meet work requirement criteria as a comparison group to estimate triple-difference models. This accounted for otherwise unobserved factors affecting trends in SNAP participation within local areas.
