RESUMEN
INTRODUCTION: In the US, having a 21 minimum legal sales age for tobacco (T21) at the state level may have impacted age verification of cigarette and e-cigarette purchases among U.S. young adults (ages 18-26), before and/or after federal T21 implementation. AIMS AND METHODS: This study examined this by analyzing data from cigarette and/or e-cigarette users (nâ =â 618 and nâ =â 864) in six metropolitan areas in six states. Participants reported frequency of being age verified ("almost always" vs. less frequently) for cigarette and/or e-cigarette purchases across 3 timepoints (ie, wave 1 [w1]: September-December 2018, w2: September-December 2019, and w3: September-December 2020). Multilevel modeling examined time-varying state T21 status and time (reflecting federal T21 implementation) in relation to age verification of cigarette and e-cigarette purchases, respectively. RESULTS: The proportions almost always age verified for cigarette purchases in states with T21 versus without were: W1: 38.5% versus 37.7%, w2: 33.0% versus 39.1%, and w3: 45.4% versus 30.6%. For e-cigarettes, the proportions were: W1: 30.6% versus 40.3%, w2: 42.3% versus 50.5%, and w3: 56.0% versus 58.3%. In multilevel modeling, state T21 status was associated with greater likelihood of age verification for e-cigarettes (aORâ =â 1.67, CIâ =â 1.13 to 2.45), but not for cigarettes. Age verification increased over time for e-cigarettes-both accounting for and not accounting for state T21 status. There were no changes for cigarettes. CONCLUSIONS: State T21 status and time correlated with age verification for e-cigarettes, but not cigarettes. These self-reported age verification data contribute to evidence from compliance checks, indicating that retailers require additional prompts and enforcement to enhance compliance with T21 laws. IMPLICATIONS: Current findings suggest that variations in regulations and gaps in enforcement may hinder the potential impact of increasing the minimum legal sales age, which ultimately may undermine the promise of such policies, specifically with regard to preventing tobacco use among the underage. Therefore, it is crucial to monitor retailer compliance with T21 laws and evaluate their efficacy to increase ID checks, minimize illegal sales, and curb underage use of tobacco. Relatedly, particular attention to enforcement efforts that may promote compliance is warranted.

BACKGROUND AND OBJECTIVES: Limited research has examined mechanisms, including parenting behaviors, contributing to tobacco use disparities among sexual minority young adults (SMYAs). METHODS: Participants were 644 young adult (ages 18-29; 36.5% racial/ethnic minority) women (N = 416; 44.7% bisexual, 7.2% lesbian, 48.1% heterosexual) and men (N = 288; 11.0% bisexual, 13.2% gay, 75.9% heterosexual). Bivariate analyses examined differences among sex-by-sexual identity subgroups in perceived parenting (psychological control, behavioral control, knowledge, autonomy support, warmth, communication), past 30-day cigarette, e-cigarette, and cigar use, and likelihood of future use. Multivariable regression examined associations of sexual identity subgroup and parenting behaviors to tobacco use outcomes among women and men. RESULTS: Bisexual (vs. heterosexual) women reported greater parental psychological control and less autonomy support, warmth, and communication. Bisexual (vs. heterosexual) women had greater odds of past 30-day cigarette and cigar use and greater likelihood of future cigarette and e-cigarette use, and parenting behaviors were associated with past 30-day cigarette (knowledge, warmth), e-cigarette (psychological control, autonomy support, warmth), and cigar use (behavioral control, warmth) and likelihood of future cigarette (psychological control, warmth) and e-cigarette use (autonomy support, communication). Gay (vs. heterosexual) men reported greater parental behavioral control, less knowledge, autonomy support, warmth, and communication. Sexual identity and parenting behaviors were largely not associated with tobacco use among men. DISCUSSION AND CONCLUSIONS: Findings highlight the role of parenting behaviors as potential mechanisms contributing to tobacco use disparities among SMYA women. SCIENTIFIC SIGNIFICANCE: Tobacco prevention/cessation programs should be tailored toward specific SMYA subgroups, combinations of parenting behaviors, and patterns of tobacco use.

Idiopathic pulmonary fibrosis (IPF) is a particularly deadly form of pulmonary fibrosis of unknown cause. In patients with IPF, high serum and lung concentrations of CHI3L1 (chitinase 3 like 1) can be detected and are associated with poor survival. However, the roles of CHI3L1 in these diseases have not been fully elucidated. We hypothesize that CHI3L1 interacts with CRTH2 (chemoattractant receptor-homologous molecule expressed on T-helper type 2 cells) to stimulate profibrotic macrophage differentiation and the development of pulmonary fibrosis and that circulating blood monocytes from patients with IPF are hyperresponsive to CHI3L1-CRTH2 signaling. We used murine pulmonary fibrosis models to investigate the role of CRTH2 in profibrotic macrophage differentiation and fibrosis development and primary human peripheral blood mononuclear cell culture to detect the difference of monocytes in the responses to CHI3L1 stimulation and CRTH2 inhibition between patients with IPF and normal control subjects. Our results showed that null mutation or small-molecule inhibition of CRTH2 prevents the development of pulmonary fibrosis in murine models. Furthermore, CHI3L1 stimulation induces a greater increase in CD206 expression in IPF monocytes than control monocytes. These results demonstrated that monocytes from patients with IPF appear to be hyperresponsive to CHI3L1 stimulation. These studies support targeting the CHI3L1-CRTH2 pathway as a promising therapeutic approach for IPF and that the sensitivity of blood monocytes to CHI3L1-induced profibrotic differentiation may serve as a biomarker that predicts responsiveness to CHI3L1- or CRTH2-based interventions.

OBJECTIVE: As the U.S. cannabis market expands, surveillance of retailer practices, especially product health claims and risks, is crucial to protect consumers. In this study, mystery shoppers (i.e., staff not explicitly identified as researchers) examined retail personnel communication regarding product recommendations, health benefits, safety, and/or risks among U.S. cannabis retailers. METHOD: In Summer 2022, mystery shoppers audited 140 licensed cannabis retailers in 5 cities in states with established nonmedical (i.e., recreational) cannabis sales and diverse regulations (Denver, Colorado; Seattle, Washington; Portland, Oregon; Las Vegas, Nevada; Los Angeles, California). Descriptive and bivariate analyses characterized retail personnel communication overall and across cities. RESULTS: Common product recommendations for new users included edibles, pre-rolled joints, and bud/flower, and 8.6% offered free/inexpensive ways to sample products. Although Colorado, Washington, and Oregon explicitly prohibited health claims in advertising or labels, more than 90% of retailers there endorsed use for anxiety, insomnia, and/or pain. Whereas 54.3% endorsed use for pregnancy-related nausea (least common in Denver, 23.3%; most common in Seattle, 76.7%), 26.4% warned against use during pregnancy (most frequently in Denver, 46.7%; least frequently in Seattle and Portland, 13.3%). Overall, 52.1% warned against driving after use (most frequently in Denver, 80.0%; least frequently in Las Vegas, 20.0%). Almost all (≥90%) sold cannabidiol (CBD) products and endorsed their health benefits and safety, but few (<10%) sold or endorsed delta-8 tetrahydrocannabinol (THC), etc. (all of which were in Los Angeles). CONCLUSIONS: Ongoing cannabis retail surveillance, particularly using protocols assessing factors outside those visibly observable, is needed to inform regulatory and enforcement efforts, especially related to health claims.

BACKGROUND: Understanding discrimination (e.g., microaggressions) toward sexual/gender minorities (SGM) and racial/ethnic minorities (REM) from an intersectional perspective is critical in informing interventions to reduce such experiences and their impacts. PURPOSE: This study examined US young adults identifying as SGM, REM, both, or neither in relation to microaggression experiences, and these factors in relation to mental health. METHODS: Using 2022 data from 932 US adults (Mage = 27.61) in an online survey study, we compared subgroups (SGM-only, REM-only, both, neither) in relation to microaggression experiences and mental health symptoms, stratified by sex (male, female). Multivariable linear regression examined: 1) sex and intersectional subgroup in relation to number of microaggressions experienced; and 2) sex, subgroup, and number of microaggression experiences in relation to mental health symptoms. RESULTS: Among females (n = 612), 42.0% were SGM-only, 17.3% REM-only, 15.2% both, and 25.5% neither. Among males (n = 320), 25.0% were SGM-only, 25.0% REM-only, 8.4% both, and 41.6% neither. Females (vs. males) reported more microaggressions (M = 5.67, SD = 3.00 vs. M = 3.95, SD = 3.46, p < .001). Those with intersecting minority identities experienced the most microagressions (females: M = 6.98, SD = 2.64; males: M = 6.44, SD = 2.95, respectively). In multivariable analyses, females and those in any of the 3 minority-identifying subgroups experienced more microaggressions; those with intersecting minority identities experienced more microaggressions than SGM-only and REM-only. Identifying as SGM-only or both SGM and REM, as well as experiencing more microaggressions, was associated with greater mental health symptoms. CONCLUSIONS: Intersecting minority identities increase risk for microaggressions and mental health consequences. Multilevel interventions must reduce minority subgroups' experiences of microaggressions and their impacts.
RESUMEN
INTRODUCTION: Limited research has examined differences in cigarette/e-cigarette use trajectories among specific subgroups of sexual minority (SM) young adult (SMYA) men and women. METHODS: Repeated measures latent profile analyses (RMLPAs) examined past 6-month cigarette and e-cigarette use trajectories across 5 waves of data (2018-2020) among men (n = 1235; Mage = 25.56, SD = 4.85; 8.0% bisexual, 12.7% gay; 36.4% racial/ethnic minority) and women (n = 1574; Mage = 24.64, SD = 4.72; 23.8% bisexual, 5.9% lesbian; 35.3% racial/ethnic minority) residing in 6 US metropolitan statistical areas. Multinomial logistic regressions examined associations among sexual orientation (bisexual, gay/lesbian, heterosexual) and tobacco use trajectories among men and women, separately. RESULTS: RMLPAs yielded a 6-profile solution: stable low-level cigarette and e-cigarette use (66.6%), stable low-level cigarette and high-level e-cigarette use (12.2%), stable low-level cigarette and decreasing e-cigarette use (6.2%), stable mid-level cigarette and low-level e-cigarette use (6.2%), stable high-level cigarette and low-level e-cigarette use (4.5%), and stable high-level cigarette and e-cigarette use (4.2%). Gay (vs. heterosexual) men were less likely to display stable low-level cigarette and stable high-level e-cigarette use. Bisexual (vs. heterosexual) women were more likely to display stable low-level cigarette and stable high-level e-cigarette use, stable low-level cigarette and decreasing high-level e-cigarette use, and stable high-level cigarette and stable low-level e-cigarette use. CONCLUSIONS: Bisexual women were at greatest risk for displaying several problematic cigarette and e-cigarette use trajectories, whereas few differences emerged for men. Tailored interventions and campaigns are needed to curtail ongoing tobacco use disparities among SMYA men and women, particularly bisexual women.

Background: With more states legalizing recreational cannabis, examining cannabis retail and marketing is crucial, as it may influence consumers' perceptions and behaviors. Particularly understudied is online cannabis retail. Methods: In Spring 2022, coders collected and analyzed data regarding retailer characteristics, age verification, and marketing strategies (e.g., product availability, health-related content, promotions, website imagery) among 195 cannabis retail websites in five U.S. cities (Denver, Colorado; Seattle, Washington; Portland, Oregon; Las Vegas, Nevada; Los Angeles, California). Descriptive analyses characterized the websites overall and across cities. Results: Overall, 80.5% verified age for website entry, and 92.8% offered online purchases (92.3% of retailers in Seattle, where prohibited). Of these, 82.9% required age verification for purchases, and 30.9% offered delivery. Almost all (>92%) offered flower/bud, concentrates, edibles, vaping devices, topicals, and tinctures. Health warnings were displayed on 38.3% of websites. Although all five states required health warnings regarding use during pregnancy, only 10.3% had these warnings. In addition, 59.0% posted some unsubstantiated health claims, most often indicating physical and mental health benefits (44.6%). Although Colorado, Washington, and Oregon prohibit health claims, 51.2-53.8% of these retailers posted them. Discounts, samples, or promotions were present on 90.8% of websites; 63.6% had subscription/membership programs. Subpopulations represented in website content included the following: 27.2% teens/young adults, 26.2% veterans, 7.2% sexual/gender minorities, and 5.6% racial/ethnic minorities. Imagery also targeted young people (e.g., 29.7% party/cool/popularity, 18.5% celebrity/influencer endorsement). Conclusions: Regulatory efforts are needed to better monitor promotional strategies and regulatory compliance (e.g., health claims, youth-oriented content, underage access) among online cannabis retailers.
