RESUMEN
OBJECTIVE: To evaluate the feasibility and accuracy of an unprecedented COVID-19 antigen testing program in schools, which required a healthcare provider order, laboratory director, a Clinical Laboratory Improvement Amendments certificate of waiver, as well as training of school personnel. STUDY DESIGN: Descriptive report of a point-of-care, school-based antigen testing program in California from August 1st, 2021 through May 30, 2022, in which participants grades K-12 self-swabbed and school personnel performed testing. Participants included 944 009 students, personnel, and community members from 4022 California kindergarten through high schools. Outcomes measured include sensitivity and specificity (with polymerase chain reaction [PCR] as comparator) of the Abbott BinaxNOW antigen test, number of tests performed, and active infections identified. RESULTS: Of 102 022 paired PCR/antigen tests, the overall sensitivity and specificity for the antigen test was 81.2% (95% CI: 80.5%-81.8%) and 99.6% (95% CI: 99.5%-99.6%), respectively, using cycle threshold values <30. During January through March 2022, the highest prevalence period, the positive predictive value of antigen testing was 94.7% and the negative predictive value was 94.2%. Overall, 4022 school sites were enrolled and 3 987 840 million antigen tests were performed on 944 009 individuals. A total of 162 927 positive antigen tests were reported in 135 163 individuals (14.3% of persons tested). CONCLUSIONS: Rapidly implementing a school-based testing program in thousands of schools is feasible. Self-swabbing and testing by school personnel can yield accurate results. On-site COVID-19 testing is no longer necessary in schools, but this model provides a framework for future infectious disease threats.
RESUMEN
As cannabis legalization expands and online marketing intensifies, this study examines whether online social cues can amplify youth-targeted cannabis advertising and whether cannabis warning labels (CWLs) can counteract these influences. A U.S. online sample of 970 adolescents and 1776 young adults susceptible to cannabis use were recruited from Qualtrics in summer 2022. Each participant was randomly assigned to one of the 3 (CWLs: none vs. textual vs. pictorial) by 3 (comments: none vs. anti-cannabis vs. pro-cannabis) conditions in an online experiment. Participants were exposed to three online marketing posts promoting marijuana edibles (randomly selected from a large pool, N = 1260), each with either no warning label, a textual warning, or a pictorial warning (text and picture), and with either five comments (pro- or anti-cannabis in valence) or none. Results showed that among adolescents, pro-cannabis comments increased product appeal (vs. anti-cannabis comments: b = 0.18, p = .025; vs. no comments: b = 0.21, p = .021), and did so more than young adults. For adolescents, only pictorial warnings reduced product appeal (b = -0.20, p = .028). For young adults, both pictorial (b = -0.18, p = .002) and textual warnings (b = -0.12, p = .029) reduced product appeal. Furthermore, both textual (adolescents: b = -0.20, p = .004; young adults: b = -0.15, p = .005) and pictorial (adolescents: b = -0.30, p < .001; young adults: b = -0.18, p = .001) warnings reduced cannabis use intentions. Findings support requiring enhanced CWLs accompany online marketing ads.

BACKGROUND: The full spectrum of associations between in utero cannabis exposure and adverse neonatal outcomes is still unclear. OBJECTIVE: This study aimed to evaluate the associations between in utero cannabis exposure and neonatal outcomes. STUDY DESIGN: This population-based retrospective cohort study of singleton births among Kaiser Permanente Northern California members (January 1, 2011-July 31, 2020) included parent-infant dyads in which the pregnant parent was screened for cannabis use as part of standard prenatal care, generally upon entrance into care. Data were ascertained from electronic health records. Generalized estimating equation models were adjusted for sociodemographic characteristics, other non-cannabis prenatal substance use, medical and mental health comorbidities, and adequacy of prenatal care. In utero cannabis exposure was defined as self-reported use since becoming pregnant and/or a positive urine toxicology test for cannabis at any time during pregnancy (yes/no; primary exposure). Frequency of use was self-reported and categorized as daily, weekly, monthly or less, never, or unknown (secondary exposure). Neonatal outcomes included low birthweight, small for gestational age, preterm birth, neonatal intensive care unit admission, and infant respiratory support. RESULTS: Of 364,924 infants, 22,624 (6.2%) were exposed to cannabis in utero. After adjustment for potential confounders, including in utero exposure to other substances, in utero exposure to cannabis was associated with greater odds of low birthweight (adjusted odds ratio, 1.20; 95% confidence interval, 1.12-1.28), small for gestational age (adjusted odds ratio, 1.24; 95% confidence interval, 1.18-1.30), preterm birth (<37 weeks; adjusted odds ratio, 1.06; 95% confidence interval, 1.00-1.13), and neonatal intensive care unit admission (adjusted odds ratio, 1.06; 95% confidence interval, 1.01-1.11). There was a suggestive association with early preterm birth (<34 weeks; adjusted odds ratio, 1.11; 95% confidence interval, 1.00-1.23; P=.055), but no significant association with respiratory support (adjusted odds ratio, 1.07; 95% confidence interval, 0.97-1.18). Dose-response analysis found an increasing likelihood of low birthweight and small for gestational age with increasing frequency of prenatal cannabis use by the pregnant individual. Sensitivity analyses further supported an increased likelihood of low birthweight and small for gestational age, although associations with other outcomes did not reach statistical significance. CONCLUSION: In utero cannabis exposure was associated with increased likelihood of low birthweight, small for gestational age, preterm birth, and neonatal intensive care unit admission. Clinicians should counsel individuals who are pregnant or considering pregnancy about the potential adverse neonatal health outcomes associated with prenatal cannabis use.
RESUMEN
Objectives. To identify lessons learned from implementation of the nation's first sugar-sweetened beverage (SSB) excise tax in 2015 in Berkeley, California.Methods. We interviewed city stakeholders and SSB distributors and retailers (n = 48) from June 2015 to April 2017 and analyzed records through January 2019.Results. Lessons included the importance of thorough and timely communications with distributors and retailers, adequate lead time for implementation, advisory commissions for revenue allocations, and funding of staff, communications, and evaluation before tax collection begins. Early and robust outreach about the tax and programs funded can promote and sustain public support, reduce friction, and facilitate beverage price increases on SSBs only. No retailer reported raising food prices, indicating that Berkeley's SSB tax did not function as a "grocery tax," as industry claimed. Revenue allocations totaled more than $9 million for public health, nutrition, and health equity through 2021.Conclusions. The policy package, context, and implementation process facilitated translating policy into public health outcomes. Further research is needed to understand long-term facilitators and barriers to sustaining public health benefits of Berkeley's tax and how those differ from facilitators and barriers in jurisdictions facing significant industry-funded repeal efforts.

BACKGROUND: Taxes on sugar-sweetened beverages (SSBs) meant to improve health and raise revenue are being adopted, yet evaluation is scarce. This study examines the association of the first penny per ounce SSB excise tax in the United States, in Berkeley, California, with beverage prices, sales, store revenue/consumer spending, and usual beverage intake. METHODS AND FINDINGS: Methods included comparison of pre-taxation (before 1 January 2015) and first-year post-taxation (1 March 2015-29 February 2016) measures of (1) beverage prices at 26 Berkeley stores; (2) point-of-sale scanner data on 15.5 million checkouts for beverage prices, sales, and store revenue for two supermarket chains covering three Berkeley and six control non-Berkeley large supermarkets in adjacent cities; and (3) a representative telephone survey (17.4% cooperation rate) of 957 adult Berkeley residents. Key hypotheses were that (1) the tax would be passed through to the prices of taxed beverages among the chain stores in which Berkeley implemented the tax in 2015; (2) sales of taxed beverages would decline, and sales of untaxed beverages would rise, in Berkeley stores more than in comparison non-Berkeley stores; (3) consumer spending per transaction (checkout episode) would not increase in Berkeley stores; and (4) self-reported consumption of taxed beverages would decline. Main outcomes and measures included changes in inflation-adjusted prices (cents/ounce), beverage sales (ounces), consumers' spending measured as store revenue (inflation-adjusted dollars per transaction) in two large chains, and usual beverage intake (grams/day and kilocalories/day). Tax pass-through (changes in the price after imposition of the tax) for SSBs varied in degree and timing by store type and beverage type. Pass-through was complete in large chain supermarkets (+1.07¢/oz, p = 0.001) and small chain supermarkets and chain gas stations (1.31¢/oz, p = 0.004), partial in pharmacies (+0.45¢/oz, p = 0.03), and negative in independent corner stores and independent gas stations (-0.64¢/oz, p = 0.004). Sales-unweighted mean price change from scanner data was +0.67¢/oz (p = 0.00) (sales-weighted, +0.65¢/oz, p = 0.003), with +1.09¢/oz (p < 0.001) for sodas and energy drinks, but a lower change in other categories. Post-tax year 1 scanner data SSB sales (ounces/transaction) in Berkeley stores declined 9.6% (p < 0.001) compared to estimates if the tax were not in place, but rose 6.9% (p < 0.001) for non-Berkeley stores. Sales of untaxed beverages in Berkeley stores rose by 3.5% versus 0.5% (both p < 0.001) for non-Berkeley stores. Overall beverage sales also rose across stores. In Berkeley, sales of water rose by 15.6% (p < 0.001) (exceeding the decline in SSB sales in ounces); untaxed fruit, vegetable, and tea drinks, by 4.37% (p < 0.001); and plain milk, by 0.63% (p = 0.01). Scanner data mean store revenue/consumer spending (dollars per transaction) fell 18¢ less in Berkeley (-$0.36, p < 0.001) than in comparison stores (-$0.54, p < 0.001). Baseline and post-tax Berkeley SSB sales and usual dietary intake were markedly low compared to national levels (at baseline, National Health and Nutrition Examination Survey SSB intake nationally was 131 kcal/d and in Berkeley was 45 kcal/d). Reductions in self-reported mean daily SSB intake in grams (-19.8%, p = 0.49) and in mean per capita SSB caloric intake (-13.3%, p = 0.56) from baseline to post-tax were not statistically significant. Limitations of the study include inability to establish causal links due to observational design, and the absence of health outcomes. Analysis of consumption was limited by the small effect size in relation to high standard error and Berkeley's low baseline consumption. CONCLUSIONS: One year following implementation of the nation's first large SSB tax, prices of SSBs increased in many, but not all, settings, SSB sales declined, and sales of untaxed beverages (especially water) and overall study beverages rose in Berkeley; overall consumer spending per transaction in the stores studied did not rise. Price increases for SSBs in two distinct data sources, their timing, and the patterns of change in taxed and untaxed beverage sales suggest that the observed changes may be attributable to the tax. Post-tax self-reported SSB intake did not change significantly compared to baseline. Significant declines in SSB sales, even in this relatively affluent community, accompanied by revenue used for prevention suggest promise for this policy. Evaluation of taxation in jurisdictions with more typical SSB consumption, with controls, is needed to assess broader dietary and potential health impacts.

OBJECTIVES: We estimated sodium intake, which is associated with elevated blood pressure, a major risk factor for cardiovascular disease, and assessed its association with related variables among New York City adults. METHODS: In 2010 we conducted a cross-sectional, population-based survey of 1656 adults, the Heart Follow-Up Study, that collected self-reported health information, measured blood pressure, and obtained sodium, potassium, and creatinine values from 24-hour urine collections. RESULTS: Mean daily sodium intake was 3239 milligrams per day; 81% of participants exceeded their recommended limit. Sodium intake was higher in non-Hispanic Blacks (3477 mg/d) and Hispanics (3395 mg/d) than in non-Hispanic Whites (3066 mg/d; both P < .05). Higher sodium intake was associated with higher blood pressure in adjusted models, and this association varied by race/ethnicity. CONCLUSIONS: Higher sodium intake among non-Hispanic Blacks and Hispanics than among Whites was not previously documented in population surveys relying on self-report. These results demonstrate the feasibility of 24-hour urine collection for the purposes of research, surveillance, and program evaluation.

In 2006, the New York City Department of Health and Mental Hygiene, seeking to address the epidemic of childhood obesity, issued new regulations on beverages, physical activity, and screen time in group child care centers. An evaluation was conducted to identify characteristics of New York City child care centers that have implemented these regulations and to examine how varying degrees of implementation affected children's behaviors. This article discusses results of this evaluation and how findings can be useful for other public health agencies. Knowing the characteristics of centers that are more likely to comply can help other jurisdictions identify centers that may need additional support and training. Results indicated that compliance may improve when rules established by governing agencies, national standards, and local regulatory bodies are complementary or additive. Therefore, the establishment of clear standards for obesity prevention for child care providers can be a significant public health achievement.

Childhood obesity is associated with health risks in childhood, and it increases the risk of adult obesity, which is associated with many chronic diseases. Therefore, implementing policies that may prevent obesity at young ages is important. In 2007, the New York City Department of Health and Mental Hygiene implemented new regulations for early childhood centers to increase physical activity, limit screen time, and provide healthful beverage offerings (ie, restrict sugar-sweetened beverages for all children, restrict whole milk for those older than 2 years, restrict juice to beverages that are 100% juice and limit serving of juice to only 6 ounces per day, and make water available and accessible at all times). This article explains why these amendments to the Health Code were created, how information about these changes was disseminated, and what training programs were used to help ensure implementation, particularly in high-need neighborhoods.

BACKGROUND: Policies governing legal cannabis commerce can vary widely within a U.S. state when local control exists. Disproportionate distribution of policies allowing retail sale, protecting public health, or promoting equity in licensing may contribute to differences in health and economic outcomes between sociodemographic subgroups. This cross-sectional study jointly examined racial, ethnic, and neighborhood socioeconomic characteristics of Californians subject to specific local cannabis policies to identify such disparities. METHODS: Local laws in effect January 1, 2020, governing retail cannabis sales (bans, expanding buffers from youth-serving sites, restricting advertising, promoting equity in licensing, and capping outlets) were determined for California's 539 jurisdictions. The number of Asian, Black, Latinx, and white residents in socioeconomic advantaged versus disadvantaged neighborhoods (Census block groups) was determined using 2015-2019 American Community Survey data. We estimated proportions of the sociodemographic subpopulations covered by specific policies based on the block group's jurisdiction. To ascertain disparities in coverage proportions were compared across subgroups using Z-tests with the Bonferroni correction. RESULTS: Residents of socioeconomically advantaged neighborhoods were more likely to live in jurisdictions allowing retail cannabis commerce than those in disadvantaged neighborhoods (61.7 % versus 54.8 %). Black residents in advantaged neighborhoods were most likely to live where retailing was allowed (69 %), and white residents in disadvantaged neighborhoods least likely (49 %). Latinx and Black populations from disadvantaged neighborhoods were most likely to live in jurisdictions with stronger advertising restrictions (66 %). Equity in licensing policy was more prevalent for Black residents living in advantaged neighborhoods (57 %) than disadvantaged neighborhoods (49 %). CONCLUSIONS: Local cannabis policies potentially protecting public health and social equity are unequally distributed across race, ethnicity, and socioeconomic characteristics in California. Research examining whether differential policy exposure reduces, creates, or perpetuates cannabis-related health and socioeconomic disparities is needed.
RESUMEN
BACKGROUND: As more states legalize cannabis, studies are needed to understand the potential impacts of recreational cannabis legalization (RCL) on adolescents from the perspective of clinicians who care for them. METHODS: This qualitative study characterized clinician perspectives on whether cannabis legalization is associated with changes in adolescents' cannabis use beliefs, behaviors, and consequences. Semi-structured qualitative interviews were conducted with 32 clinicians in a large healthcare organization from 9/6/2022-12/21/2022. Video-recorded interviews were transcribed and analyzed using thematic analysis. RESULTS: The 32 participants (56.3â¯% female, mean [SD] age, 45.9 [7.6] years; 65.3â¯% non-Hispanic White) were from Addiction Medicine (nâ¯=â¯13), Psychiatry/Mental Health (nâ¯=â¯7), Pediatrics (nâ¯=â¯5), and the Emergency Department (nâ¯=â¯7). Clinicians described post-RCL increases in adolescent cannabis use, use of non-combustible modes and high-potency products, and younger age of first use. Clinicians reported social, physical, and policy changes, including changes in social norms, appealing advertisements, marketing, and easier access. Many noted fewer perceived harms among adolescents and greater self-medication post-RCL. They described how RCL contributed to increased parental cannabis use and permissiveness around adolescent use. Finally, many described post-RCL increases in cannabis hyperemesis syndrome, and several noted increased cannabis-related psychosis and acute intoxication, and decreased court-mandated treatment. CONCLUSIONS: Clinicians from diverse specialties described post-RCL increases in adolescent cannabis use and cannabis-related consequences, alongside changes in social norms, access, marketing and advertisements, and decreased perceptions of harms. Findings can inform strategies to support adolescents in the context of increased cannabis availability and acceptability post-legalization and support the development of hypotheses for broader-scale quantitative work.

Importance: Many studies have evaluated whether in utero cannabis exposure is associated with fetal and neonatal outcomes, yet little is known about whether prenatal cannabis use is associated with maternal health outcomes during pregnancy. Objective: To evaluate whether prenatal cannabis use is associated with maternal health outcomes during pregnancy. Design, Setting, and Participants: This population-based retrospective cohort study included pregnancies in Northern California from January 2011 to December 2019 that lasted 20 weeks or longer and were screened for prenatal cannabis use. Exposures: Prenatal cannabis use was defined as any self-reported use during early pregnancy or a positive toxicology test result based on universal screening at entrance to prenatal care (approximately 8-10 weeks' gestation). Self-reported frequency of use (daily, weekly, monthly or less, never, unknown), use defined only by self-report, and use defined only by toxicology test results were examined. Main Outcomes and Measures: Electronic health record data were used to define the following outcomes: gestational hypertension, preeclampsia, eclampsia, gestational diabetes, gestational weight gain greater and less than guidelines, placenta previa, placental abruption, placenta accreta, and severe maternal morbidity. Adjusted risk ratios (aRRs) were calculated using a modified Poisson regression. Results: The sample (n = 316â¯722 pregnancies; 250â¯221 unique individuals) included 84â¯039 (26.5%) Asian/Pacific Islander, 20â¯053 (6.3%) Black, 83â¯145 (26.3%) Hispanic, and 118â¯333 (37.4%) White individuals; the mean (SD) age was 30.6 (5.4) years. Overall, 20â¯053 (6.3%) screened positive for prenatal cannabis use; 2.9% were positive by self-report, 5.3% by toxicology testing, and 1.8% by both. The frequency of cannabis use was 1930 (0.6%) daily, 2345 (0.7%) weekly, 4892 (1.5%) monthly or less, and 10â¯886 (3.4%) unknown. Prenatal cannabis use was associated with greater risk of gestational hypertension (aRR, 1.17; 95% CI, 1.13-1.21), preeclampsia (aRR, 1.08; 95% CI, 1.01-1.15), weight gain less than (aRR, 1.05; 95% CI, 1.01-1.08) and greater than (aRR, 1.09; 95% CI, 1.08-1.10) guidelines, and placental abruption (aRR, 1.19; 95% CI, 1.05-1.36). The pattern of results was similar when defining prenatal cannabis use only by self-report or only by toxicology testing, and associations between the frequency of prenatal cannabis use and outcomes varied with outcome. Conclusions and Relevance: The results of this cohort study suggest that prenatal cannabis use was associated with several adverse maternal health outcomes during pregnancy. Continued research is needed to understand whether characteristics of prenatal cannabis use (eg, dose, mode, and timing) moderate these associations.
RESUMEN
BACKGROUND: Dietary trans fat increases risk for coronary heart disease. In 2006, New York City (NYC) passed the first regulation in the United States restricting trans fat use in restaurants. OBJECTIVE: To assess the effect of the NYC regulation on the trans and saturated fat content of fast-food purchases. DESIGN: Cross-sectional study that included purchase receipts matched to available nutritional information and brief surveys of adult lunchtime restaurant customers conducted in 2007 and 2009, before and after implementation of the regulation. SETTING: 168 randomly selected NYC restaurant locations of 11 fast-food chains. PARTICIPANTS: Adult restaurant customers interviewed in 2007 and 2009. MEASUREMENTS: Change in mean grams of trans fat, saturated fat, trans plus saturated fat, and trans fat per 1000 kcal per purchase, overall and by chain type. RESULTS: The final sample included 6969 purchases in 2007 and 7885 purchases in 2009. Overall, mean trans fat per purchase decreased by 2.4 g (95% CI, -2.8 to -2.0 g; P < 0.001), whereas saturated fat showed a slight increase of 0.55 g (CI, 0.1 to 1.0 g; P = 0.011). Mean trans plus saturated fat content decreased by 1.9 g overall (CI, -2.5 to -1.2 g; P < 0.001). Mean trans fat per 1000 kcal decreased by 2.7 g per 1000 kcal (CI, -3.1 to -2.3 g per 1000 kcal; P < 0.001). Purchases with zero grams of trans fat increased from 32% to 59%. In a multivariate analysis, the poverty rate of the neighborhood in which the restaurant was located was not associated with changes. LIMITATION: Fast-food restaurants that were included may not be representative of all NYC restaurants. CONCLUSION: The introduction of a local restaurant regulation was associated with a substantial and statistically significant decrease in the trans fat content of purchases at fast-food chains, without a commensurate increase in saturated fat. Restaurant patrons from high- and low-poverty neighborhoods benefited equally. However, federal regulation will be necessary to fully eliminate population exposure to industrial trans fat sources.

BACKGROUND: Sugar sweetened beverage (SSB) taxes are a promising strategy to decrease SSB consumption, and their inequitable health impacts, while raising revenue to meet social objectives. In 2016, San Francisco passed a one cent per ounce tax on SSBs. This study compared SSB consumption in San Francisco to that in San José, before and after tax implementation in 2018. METHODS & FINDINGS: A longitudinal panel of adults (n = 1,443) was surveyed from zip codes in San Francisco and San José, CA with higher densities of Black and Latino residents, racial/ethnic groups with higher SSB consumption in California. SSB consumption was measured at baseline (11/17-1/18), one- (11/18-1/19), and two-years (11/19-1/20) after the SSB tax was implemented in January 2018. Average daily SSB consumption (in ounces) was ascertained using the BevQ-15 instrument and modeled as both continuous and binary (high consumption: ≥6 oz (178 ml) versus low consumption: <6 oz) daily beverage intake measures. Weighted generalized linear models (GLMs) estimated difference-in-differences of SSB consumption between cities by including variables for year, city, and their interaction, adjusting for demographics and sampling source. In San Francisco, average SSB consumption in the sample declined by 34.1% (-3.68 oz, p = 0.004) from baseline to 2 years post-tax, versus San José which declined 16.5% by 2 years post-tax (-1.29 oz, p = 0.157), a non-significant difference-in-differences (-17.6%, adjusted AMR = 0.79, p = 0.224). The probability of high SSB intake in San Francisco declined significantly more than in San José from baseline to 2-years post-tax (AOR[interaction] = 0.49, p = 0.031). The difference-in-differences of odds of high consumption, examining the interaction between cities, time and poverty, was far greater (AOR[city*year 2*federal poverty level] = 0.12, p = 0.010) among those living below 200% of the federal poverty level 2-years post-tax. CONCLUSIONS: Average SSB intake declined significantly in San Francisco post-tax, but the difference in differences between cities over time did not vary significantly. Likelihood of high SSB intake declined significantly more in San Francisco by year 2 and more so among low-income respondents.
RESUMEN
Introduction: The 2019 outbreak of e-cigarette or vaping product use-associated lung injury (EVALI) is believed to have been caused by vitamin E acetate, an additive used in some cannabis vaporizer products. Previous studies have primarily focused on changes in sales of electronic nicotine delivery systems following the initial advisory issued by the Centers for Disease Control (CDC) on August 17, 2019. The present study is intended to examine variation by age groups in sales of regulated cannabis vape products in the state of California before, during, and after the outbreak. Methods: Weekly sales revenue of cannabis vape products (from January 1, 2018, to December 31, 2020) was obtained from a sample of recreational cannabis retailers licensed in California. An interrupted time series analysis, using AutoRegressive, Integrated, Moving Average methods, was employed to estimate changes in the sales and market share of cannabis vape products in the weeks following the CDC advisory. Results: The total volume of regulated cannabis vape product sales increased substantially over the 3-year study period (2018-2020). Sales and market share of cannabis vape products, however, declined in both young and older adults immediately following the advisory, rebounding to pre-EVALI levels only for the young adults. For sales, the potential EVALI effect following the CDC's advisory equates to an 8.0% and 2.2% decline below expected levels in the older and young adults, respectively. Conclusions: The differential age effect on sales may reflect concerns regarding health effects of cannabis vaping products and greater awareness of the outbreak among older adults. Findings highlight the importance of informing consumers about health risks associated with using cannabis vape products acquired from regulated versus illicit sources.
RESUMEN
OBJECTIVES: We evaluated the effectiveness of the Public Health Detailing Program in helping primary care providers and their staff to improve patient care on public health challenges. METHODS: We analyzed reported changes in clinical practice or behavior by examining providers' retention and implementation of recommendations for campaigns. RESULTS: During each campaign, 170 to 443 providers and 136 to 221 sites were reached. Among assessed providers who indicated changes in their practice behavior, the following statistically significant increases occurred from baseline to follow-up. Reported screening for clinical preventive services increased, including routinely screening for intimate partner violence (14%-42%). Clinical management increased, such as prescribing longer-lasting supplies of medicine (29%-42%). Lifestyle modification and behavior change, such as recommending increased physical activity to patients with high cholesterol levels, rose from 52% to 73%. Self-management goal setting with patients increased, such as using a clinical checkbook to track hemoglobin A1c goals (28% to 43%). CONCLUSIONS: Data suggest that public health detailing can be effective for linking public health agencies and their recommendations to providers and influencing reported changes in clinical practice behavior.

Introduction: As cannabis legalization continues to spread, best regulatory practice remains ill-defined and elusive, exposing the population to potential harms. Methods: We conducted an annual, statewide, cross- sectional survey to assess cannabis-related laws in effect by January 1, 2020, in local California jurisdictions and at the state level and measured adoption of potential best practices. Results: The current laws of all 539 jurisdictions were located; 276 jurisdictions allowed any retail sales (storefront or delivery) covering 58% of the population, an increase of 20 jurisdictions (8%) from year 1 of legalization (2018). Half allowed sales of medical cannabis, whereas slightly fewer jurisdictions (n = 225) allowed adult-use sales. Only 9 jurisdictions imposed any restrictions on products stricter than state regulations. Cannabis temporary special events were allowed in 22 jurisdictions, up from 14 in the year prior. Thirty-three jurisdictions required additional health warnings for consumers. Just over half of legalizing jurisdictions taxed cannabis locally and little revenue was captured for prevention. No new jurisdictions established a potency-linked tax. Of jurisdictions allowing storefront retailers (n = 162), 114 capped outlet licenses, and 49 increased the state-specified buffers between storefronts and schools. Thirty-six allowed on-site consumption, up from 29. As of January 2020, the state had not updated its regulations of key provisions addressed in this paper. Conclusions: In year 2 of legalized adult-use cannabis sales in California, the state remained split between retail bans and legal sale. Local policy continued to vary widely on protective measures, and State policy remained misaligned with protection of youth and public health.
RESUMEN
BACKGROUND: This study experimentally examines whether enhanced cannabis warning labels (CWLs) outperform those currently required in the U.S. in improving recall of health risks, emotional responses, and perceived message effectiveness among at-risk young adults. METHOD: We conducted an online national survey-based experiment in October 2020. Young adults aged 18-26 years old and at-risk for cannabis use (N = 523) were randomly assigned in an online experiment, to view either currently required CWLs in California with small font and a composite health risk statement, or enhanced single-theme CWLs with varying textual and pictorial components. We performed linear regression analyses to compare the enhanced with existing CWLs on information recall, negative emotions, and perceived message effectiveness. Furthermore, information recall and negative emotions were examined as parallel mediators to better understand the mechanisms underlying effective textual and pictorial enhancement of CWLs. RESULTS: Compared with currently required CWLs in California, both textually (b = 0.30, p = .011) and pictorially (b = 0.59, p < .001) enhanced CWLs increased recall accuracy. Pictorially enhanced CWLs outperformed their text-only counterparts (b = 0.28, p = .019) in improving information recall. Only pictorially enhanced CWLs improved perceived message effectiveness (b = 0.31, p = .008), which was mediated by negative emotions but not by information recall. CONCLUSIONS: Given rapid expansion of the cannabis industry and declining perception of harm, currently required CWLs in the U.S. such as California's, would benefit from redesign to improve public understanding of health risks and to prevent youth use.

Importance: Prenatal cannabis use is associated with health risks for mothers and their children. Prior research suggests that rates of prenatal cannabis use in Northern California increased during the COVID-19 pandemic, but it is unknown whether increases varied with the local cannabis retail and policy environment. Objective: To test whether pandemic-related increases in prenatal cannabis use were greater among pregnant individuals with greater retail availability of cannabis around their homes or among those living in jurisdictions that allowed storefront retailers. Design, Setting, and Participants: A cross-sectional, population-based time series study used data from pregnancies in the Kaiser Permanente Northern California health care system screened for cannabis use before (January 1, 2019, to March 31, 2020) and during (April 1 to December 31, 2020) the early COVID-19 pandemic. Proximity to the nearest retailer and number of retailers within a 15-minute drive from one's home and local cannabis storefront retailer policy (banned vs permitted) were calculated. Interrupted time series models were fit using multiplicative and additive Poisson regression, adjusting for age and race and ethnicity. Exposures: The COVID-19 pandemic. Main Outcomes and Measures: Prenatal cannabis use based on universal urine toxicology tests conducted during early pregnancy at entrance to prenatal care. Results: The sample (n = 99â¯127 pregnancies) included 26.2% Asian or Pacific Islander, 6.8% Black, 27.6% Hispanic, 34.4% non-Hispanic White, and 4.9% other, unknown, or multiracial individuals, with a mean (SD) age of 30.8 (5.3) years. Prenatal cannabis use before (6.8%) and during (8.2%) the pandemic was associated with closer proximity to a retailer, greater retailer density, and residing in a jurisdiction that permitted vs banned retailers. There was a greater absolute increase in cannabis use from before to during the pandemic among those within a 10-minute drive (<10 minutes: adjusted rate difference [aRD], 0.93 cases/100 patients; 95% CI, 0.56-1.29 cases/100 patients; ≥10 minutes: aRD, 0.40 cases/100 patients; 95% CI, 0.12-0.68 cases/100 patients; interaction P = .02). Otherwise, relative and absolute rates increased similarly across categories of cannabis retailer proximity/density and local policy (interaction P > .05). Conclusions and Relevance: Prenatal cannabis use was more common among individuals living in areas with greater retail availability of cannabis. Although relative rates increased similarly during the pandemic regardless of local cannabis retail and policy environment, there was a larger absolute increase associated with living closer to a storefront cannabis retailer. Continued monitoring of local cannabis policy, the retail environment, and prenatal cannabis use is needed.

BACKGROUND: Recent changes in California's tobacco and cannabis policies could impact the retail availability of little cigars/cigarillos (LCCs) and blunt wraps that are used for blunt smoking. This study was intended to test whether tobacco flavor bans and minimum pack sizes of LCCs have reduced tobacco availability in California jurisdictions, whereas, permissive policies on sales and marketing of cannabis increased availability. METHODS: Measures of retail availability of LCCs and blunt wraps were obtained from the 2016-2019 longitudinal sample of licensed tobacco retailers (LTRs, n = 4062) from California's Healthy Stores for Healthy Communities campaign. Additional data sources included the California Cannabis Local Laws database and geographic location of 1063 cannabis retailers used for constructing a spatial index of accessibility to the LTRs. Two-level generalized structural equation models were developed to assess effects of store- and jurisdiction-level predictors of change in tobacco availability (+, -, no change). RESULTS: Neither permissive cannabis policies nor accessibility to cannabis retailers were associated with an increase in retail availability of the tobacco products. Enactment of a tobacco flavor ban, however, was associated with reduced availability of LCCs and blunt wraps, which was more pronounced in jurisdictions that had permissive cannabis policies (i.e. policy interaction). CONCLUSIONS: A tobacco flavor ban may be an effective strategy to reduce retail availability of LCCs, blunt wraps and possibly other tobacco in California jurisdictions. This finding is of particular relevance as the tobacco industry has successfully petitioned for a referendum vote on California's statewide flavor ban in the 2022 election.

OBJECTIVES: We assessed consumer awareness of menu calorie information at fast-food chains after the introduction of New York City's health code regulation requiring these chains to display food-item calories on menus and menu boards. METHODS: At 45 restaurants representing the 15 largest fast-food chains in the city, we conducted cross-sectional surveys 3 months before and 3 months after enforcement began. At both time points, customers were asked if they had seen calorie information and, if so, whether it had affected their purchase. Data were weighted to the number of city locations for each chain. RESULTS: We collected 1188 surveys pre-enforcement and 1229 surveys postenforcement. Before enforcement, 25% of customers reported seeing calorie information; postenforcement, this figure rose to 64% (P < .001; 38% and 72%, weighted). Among customers who saw calorie information postenforcement, 27% said they used the information, which represents a 2-fold increase in the percentage of customers making calorie-informed choices (10% vs 20%, weighted; P < .001). CONCLUSIONS: Posting calorie information on menu boards increases the number of people who see and use this information. Since enforcement of New York's calorie labeling regulation began, approximately 1 million New York adults have seen calorie information each day.
