Data envelopment analysis to evaluate the efficiency of tobacco treatment programs in the NCI Moonshot Cancer Center Cessation Initiative.

BACKGROUND: The Cancer Center Cessation Initiative (C3I) is a National Cancer Institute (NCI) Cancer Moonshot Program that supports NCI-designated cancer centers developing tobacco treatment programs for oncology patients who smoke. C3I-funded centers implement evidence-based programs that offer various smoking cessation treatment components (e.g., counseling, Quitline referrals, access to medications). While evaluation of implementation outcomes in C3I is guided by evaluation of reach and effectiveness (via RE-AIM), little is known about technical efficiency-i.e., how inputs (e.g., program costs, staff time) influence implementation outcomes (e.g., reach, effectiveness). This study demonstrates the application of data envelopment analysis (DEA) as an implementation science tool to evaluate technical efficiency of C3I programs and advance prioritization of implementation resources. METHODS: DEA is a linear programming technique widely used in economics and engineering for assessing relative performance of production units. Using data from 16 C3I-funded centers reported in 2020, we applied input-oriented DEA to model technical efficiency (i.e., proportion of observed outcomes to benchmarked outcomes for given input levels). The primary models used the constant returns-to-scale specification and featured cost-per-participant, total full-time equivalent (FTE) effort, and tobacco treatment specialist effort as model inputs and reach and effectiveness (quit rates) as outcomes. RESULTS: In the DEA model featuring cost-per-participant (input) and reach/effectiveness (outcomes), average constant returns-to-scale technical efficiency was 25.66 (SD = 24.56). When stratified by program characteristics, technical efficiency was higher among programs in cohort 1 (M = 29.15, SD = 28.65, n = 11) vs. cohort 2 (M = 17.99, SD = 10.16, n = 5), with point-of-care (M = 33.90, SD = 28.63, n = 9) vs. no point-of-care services (M = 15.59, SD = 14.31, n = 7), larger (M = 33.63, SD = 30.38, n = 8) vs. smaller center size (M = 17.70, SD = 15.00, n = 8), and higher (M = 29.65, SD = 30.99, n = 8) vs. lower smoking prevalence (M = 21.67, SD = 17.21, n = 8). CONCLUSION: Most C3I programs assessed were technically inefficient relative to the most efficient center benchmark and may be improved by optimizing the use of inputs (e.g., cost-per-participant) relative to program outcomes (e.g., reach, effectiveness). This study demonstrates the appropriateness and feasibility of using DEA to evaluate the relative performance of evidence-based programs.

Developing a Collaborative, Team-Based Smoking Cessation Treatment Program in an Outpatient Oncology Setting.

PURPOSE: Because clinical specialists often lack time and training to address secondary health issues such as smoking cessation, the National Cancer Institute Cancer Center Cessation Initiative (C3I) has mobilized cancer centers to develop systems for treating patients' tobacco dependence. METHODS: One university-based cancer center was able to develop a program that formalized smoking treatment using a collaborative, multidisciplinary care team with overlapping expertise in cancer care, medication management, and tobacco cessation. Program planners delivered tobacco cessation services in the outpatient setting by automating identification of eligible patients using a tobacco registry in the electronic health records, directly involving oncology pharmacists in medication oversight, using dedicated tobacco treatment specialists to provide cessation services, and engaging oncologists through active communications protocols. Evaluators used Practical Robust Implementation and Sustainability Model as the guiding framework for a qualitative assessment of program development and implementation. Evaluators also measured provider satisfaction and utilization of services, program reach, and smoking cessation outcomes 6 months post enrollment. RESULTS: During the evaluation period (July 1, 2018-September 30, 2019), the smoking cessation program engaged 96% of eligible patients (n = 214 of 223 eligible); 82% of those enrolled in the program (n = 183). At 6-month follow-up, 29.1% of enrolled patients self-reported 30-day point prevalence abstinence (n = 53) and 34.9% (n = 64) reported 7-day point prevalence abstinence (intent-to-treat rates). CONCLUSION: Using a team-based approach that leverages individual expertise and interprofessional collaboration to provide patient-centered treatment, a smoking cessation program can identify and treat eligible patients in specialty clinics.

A cross-sectional national survey to explore the relationship between smoking and political abstention: Evidence of social mistrust as a mediator.

RATIONALE: Smoking prevalence is well known to vary socioeconomically but has been less studied in relation to political participation. Growing evidence suggests that health disparities and political nonparticipation are intertwined, but the underlying mechanism is unclear. OBJECTIVE: We investigated the relationship between smoking and voter registration, testing various forms of trust as possible mediators, in U.S. national survey data collected around the 2012 presidential election. METHODS: A random half (n = 9757) of adults who completed The Attitudes and Behaviors Survey on Health (TABS) in 2012 (response rate was 58.4% for landline and 24.3% for cell phone) also answered a section on voter registration, voting behavior, and trust in people and selected institutions. Multivariable logistic regression was used to examine the association between smoking and registering to vote and potential mediation by trust in people and various institutions, adjusted for covariates known to be associated with both. Analyses used design-based methods with weights to account for sampling probabilities, nonresponse, and calibration to the U.S. adult population in 2012. RESULTS: Compared with nonsmokers, daily smokers had significantly lower adjusted odds of being registered to vote (aOR: 0.33, 95% CI: 0.21-0.52) and higher adjusted odds of having low trust in people (aOR: 2.50, 95% CI: 1.29-4.83). Low trust in people predicted lower odds of registering to vote (aOR: 0.55, 95% CI: 0.36 to 0.84) and partially mediated the smoking-registration relationship. CONCLUSION: Lower electoral participation among daily smokers is partly attributable to lower trust in people, a factor that could also affect willingness to use cessation support resources such as quitlines. Low trust and low political participation among daily smokers may have important political and public health consequences.

Mixed-methods economic evaluation of the implementation of tobacco treatment programs in National Cancer Institute-designated cancer centers.

BACKGROUND: The Cancer Center Cessation Initiative (C3I) was launched in 2017 as a part of the NCI Cancer Moonshot program to assist NCI-designated cancer centers in developing tobacco treatment programs for oncology patients. Participating centers have implemented varied evidence-based programs that fit their institutional resources and needs, offering a wide range of services including in-person and telephone-based counseling, point of care, interactive voice response systems, referral to the quitline, text- and web-based services, and medications. METHODS: We used a mixed methods comparative case study design to evaluate system-level implementation costs across 15 C3I-funded cancer centers that reported for at least one 6-month period between July 2018 and June 2020. We analyzed operating costs by resource category (e.g., personnel, medications) concurrently with transcripts from semi-structured key-informant interviews conducted during site visits. Personnel salary costs were estimated using Bureau of Labor Statistics wage data adjusted for area and occupation, and non-wage benefits. Qualitative findings provided additional information on intangible resources and contextual factors related to implementation costs. RESULTS: Median total monthly operating costs across funded centers were $11,045 (range: $5129-$20,751). The largest median operating cost category was personnel ($10,307; range: $4122-$19,794), with the highest personnel costs attributable to the provision of in-person program services. Monthly (non-zero) cost ranges for other categories were medications ($17-$573), materials ($6-$435), training ($96-$516), technology ($171-$2759), and equipment ($10-$620). Median cost-per-participant was $466 (range: $70-$2093) and cost-per-quit was $2688 (range: $330-$9628), with sites offering different combinations of program components, ranging from individually-delivered in-person counseling only to one program that offered all components. Site interviews provided context for understanding variations in program components and their cost implications. CONCLUSIONS: Among most centers that have progressed in tobacco treatment program implementation, cost-per-quit was modest relative to other prevention interventions. Although select centers have achieved similar average costs by offering program components of various levels of intensity, they have varied widely in program reach and effectiveness. Evaluating implementation costs of such programs alongside reach and effectiveness is necessary to provide decision makers in oncology settings with the important additional information needed to optimize resource allocation when establishing tobacco treatment programs.

A Pilot Study and Ecological Model of Smoking Cues to Inform Mobile Health Strategies for Quitting Among Low-Income Smokers.

One crucial factor that leads to disparities in smoking cessation between groups with higher and lower socioeconomic status is more prevalent socioenvironmental smoking cues in low-income communities. Little is known about how these cues influence socioeconomically disadvantaged smokers in real-world scenarios and how to design interventions, especially mobile phone-based interventions, to counteract the impacts of various types of smoking cues. We interviewed 15 current smokers living in low-income communities and scanned their neighborhoods to explore smoking-related experiences and identify multilevel cues that may trigger them to smoke. Findings suggest four major types of smoking cues influence low-income smokers-internal, habitual, social, and environmental. We propose an ecological model of smoking cues to inform the design of mobile health (mHealth) interventions for smoking cessation. We suggest that user-triggered strategies will be most useful to address internal cues; server-triggered strategies will be most suitable in changing perceived social norms of smoking and routine smoking activities to address social and habitual cues; and context-triggered strategies will be most effective for counteracting environmental cues. The pros and cons of each approach are discussed regarding their cost-effectiveness, the potential to provide personalized assistance, and scale.

Duties When an Anonymous Student Health Survey Finds a Hot Spot of Suicidality.

Public health agencies regularly survey randomly selected anonymous students to track drug use, sexual activities, and other risk behaviors. Students are unidentifiable, but a recent project that included school-level analysis discovered a school with alarmingly prevalent student suicidality. Given confidentiality protocols typical of surveillance, the surveyors were uncertain whether and how to intervene. We searched literature for duties to warn at-risk groups discovered during public health surveillance, but we found no directly applicable guidance or cases. Reasoning by analogy, we conclude that surveyors should contact the school's leaders to call attention to its outlier status, but public warning is unwarranted. However, such an ad hoc decision to issue a warning, even if only to school leaders, raises significant practical, legal and ethical issues. National public health and education associations should produce guidance that clarifies ethical and legal duties owed to schools and students involved in population health-risk surveillance.

Adolescent Health Behaviors in Schools with 4- Versus 5-Day School Weeks.

BACKGROUND: The adoption of a shortened school week from the traditional 5 to 4 days is increasing nationwide. Budgetary and staffing needs are driving the change, yet research on the effects on students is lacking, especially regarding student health. Our study examined student health in 4 vs 5-day schools in Colorado, a state with one of the highest numbers of schools with a 4-day week. METHODS: Data are from a population-based survey of high-school students. Student responses were weighted to school enrollment, and schools were classified by length of the school week. Indicators of health behaviors and outcomes were compared between the two groups, adjusted for student and school characteristics. RESULTS: A 4-day school week was associated with several positive health outcomes (improved student engagement, decreased substance use behaviors, decreased non-school screen time, and increased physical activity) as well as several negative health outcomes (increased bullying, increased sexual activity, decreased sleep, and breakfast consumption). CONCLUSIONS: Our study found mixed health outcomes associated with attending schools with shortened weeks. The findings may be related to longer school days and a non-contact day, but further research is needed.

Asking for Identification and Retail Tobacco Sales to Minors.

BACKGROUND AND OBJECTIVES: A previous single-county study found that retail stores usually asked young-looking tobacco customers to show proof-of-age identification, but a large proportion of illegal tobacco sales to minors occurred after the customers had shown identification proving they were too young to purchase tobacco. We sought to investigate these findings on a larger scale. METHODS: We obtained state reports for federal fiscal years 2017 and 2018 from a federal agency that tracks tobacco sales to supervised minors conducting compliance checks in retail stores. We used descriptive and multivariable logistic regression methods to determine (1) how often stores in 17 states requested identifications, (2) what proportion of violations occurred after identification requests, and (3) if violation rates differed when minors were required versus forbidden to carry identification. RESULTS: Stores asked minors for identification in 79.6% (95% confidence interval: 79.3%-80.8%) of compliance checks (N = 17 276). Violations after identification requests constituted 22.8% (95% confidence interval: 20.0%-25.6%; interstate range, 1.7%-66.2%) of all violations and were nearly 3 times as likely when minors were required to carry identification in compliance checks. Violations were 42% more likely when minors asked for a vaping product versus cigarettes. CONCLUSIONS: Stores that sell tobacco to underage customers are more likely to be detected and penalized when youth inspectors carry identification during undercover tobacco sales compliance checks. The new age-21 tobacco sales requirement presents an opportunity to require identifications be carried and address other long-standing weaknesses in compliance-check protocols to help combat the current adolescent vaping epidemic.

Convenience and corner store fruit and vegetable access: attitudes and intentions among Colorado adults, 2014.

Aim: The term food desert generally refers to areas where healthy food options, such as fresh fruits and vegetables, are unavailable within a certain number of miles. However, other factors besides distance may affect the ability to purchase healthier foods. The goal of this study was to understand Colorado adults' perceptions of their access to healthy food options and to assess how other structural and socio-demographic factors may affect that access. Subject and methods: Colorado adults were asked questions about self-reported access to healthy food, likelihood of buying fresh fruits and vegetables from convenience/corner stores if available, perceived characteristics of fruits and vegetables available for purchase near respondents' residence, and demographics. Results: A majority of Colorado adults in 2013-14 reported wanting fresh fruits and vegetables to be more available, more varied, higher quality, and/or less expensive. Socioeconomic status, race/ethnicity, and regular shopping habits were significantly associated with reported likelihood of purchasing fruits and vegetables from a convenience/corner store if available. Conclusion: Factors other than proximity to a grocery store affect Colorado adults' perceived access to healthy food options and should be considered in the development and implementation of public health programs and policies geared toward improving healthy food access.

Association of Marijuana, Mental Health, and Tobacco in Colorado.

OBJECTIVES: Marijuana's evolving legality may change marijuana use patterns in adults. Co-use of marijuana and tobacco are strongly associated, and populations with mental health disorders are disproportionately likely to use either substance, but neither association has been assessed in the context of legal recreational marijuana. We assessed the associations of tobacco smoking with marijuana use and with mental health disorders in Colorado in 2015. METHODS: Data came from a population-based survey of adults (n = 8023). Multiple logistic regressions were used with current tobacco smoking as the primary outcome. Past 30-day marijuana use and mental health status were the independent variables of interest. Covariates included age, sex, ethnicity, poverty level, and education. RESULTS: Adults who used marijuana in the past 30 days had 3.4 (95% confidence interval [CI] 2.7, 4.2) greater odds of currently smoking tobacco compared to adults who had not recently used marijuana, after adjusting for sociodemographic and economic factors. A mental health disorder was independently associated with tobacco smoking (adjusted odds ratio [OR] 1.7, 95% CI 1.4, 2.1). Prevalence of co-use among adults self-reporting a mental health disorder was significantly higher compared those without a mental health disorder (11.1% vs 4.3%; P < 0.0001). CONCLUSIONS: This study examined the associations between mental health, marijuana use, and tobacco smoking after the legalization of recreational marijuana in Colorado. Adults using marijuana and/or self-reporting a mental health disorder were more likely to smoke tobacco and should be targeted for cessation interventions.

Impact of an incentive-based prenatal smoking cessation program for low-income women in Colorado.

OBJECTIVE: To assess birth outcomes and cost-savings of an incentive-based prenatal smoking cessation program targeting low-income women in Colorado. DESIGN: Prospective observational cohort with nonequivalent population control groups. SAMPLE: Program participants (n = 2,231) linked to the birth certificate to ascertain birth outcomes compared to two reference populations from Pregnancy Risk Assessment Monitoring System (PRAMS) and Colorado live births based on the birth certificate. MEASUREMENTS: Tobacco cessation metrics in the third trimester of pregnancy, neonatal low birth weight (<2,500 g), preterm birth (birth at <37 weeks gestation), neonatal intensive care unit (NICU) admission and maternal gestational hypertension. Cost-savings and return on investment (ROI) were projected using average Medicaid reimbursement. RESULTS: Infants of mothers enrolled in the program had a lower risk of low birthweight (RR = 0.86; 95% CI = 0.75, 0.97), preterm birth (PTB) (RR = 0.76; 95% CI = 0.65, 0.88) and neonatal intensive care unit (NICU) admission (RR = 0.76; 95% CI = 0.66, 0.88) compared to the birth certificate population, corresponding to a ROI of $7.73 and an individual cost savings of $6,040. Compared to PRAMS, infants of enrolled mothers had a lower risk of PTB (RR = 0.72; 95% CI = 0.53, 0.99) and NICU admission (RR = 0.45; 95% CI = 0.32, 0.62), corresponding to an ROI of $2.79 and an individual cost savings of $2,182. CONCLUSIONS: We found a reduction of adverse birth outcomes, and cost savings.

Modes of Marijuana Consumption Among Colorado High School Students Before and After the Initiation of Retail Marijuana Sales for Adults.

OBJECTIVE: This study aimed to estimate the prevalence of different modes of marijuana consumption (e.g., smoking, ingesting) overall and by sociodemographic factors, marijuana-related perceptions, and other substance use among adolescents, as well as to characterize differences in the usual mode of consumption before and after the initiation of retail marijuana sales in 2014. METHOD: Data are from the 2013 and 2015 administrations of the Healthy Kids Colorado Survey, a cross-sectional, school-based survey. We included 9th-12th grade students who reported past-30-day marijuana use in 2013 (n = 2,792; 44.8% female) or 2015 (n = 1,664; 48.9% female). We estimated the prevalence of any past-month use of each mode in 2015 and usual mode of consumption the past month in both years. We tested differences by year, sociodemographics, marijuana-related perceptions, and other substance use using Rao-Scott chi-square tests and multivariable logistic regression. RESULTS: The prevalence of past-month marijuana use was 20.7% in both years. In 2015, 39.8% of students reported using multiple modes in the past month. Use of any mode other than smoking and use of multiple modes differed by sociodemographics, marijuana-related perceptions, and other substance use. Smoking remained the most common usual mode in 2015. The prevalence of usually ingesting significantly decreased from 4.7% to 2.1% between years, whereas "other mode(s)" significantly increased from 4.0% to 6.0%. CONCLUSIONS: The use of multiple modes of marijuana consumption was prevalent among adolescents in Colorado. The usual mode of consumption changed in years before and after the implementation of retail marijuana sales, suggesting the need for continued surveillance.

Legalized marijuana: Language-associated knowledge of laws and risk perceptions among Latinos.

This study examines the extent to which knowledge of recreational marijuana laws, health effects, and perceptions of risk for marijuana use differ between Spanish- and English-speaking Latino survey respondents from a registry of Colorado adults. Spanish-speaking Latino respondents (n = 47) had less accurate knowledge of laws permitting use of marijuana than English-speaking Latino respondents (n = 154), while reporting greater agreement with negative health effects and higher perception of risk associated with marijuana use. The results suggest that efforts to communicate health and informational messaging to the public about legalized marijuana should consider linguistic variations when tailoring campaigns for Latino audiences.

Adolescent Marijuana Use, Marijuana-Related Perceptions, and Use of Other Substances Before and After Initiation of Retail Marijuana Sales in Colorado (2013-2015).

Due to the recentness of changes to marijuana policies in a number of states, the effect on adolescent use and perceptions is not yet well understood. This study examines change in adolescent marijuana use and related perceptions in Colorado, before and after the implementation of legal commercial sale of recreational marijuana for adults starting on January 1, 2014. The data are from a repeated cross-sectional survey of a representative sample of Colorado high school students, with separately drawn samples surveyed in fall 2013 (prior to implementation) and fall 2015 (18 months after implementation). We examined change in the prevalence of adolescent marijuana use, measured by lifetime use, past 30-day use, frequent use, and use on school property. To consider the possibility of heterogeneity in the change in marijuana use, we examined change in past 30-day marijuana use by demographic characteristics (sex, grade, race/ethnicity), school characteristics (poverty, percent minority), urbanicity of the school district, and whether the city or county permitted retail marijuana stores. There was an absence of significant effects for change in lifetime or past 30-day marijuana use. Among those reporting past 30-day use, frequent use and use on school property declined. There was a significant decline in the perceived harm associated with marijuana use, but we did not find a significant effect for perceived wrongfulness, perceived ease of access, or perceived parental disapproval. We did not find significant variability in past 30-day use by demographic characteristics or by school and community factors from 2013 to 2015. We did not find a significant effect associated with the introduction of legal sales of recreational marijuana to adults in Colorado on adolescent (illegal) use, but ongoing monitoring is warranted, including consideration of heterogeneity in the effects of marijuana policies.

Assessment of the US Federal Retailer Violation Rate as an Estimate of the Proportion of Retailers That Illegally Sell Tobacco to Adolescents.

Importance: Despite progress against tobacco sales to minors, retailers continue to violate state and federal laws and supply adolescent smokers with tobacco products. Government-sanctioned surveys underestimate the extent of the problem, and retailer associations use these data to block stricter enforcement policies. Objectives: To assess the validity of the US federal retailer violation rate (RVR) as an estimate of the proportion of retailers that sell tobacco to minors and to investigate what proportion always or almost always sells vs refuses to sell cigarettes to minors. Design, Setting, and Participants: This survey study was conducted October 6, 2012, to September 8, 2013; data were analyzed between September 28, 2017, and March 21, 2018. The setting was a suburban county adjacent to Denver, Colorado. Participants were a systematically selected, population-based cluster sample of retailers that stock cigarettes for sale. Retailers were masked to the survey. Main Outcomes and Measures: Each retailer was visited 6 times by supervised minors who attempted to purchase cigarettes at each visit. The main outcome was whether cigarettes were sold. Other measures included whether government-issued photo identification (ID) was requested as required by law, how ID was examined, and what the demographic characteristics of study minors and clerks were. Results: The sample of 201 retailers (44.8% of the 449 listed population) included convenience stores (n = 77), liquor stores (n = 63), grocery stores/supermarkets (n = 33), pharmacies (n = 17), tobacco stores (n = 7), and stand-alone gas stations (n = 4). Bars, clubs, and adult establishments were excluded. A total of 1181 purchase attempts were analyzed; 25 (2.1%) were excluded for missing data. The mean RVR across 6 rounds of checks was 18.0% (95% CI, 14.7%-21.2%) and ranged from 13.7% to 28.0% per round. Most retailers (54.7% [110 of 201]) violated at least once in 6 visits, 26.4% (53 of 201) violated at least twice, and 11.9% (24 of 201) violated half or more times. How retailers examined proof of age largely determined whether violations occurred. Conclusions and Relevance: The proportion of retailers that sold cigarettes to a minor at least once in 6 attempts was 3 times higher than the mean RVR based on a single inspection per retailer. Larger replication studies are needed. Enforcement protocols should reflect the fact that each retailer does not respond consistently when adolescents try to buy tobacco products, and many retailers are not properly validating ID that shows proof of age.

Nicotine Sales to Minors: Store-Level Comparison of E-Cigarette Versus Cigarette Violation Rates.

Introduction: In recent years, e-cigarettes overtook cigarettes as the leading tobacco product used by US adolescents. Most states, as well as federal regulations, have added e-cigarettes to laws prohibiting tobacco products sales to minors. We tested compliance with the newer regulation among Colorado urban retail businesses, speculating that violations might be more common for e-cigarettes than smokable cigarettes. Methods: Supervised minors visited a random sample of urban businesses and sequentially attempted to purchase an e-cigarette product and cigarettes. The protocol prescribed that the same minor make both attempts in each business, separated by at least a day to minimize influence of the first result on the second result. Data were collected during May 2014-January 2015. Results: Among 238 businesses, more than one-fourth (26.1%; 95% confidence interval (CI), 18.9%-33.2%) sold at least one type of product, and 6.3% (CI, 1.8%-10.8%) sold both types. Violation rates were similar for e-cigarette products and cigarettes (17.6% vs. 14.7%, p = n.s.). Conclusion: Enforcement to prevent retail tobacco sales to adolescents should include e-cigarette products. Dual testing of stores indicates that single visits underestimate the problem of underage tobacco sales. Implications: Adolescents can buy e-cigarettes from retail stores as easily as they buy cigarettes. Enforcement of tobacco sales laws should include e-cigarettes, and test-retest protocols are needed to estimate the true extent of the problem.

Adolescent Marijuana Use and Perceived Ease of Access Before and After Recreational Marijuana Implementation in Colorado.

BACKGROUND: As of January 1, 2017, eight states have approved laws for recreational marijuana use. While the social impacts of these changes remain under debate, the influence on adolescent marijuana use is a key policy and health issue across the U.S. OBJECTIVE: To examine changes in adolescent marijuana-use behaviors in the first year after recreational marijuana implementation in Colorado, and to analyze the effect of retail marijuana store proximity on youth use and perceptions. METHOD: Secondary analysis of Healthy Kids Colorado Survey data from 40 schools surveyed before and after recreational marijuana sales were implemented (2013 student n = 12,240; 2014 student n = 11,931). Self-reported marijuana use, ease of access, and perceived harms were compared between years and by proximity of recreational marijuana stores to surveyed schools. RESULTS: Adolescent marijuana use behaviors, wrongness of use, and perceptions of risk of harm were unchanged from baseline to one-year follow-up. Perceived ease of access to marijuana increased (from 46% to 52%). Proximity of recreational marijuana stores was not significantly associated with perceived ease of access to marijuana. Conclusions/Importance: In the first study of adolescent marijuana use and perceptions after state retail implementation of recreational marijuana, there was little change in adolescent marijuana use but a significant change in perception of ease of access. Public health workers and policymakers should continue to monitor these changes as essential for evaluating the impact of liberalization of marijuana policies.

Where the U.S. tobacco epidemic still rages: Most remaining smokers have lower socioeconomic status.

OBJECTIVE: We estimated the proportion of U.S. smokers who have low socioeconomic status (SES). METHODS: We used 2012 data from a national supplement to The Attitudes and Behaviors Survey on Health (TABS), a periodic population survey of Colorado adults. We estimated smoking prevalence and total smokers by education, poverty level, occupation, health insurance status, and combinations of these factors. RESULTS: Smoking prevalence across low-SES categories ranged from 24.3% to 42.6%. Combining low-SES categories with the highest smoking prevalence accounted for 31.1% of U.S. adults but half (50.1%) of smokers. Combining all low-SES categories regardless of smoking prevalence accounted for roughly half (53.3%) of adults but nearly three-fourths (72.2%) of smokers. CONCLUSIONS: A majority of continuing U.S. smokers have low SES. Further progress against the U.S. cigarette epidemic depends on focusing tobacco research and program initiatives on reaching and engaging these smokers in cessation strategies that work for them.
