Flavored E-Cigarette Sales Restrictions and Young Adult Tobacco Use.

Importance: More than one-quarter of US residents live in states or localities that restrict sales of flavored electronic nicotine delivery systems (ENDS), often as a means to reduce youth vaping. Yet, how these policies affect young adult vaping and smoking remains unclear.

Objective: To estimate the effects of ENDS flavor restrictions on ENDS use and cigarette smoking among young adults (age 18-29 years) in the US.

Standardising the measurement of e-cigarette tax rates in the USA (2nd edition), 2010-2023.

Introduction: 30 states enacted e-cigarette taxes by the end of 2023. E-cigarette tax schema in the USA vary, in contrast to cigarette taxes that are standardised as an excise tax amount per pack. Some states use excise taxes on liquid and containers, others wholesale sales taxes and others retail sales taxes.

The Effect of E-Cigarette Indoor Vaping Restrictions on Infant Mortality.

We estimate the effect of county-level e-cigarette indoor vaping restrictions (IVRs) on infant mortality using United States birth certificates from 2010 to 2015. We estimate difference-in-differences models and find that e-cigarette indoor vaping restrictions increased infant mortality by 0.39 infants per 1,000 live births (12.

The effect of vertical identification card laws on teenage tobacco and alcohol use.

We study the impact of vertical identification card laws, which changed the orientation of driver's licenses and state identification cards from horizontal to vertical for those under 21 years, on teenage tobacco and alcohol use. We study this question using four national datasets (pooled national and state Youth Risk Behavior Surveillance System, National Youth Tobacco Survey, Current Population Survey to Tobacco Use Supplements, and Behavioral Risk Factor Surveillance System). We improve previous databases of vertical ID law implementation by using original archival research to identify the exact date of the law change.

Electronic cigarettes and subsequent use of cigarettes in young people: An evidence and gap map.

Background And Aims: The use of e-cigarettes may influence later smoking uptake in young people. Evidence and gap maps (EGMs) are interactive on-line tools that display the evidence and gaps in a specific area of policy or research. The aim of this study was to map clusters and gaps in evidence exploring the relationship between e-cigarette use or availability and subsequent combustible tobacco use in people aged < 30 years.

Coverage of Indoor Smoking and Vaping Restrictions in the U.S., 1990-2021.

Introduction: Secondhand smoke exposure increases the risk of premature death and disease in children and non-smoking adults. As a result, many U.S.

Longitudinal Policy Surveillance of Private Insurance Hearing Aid Mandates in the United States: 1997-2022.

To produce a database of private insurance hearing aid mandates in the United States and quantify the share of privately insured individuals covered by a mandate. We used health-related policy surveillance methods to create a database of private insurance hearing aid mandates through January 2023. We coded salient features of mandates and combined policy data with American Community Survey and Medicare Expenditure Panel Survey-Insurance Component data to estimate the share of privately insured US residents covered by a mandate from 2008 to 2022.

Ambulatory Care Fragmentation and Total Health Care Costs.

Background: The magnitude of the relationship between ambulatory care fragmentation and subsequent total health care costs is unclear.

Objective: To determine the association between ambulatory care fragmentation and total health care costs.

Research Design: Longitudinal analysis of 15 years of data (2004-2018) from the national Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, linked to Medicare fee-for-service claims.

Estimating the effects of tobacco-21 on youth tobacco use and sales.

We examine the effect of raising the minimum legal sale age of tobacco to 21 (i.e., "T21").

The effect of e-cigarette taxes on prepregnancy and prenatal smoking.

E-cigarette taxes are an active area of legislation and have important regulatory implications by proxying e-cigarette accessibility. We examine the effect of e-cigarette taxes on prepregnancy and prenatal smoking using the near-universe of births to mothers conceiving between 2013 and 2019 in the United States. Using fixed effect regressions, we show that e-cigarette taxes increase prepregnancy and prenatal smoking.

Tobacco 21 Laws and Youth Tobacco Use: The Role of Policy Attributes.

To estimate Tobacco-21 policies' relationships to 18- to 20 year-old youth cigarette, cigar, and electronic nicotine delivery system (ENDS) use, and to test for effect modification by policy attributes. In fall 2022, we used Tobacco 21 Population Coverage Database data to calculate the percentage of state residents covered by state or local Tobacco 21 (T21) laws monthly through June 2020. Matching T21 coverage to Population Assessment of Tobacco and Health and Behavioral Risk Factor Surveillance System data, we used 2-way fixed effect analyses to assess the relationship between T21 laws and 18- to 20-year-old youth cigarette, cigar, and ENDS use, and tested for differences by policy attributes: possession, use, or purchase (PUP) penalties, retailer noncompliance penalties, and compliance check requirements.

Effect of e-cigarette taxes on e-cigarette and cigarette retail prices and sales, USA, 2014-2019.

Objective: To use a standardised e-cigarette tax measure to examine the impact of e-cigarette taxes on the price and sales of e-cigarettes and cigarettes in the USA.

Design: We used State Line versions of NielsenIQ Retail Scanner data from quarter 4 of 2014 through quarter 4 of 2019 to calculate e-cigarette and cigarette prices and sales in 23 US states. We then estimated how these outcomes are associated with standardised state-level e-cigarette taxes, controlling for state fixed effects, quarter-by-year fixed effects, cigarette taxes, other tobacco control policies and other state-level time-varying characteristics.

MRTP claim authorisation and General Snus sales in the USA: evidence from a difference-in-differences model.

Background: The 2009 Tobacco Control Act granted the US Food and Drug Administration (FDA) regulatory authority over tobacco products, including the ability to authorise modified-risk tobacco product (MRTP) claims. In October 2019, the FDA authorised the first-ever MRTP claim for General Snus, which allowed the product to be marketed as reduced risk (relative to cigarettes). MRTP authorisation may increase otherwise low rates of snus use in the USA (<0.

State Medicaid and private telemedicine coverage requirements and telemedicine use, 2013-2019.

Objective: To examine the association between state Medicaid and private telemedicine coverage requirements and telemedicine use. A secondary objective was to examine whether these policies were associated with health care access.

Data Sources And Study Setting: We used nationally representative survey data from the 2013-2019 Association of American Medical Colleges Consumer Survey of Health Care Access.

Have recreational marijuana laws undermined public health progress on adult tobacco use?

Public health experts caution that legalization of recreational marijuana may normalize smoking and undermine the decades-long achievements of tobacco control policy. However, very little is known about the impact of recreational marijuana laws (RMLs) on adult tobacco use. Using newly available data from the Population Assessment of Tobacco and Health (PATH) and dynamic difference-in-differences and discrete-time hazard approaches, we find that RML adoption increases prior-month marijuana use among adults ages 18-and-older by 2-percentage-points, driven by an increase in marijuana initiation among prior non-users.

The effects of contemporaneous air pollution on COVID-19 morbidity and mortality.

We examine the relationship between contemporaneous fine particulate matter exposure and COVID-19 morbidity and mortality using an instrumental variable approach. Harnessing daily changes in county-level wind direction, we show that arguably exogenous fluctuations in local air quality impact the incidence of confirmed COVID-19 cases and deaths. We find that a one g/m increase in PM 2.

Does paid sick leave encourage staying at home? Evidence from the United States during a pandemic.

We study the impact of a temporary U.S. paid sick leave mandate that became effective April 1st, 2020 on self-quarantining, proxied by physical mobility behaviors gleaned from cellular devices.

Cancer Screening after the Adoption of Paid-Sick-Leave Mandates.

Background: By the end of 2022, nearly 20 million workers in the United States have gained paid-sick-leave coverage from mandates that require employers to provide benefits to qualified workers, including paid time off for the use of preventive services. Although the lack of paid-sick-leave coverage may hinder access to preventive care, current evidence is insufficient to draw meaningful conclusions about its relationship to cancer screening.

Methods: We examined the association between paid-sick-leave mandates and screening for breast and colorectal cancers by comparing changes in 12- and 24-month rates of colorectal-cancer screening and mammography between workers residing in metropolitan statistical areas (MSAs) that have been affected by paid-sick-leave mandates (exposed MSAs) and workers residing in unexposed MSAs.

Medicaid reimbursement rates for primary care services and behavioral health outcomes.

We study the effects of changing Medicaid reimbursement rates for primary care services on behavioral health outcomes-defined here as mental illness and substance use disorders. Medicaid enrollees are at elevated risk for these, and other, chronic conditions and are likely to have unmet treatment needs. We apply two-way fixed-effects regressions to survey data specifically designed to measure behavioral health outcomes over the period 2010-2016.

Intended and unintended effects of e-cigarette taxes on youth tobacco use.

Over the past decade, rising youth use of e-cigarettes and other electronic nicotine delivery systems (ENDS) has contributed to aggressive regulation by state and local governments. Between 2010 and mid-2019, ten states and two large counties adopted ENDS taxes. We use two large national surveys (Monitoring the Future and the Youth Risk Behavior Surveillance System) to estimate the impact of ENDS taxes on youth tobacco use.

The effect of cigarette and e-cigarette taxes on prescriptions for smoking cessation medications.

Objective: To test the effect of cigarette and e-cigarette taxes on prescriptions for smoking cessation medications.

Data Source: Symphony Health, IDV all-payer prescription claims data for the United States over the period 2009-2017. Prescription fills for smoking cessation products were provided at the patient's age, patient's sex, brand/generic, payment type, year, and quarter levels.

The effects of e-cigarette taxes on e-cigarette prices and tobacco product sales: Evidence from retail panel data.

We estimate the effect of e-cigarette tax rates on e-cigarette prices, e-cigarette sales, and sales of other tobacco products using NielsenIQ Retail Scanner data from 2013 to 2019. We find that 90% of e-cigarette taxes are passed on to consumer retail prices. We then estimate reduced form and instrumental variables regressions to examine the effects of e-cigarette and cigarette taxes and prices on sales.
