Cannabis Use During Early Pregnancy Following Recreational Cannabis Legalization.

Importance: It is unknown whether state recreational cannabis legalization (RCL) is related to increased rates of prenatal cannabis use or whether RCL-related changes vary with cannabis screening methods or the local policy environment.

Objective: To test whether RCL in California was associated with changes in prenatal cannabis use rates, whether changes were evident in both self-report and urine toxicology testing, and whether rates varied by local policies banning vs allowing adult-use retailers post-RCL.

Design, Setting, And Participants: This population-based time-series study used data from pregnancies in Kaiser Permanente Northern California universally screened for cannabis use during early pregnancy by self-report and toxicology testing from January 1, 2012, to December 31, 2019.

Cannabis Vape Product Sales in California Following CDC's Initial Advisory About Lung Injuries.

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.

A statewide study of disparities in local policies and tobacco, vape, and cannabis retail environments.

The current study: (1) assesses sociodemographic disparities in local policies related to tobacco and cannabis retail, and (2) examines the cross-sectional association between policy strength and retailer densities of tobacco, e-cigarette (vape), and cannabis retailers within California cities and county unincorporated areas (N = 539). We combined (a) American Community Survey data (2019 5-year estimates), (b) 2018 tobacco, vape, and cannabis retailer locations from a commercial data provider, (c) 2017 tobacco and vape retail environment policy data from American Lung Association, and (d) 2018 cannabis policy data from California Cannabis Local Laws Database. Conditional autoregressive models examined policy strength associations with sociodemographic composition and retailer density in California jurisdictions.

Local Laws Regulating Cannabis in California Two Years Post Legalization: Assessing Incorporation of Lessons from Tobacco Control.

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.

Adolescent use and co-use of tobacco and cannabis in California: The roles of local policy and density of tobacco, vape, and cannabis retailers around schools.

Adolescent tobacco use (particularly vaping) and co-use of cannabis and tobacco have increased, leading some jurisdictions to implement policies intended to reduce youth access to these products; however, their impacts remain unclear. We examine associations between local policy, density of tobacco, vape, and cannabis retailers around schools, and adolescent use and co-use of tobacco/vape and cannabis. We combined 2018 statewide California (US) data on: (a) jurisdiction-level policies related to tobacco and cannabis retail environments, (b) jurisdiction-level sociodemographic composition, (c) retailer locations (tobacco, vape, and cannabis shops), and (d) survey data on 534,176 middle and high school students (California Healthy Kids Survey).

Changes in sugar-sweetened beverage consumption in the first two years (2018 - 2020) of San Francisco's tax: A prospective longitudinal study.

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.

Yet Again Conversations Matter: The Importance of Interpersonal Discussions, Educational Campaigns, and Advertising on Cannabis-Related Risk Perceptions, Attitudes, and Intentions in At-Risk Young Adults.

The present study seeks to evaluate the relationships between cannabis-related communication and outcomes of interest such as cannabis-related risk perceptions, attitudes, and behaviors among young adults. Young adults who were at risk for cannabis use were surveyed online in 2020. Results showed that exposure to online educational messages was associated with higher intentions of engaging in peer intervention, while exposure to online advertising was related to higher intention to use cannabis.

Geographic Accessibility of Retail Cannabis in Northern California and Prenatal Cannabis Use During the COVID-19 Pandemic.

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.

Impact of California's tobacco and cannabis policies on the retail availability of little cigars/cigarillos and blunt wraps.

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.

Objectives: The purpose of this project was to explore the extent to which e-cigarette advertisements use youth-appealing content.

Methods: A sample of e-cigarette video ads (N = 154) were coded by 3 independent coders using the content appealing to youth (CAY) index, which measures over 40 youth-appealing features. To calculate a total CAY score for each ad, scores were normalized and summed such that a higher score represented the presence of more youth-appealing elements.
