ENDS DEVICE TYPES AND SUBSEQUENT USE OF COMBUSTIBLE TOBACCO PRODUCTS AMONG TEXAS YOUTH

The aims of the study were to determine whether ENDS device types (i.e., disposable devices, replaceable cartridges, and refillables) at initial, or first ENDS use is longitudinally associated with subsequent initiation of combustible tobacco products (cigarettes, hookah, cigars) and continued, past 30-day use of combustible and ENDS products. This study is a secondary analysis of data from the Texas Adolescent Tobacco and Marketing Surveillance system (TATAMS) study, a longitudinal cohort study of students who were in the 6th, 8th, and 10th grades (n = 3907) during the 2014-2015 academic year. Data were collected every 6 months, from 2014-2018. Using data from all 8 waves of the study, descriptive statistics were computed for initial ENDS device type (disposables, cartridges, and refillables), initial and past 30-day use of combustible tobacco products (subsequent to ENDS use), and past 30-day ENDS use (among ever ENDS users). Unadjusted and adjusted logistic regression models were computed to assess the likelihood of (a) initiation of combustible tobacco products in subsequent waves, (b) continued use of combustible tobacco products (past 30-day use) and (c) continued use of ENDS products (past 30-day use) in the same or subsequent waves, by initial ENDS device type. After adjusting for the sociodemographic variables, compared to participants initiating with Refillables, participants initiating ENDS use with Cartridges and Disposables were 58% (AOR = 0.42; 95% CI = 0.18 – 0.98; p = 0.05) and 53% (AOR = 0.47; 95% CI = 0.21-1.07; p = 0.07) less likely to initiate combustible tobacco use in a subsequent wave. Compared to participants initiating with Disposables, participants initiating ENDS use with Cartridges were 12% (AOR = 0.89; 95% CI = 0.32 – 2.50; p = 0.89) less likely to initiate combustible tobacco use in a subsequent wave. Compared to participants initiating with Disposables, participants initiating ENDS use with Cartridges were 12% (AOR = 0.88; 95% CI = 0.21 – 3.68; p = 0.86) less likely to have reported combustible tobacco use in the past 30-days. Compared to participants initiating with Disposables, participants initiating ENDS use with Cartridges were 62% (AOR = 0.38; 95% CI = 0.16 – 0.92; p = 0.03) less likely to have reported ENDS use in the past 30-days. The study provides an insight into the impact device types can have on future smoking behavior and the implication it can have on policy and regulation

Symptoms of Depression and Anxiety and Subsequent Use of Nicotine and THC in Electronic Cigarettes

Background: This study examines whether symptoms of depression, anxiety, or comorbid depression and anxiety are associated with future use of nicotine or THC in e-cigarettes. Methods: Data were from an online survey of youth and young adults in urban areas of Texas with complete data (n = 2,307) in spring 2019 (baseline) and spring 2020 (12-month follow-up). Multivariable logistic regression models examined associations between self-reported symptoms of depression, anxiety, or comorbid depression and anxiety at baseline and past 30-day e-cigarette use with nicotine or THC at 12-month follow-up. Analyses adjusted for baseline demographics and baseline past 30-day e-cigarette, combustible tobacco, marijuana, and alcohol use and stratified by race/ethnicity, gender, grade level, and SES. Results: Participants were 16-23 years old, 58.1% female and 37.9% Hispanic. At baseline, 14.7% reported symptoms of comorbid depression and anxiety, 7.9% depression, and 4.7% anxiety. Prevalence of past 30-day e-cigarette use at 12-month follow-up was 10.4% with nicotine and 10.3% with THC. Symptoms of depression and comorbid depression and anxiety at baseline were significantly associated with both nicotine and THC use in e-cigarettes 12 months later. Symptoms of anxiety were associated with nicotine use in e-cigarettes 12 months later. Conclusions: Symptoms of anxiety and depression may be important indicators of future nicotine and THC vaping among young people. Clinicians should be aware of groups most at risk who may benefit from substance use counseling and intervention

Cannabis vaping among youth and young adults: a scoping review.

Purpose of review: The purpose of this review was to describe the state-of-the-literature on research specific to cannabis vaping among youth and young adults. Recent Findings: Out of 1801 records identified, a total of 202 articles met eligibility criteria for inclusion in this review. Most of this literature (46.0% of studies) was specific to the health effects of cannabis vaping, particularly EVALI (e-cigarette and vaping associated lung injury). Other research areas identified in the review included the etiology (24.3%) and epidemiology (24.8%) of cannabis vaping, in addition to articles on regulation (8.4%) and marketing (5.5%) of the same. Summary: Cannabis vaping is increasingly common among youth and young adults and more prevalent is settings where recreational use for adults has been legalized. The literature documents a number of negative health effects of cannabis vaping for young people, along with risk factors and reasons for the same
