Adolescent use of electronic vapor products (EVP) is increasing; however, changes in EVP use in the context of cigarette smoking is less certain. We analyzed trends in EVP and cigarette use among high school students in the state of Georgia. We used self-reported EVP and cigarette use from the annual for 2015 to 2018 (N = 1,405,108). Users were categorized as exclusive EVP users, exclusive cigarette users, or dual users. We assessed current (≥1 day in past 30 days) use of EVPs, cigarettes, and dual users of both products, as well as number of days the products were used among current users. We compared current users, as well as number of days used, across adjacent years using tests for proportion and Wilcoxon t-tests, respectively. The proportion of current exclusive EVP users and dual users increased during 2017-2018 (4.2% to 6.9% and 1.6% to 3.7%, < 0.001, respectively) after declining during 2015-2017, while the proportion of exclusive cigarette users declined during 2015-2018 (2.0% to 1.0%, < 0.001). Similarly, the mean number of days of EVP use increased among exclusive EVP and dual users, and mean number of days of cigarette use increased among dual users during 2017-2018 ( < 0.001). These findings reinforce the importance of continued efforts to reduce all forms of tobacco products use among Georgia high school students.

Introduction: Relative or absolute safety of heated tobacco products (HTP) remains unknown, while independent literature suggests that these products do not favour tobacco control. We conducted a comprehensive systematic review and meta-analysis to evaluate HTP usage patterns and the effect of HTP use on conventional tobacco smoking (use transitions).
Methods: We used Pubmed/MEDLINE, Embase and the Cochrane Library to identify all articles published up to February 2022 on HTP use.

Introduction Despite limited knowledge of its potential health effects, electronic cigarette (e-cigarette) use has become increasingly popular in the United States (US). Cigarette smoking is linked to a higher risk of asthma, and e-cigarettes may have similar effects. This study's aim was to examine the association between e-cigarette use and asthma exacerbations in US adults with known asthma.

The landscape of nicotine use in the United States (US) has continued to evolve, with electronic cigarette use (hereafter e-cigarette) becoming more evident in recent years. Patterns of dual nicotine use, or using combustible nicotine in conjunction with e-cigarettes, may increase dependence on nicotine, continued exposure to toxins, and corresponding health risks. One of the most prevalent health problems related to nicotine use is the experience of chronic pain.

Exosomes, crucial for intercellular communication, hold potential as noninvasive liquid biopsy biomarkers especially in early breast cancer detection benefitted from the distinctive "cancer signature" on their membrane surface. Yet, the present methodologies of exosomes for breast cancer detection have involved the implementation of only a single member from the tetraspanin protein group as a biomarker. Moreso, due to the high concentration of exosomes in complex body fluids, there is a compelling need to measure a small concentration of cancer-derived exosomes with a low background noise signal.

Objective: The potential impact of cigarette and cannabis smoking on COVID-19 infection outcomes is not well understood. We investigated the association between combustible tobacco use and dried cannabis use with COVID-19 infection in a longitudinal cohort of community adults.
Method: The sample comprised 1,343 participants, originally enrolled in 2018, who reported their cigarette and cannabis use in 11 assessments over 44 months, until 2022.
