Social media and E-cigarette use among US youth: Longitudinal evidence on the role of online advertisement exposure and risk perception.
Previous studies revealed a link between social media use and e-cigarette use among U.S. youth, but less is known about the mechanisms through which they interconnect. This study examined how social media and e-cigarette use are connected through online advertisement exposure and risk perception of e-cigarettes among U.S. youth. ⋯ The results indicate that social media use is associated with increased e-cigarette use through online e-cigarette advertisement exposure and subsequently decreased e-cigarette risk perception among U.S. youth. Our findings underscore the importance of regulating online e-cigarette advertisement, with the emphasis of avoiding information that could twist youth's risk perception of e-cigarettes, which may in turn curtail youth e-cigarette use.

Randomized Controlled TrialChanges in puffing topography and subjective effects over a 2-week period in e-cigarette naïve smokers: Effects of device type and nicotine concentrations.
This study aimed to document changes in puffing topography and, the effects of device type and nicotine concentration on puffing topography, subjective effects and smoking behaviour over two weeks of e-cigarette (EC) use. ⋯ Cigalikes and tanks were both effective for reducing craving, withdrawal symptoms and CPD although for the former, this may only be achieved through more frequent puffing. That the Tank18 yielded greater satisfaction suggests tank devices and higher nicotine concentrations may be more suitable in the early stage of a smoking cessation attempt.

Tobacco use severity in relation to opioid misuse and dependence among adult tobacco users with chronic pain: The moderating role of pain-related anxiety.
The opioid epidemic is a significant public health crisis that is often linked to chronic pain management. One ensuing consequence of long-term opioid use for chronic pain is a high potential for opioid misuse and dependence. Although tobacco is commonly used among individuals with chronic pain, it is associated with an increased risk for opioid-related problems. ⋯ Two hierarchical linear regression analyses were conducted to test main and interactive effects of tobacco use severity and pain-related anxiety for current opioid misuse and severity of opioid dependence. Results indicated a significant moderation effect, such that the relationship between tobacco use severity and opioid misuse and dependence was stronger among individuals with higher (but not lower) pain-related anxiety. These findings build upon the extant literature by demonstrating an interactive effect of tobacco use severity and pain-related anxiety in terms of opioid-related outcomes and suggest that current tobacco users with elevated levels of pain-related anxiety may be at increased risk for opioid misuse and dependence.

Multi-directional pathways of tobacco and marijuana use, including comorbid use, among a population-based cohort of adolescents in Texas: A six-wave cross-lagged model.
Past 30-day tobacco and marijuana use commonly occur among adolescents. It is unclear whether use of one product precedes the other, especially given the new climate surrounding marijuana legalization and the increasing popularity of e-cigarettes. ⋯ This is the first study to longitudinally situate comorbid, past 30-day use of tobacco and marijuana and simultaneously examine bi-directional past 30-day use of these products for adolescents. Marijuana use more often and more strongly predicted subsequent tobacco use than the reverse, especially during middle adolescence (13-15 years old). Marijuana use should be considered when creating interventions that address adolescent e-cigarette use in the U.S.

Preliminary impact of the COVID-19 pandemic on smoking and vaping in college students.
We examined tobacco use changes in young adult college students in the context of the COVID-19 pandemic, focusing on smoking and vaping. First, we evaluated changes in tobacco use from pre to post campus closure focusing on smoking and electronic nicotine vaping frequency (days) and quantity (cigarettes/cartridges per day). Also, given the potential protective effects of pausing (temporarily or permanently discontinuing) smoking or vaping, we evaluated its predictors. ⋯ Twenty-four participants (28.9%) paused past-week use SC. Higher anxiety and moving home (versus living independently) were related to increased odds of pausing, whereas COVID-19 related news exposure and seeking were related to decreased odds of pausing. Characterizing COVID-19 related tobacco use change provides insights into how college students respond to novel health threats and informs potential interventions.
