Trends in Use and Perceptions of Nicotine Vaping Among US Youth From 2017 to 2020
Published: 15/12/2020, JAMA Paediatrics
Conclusions and Relevance Increasing US adolescent nicotine vaping trends from 2017 to 2019 halted in 2020, including a decline in daily vaping. Decreases in perceived accessibility of some vaping products, as well as increases in perceived risk of nicotine vaping, occurred from 2019 to 2020. Yet, adolescent nicotine vaping remains highly prevalent, flavors remain highly accessible, and declines in JUUL use were countered by increased use of other brands.
Electronic cigarette use and risk of cigarette and smokeless tobacco initiation among adolescent boys: A propensity score matched analysis
Published: 16/12/2020, Addictive Behaviours
Results Compared to non-users, e-cigarette users were more than twice as likely to later initiate both cigarette smoking (RR = 2.71; 95% CI: 1.89, 3.87) and SLT (RR = 2.42; 95% CI: 1.73, 3.38). They were also more likely to become current (i.e., past 30-day) cigarette smokers (RR = 2.20; 95% CI: 1.33, 3.64) and SLT users (RR = 1.64; 95% CI: 1.01, 2.64).
Young adults’ vaping, readiness to quit, and recent quit attempts: The role of co-use with cigarettes and marijuana
Published: 17/12/2020, Nicotine and Tobacco Research
Implications: The vast majority of young adult e-cigarette users use other tobacco products and marijuana. Unfortunately, few reported readiness to quit or attempting quit. Moreover, certain subgroups (e.g., sexual/racial/ethnic minorities) are more likely to be ready or attempt to quit, but may not be successful. Vaping cessation interventions must attend to these nuances
Current Perspectives on Characteristics, Compositions, and Toxicological Effects of E-Cigarettes Containing Tobacco and Menthol/Mint Flavors
Published: 19/11/2020, Frontiers in Physiology
In this review, we evaluate the current toxicological data of e-cigarettes with regard to effects upon exposure in animal models and in vitro cell culture for menthol/mint flavorants. We have tabulated the current e-cigarette products containing these most common flavors (menthol, mint, and tobacco) in the market. We have also indicated the prevalence of tobacco and menthol-flavor use among e-cigarette users and highlighted the possible challenges and benefits that will result from new federal regulations.

Smoking cessation: strategies and effects in primary and secondary cardiovascular prevention
Published: 16/12/2020, Panminerva Medicine
In this article we review the results of several large systematic reviews and metaanalyses, which have shown that many cessation strategies are effective. We also offer practical tips on providing brief cessation advice and how pharmacotherapy can be prescribed and incorporated into clinical practice in both primary and secondary cardiovascular prevention.
Association Between Smoking and Premenstrual Syndrome: A Meta-Analysis
Published: 26/11/2020, Frontiers in Psychiatry
Result: Smoking was associated with an increased risk for PMS. Smoking may lead to worsening of PMS symptoms because nicotine has effects on neurocircuitry that increases susceptibility to environmental stressors. Indeed, prior evidence shows that the hypothalamic-pituitary-adrenal (HPA) axis is already sub-optimal in PMS, hence, smoking likely further deteriorates it. Combined, this complicates the clinical course for the treatment of both PMS and Tobacco Use Disorder in this population.
Pharmacogenetics factors influencing smoking cessation success; the importance of nicotine metabolism
Published: 16/12/2020, Expert Opinion in Drug Metabolism and Toxicology
Expert opinion: Evidence supports the use of tailored therapies to ensure that the most efficient treatments are utilized in an individual's smoking cessation efforts. An understanding of the genetic effects on the efficacy of individualized smoking cessation pharmacotherapies is key to smoking cessation, ideally utilizing a polygenetic risk score that considers all genetic variation.

Published: 15/12/2020, Nicotine and Tobacco Control
This Special Issue on respiratory disease associations with cigarettes and non-cigarette nicotine and tobacco use includes a collection of multidisciplinary studies that begin to examine the effect of tobacco and nicotine use from the cellular level to patterns of use and symptomology at the population level
Tobacco 21 adoption decreased sales of cigarette brands purchased by young people: a translation of population health survey data to gain insight into market data for policy analysis
Published: 03/12/2020, Tobacco Control
Introduction Policies raising the minimum age of sale of tobacco products to 21 (T21) proliferated at state and local levels across the USA before a federal policy was adopted. Evidence of the effectiveness of these policies is building and lags implementation. This study exploits demographic patterns of cigarette brand purchasing to evaluate the effectiveness of T21.
Is the tobacco ‘footfall’ argument justified for tobacco purchases in New Zealand convenience stores?
Conclusions Our results do not support claims that tobacco drives one-quarter of footfall into stores or that customers who purchase tobacco spend almost twice as much as non-tobacco customers. Combined purchases of tobacco and non-tobacco items constituted 5.5% of transactions; the impact on a store’s profitability of removing tobacco sales is unknown and could be the focus of future research. Conclusion This study adds compelling empirical evidence that T21 decreased purchases of the cigarette brands consumed disproportionately by young people, the policy’s target demographic
Tobacco withdrawal symptoms before and after nicotine deprivation in veteran smokers with posttraumatic stress disorder and with major depressive disorder
Published: 27/11/2020, Nicotine and Tobacco Control
Conclusions These findings suggest that chronically high levels of distress and craving, rather than acute increases in withdrawal symptoms due to nicotine deprivation, may account for the quitting difficulties of those with comorbid conditions such as PTSD and MDD.
Do Young Adults Attend to Health Warnings in the First IQOS Advertisement in the U.S.? An Eye-Tracking Approach
Published: 27/11/2020, Nicotine and Tobacco Control
Conclusions The results revealed the effects of IQOS promotional content overshadowed the two health warnings in influencing young people’s attitude and intention to use IQOS. Young adults who vaped were more vulnerable to HTP advertising with respect to future use and vaping may be a gateway to HTP use.
Behavioral Economic Demand for Alcohol and Cigarettes in Heavy Drinking Smokers: Evidence of Asymmetric Cross-commodity Reinforcing Value
Published: 28/11/2020, Nicotine and Tobacco Research
Conclusions These results advance our understanding of the overlap between cigarette and alcohol by demonstrating that involvement with one substance was associated with demand for the other substance. This asymmetric profile—from smoking to alcohol demand, but not vice versa—suggests that it is not simply tapping into a generally higher reward sensitivity and warrants further investigation.

Conclusions This study supports a very low nicotine cigarette (VLNC) standard in cigarettes.
The impact of including cessation resource information on health warnings on standardised tobacco packaging on awareness and use: A longitudinal online survey in the United Kingdom
Published: 30/11/2020, Nicotine and Tobacco Research
Results Among smokers recalling seeing information about a stop-smoking website, citing warnings as a source increased between waves (W1=14.0%, W2=24.2%, W3=25.1%) and was associated with having visited a stop-smoking website (OR=11.81, 95% CI 8.47-16.46). Citing warnings as a source of a stop-smoking website increased among exclusive RYO smokers at each wave (W1=15.5%, W2=26.3%, W3=32.1%), while for exclusive cigarette smokers it only increased at W2 (W1=10.5%, W2=22.4%, W3=19.9%).

Maternal Smoking in Pregnancy and Child's Hospital Use up to 5 Years of Age in a Data Linkage Birth Cohort
Published: 02/12/2020, Hospital Paediatrics
Results: Among 36 630 infants, 21% were exposed to maternal smoking during pregnancy. Exposed children had a 26% higher rate of presentation to the emergency department (IRRadjusted 1.26; 95% CI 1.23-1.29) and a 45% higher rate of admission (IRRadjusted 1.45; 95% CI 1.39-1.51) at up to 5 years of age. Compared with the negative control, higher presentation and admission rates were evident in respiratory; eyes, ears, nose, and throat; psychosocial; and infectious disease categories.
Depression, smoking, and lung cancer risk over 24 years among women
Published: 03/12/2020, Psychological Medicine
Results: We identified 1009 cases of lung cancer. Women with the highest v. lowest level of depressive symptoms had an increased lung cancer risk (HRsociodemographics-adjusted = 1.62, 95% CI 1.34-1.95; HRfully-adjusted = 1.25, 95% CI 1.04-1.51). In a test of mediation, lifetime pack-years of smoking accounted for 38% of the overall association between depressive symptoms and disease risk.
