Significance: Cannabis use is increasing among cigarette smokers. If cannabis use is associated with cigarette dependence, a barrier to smoking cessation, this could have public health implications for tobacco control. The current study estimated the prevalence of cigarette dependence among US individuals who smoke cigarettes by cannabis use status, and investigated trends in cigarette dependence from 2002 to 2019 among cigarette smokers by cannabis use status and cigarette consumption (ie, cigarettes per day, CPD).
Methods: Data were drawn from the 2002-2019 annual National Survey on Drug Use and Health and included US individuals aged 12+ years who used cigarettes at least once in the past month (n=231 572). Logistic regression was used to estimate the prevalence of cigarette dependence, measured as time to first cigarette <30 min, by past-month cannabis use (no use, non-daily use, daily use), and to estimate trends in cigarette dependence from 2002 to 2019 overall and stratified by cannabis use and smoking level (light, 1-5 CPD; moderate, 6-15 CPD; heavy, 16+ CPD).
Results: Across all levels of cigarette use, cigarette dependence was significantly more common among individuals with daily cannabis use compared with those with non-daily or no cannabis use. From 2002 to 2019, cigarette dependence increased among cigarette smokers with non-daily cannabis use, and among light and moderate cigarette smokers with no cannabis use.
Conclusions: US individuals who use both cigarettes and cannabis report a higher prevalence of cigarette dependence relative to individuals who use cigarettes and do not use cannabis at virtually all levels of cigarette consumption. Further, cigarette dependence is increasing in the USA both among those who use and do not use cannabis. Given the increase in cannabis use among those using cigarettes, efforts to elucidate the nature of the association between cannabis and cigarette dependence are needed.

This article serves as a guide to the Tobacco-Free Generation policy (TFG) for policy-makers, drawing on experiences of negotiations regarding TFG in a wide number of jurisdictions. It explains the underlying concept: the highly addictive nature of nicotine prompts policy focus on preventing initial use by forbidding sales to those born after a prescribed cut-off birthdate, while resisting prohibition for those in older cohorts who may already be nicotine-dependent. The policy signals that there is no safe age for tobacco products.

Importance: 2021 Advance child tax credit (ACTC) monthly payments were associated with reduced US child poverty rates; however, policymakers have expressed concerns that permanent adoption would increase parental substance use.
Objective: To assess whether 2021 ACTC monthly payments were temporally associated with changes in substance use among parents compared with adults without children.
Design, Setting, And Participants: The primary sample included adults aged 18 to 64 years who responded to the National Survey on Drug Use and Health in 2021.

Background: Alzheimer's disease (AD) has both genetic and environmental risk factors. Gene-environment interaction may help explain some missing heritability. There is strong evidence for cigarette smoking as a risk factor for AD.

Background: A Delphi study was conducted to reach a consensus among international clinical and health care experts on the most important health and functioning self-reported concepts when evaluating a switch from smoking cigarettes to using smoke-free tobacco and/or nicotine products (sf-TNPs).
Objective: The aim of this research was to identify concepts considered important to measure when assessing the health and functioning status of users of tobacco and/or nicotine products.
Methods: Experts (n=105), including health care professionals, researchers, and policy makers, from 26 countries with professional experience and knowledge of sf-TNPs completed a 3-round, adapted Delphi panel.

Cytoglobin (Cygb) regulates vascular tone by modulating nitric oxide (NO) metabolism in vascular smooth muscle cells (VSMCs). In the presence of its cytochrome B5a (B5)/B5 reductase-isoform-3 (B5R) reducing system, Cygb controls NO metabolism via oxygen-dependent NO dioxygenation. Electronic cigarette (EC) use has been shown to induce vascular dysfunction and decrease NO bioavailability; however, the role of Cygb-mediated NO metabolism in the pathophysiology of this process has not been previously investigated.
