Objective: The aim of this study is to examine the association between nicotine dependence and longitudinal exercise transitional shift patterns among young U.S. adult daily smokers.
Methods: Data from the 2003-2005 National Youth Smoking Cessation Survey was used, which is a longitudinal study over a two year period. Participants included 1168 US adult daily smokers (18-24years). Nicotine dependence was assessed using the modified Fagerstrom Test for Nicotine Dependence. Four transitional shift patterns were created based on meeting current exercise guidelines; stable inactive (inactive across time), activity relapsers (starts out active and then becomes inactive), activity adopters (inactive and then becomes active), and stable active (active across time).
Results: After adjustments, for every 1-unit increase in baseline nicotine dependence, participants had 16% (OR=1.16, p=0.01) greater odds of being in the stable inactive group compared to the stable active group.
Conclusions: Nicotine dependence appears to play an important role in shaping longitudinal exercise patterns among young U.S. adult smokers.

Current scientific evidence shows both the relationship between good physical condition and a lower incidence of certain chronic diseases (including smoking), as well as the efficacy of cytisinicline. The aim of this protocol is to evaluate the efficacy of the synergistic effect of the combination of targeted physical exercise, together with brief advice and taking the drug cytisinicline, to achieve smoking cessation. : We propose an experimental, multicentre, randomised, controlled study with two parallel arms to be carried out by a multidisciplinary team in the primary care setting of the Andalusian public health system (APHS) in Spain, with a follow-up of 12 months.

Background: The WHO has highlighted that: "promotion of e-cigarettes has led to marked increases in e-cigarette use by children and adolescents." The long-term neuropsychiatric and psychological consequences of substance abuse in adolescence is well recognised. Limited data exists on the adolescent burden of vaping-related nicotine addiction and behavioural and/or psychological dependence to guide pharmacological or behavioural interventions to stop electronic cigarette usage.

Though widely consumed, current research on the neural mechanisms of arecoline, caffeine, and nicotine remains limited, and the similarities and differences of these substances on the nervous system are still not clear. This study used RNA-seq to analyze the gene expression in the nucleus accumbens (NAc) of mice, and compared the behavioral changes through open field and conditioned place preference (CPP), exploring the effects of different psychoactive substances at transcriptional and behavioral levels. Gene Ontology enrichment analysis revealed that nicotine and caffeine significantly alter biological processes related to synaptic function, and KEGG pathway analysis showed that the differentially expressed genes in the nicotine-treated group were significantly more enriched in pathways related to substance dependence, with arecoline showing the least enrichment.

Aims: People often drink alcohol and use other substances concurrently, increasing the risk of adverse health outcomes. Our aims were to: (i) assess temporal trends in tobacco and/or cannabis use by varying alcohol consumption levels and (ii) identify associated factors of polysubstance use in high-risk alcohol users.
Methods: We conducted a repeated cross-sectional study combining 2010-19 U.

Objectives: In this study, we aimed to demonstrate the effect of motivational interviewing with a specific cohort of smokers on smoking cessation. Furthermore, we investigated the influence of medical conditions and individual traits on the efficacy of motivational interviewing for smoking cessation.
Methods: This prospective study was conducted with smokers who presented at the pulmonology and cardiology outpatient clinic.
