Abstract
Background
There is a knowledge gap in the short- and long-term tobacco use patterns of adults who smoke cigarettes and initiate use of electronic cigarettes. This longitudinal study describes concurrent use transitions following e-cigarette initiation among adults who smoked cigarettes.
Methods
From December 2020-October 2021, US adults who smoked cigarettes and recently (re-)initiated e-cigarette use within the past month (N = 303) were recruited nationally for a one-year online study consisting of weekly surveys for three months followed by three quarterly surveys. At each survey, current e-cigarette use, smoking status, and frequency of use were assessed to define their concurrent use state: neither vaping nor smoking, vaping only, predominantly vaping, equal dual use, predominantly smoking, or only smoking.
Results
During the first 3 months, 74 % of participants shifted their usage states at least once, while 29 % shifted between 9 months and 12 months following e-cigarette initiation. Participants predominantly smoking initially tended to either continue predominantly smoking or returned to exclusively smoking. Those predominantly vaping tended to remain in this state or shift to only vaping. Individuals using both products split early between continued dual use, predominantly vaping, and predominantly smoking. Those only vaping tended to continue, although some reverted to smoking. Overall, initial concurrent use states appear somewhat predictive of trajectories and 12-month outcomes.
Conclusions
Additional research on predictors (e.g., demographics, product characteristics, use experiences, perceptions and affect, product availability) of these frequent shifts between concurrent use states on weekly, monthly, and quarterly basis and 12-month outcomes is needed.
期刊介绍:
Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings.
Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
