Trends in frequency of e-cigarette use among cancer patients and survivors in the United States, 2014-2018.

Introduction:
This text summarizes the findings of a study that analyzed data from the National Health Interview Survey from 2014 to 2018 to determine trends in the frequency of e-cigarette use among cancer patients and survivors in the United States. The study aimed to provide information on active usage and frequency of use among cancer survivors.

Key Points:

* The study found that the majority of cancer survivors who have ever used e-cigarettes do not appear to be actively using them.
* The reported increasing popularity of e-cigarettes may be driven by a growing absolute proportion of individuals trying e-cigarettes over time.
* Those who were current or former traditional cigarette smokers were more likely to actively use e-cigarettes.
* The study used data from the National Health Interview Survey from 2014 to 2018.
* The sample was limited to cancer patients and survivors who reported ever using e-cigarettes.
* The study defined active e-cigarette usage as using e-cigarettes every day or some days.
* The study controlled for sex, age, race, ethnicity, education, traditional cigarette smoking status, and year of the survey.
* The study found that later year of survey, black race, and age 45-54 were negatively associated with active e-cigarette usage.

Main Message:
The study provides important information on trends in e-cigarette usage among cancer patients and survivors. The findings suggest that the increasing popularity of e-cigarettes may be due to a growing number of individuals trying them, rather than an increase in active usage among cancer survivors. The study also highlights the importance of considering traditional cigarette smoking status when examining e-cigarette usage. The results can help inform current policies on e-cigarettes and contextualize studies on long-term effects of e-cigarettes among survivors of cancer.
