Self-reported Marijuana Use in Electronic Cigarettes Among US Youth, 2017 to 2018.

Introduction:
This text summarizes a research study on the self-reported use of marijuana in electronic cigarettes among US youth in 2017 and 2018. The study used data from the National Youth Tobacco Survey to examine the prevalence and correlates of marijuana use in e-cigarettes. The key points and main message of the study are outlined below.

Key Points:

* The study found that the prevalence of self-reported marijuana use in e-cigarettes among US youth increased from 11.1% in 2017 to 14.7% in 2018.
* The increase in marijuana use in e-cigarettes was observed across various demographic groups, including male and female students, adolescents aged 13 to 17 years, high school students, and non-Hispanic white and Hispanic students.
* The largest increases in marijuana use in e-cigarettes were observed among current users of one tobacco product (33.2% to 40.6%) and those who lived with a household member using e-cigarettes (22.7% to 29.5%).
* In 2018, 42.7% of ever e-cigarette users, 53.5% of current e-cigarette users, and 71.6% of polytobacco users reported ever using marijuana in e-cigarettes.
* The study controlled for various factors, including demographics, tobacco use by a household member, ever and current e-cigarette use, frequency of current e-cigarette use, current cigarette smoking, current other tobacco use, and the number of tobacco products currently used by students.
* The study used a nationally representative sample of US youth and employed complex survey design methods to estimate the prevalence and correlates of marijuana use in e-cigarettes.
* The study's findings suggest that marijuana use in e-cigarettes is a growing public health concern that requires further research and surveillance.

Main Message:
The study highlights the increasing trend of marijuana use in e-cigarettes among US youth, which is associated with various demographic and tobacco use factors. The findings suggest that marijuana use in e-cigarettes is a significant public health issue that requires regulatory attention and further research. The study's results can inform policymakers, healthcare providers, and researchers about the need to address the rising use of marijuana in e-cigarettes among US youth.
