Prevalence, Trends, and Distribution of Nicotine and Marijuana use in E-cigarettes among US adults: The Behavioral Risk Factor Surveillance System 2016-2018.

Introduction:
This text is a summary of a scientific study examining the prevalence and trends of nicotine and marijuana use in e-cigarettes among US adults. The study uses data from the Behavioral Risk Factor Surveillance System from 2016-2018. The study aims to describe the emerging dual nicotine and marijuana vaping population and examine trends in marijuana use, including marijuana vaping.

Key Points:

* The study found that 7.1% of current e-cigarette users also vaped marijuana.
* Prevalence of nicotine-predominant, dual nicotine marijuana, and marijuana-predominant vaping was 3.36%, 0.38% and 1.09%, respectively.
* Compared to nicotine-predominant vapers, dual and marijuana-predominant vapers were older, had greater proportions of non-Whites, particularly hispanics, and less likely to be current smokers.
* The proportion of dual vapers among current e-cigarette users was 8.6%, 2.6% and 7.1% for 2016, 2017 and 2018, respectively.
* Prevalence of marijuana use increased from 8.97% (2016) to 13.1% (2018) while no clear trend was observed for marijuana vaping.
* Dual nicotine and marijuana vaping is prevalent in the US and represents a large and important emerging population that will require dedicated study of health effects and tailored regulatory strategies.

Main Message:
The study highlights the growing trend of dual nicotine and marijuana vaping among US adults and the need for regulatory strategies and health education to address this emerging population. The study's findings can inform policy decisions regarding e-cigarette regulations and public health initiatives. It is crucial to monitor and regulate e-cigarette use, especially in light of the potential dangers associated with marijuana vaping, as seen in the 2019 EV aLI outbreak.
