* The lifetime prevalence of e-cigarettes vaping in the continents of america, Europe, asia, and Oceania were 24% (95% CI: 21--27%), 26% (95% CI: 21--31%), 16% (95% CI: 11--20%), and 25% (95% CI: 18--33%), respectively. The current prevalence of e-cigarettes vaping in the continents of america, Europe, asia, and Oceania were 10% (95% CI: 9--10%), 14% (95% CI: 10--17%), 11% (95% CI: 10--11%), and 6% (95% CI: 4--8%), respectively.
* The study found that the overall trend of e-cigarettes vaping from 2011 to 2019 showed an upward trend, with the current e-cigarettes vaping trend increasing from 2011 to 2014 and then showing an almost constant trend from 2014 to 2019.

Main Message:
The study suggests that the popularity of e-cigarettes is increasing globally, with a high prevalence rate in different populations, including adolescents and school students, adults, college students, and patients. The study emphasizes the need for countries to have more control over the consumption and distribution of e-cigarettes, as well as to formulate laws prohibiting e-cigarettes vaping in public places. The study also highlights the need for information campaigns to increase community awareness about e-cigarettes vaping.
