The CDC and the US Food and Drug Administration (USFDA) discovered this new trend from surveys filled out by 17,000 high school students across America in 2015.

About 38% of high school students who took the survey revealed they have tried e-cigarettes before.

An e-cigarette is the most popular type of vaporiser but there are others such as box mod, oil vaporiser, wax vaporiser, and dry herb vaporiser. When you see people puffing out large clouds of vapour on YouTube they are mostly using these vaporisers.

At the 2016 SAG Awards, Hollywood actor Leonardo Di Caprio was seen puffing on a strange object. The environmental friendly movie star was vaping and this was probably the first mainstream shot of the alternative sub-culture.
