Vaping is becoming increasingly popular, but while the FDA in America has given it the seal of approval, do we know all there is to know about its effects yet? 

This short video from AsapScience takes a look at the differences between smoking tobacco or marijuana and using e-cigarettes or vapourisers with them instead. 

They explain the health risks associated with both, and the fact that there is not a lot of regulation regarding the use of e-cigarettes just yet, so there's still a lot to learn about how the body reacts to those substances.
