vaping

can someone explain to me what it actually is?

i've heard it in a lot of places (including this site)

I get the feeling it's something related to smoking, but correct me if i'm wrong

It's using an e-cigarette to smoke. You inhale diluted nicotine vapour, hence the name.

Its inhaling and exhaling the vapor produced by an electronic cigarette. It is an alternative to smoking. E-cigarettes are battery-powered devices that heat a liquid — usually containing nicotine mixed with the chemicals propylene glycol and glycerin, and often flavorings ranging from bubble gum to watermelon — into a vapor that users can inhale. They deliver nicotine to the body in various ranges.

You can also vape marijuana as an alternative to smoking. Same premise as the e-cigarettes described above.

thanks for the responses.

I guess I was pretty close when I said it was to do with smoking
