Condom Snorting: Vile Teen Craze That Could Also Be Deadly

Now we all know that part of being a teenager is doing daft things. Been there, seen it, got the 'I'm an idiot' T-shirt.

But this latest craze surely takes the Hobnob. It's called Condom Snorting. And as dozens of teens demonstrate on YouTube, it involves snorting a condom (unused, thankfully) up one nostril, then hawking it up and pulling it out of their mouths.

It gives a whole new meaning to the word 'Gross'.

But for all its vileness, The Condom Challenge could also be a killer.

Dr Carol Cooper wrote in The Sun that teens taking part were risking their lives.

"It's shocking and incredibly stupid," she said. "The nose is connected to the back of the mouth - it's also connected to the airways.

"There's every possibility something you push up your nose will end up in your windpipe, or in your lungs. With potentially fatal results."
