A concerning video showing a young Scottish guy downing TWO bottles of Buckfast tonic wine in 22 seconds is continuing to be widely-shared online.

Posted by user @AidanKennedy8, it shows a group of lads on their hotel balcony while on holiday in Magaluf.

After a short countdown from his pals in what looks to be a dare, the lad completely finished one bottle before moving onto the second after which his mates start to yell with excitement at the end.

Unsurprisingly, the guy doesn’t look like he’s up for celebrating much as he gestures to his pals to stop and back away.

The video has been widely-viewed having been posted onto Twitter just four days ago.

Some people have been quick to note the amount of booze units he consumes in such a short time - something which can be fatal.

With one bottle of the drink containing 11.25 units of alcohol, the man essentially drinks 23 units, just five short of the official recommended fortnightly maximum for a male.

In the past, the consumption of Buckfast has been strongly-condemned by alcohol charities, GPs - with even the makers of the drink cautioning that it should be consumed carefully.

Speaking with the Evening Times just last May, Dr Richard Simpson - a former GP and psychiatrist who stood down as Labour MSP for Mid-Scotland and Fife - blasted the annual World Buckfast Day which aims to celebrate the drink.

He referred to the day as "bizarre," adding: "It is irresponsible and there is no reason to do it.

"It is a drink primarily used by young men who want to get completely out of their minds drunk. But they become wide awake drunks and that can lead to problems.

"Research in US colleges on similar drinks found people were more likely to drive when drunk and young women more likely to get involved in sexual activity which they later regretted. Men were likely to be more aggressive.

"Buckfast is very much a West of Scotland problem, of course. In the East and North East, people don’t consume it in the way they do in the west, so it is basically a social thing."

Note: please don’t try this at home, folks.
