GP highlights the dangers of ‘pass-out game’ among teens

A doctor has warned of the dangers of the "pass-out challenge" — a fad which is gaining popularity among teens on social media sites.

The challenge, also known as the ‘pass-out game’ or the ‘choking game’, involves teenagers depriving themselves of oxygen to achieve a high, which causes them to lose consciousness and faint.

The recorded footage is then uploaded on social media sites such as Snapchat and Instagram.
