The re-emergence of the “choking game” on social media has sparked concerns amongst teachers at Kelvin Grove State College, who are urging parents to caution their children on participating in it.

In an email sent to parents, the school’s principal noted there are over 36 million YouTube results for how to play the self-asphyxiation game linked to the death of a Queensland teenager two years ago.

In a Queensland Health statement released yesterday, a spokesperson said there is no safe way to starve oneself of oxygen, and that comas and long-term brain damage are known risks associated with the practice.
