The youngster, identified as Shannon, describes her bizarre compulsion in a new documentary.
In it, it's said she necks up to 12 teaspoons of the fuel every day.
She claims: "It tingles at first and then it burns the back of my throat."
And she insists despite the pain involved in forcing down the harmful substance she cannot resist it, saying: "Even though it hurts me, it makes me feel good."
Caertainly not the cheapest of addictions ... :yuck:
