A number of German teenagers have been inserting tampons soaked in vodka to get drunk quickly and hide the smell.
I believe this is very dangerous. For us this is a new thing.
Police in the Baden-WÃÂ¼rttemburg city of Tuttlingen have warned girls the new form of alcohol abuse could be damaging to their vaginal walls, while boys have reportedly been inserting the feminine care products anally.
A head of a children's clinic in Singen told southern German paper SÃÂ¼dkurier: "I believe this is very dangerous. For us this is a new thing."
The trend is known as "slimming" in the US and there are groups on social networking site Facebook dedicated to exchanging tips on the subject.
