A 19-year-old British college student stabbed his mother before slicing off his own penis last month after taking a synthetic drug called mephedrone, better known as "Meow Meow."
According to the UK Mirror, police found the teenager dangling his severed penis out of a window, spraying blood on whoever was unfortunate enough to walk by.
London police rushed the boy and his 46-year-old mother to a nearby hospital, where they were both treated for life-threatening injuries.
A source close to the West Sussex family told the Mirror:
"He is normally a lovely lad and very bright. But unfortunately, he had started dabbling in drugs. He had come home from university for Christmas. It looks like he took mephedrone and completely flipped out attacking his mum and then himself. When the police arrived they found him hanging from a window and then discovered he had cut off his penis."
Both the boy and his mother were reported to be in stable condition, and surgeons were able to successfully reattach the penis.
Mephedrone is a popular illegal party drug in the UK that is also known by street names "drone," "meow meow" and "MCAT."
It apparently produces similar effects to cocaine, an energetic body high that could also turn into paranoia and anxiety if abused.
