Police say a teen high on a party drug commonly known as "meow meow" attacked his mother and then turned the knife to his groin, chopping off his own penis, the Daily Mail reports.
The 19-year-old UK college student was visiting his mother in England on Dec. 29 when he attacked the 46-year-old woman. When police arrived, the unnamed teen was hanging from a window at the home with a bloody groin.
A family friend told the Mirror that the man is a "lovely lad" who had started using drugs while in college. The drug use is believed to have prompted the attack.
Both mother and son are in the hospital, and reports suggest that the teen's penis has been re-attached.
Mephedrone -- also known as meow meow, drone and MCAT -- is a synthetic stimulant with effects similiar to cocaine or ecstacy, according to Drugscope.org.UK. A fairly new drug, meow meow was legal up until 2010.
