Teenagers risk kidney failure in drug craze

“Ketamine, a powerful tranquilliser used on horses, is being taken in growing number by young people in the UK, causing crippling health problems.

Some addicts have needed to have their bladders removed and must now wear catheters. Other users have suffered serious kidney problems, breathing difficulties, addiction, bouts of unconsciousness and trouble with urinating. The drug also involves a heightened risk of heart attack.”
