An apprentice plumber fell into a canal and drowned after playing a game of chemical Russian Roulette by mixing ketamine with alcohol, an inquest heard.
Matthew Dutton, 22, was left struggling to walk and acting like a robot after he mixed the party drug with alcohol during a night out in Wigan, Greater Manchester last August.
The man, who had been watching the Champions League final, was walking home alone later in the night when he slipped and fell into a stretch of the Leeds and Liverpool canal, the hearing in Bolton was told.
His body was found three days later by a police underwater search team, with tests showing he had significant levels of ketamine in his system on the night he died.
