Actor Matthew Perry’s death was an accident caused by the "acute effects of ketamine", medical officials in Los Angeles have confirmed.
The star was found unresponsive in the pool of his LA home in October, but a post-mortem examination was inconclusive at the time.
Drowning was listed as a contributing factor in his death.
He was best known for playing the wise-cracking Chandler Bing in the sitcom Friends.
At the height of his fame, Perry was battling with addiction to painkillers and alcohol, and attended rehabilitation clinics on multiple occasions.
