Cory had been in Vancouver where he was visiting his mother. In April he had checked into rehab to treat an addiction to prescription pills and previously admitted to struggling with addiction since he was a teenager.
Speaking about his problems as a youth, Cory said he was lucky his addiction hadn’t killed him.
He explained: “I did anything and everything – as much as possible. I had a serious problem. I was out of control. I am lucky to be alive.”
'Glee' bosses have described Corey as “an exceptional talent and an even more exceptional person” following his death.
