Fans were shocked when talented 'Glee' star Cory Monteith passed away in the summer of 2013.  Cory's death was discovered when he failed to check out of his hotel room in Vancouver, Canada, and was ruled a result of "mixed drug toxicity" due to heroin and alcohol. The actor had struggled with substance abuse since the age of 12; and as recently as March 2013 he had checked into a rehab center for help with his addiction.

Lea Michele (Cory's girlfriend and 'Glee' co-star) spoke some words of comfort at the '2013 Teen Choice Awards':

"For all of you out there who loved and admired Cory as much as I did, I promise that with your love we’re gonna get through this together. He was very special to me and also to the world."

Unfortunately, Cory Monteith is not the only star who lost his life due to drugs. Read on to remember other celebrities whose lives were tragically cut short.
