Corey Haim is not the first—or the last—former child star who became a drug addict. Some make a full recovery. Many, sadly, do not.

Whether it's the fame at a young age and an inability to cope when it goes away, or the idea that, thanks to their celebrity status, they can get away with anything, there are a million possible explanations why child stars end up turning to drugs and alcohol later in life. It's not a nice trend, but based on all this evidence, it's very real indeed.
