Is any celebrity death a real tradgedy?

In the past year a lot of famous people have passed on. At first the entire country seemed to be in shock. for example when Heath Ledger died. However later on i stopped feeling bad for them because every single death seems to be drug related somehow. The newest celebrity death was that of Brittany Murphy at just 32 years old! It is very unfortunate but now there are drug questions involved. The true reason for death will not be found for weeks. The autopsy still has to be performed. It is said she collapsed in the shower and had a heart attack. This case will be on the news for weeks. the most major recent celebrity death was that of michael jackson. He was a great entertainer and many people were very downtrodden. I felt sorry for him too until they started to bring up drug issues. i just dont get it. These people have everything they want and they waste their lives on drugs. I think they are just a bunch of idiot!
