What is wrong with Anthony Kiedis?

I watched Live Earth and the performance was sad, why's he sick?

I know he USED to be an addict? but he really did not seem his usual self, was looking forward to seeing the RHTCP's since I found out they were headlining!!! very dissapointing

I don't know, but SOMEthing is up. He used to be soooo fine to me! I used to have the biggest crush on him. Look at his teeth. Something is up. I think he must mess with some kind of drug...what else would mess his teeth up that fast? He keeps on, his voice is gonna be jacked up too, if it isn't already.
