^^Although Sambora is an integral part of Bon Jovi, it would be far easier to replace him in the middle of a world tour than Jon Bon Jovi himself, I have always maintained for better or worse in the majority of bands it's the lead singer that provides the signature sound.
Also this is not like cancer or a serious medical illness, this is about lack of self control and addiction and a relapse. While I agree with Groovy about him being in a bad way and needing to take care of his demons, when you are part of a band they have an even bigger responsibility to keep touring for their fans.
I am sure that a replacement guitarist can be found to fill in for now, finish the tour and that would be far better for everyone than canceling the rest of the concerts.
Bob, if I were you I would still go, they might never be back your way again so take this opportunity to see them live.
