Scott's probably been puffing away on cigarettes since probably his teenage years I guess? So that makes his habit a little over 20 years. When you've been smoking for that long, it definitely begins to deteriorate your vocal chords and breathing ability. This is why he doesn't sound as good as he did even back during the last tour in 2001/2002. It's made him age a lot quicker as well.
It happens to many singers. Frank Sinatra began to lose his steam a tad in the 1970s because of what?...smoking. It's the dumbest thing a vocalist should ever do.
I hope Scott is at least down to smoking lights or something.
