Having throat/voice problems are not just caused by smoking, especially when they're singing on Broadway 8 times a week. Unless you personally are Carly or Raul's ear, nose, and throat specialist, you can't point to smoking as the cause.
I don't know why everyone is freaking out about actors they like smoking. It's their career that's in the toilet if they f*ck up their voices up too bad, so I doubt they'll let their habit get that out of hand, and they will still be able to perform years after you've moved on.
