I have a friend who needs some eye surgery done, and they refuse to operate on her till she is at least 3 months smoke free. Not cut back, or cut down, but smoke free.
My sister who is a hypochondriac runs from MD to MD looking for pills or surgery or whatever, and she too is recently finding many MDs wont touch her till she quits smoking. She needs her replacment hip to be repaired and they wont touch her till she has quit for six months. She has lied to several and told them she stopped, but they smell it on her, and told her when her blood test show clean, they can fix it.
Smoking is horrible for you.
