So I am scheduled to have my 4th and 5th knee surgery. It will be a 2 part, first clean and inspect and second surgery to replace and fix. My thing is the doctor told me I HAD to quit smoking or he would not do the surgery. Now I'm curious can he do that? He is actually having me do a nicotine test when I go back next week. I'm a Marlboro Red pack a day smoker. I have been able to cut back to maybe 1-2 cigarettes a day, but it is tough. I just didn't think a doctor, at least a military doctor could tell you you had to quit smoking.
