Are smokers or obese people not eligible for coronary artery bypass surgery?

No. They are higher risk but smoking or obesity is not contraindication for coronary artery bypass surgery.
CABG. No, they are still eligible, but their risks of surgery are much higher. Obesity and smoking would exclude one from getting a heart transplant though. Also, smoking would (at least in my practice) exclude you from having weight loss surgery.
Per se, no one is. Excluded. Risk analysis is done for everyone who needs cabg. Risks will always be a reality. But managing risks is the challenge to the "heart team", that includes the patient.
