You should not smoke after finger amputation surgery, especially within two weeks after the surgery, because within two weeks the local blood circulation is not yet stable. It is widely recognized that smoking is not good for human health, so both healthy people and patients with diseases should not smoke. Smoking is even more harmful to patients with broken fingers, because there is a local blood circulation disorder and there is a recovery process after the surgery, usually within two weeks, and smoking within two weeks often leads to finger necrosis, after two weeks it is relatively safe. However, for the sake of health, especially patients with broken fingers should refrain from smoking for the sake of health and better finger recovery.
