In brief: Smoking

Nicotine is a known vasoconstrictor. It is known to narrow vessels.
Compounds in cigarettes also damage the insides of vessels. Excessive smoking magnifies the problem. This puts patients at risk for losing limbs. Drinking does not have the vascular issues but there are many other issues associated with heavy drinking.
