The majority of problems associated with smoking in the lower extremities are a direct result of impaired blood flow. Chronic tobacco use raises blood pressure and constricts blood vessels. The blood which flows through these narrowed vessels becomes turbulent and the walls of the vessels, especially the arteries, are damaged. The end result is the development of atherosclerosis. This condition results in the narrowing of the large and also small vessels in the human body. The effects are well known in the lower extremities with the greatest effect in the feet.
Diminished blood flow and eventually absent blood flow results in cell death and gangrene with the need for amputation.
