In brief: LowerPressure is Key

Veins have smooth muscle in their walls, but much less than arteries, operate at much lower pressures than arteries, typically <5 to >15 mmhg above atmospheric pressure, and there is no pulse with each heart beat.
However arteries typically operate at pressures >100 to >200 mmhg above atmospheric pressure and stretch with each heart beat. Veins develop atherosclerosis rapidly if used as an artery.

In brief: Atherosclerosis

Atherosclerosis develops in the portion of the artery wall that is muscular. There is no muscle in veins, so plaque does not develop in these types of vessels.
