Surgeon Dr David Soon said the man's daily habit caused a build-up of plaque around an artery in his big toe.
"Cannabis usage can cause the periphery blood vessel to tighten up and therefore increasing the resistance, and therefore increasing the amount of plaque depositing around the arteries, and therefore eventually narrowing the artery," Dr Soon told 3AW.
