Mr. clark besson is undergoing extensive chemotherapy treatment for cancer. his oncologist recommended that he ingest marijuana to relieve the painful side effects. however, possession or use of marijuana is illegal in mr. besson’s state of residence. therefore, he makes a weekly trip to a neighboring state in which the medically pre- scribed use of marijuana is legal. since beginning his treatment, he has spent $2,730 to buy marijuana. is this a deductible medical expense?
