Theodorou was a proud medical cannabis activist and received a therapeutic use exemption (TUE) from the British Columbia Athletic Commission in January 2020, making him the first professional athlete in North America to be sanctioned to utilize cannabis in-sport. In May 2021 he received a second such exemption from the Colorado Combative Sports Commission, making him the first professional athlete to receive a TUE in the United States. Theodorou used cannabis to treat the pain and discomfort from bilateral neuropathy, a nerve condition resulting from an accident that broke his hand in two places and fractured it in four.
