Pete Pearson, 74, is not ready to die. He was diagnosed six years ago with idiopathic pulmonary fibrosis, which has an average survival rate of 2-3 years after diagnosis. He knows he's on borrowed time, and has been dealing with anxiety and depression. That’s why he's seeking approval from Health Canada to use psilocybin as part of a treatment called psychedelic-assisted psychotherapy. His son Blake, who is also a family doctor, believes it can help his dad live the rest of his life to the fullest.
