That's what Rick Simpson encountered in Canada
when he showed up at the Canadian Cancer Society with a cancer cure, his data, and a number of his former patients (cured or in remission). He demonstrated the efficacy of concentrated hemp oil (uh-oh!) on various tumors. Unable to refute his research (or the human success-stories who came with him), they saw their industry--including their own positions--threatened(!), and threw him out of their office.
