Add one more to the list of celebrities speaking out from first-hand knowledge about the benefits of medical marijuana. Reality TV star, Diem Brown, tells People magazine that vaporizing the plant reduces her pain and is helping her gain weight before chemotherapy for colon cancer.

Brown joined MTV’s reality competition, The Challenge, in 2006. As a new member, or “fresh meat”, she competed against former cast members of the network’s Real World/Road Rules series. While some of her competitors had experience on reality TV, the 24-year-old knew the struggle of a far greater challenge fighting for her life. Brown revealed during her first challenge on the show in 2006 that she had just completed treatment for ovarian cancer.
