A new study from Augusta University, focused on glioblastoma, one of the deadliest and fastest growing forms of brain tumors, reveals that cannabidiol (CBD) is a beneficial form of treatment. The prognosis for glioblastoma is a 15 month survival rate following diagnosis, based on data from the Glioblastoma Foundation. Despite new research on the cancer over the last 15 years, survival has only increased by 2 months, explains Dr. Martin Rutkowski, a Medical College of Georgia at AU neurosurgeon, and one of the study’s researchers.
