Medical Oncologists’ Beliefs, Practices, and Knowledge Regarding Marijuana Used Therapeutically: A Nationally Representative Survey Study

Background Although almost every state medical marijuana (MM) law identifies cancer as a qualifying condition, little research supports MM’s use in oncology. Oncologists’ beliefs, knowledge, and practices regarding MM were examined in this study. Although 70% of oncologists do not feel equipped to make clinical recommendations regarding MM, the vast majority conduct discussions with patients about MM and nearly one-half do, in fact, recommend it clinically. A majority believes MM is useful for certain indications.
