Striking lung cancer response to self-administration of cannabidiol: A case report and literature review, Josep Sulé-Suso et al., 2019

Striking lung cancer response to self-administration of cannabidiol : A case report and literature review Josep Sulé-Suso, Nick A Watson, Daniel G van Pittius, Apurna Jegannathen SAGE Open Medical Case Reports, 2019, 7, 1-4.   Abstract : In spite of new drugs, lung cancer is associated with a very poor prognosis. While targeted therapies are improving outcomes, it is not uncommon for many patients to have only a partial response, and relapse during follow-up. Thus, new drugs or reevaluation of existing therapies used to treat other non-malignant diseases (drug repurposing) are still needed. While this research both in vitro and in vivo is being carried [...]

Cannabidiol in Anxiety and Sleep : A Large Case Series, S. Shannon et al. , 2019

Cannabidiol in Anxiety and Sleep : A Large Case Series SHANNON S., LEWIS N., LEE H., HUGHES S. The Permanente Journal, 2019, 23   Abstract CONTEXT: Cannabidiol (CBD) is one of many cannabinoid compounds found in cannabis. It does not appear to alter consciousness or trigger a "high." A recent surge in scientific publications has found preclinical and clinical evidence documenting value for CBD in some neuropsychiatric disorders, including epilepsy, anxiety, and schizophrenia. Evidence points toward a calming effect for CBD in the central nervous system. Interest in CBD as a treatment of a wide range of disorders has exploded, yet few clinical studies of [...]
