They used data from the Health and Retirement Study and […]
The authors of this study did a secondary analysis of data from the Coronary Artery Risk Development in Young Adults (CARDIA) Study. They were investigating any relationship between cumulative lifetime and current marijuana (cannabis) use with abdominal fat, subcutaneous fat, intramuscular fat and any decreased function of the liver at midlife. 2902 participants who were […]
These authors state that metastasis is the main cause of death in patients with melanoma, and acknowledge that cannabis (marijuana) based drugs are effective adjunctive drugs in cancer patients. In this study, researchers evaluated the effectiveness of Cannabis sativa extract on cell migration and gene expression in the melanoma cell line. In the treatment group, […]
