Hypoxia-Ischemia (HI) is a combination of reduced blood flow which cannot support normal organ function combined with less than normal oxygen levels. If this occurs in the brain then long lasting tissue damage and functional impairment can occur. In this study, newborn rats were subjected to HI and one group was administered cannabidiol (CBD), a […]
Neurogenesis is the growth and development of nerve tissue and is influenced by external factors such as enriched environments. Some researchers postulate that such neurogenesis in the hippocampus region of the brain contributes to improved learning and memory. This study was designed to observe the effect of THC on neurogenesis and the associated cognitive performance […]
As part of the past propaganda surrounding cannabis (marijuana) it was suggested that consumption of this plant would change a persons brain structure, creating alterations that could be seen on it’s surface. In this study, a multi-site data set of 120 controls and 141 cannabis users were examined regarding differences in cortical (surface) structure of […]
614 Italian patients were evaluated in this study on cannabis (marijuana) for pain relief. Cannabis was added to the pain regimen of these mostly female individuals who averaged 61 years of age. At the initial follow up which averaged 98 days after adding cannabis to their treatment regimen, 76% of the patients were continuing marijuana […]
Inflammatory bowel diseases (IBD) include chronic diseases such as Crohn’s and ulcerative colitis, and are known to respond to cannabis (marijuana) preparations but there are hundreds of compounds in the plant. This study was designed to determine which component was most likely to represent the beneficial anti-inflammatory effect seen on bowel conditions. The authors determined […]
There has been much concern and debate regarding adolescent cannabis (marijuana) use and effects on cognitive behavior, including IQ (Intelligence quotient) and educational results. This study evaluated 2235 teenagers from the Avon Longitudinal Study of Parents and Children in order to assess any relationship between cumulative cannabis use and IQ at the age of 15, […]
Lack of oxygen to the brain is a common scenario in stroke, respiratory arrest and cardiac arrest. Even when blood flow is restored there is often additional damage as inflammation and oxidative stress set in which damages brain neurons. In this study on mouse brain cells, it was found that treating with CBD (a component […]
Life expectancy for pancreatic cancer really hasn’t changed in the last 40 years or so, and only about 5% survive 5 years. In this study of pancreatic ductal adenocarcinoma it was shown that adding CBD from cannabis (marijuana) to the treatment regimen in these mice nearly tripled the survival time. The authors recommend that clinical […]
It is quite natural to have concerns about inhaling smoke into ones lungs, especially when we consider the damaging effects of cigarette smoking. However, smoking cannabis (marijuana) has continued to demonstrate a lack of similar damage when studied. This study evaluated the oxidant material created by macrophages in the air sacs of the lungs, comparing […]
Research on the effects of smoking cannabis (marijuana) and any effects on the lungs continue to show that it does not have the detrimental effects so common from cigarette smoking. Chronic obstructive pulmonary disease is a severe health challenge, and can be evaluated by testing how hard a person can expel air from their lungs, […]
