The advocates of marijuana legalization are still motivated. However, a study has just shown the harmful effects of its consumption on the brain.
Marijuana reduces blood flow
We knew that marijuana could have a beneficial effect on help brain cells grow to protect it from stress. On the long term, the effects become disastrous, because it reduces the flow of blood to the brain. Which is not without consequences.
Professor Elisabeth Jorandby, co-author of the study, explains that “ As a doctor who sees marijuana users on a regular basis, what struck me was not just the overall reduction in blood flow in these consumers, but the fact that the hippocampus was the most affected region due to its role in memory and Alzheimer’s disease. “
How to maintain good blood flow?
The hippocampus is the area of the brain that acts on memory, learning and navigation. It is the first affected during Alzheimer’s disease. No wonder, then, that those affected have memory problems and are confused. If the hippocampus is poorly irrigated and regularly, the risk of developing this disease increases.
Scientists selected 1,000 regular or occasional smokers and 100 healthy subjects. As a result, not only was the blood flow actually lower in the marijuana smokers, but they also found that the right part of the hippocampus was more affected. ” The use of marijuana can interfere with memory formation by inhibiting activity in this part of the brain. “
