People who smoke marijuana every day have better blood flow and oxygen to the brain, says new study.
According to the researchers regular cannabis users have the most efficient brain blood flow of all, suggesting that the risk of stroke is lowest in them.
The property in marijuana called THC is already known to relax blood vessels and alter blood flow to the brain.
They did this by analyzing the differences in regional brain blood oxygenation and metabolism in chronic cannabis users.
Increased blood flow in the putamen may either reflect the capacity of THC to dilate blood vessels or the development of additional circulatory pathways.
