re: OT scientist- Does mdma disrupt the blood brain barrier?

Ricaurte compared the data from monkeys who were given ecstasy dissolved in a liquid twice a day for four days to other monkeys who received the same liquid WITHOUT the ecstasy twice a day for four days. The study showed that the monkeys who were given ecstasy had damage to the serotonin-containing nerve cells. This damage was still visible seven years later!. Areas that were especially affected were the frontal lobe of the cerebral cortex, an area in the front part of the brain that is used in thinking, and the hippocampus, an area deep in the brain that helps with memory. Although damage was still observed seven years later, it was less severe than when it was observed two weeks after drug use. This suggests that some regrowth could have occurred, but that it is far from complete
