Jeg fandt lige en ny artikel på MAPS' side, om et nyt forsøg med aber og MDMA som netop er afsluttet. Jeg citerer fra artiklen:
Citat:
If the findings uncovered by Fantegrossi and colleagues can be generalized to humans, then it appears that anecdotal reports of tolerance to MDMA, or its "loss of magic" over time cannot be treated as indicators of harm to the brain. It is not clear what lies behind reduced rates of MDMA self-administration. It is possible that MDMA changes the number or level of activity of specific serotonin receptors, perhaps as a result of repeated stimulation of affected receptors. If the "loss of magic" in humans is analogous to reduced self-administration in rhesus monkeys, then the cause or causes of long-term tolerance to MDMA effects cannot be harm to serotonin or dopamine neurons. Findings reported in this study also suggest that regular ingestion of MDMA may not harm serotonin axons. If this is the case, then taking a few doses of 125 mg (approximately 1.8 mg/kg) MDMA at three to five-week intervals seems especially unlikely to pose any risks of harm to these neurons.
Kort sagt, så konkluderer disse forskere det jeg hele tiden har sagt: at fornuftig brug af MDMA ikke er skadeligt for hjernen!
