Social reward learning starts very early in life. It's quite a claim that MDMA can overcome patterns ingrained during many years. It would have a major effect. But then why wouldn't it work in another setting? It's not as if time is terribly critical: "the MDMA dose did indeed reopen the critical period for social reward learning in the adult mice, beginning around 6 to 48 hours after the dose. The reopening of the critical period lasted at least two weeks, up to around 4 weeks before returning to baseline." The mechanism proposed in the article, basically serotonin, would also affect more than just social reward learning, so how come there's no sign of that? I don't know the target audience of analyticalcannabis.com, but I would need to see much more evidence before writing such a positively worded article.
