Scientists just found out MDMA (yep, ecstasy) can actually rewire brain systems tied to serotonin and oxytocin—aka the chemicals behind mood and social vibes. They tested it on zebrafish (surprisingly similar to us!) and saw that the right dose made them less anxious and more social. Too much, though, and things got weird. This could mean new treatments for social anxiety or PTSD are on the horizon. Wild, right? #MDMA #MentalHealth #ScienceNews #Health
