Serotonin syndrome is not when you don’t care about wearing an over-the top-outfit to a rave lol. Also Serotonin Syndrome isn’t a chronic condition. Once whatever is causing it is out of the system, you stop experiencing symptoms. Chances are if you’ve done 200mg+ of MDMA in 1 dose you’ve experienced at least a mild to moderate form of SS. There are other ways SS can occur, but in the context of partying I’m pretty sure all of us have overdone the dose at some point and some of y’all still look like Lisa Frank unicorns and sideshow club kids at the function, so idk what this dude is talking about. via @edmhumor comment section
