Thanks so much for telling your story.
Having substance testing and trained medics is definitely important at an event where people want to alter their consciousness. GHB is a new name to me but you definitely need educated staff and clear rules at sexually charged events with substance use. It sounds like these spaces are starting to bring in some harm-reduction practices but terrible things still happen at their events and many leaders still try to cover up and blame victims.
Substance use is hard for me to understand since I have not met these people in person, but some Bay Area Rationalists seemed to think that LSD contributed to some bad situations, and reporters talk about workers and executives using ketamine.
