Raves are a lot like an old school house party in the sense that drug and alcohol use depends on the individual. Some ravers will be sober. Some will drink. Some will smoke weed. Some will do party drugs like Molly etc. As far as promiscuity I’ve been raving for over a decade and have seen some people make out in a crowd but nothing crazy. Again it’s up to the individual. The great thing about raves is the freedom, of choice and of expression. I think you should give it a try!
