The scene has always been overrun with recreational substance use, dawg. Partake or not as suits your vibe and life goals, but get ready for it to be a prominent thing among others.

"Influencer types" are new; social media has been corrosive even to this scene as well. A number of clubs in the UK and elsewhere are implementing no-phones policies as a result, so you can dodge some of it by picking venues.

Not sure what part of the world you're from but I'm sure you can find some decent authentic gigs around where people aren't doing it for the likes and follows :)

Honestly, going to a rave with a dancefloor and cool people is kind of lifechanging. It's kind of the environment that a lot of (most?) dance music is made for. Have a great time!
