i was in Ozora , i played in the chillout stage and at the mainstage ...
it is a nice big festival for the psychedelic culture ,
you might be right about the majority of the crowd but not all ,
since a few years these kind of events integrate more & more areas with other things to do than "get high in the dance-floor" ,
i see you are from PT , i guess you know the Boom Festival , this is a good example of a dance party turned into something completely different,

anyway, drugs are everywhere , even your doctor take cocaine for his daily job ... ;)

the social system push the kids into drugs and hardcore behavior on week.ends , so that they can go back on monday morning to be a good soldier ...

i played also a lot of small gatherings , in this places people are looking for different experience ... these are the places where you can find the original vibe of what you talking about ....

Hive account@freedomnation :
ozora never reached 50k , i think the biggest edition was 45k , but yeah ... now is less ... there is more interesting festivals around , also more in the east , before Hungary entered in the Schengen Area , a lot of the east alternative scene was going to Ozora ... now less ... things have changed ...
