I have a lot of experience with LSD so I'm not a total noob in that aspect. Have done my fair share of acid, and hard come ups are not unheard of to me.
I've read quite a bit, but this scenario was just something I was curious of. Since MDMA makes anxiety non existent, I suppose doing it with non close friends is not a problem.
If it's a large House music event then you'll have no problems making new friends. I'd be a little concerned that you don't know exactly what you are taking, but let's assume that it is MDMA then for a first experience you couldn't want for a better location. I'd only suggest a couple of rules to follow…
-Keep your dose manageable. 100mg of MDMA is sufficient for most noobs, with perhaps a redose of no more than 50mg-80mg after your initial peak. This will ensure you are not too overwhelmed in a public space and will limit your comedown.
-Don't keep chasing the high. Accept that the peak is going to last only 4-5 hours. After that redo sing becomes more a sketchy high and greatly increases your risk of either a horrible comedown or more serious long term effects. This means in a day long festival you need to time your dose. Personally I'd enjoy the day sober then drop later in the night, so as to time it for the better acts. Don't get sucked into dipping all day and taking stupid doses above 300mg your first time (or in the future). This isn't lsd or even speed so there are time limits to its effectiveness and safety
-Pace yourself. It can be easy to hit the dance floor for hours at a time and forget to rest. Be mindful of keeping your fluids up and give your legs a break from time to time. If it's a well organise festival there should be plenty of drug friendly installations to enjoy. It will also give you a chance to met and chew the ear off complete strangers. If they are in the same head space they will be more than friendly. There is a reason I have no concerns heading to a party by myself on MDMA, you should have no problems making friends for life from complete strangers.
-Don't ignore the chill out room. It can be tempting to hit the high intensity dance rooms and stomp all night but MDMA is like rolling on an ocean, sometimes the quiet chilled out spaces are just as enjoyable as the high energy ones. A comfy couch with a cold drink as you swim in the tepid surrounds can be some of the best parts of any night out.
-Try and go home a little early and enjoy the afterglow while you are still a little high. This can be the hardest thing to do, particularly if you have spent hard earned dollars on your ticket, but I find nothing good comes from coming down in a cab line. It is one of the reasons I would delay my dose until later in the evening. The more gentle the comedown the easier the crash. * I'm going to assume you and your friends will ignore this the first time but in future when you follow this advice you will no doubt say to yourself, "Shit, that guy was right about getting home a little early and avoiding the sketchy time when the Sun comes up and you are suddenly sobering up surrounded by some seriously ugly people"
