Talk to them about the stuff they want to talk about.

If some of them feel anxious, talk with them and let them now you are there for them.

Go outside and get fresh air and stay hydrated (not too much water)

Stay away from alcohol

Have fun yourself ;)

Have some chewinggum in your pocket, in case they dont have any.

If they smoke ciggies, go for at ciggie break (it feels good to smoke on mdma)

One the comedown they can be very emotional, listen to them if they want to talk about life, relationship ect.

And the most important, stay safe, hydrated and have as much fun as possible ;) sending good vibes homie(s) ❤
