I lucked out by meeting my partner, and she knew people who were really into the rave scene so I got into raves by going where they told me to go.
However there may be other ways. There might be Facebook groups that advertise raves in your area for example. Event websites, local blogs. You may or may not end up in a good and fun one, but you might end up meeting someone who can point you in the right direction.
One problem you might encounter is age. I find it funner to go to age appropriate events. If youāre in your 30s for example, you probably donāt want to party with 20 year olds. And electronic music culture is old enough that at this point you have people in their 50s still going to raves and doing drugs. So however old or young you are, donāt let that be the barrier.
Molly is something you can only get from a dealer, unfortunately. Thereās a site called RollSafe[1] that seems to have decent information on how to take it safely.
Connecting with people who have taken Molly is easy though. Just come up to them and offer them a friendly hug.
