I think you should use your best judgement with regards to testing at parties. You can do it at parties on the DL, out of the public eye. Everything's online now, so just let everyone know to look for the person wearing suchandsuch a t-shirt if they want stuff tested. Arrange a testing pre-funk party beforehand, maybe.
As for staffing a booth, meh.
A table with the cards and any other flyers you might have made, a water jug, and a t-shirt are often good enough for a party with under 250 ppl. Go, hang out near the table when not dancing, be sure to dance your ass off.
Or sponsor an entire chill room. Pack it with snuggle (futons, blankets, pillows, stuffed animals), put up some deco, offer water, juice and snacks, help throw the party!
If you need anything Kristen (I know you've been talking with Carissa) or just want to chat about stuff, DM me or email me at nathan@_removemefirst_dancesafe.org.
And as for Seagate23, I disagree with your statement that most adulterated pills have a little MDxx present to fool the reagents. As our ecstasydata.org lab testing project has shown, the majority of fake pills have no MDxx in them, and the majority of pills that did test positive for MDMA rarely had other drugs in them. That's for recent test results as well as throughout the life of the project.
We're not trying to change anyone's mind here. We're providing a test they can use to get more info about what they're taking so they can make a more informed decision. If they then choose to take a different substance (that they know more about) or even take the adulterated pill anyway, then that's their decision. You say that a lot of the pills in your area are pipes or just a little bit of MDxx. Maybe you'd like to send in a couple pills from your area to the lab and we could find out?
And maybe back in the 90s the media and cops would freak out if there were a DS booth at a party. That story has already been written, and I don't think there's gonna be a huge media backlash against raves again. OG Ravers are in their 30s and 40s now.
