New and improved Fentanyl test strips

Figured I would share this. I'm not a schill for nor am I advertising for DanceSafe, but they are claiming to sell a improved fentanyl test strips that DO NOT cause false positives for stimulants like methamphetamine/MDMA/cocaine.

Ten of DanceSafe's new fentanyl test strips, including an instructional pamphlet. Reading and understanding the instructions is critical to use the strips.

I knew existing strips were a bit finicky, but only recently learned that stimulants can cause false positives. A friend gave me some of the clearest MDMA crystal I've ever seen, telling me it tested positive for fent. I ran it through GCMS and it came back at 99.99% MDMA, no other substances detected. (I feel kinda bad for those fools in the what's wrong with MDMA thread).

Anyway if the strips are truly better then existing ones, I thought it worth sharing.

These have been out for around a year now. They are clearly better, but I believe still give false positives with diphenhydramine so the advice remains the same, always dilute under 1mg/ml for fentanyl tests, always dilute 10x again if you get a positive result or a result you are not sure about.

All brands of strips are so sensitive to fentanyl that they can pick up just a few molecules, so diluting more will still allow you to detect fentanyl but rule out problems with false positives.
