This whole thread kinda reminds me of a conversation I had with a friend last night. (Some history: I only started using MDMA in the last 18 months, I live in South Africa where test kits aren't readily available, and it's only after discovering BL that I became aware of the importance of harm reduction/making sure your shit is legit.) So we were chatting about how regardless of where we've sourced our MDMA (or what we think is MDMA/MDxx) - be it dealers we 'know', random dealers at parties (not usually my style, but it has happened), via friends - we've never woken up the next morning and gone, 'Woah, what the fuck did I take?' Yes, I've had one or two less intense rolls, but everything I've ever been sold as MDMA produces the results you'd expect. Anyway, it turned into a long conversation about RCs and the fact that you just can't know without testing - it's as simple as that. The result? Instead of taking the two untested caps in my handbag, we just ended up drinking. +1 to responsibility
