Not exactly HR is it ???, even if I were to hazard an answer for which Effie would slap me on the wrist for i don't know what country your in anyway...this might get it before the close!
Well since we seem to be getting a bit of time before the close Charge in the UK was either Flephedrone or Mephedrone, or god knows what since branded crap like that can have anything in it. Both substances are now illegal in the UK.
I little brwoing of RC sites via Google and a bit of searching on this site should give you the info you seek, but dont expect to be getting a decne t coke substitute legally over the net in the UK.
Unfortnately we are not here to tell you how to get high, Hitman. I agree that UK cocaine is rubbish, but you're going to have to do your own research I'm afraid.. if you find something and you have questions about dosage/safety, feel free to make a thread about it
