^what are you talking about man? this thread is about mephedrone, not demerol(meperidine).
Uhm actually you're the only one mentioning both demerol and meperidine....

Hmm when I think about it some more, I don't believe mephedrone is worth the addiction potential or the possible disturbing side effects so I'm not going to order more but keep an eye out for glorious methylone.
