agreed with big d man, tried half a green butterfly at yaki last week. not pure mdma, but realitivity good mix of the mdxx substances. quite relaxed, laid back and semi-sleepy. good conversation pill, not as much dancey as many others. my seretonin levels were on full, so smacky effects were at full effect. very much recomend this pill, but reports of green smileys seem to indicate a bit purer mdma pill, but this is just very annecdotal...
