Whilst I rarely use it now, I was a big fan of mdma. I think spice on mdma would be a good experience. Has anyone tried this and if so what is it like? Any physical negatives?

Also, anyone tried on stimulants such as charlie, meph, speed etc? Not intending to try the latter ones, just interested to hear any other experiences.

I'm more intrested in science of the combos over the "ethics" of any particular substance to avoid arguments

To me, i hear "bad news bears" when i think of mdma and spice
