Spice usually turns reddish/orangish,and translucent/pinkish crystals when from ultra pure nn xtals.And this pink shift is only after a long time.Never heard of blue spice,but I have a theory.Well the truth is that I once saw Blue spice but it was my pet aardvark making it in a crazy dream I had last year.It was in the middle of a snow storm and Edgar(the Aardvark),being from a hot country,begged me to go get some naptha for him.At that moment I had no vehicle and it was snowing like crazy but I went to the nearest hardware store and asked them for some Coleman Camping fuel .They had it but did you guys know that some if not all by now,is dyed blue just like methanol when bought as fondue fuel.His first pull was a green liquid because of the yellowish spice + the blue dye from the naptha.He also got blue crystals from letting some evapp,and he even got some nice needle like completely clear xtals.So this Topaz is likely just regular spice pulled with dyed coleman camping fuel.If not It might have been extracted pilocin and psilocybin that oxidized and turned blue just like the shrooms do.I read a report long ago in another forum where someone did an extraction and ended up with a mix of Psilocin and psilocybin crystals in thier freebase form . apparently smoking it is far more intense and wierder than DMT.
I tried to say no to drugs but they wouldn't listen
