is sorry to say this..but how on earth can someone identify what this "pink stuff" is exactly when SWIY doesn't even say if its powder, liquid, tablet etc?? Also identifying substances like this is totally a no-no on this forum, it will only be guesses, which could be totally wrong and is a dangerous practice!
SWIM would suggest that SWIY should be more vigilant about what they are taking ... taking a substance that someone doesn't even know what it is is totally reckless, what would happen if SWIY had some kind of reaction that needing medical treatment? The doc
will ask what was taken and his reply will be some "pink stuff" ..
