Pale yellow powder identify

[fail0verflow]

SWIM recently picked up some pale yellow powder from an unknown vendor. The powder soft and no crystals. . Doesn't really have a specific medical taste. SWIM cannot snort it, because the powder is soft, big rocks.
When dropped a bomb of it, a little buzz, feels a little bit like mdma, but far worse, nothing else.
Anyone have any clues what can it be?

No one can answer this for you and taking a random unidentified substance is dangerous. Get an MDMA test kit at least

We don't / can't identify unknown powders based on vague descriptions. Also, drop the SWIM thing. It just makes posts more annoying to read and offers no actual protection. Not trying to be harsh, but please read the rules before posting.
