I had some this weekend. Does anyone know what it's made of? Doesn't taste, smell or roll like a pil. Texture, very soft, crushable between fingers. Smelled like faint burnt plastic. Taste like nothing. Round and yellow with "K." Felt like you're on the verge of rolling but don't. It just ends there. Other peeps threw up off of them... was told were suppose to be 90% or more mdma pure. definately did not... know that others in area trying to sell that stuff. my friend was promised 4 star of davids... was given 4 yellow ks. had to call guy back to trade to what he promised. even he didn't want them...
