It isn't spider eggs in my opinion. I was high to the point I was shaking last night which is odd for how little I smoked. I woke up this morning feeling very light. My legs feel very loose and I feel very strange. Oh well, if it really was laced, it's nothing I'm worried about much anymore. Thanks for the help guys, I got all the bits I could find out.

It did spread into a powdery form, I've never heard of sugar not having a taste when eaten, cobwebs spreading into an extremely fine powder, and likewise with the eggs.
