Preparation - Very long, thin, flakey crystals (rather than grains)

[Lettish]

Please, Swim did search but couldn't find any existing threads that were as specific as he would have liked, so that is why he has asked me to post.

Swim scored some ketamine recently that was different in appearance to how he has seen it most times. The ketamine Swim has had before was quite similar to grains of salt or sugar, and were particularly cube-shaped. The ketamine Swim got recently is extremely crystaline and it's very flakey. The crystals are long and thin and some are particularly large. Swims first question is - is this ok?

And now for some other questions on Swim's mind... Should Swim slightly crush these crystals before insufflating? Does the size of them affect administration? Does a bigger crystal take longer to dissolve than a smaller one, and is there a chance it might not fully dissolve? Is it possible to ruin the ketamine by over-crushing? Since the crystals appear to be sharp, can they cut Swim's nasal passages and cause bleeding?

If Swim gets chance he says he will take a picture and ask to upload it.
