Please don't use swim, my pet, foaf, or any other stuff like that. We know it's you, it offers no legal protection, makes posts hard to read, and is against the rules.
That being said whatever you do DON'T cut it; it won't be evenly distributed and you'll be putting your self and anybody else who takes it in serious danger. If you can afford 2c-b then you can afford a decent mg scale acurate enough to weigh 2c-b.
I also advise against snorting 2c-b. It works perfectly fine orally.
