Well, god help whoever gets that in their syringe. AFAICT its main 'legit' use was to bring down large animals like elephants, fast, but that seems to have stopped in 2003. It has also probably been used as a chemical weapon in Russia!

I guess it was the next logical step in the "smaller quantities of more powerful stuff are easier to smuggle" race, but I'd expect to see more dealers turning up dead from accidental exposure if it became widespread.
