I am sort of confused here......have they found all the ricin?? Or is it missing??

Well, the problem is that a thimble full could kill hundreds. That's the impression I get when it was said that an amount the size of a pin head could kill a full grown man.

The Soviet KGB used it in the old days. A little bit goes a long way. No andidote, easily applied.

Ricin is considered one of the most deadly substances in the world.
I believe I read somewhere where one molecule of ricin will kill one cell.
